Few industries challenge bearings with a

harsher operating environment than the

food and beverage industries. Perhaps no

industry works as hard to meet regulations

governing contamination. When MRC®

introduced the Marathon® series composite

mounted bearing units, it was possibly the

best solution to the problems associated

with bearing failures.

Introduction to Marathon® series corrosion-resistant mounted products and bearing units

Since then, in addition to the composite

units, our XDs—extreme-duty cast stain-

less steel—has been introduced to more

thoroughly meet the needs of the industry.

For extremely challenging applications,

the XDs series provides top-of-the-line

corrosion resistance and the greatest

housing strength available within the

Marathon line. (See page 4 for details.)

At the heart of the Marathon units are

high-quality, corrosion-resistant insert

bearings, available with MRC’s ZMaRC®

coating or with stainless steel construc-

tion. The units’ multifunction rubber seals

are bonded to AISI 304 stainless steel for

superior corrosion resistance, and sealed-

for-life lubricants are USDA compliant.

The Marathon series’ composite housing

resists citric acids, cooking fats and most

chemicals used in food and beverage pro-

cessing. It is constructed of a thermoplastic

composite material that can be up to 61%

lighter than cast iron housings. Its spheri-

cal bore accommodates the insert bearing’s

spherical outer surface, enabling the unit to

fully compensate for initial bearing seating

misalignment.

Plus, the housing is loaded with design

and performance advantages:

• Steel coils embedded in the housing

contribute to the housing’s fracture

strength. Radial breaking load is far

greater than the static load rating of the

bearing. Marathon series housings have

possibly the highest fracture strength of

any composite unit available.

A composite housing with integrated performance features

• A nylon-filled housing base enables the

unit to meet flush with its mounting sur-

face. Flush surface-to-surface mounting

eliminates gaps—potential areas for

contaminants to collect.

• 300 series stainless steel bolt hole inserts

provide added strength to each housing

foot and prevent corrosion.

• Marathon series units are available in

the following housing designs to meet

the needs of most food and beverage

processing applications:

– pillow block

– two- or four-bolt flange

– tapped base

– three-bolt bracket flange

– narrow and wide slot take-up

– low backing height pillow block

– low profile two- and three-bolt flange

– four-bolt piloted flange

– hanger

Extremely challenging applications require

an extremely durable unit—the XDs units.

These housings are AISI 300 series cast

stainless steel with MRC’s proven stainless

steel insert bearings.

The extra strength and toughness of the

cast stainless housings are beneficial where

loads are very heavy or where shock loads

are possible. Also, the safety factor inherent

in the cast steel housing is desirable in

applications where housing failure could

result in injury.

While composite and plated housings are

resistant to most of the chemicals in use

today, these stainless units are not affected

by the strong concentrations of chlorine,

hydrogen peroxide and other chemicals

sometimes used in washdown procedures

The XDs cast stainless housings were

designed especially for use in food and

beverage applications. The bases have no

Marathon XDs unit— MRC’s top-of-the-line units

recesses to trap debris and bacteria; the

exposed surfaces of the housings have no

unnecessary crevices or pockets; and the

smooth finish minimizes material trapped

on the surface allowing a more thorough

cleaning.

Like the other members of the Marathon

family, the XDs series incorporates the

proven insert bearing design and patented

sealing arrangement (see page 5), and are

also greased for life and maintenance free.

Housing styles available include:

– pillow block

– two- and four-bolt flange

– tapped base

MRC XDs extreme duty machined stainless steel mounted units

MRC can also offer additional housing styles

in machined stainless steel. Made of AISI

300 series stainless steel, these units are

machined from solid stainless steel plate

rather than cast. These are especially suited

for applications where surface roughness

is critical, such as instances where chronic

bacterial problems have existed. As with the

cast housings, there are no unnecessary

recesses or cavities to trap debris.

And like the cast stainless units, MRC’s

excellent stainless steel insert bearings are

used.

5

The Marathon units’ high quality insert

bearings are available with MRC’s proprie-

tary ZMaRC coating on the inner and outer

rings. ZMaRC resists frequent washdowns

with water and with acidic and caustic

solutions far better than conventional insert

bearings and conventional coatings, such

as black oxide. That means greater protec-

tion against rust, greater protection against

contaminant-related bearing failure and

greater assurance that your equipment will

pass USDA inspections.

If you prefer stainless steel, MRC will

supply the Marathon series with AISI

420C stainless inner and outer rings and

balls. The insert bearing’s stainless steel

set-screws, positioned 120 degrees apart,

minimize inner ring distortion while main-

taining good gripping strength.

Marathon composite units with ZMaRC-coated bearing inserts are also available from stock with eccentric locking collar mounting.

Eccentric locking collars provide a nearly

360-degree shaft contact for reduced

slippage and improved mounting integrity.

The eccentric locking collar mounting is

primarily intended for use in applications

where the direction of rotation is constant.

This alternative to setscrew mounting also

makes bearing removal easier by providing

access to the setscrew dimple created on

the shaft surface during the initial mount-

ing procedure. The mechanic is then able

to file down the raised edges around the

dimple in order to easily slide the bearing

off the shaft.

Other Marathon style units with ZMaRC

inserts can be ordered with the eccentric

locking collar through our Made-to-Order

program.

Insert bearings

Stainless steel sealing arrangement

A double-protection

seal keeps the Mara-

thon units running

contaminant free.

The sealing arrange-

ment consists of a

double-lip, AISI 304

stainless steel inte-

gral seal, an AISI 304 stainless steel flinger

and a rubber-backed seal gasket. The

flinger and seal’s low-friction rubber lips,

with optimized axial contact, form a double

barrier against pollutants and washdowns.

The seal gasket prevents contaminants

from migrating around the seal insert’s

O.D., and the flinger adds mechanical and

centrifugal protection against contaminant

entry. The space between the insert seal

and flinger is filled with USDA food-grade

grease for even greater sealing efficiency.

USDA-compliant grease

Marathon units are prelubricated-for-life

with USDA H1-compliant grease. The high

quality synthetic grease is odorless and

tasteless, and is approved for use in all food

processing industries.

Other Marathon mounted bearing unit

grease benefits:

• Excellent internal and external bearing

corrosion protection.

• High aging resistance for extended

lubricant life.

• High load carrying capacity, which helps

prevent premature bearing wear.

Secure fit, operator safety

If needed to comply with health and safety

regulations, composite and stainless steel

MRC Marathon units can be supplied with

effective end covers.

ECWM († fig. 1) is for composite and

stainless steel MRC Marathon units. It has

an optional drainage hole that can be easily

opened by the user as required.

ECWM end covers are tested to

withstand 100 bar pressure wash and will

not dislocate during washing.

End covers are not included with the

bearing units and must be ordered sepa-

rately.

End covers

The table below shows the appropriate

end cover for each bearing unit, and the

distance (A5) that the end cover protrudes

from the housing side († fig 2). Prior to

starting the mounting procedure, make

sure to use the correct end cover and check

if the A5 dimension is suitable for your

application arrangement.

NOTE: the end cover must be ordered

separately.

Mounting instructions for end covers

1 Remove the end cover from its package.

2 Identify the housing end cover groove

and make sure it is clean and free of any

debris.

3 Hold the cover askew against the housing

and insert the cover tabs into the housing

groove.

4 Push the cover towards the housing until

all the tabs snap into the housing groove.

Where needed, help the tabs into position

by bending the cover edge slightly as

required.

5 Make sure the cover is securely in place.

If needed, remove the end cap and start

the process again from step 3.

Dismounting instructions for end covers

1 Insert a screwdriver or a pointed tool

into the space between the housing and

the dismounting protrusion located in the

cover side.

2 Unlock the cover by levering it until the

first end cover tabs come out from the

housing groove, then complete the un-

locking process by hand.

HACCP-program compatible

MRC stainless take-up frames help sup-

port the stringent sanitation requirements

of Hazard Analysis Critical Control Point

(HACCP) programs. In addition to being

corrosion-resistant, the frames have no

narrow gaps or crevices that can trap food

contaminants. Also, openings in the side

and bottom of MRC frames facilitate quick

draining during washdowns.

MRC take-up frames are constructed of

304 stainless steel and can be equipped

with Marathon series composite mounted

bearing units. They are designed for

conveyor systems used in meat, poultry,

fruit, vegetable, beverage and other food

industry operations.

Normally employed at the idler end of

conveyor systems, take-up frames support

conveyor shafts and act to produce the

correct conveyor belt tension. Unlike many

take-up frames fabricated on site from

non-stainless materials, MRC stainless

take-up frames feature sturdy single-piece

construction and resist corrosion from fre-

quent washdowns and harsh food industry

chemicals.

MRC take-up frames mount securely to

conveyor systems via four mounting bolts.

The frames and take-up bearing units may

be adapted to fit most existing conveyor

configurations.

Marathon series bearing units

Marathon series bearing units are avail-

able separately and may be mounted in

MRC take-up frames. These units feature

a lightweight thermoplastic housing that

resists corrosion from water, citric acid,

cleaning agents and most other food indus-

try chemicals. The unit’s double-protection

sealing arrangement, consisting of an AISI

304 stainless steel insert seal and an AISI

A D

ECFB

304 stainless steel flinger, protects against

both wet and dry contaminants. The units

are lubricated for life with a USDA food-

grade grease.

Marathon units are available with either

a corrosion-resistant ZMaRC-coated insert

bearing or a stainless steel bearing.

Marathon submersible plane insert bearings (Supplied through the MTO Program)

Set-screw locking

MRC submersible plane bearing units

are suitable for applications, which are

constantly exposed to or submerged in

moisture. When normal anti-friction bear-

ings fail because of grease washout or

corrosion, MRC submersible plane bearings

are the best choice to keep rotating equip-

ment running smoothly. The 316 stainless

steel inner sleeve offers wear resistance

as well as corrosion resistance. The high

performance polymer outer ring allows

the bearing to operate at moderate speeds

without the need for lubrication since

the polymer material is self-lubricated.

Since the polymer material is the friction-

reducing component, no grease is required

for proper performance. And since frequent

regreasing is the typical solution when try-

ing to extend the service life of a bearing in

severe operating environments, excessive

grease purging is no longer a problem. The

insert bearing will not catastrophically fail;

it wears and becomes loose in the bore,

indicating it needs to be replaced.

The polymer material can withstand

continuous temperatures up to 150° F

and tolerates higher temperatures during

washdown. The recommended Marathon

housing material for this insert is either

the composite or cast stainless steel. In

addition, the insert bearing is approved for

direct food contact by the USDA / FDA in

meat, poultry, and dairy applications.

Plane bearing capacity is based on the heat generation, which is directly related to speed versus applied load. The “radial load x speed” column above provides the relation-ship between load versus speed in order to evaluate the bearing suitability. If the application conditions exceed any of the three factors above, different polymer materials can be selected to meet the application needs.

will not catastrophically fail but will exhibit

looseness indicating that the bearing needs

to be replaced. The plane bearing inserts

can be assembled into either the Marathon

ZMaRC-coated cast iron or cast stainless

steel housings to meet most application

requirements for high temperature duty. In

addition, the units meet USDA approval for

direct contact in meat, poultry, and dairy

SKF hi-temp ball bearings and unitsFor extreme operating conditions

SKF hi-temp ball bearing units are fitted

with antifriction bearings that can with-

stand temperatures up to 650° F. Where

normal anti-friction bearings seize, SKF

hi-temp units are a great solution to keep

rotating equipment running smoothly. Their

increased radial internal clearance allows

the bearing to expand without seizing at

extreme temperatures.

Manganese phosphated rings and black

oxide flingers protect against corrosion.

Their special graphite cage provides small

quantities of graphite powder during rotation

to adequately lubricate the rolling surfaces,

making the unit maintenance free, resulting

in significant lubricant savings. Safer oper-

ating conditions also result as grease does

not accumulate beneath the equipment.

And there are no toxic fumes produced by

the grease at the maximum operating tem-

perature range.

The graphite cage and increased radial

internal clearance allow these units to be

run at speeds up to 100 rpm. In addition,

the static load rating is based on an operat-

ing temperature of 300° F. That rating gets

reduced as the operating temperatures

increase up to 650° F.

The SKF hi-temp ball bearing units utilize

the very effective MRC ZMaRC coating for

the cast iron housings to provide corrosion

protection. The units are available in four

housing styles: pillow block, 2-bolt flange,

4-bolt flange, and tapped base. The inch

insert bearings are shown below. The com-

plete unit part number includes the basic

housing style prefix, followed by the shaft

diameter, and finally the suffix “TF/VA228”.

Ex.: 11/2 pillow block for extreme operat-

ing temperatures would be SY 1.1/2 TF/

VA228. The bearings are also available in

metric sizes.

Y-bearings and Y-bearing units for high temperature applications

The SKF assortment of Y-bearings and

Y-bearing units for high temperature

applications, provides solutions for various

temperature and speed combinations.

Y-bearing units are available in three

different designs. All variants are lubricated

for the life of the bearing.

Marathon stainless steel single row deep groove (SRDG) ball bearingsStainless steel single row deep groove (SRDG) ball bearings

Marathon stainless steel SRDG ball bearings

are commonly used in corrosive operating

environments where bearing life is nega-

tively affected by those conditions. They

exhibit significantly longer life than standard

bearings in a wide range of demanding

applications. i.e., food processing, pharma-

ceutical, chemical, or aggregate applications.

For additional protection, sealed and

open bearings can be specified with a solid

oil lubricant that prevents grease washout

during washdowns, and helps protect

against contamination in harsh environ-

ments. Solid oil can be ordered with either

a standard (W64) or (USDA) -grade (W64F)

formula. For example, a 25 mm shaft size

bearing with food-grade solid oil would be

ordered as 205SZZST-W64F.

1) Fillet radius indicates maximum fillet radius on shaft or in housing which bearing corner will clear.2) Rating for one million revolutions or 500 hours at 33 1⁄3 RPM.3) Listed values are for a pressed stainless steel cage; ABEC.1. The speed ratings have been determined through historical application and practice.

Picker hub applicationsStainless steel bearings with solid lubricant pack (W64F)

Single row deep groove (SRDG), doubled

sealed, stainless steel ball bearings are

available with solid lubricant pack in a

food-grade formulation identified as W64F.

This lubricant is USDA approved for use

in food related applications with incidental

food contact. It has excellent oil lubricat-

ing properties and helps prevent grease

washout and contamination under harsh

operating conditions. This lubricant pack

combined with stainless steel bearing

components and synthetic rubber seals,

provides a significant increase in bearing

life in these applications.

Stainless steel single row, deep groove

ball bearings packed with W64F solid

lubricant are shown in the table below. In

addition to the suffix “ST” to denote stain-

less steel, a descriptive suffix “-W64F” is

included to distinguish them from standard

stainless steel bearings. Other sizes can be

furnished on special order.

Technical data

Maximum operating temperatures

The temperature limits, measured on the

bearing outside diameter are:

Maximum continuous: 180° F (82° C)

Maximum intermittent: 200° F (93° C)

Load ratings

Load ratings for bearings lubricated with

W64F solid lubricant are the same as for

standard bearings.

Speed limits

The speed limit Ndm, is dependent on the

bearing bore and outside diameters, and

RPM, in the following relationship:

Ndm =RPM x (Bore + O.D.)

2

(bore, OD in mm)

For double sealed or shielded, single row,

deep groove, stainless steel ball bearings,

the limiting value of Ndm is 240,000.

It is important to note that as ambient or

externally produced temperatures increase,

the maximum operating speed may have to

be reduced, to keep the bearing operating

temperature within the maximum operat-

ing limit. As with most bearing lubricants,

reducing bearing temperature adds to the

capability of W64F.

Step 1

Remove any burrs on the shaft with emery

cloth or a fine file. Wipe the shaft with

a clean piece of cloth. Check the shaft

diameter to ensure it meets the tolerances

shown below.

Step 2

Back out all the set-screws of the double

set-screw unit to clear the shaft and slide

the unit into position on the shaft with

the side opposite the shaft locking device

leading.

Step 3

Make sure the housing base and mating

surfaces are clean and free of any debris

or burrs. Ensure that the supporting sur-

face is flat. If the housing requires shims

for adjustment, the shims MUST extend

the full length and width of the base. Bolt

the housing securely to the support.

(see Table A for maximum recommended

tightening torques for composite housings.)

Note: For composite pillow block and

flanged housings, a thick flat stainless steel

washer should always be installed between

the bolt head and mounting base to prop-

erly distribute the clamping force.

Step 4

ZMaRC double set-screw inserts

Before the set-screws are tightened,

reinspect the position to make sure the

housing did not shift when the base bolts

were tightened. Tighten each set-screw

alternately with the proper hex head socket

wrench until they stop turning and the hex

head socket wrench starts to spring. Refer-

ence Table B for maximum recommended

set-screw tightening torque values and

wrench dimensions. These values should

not be exceeded.

ZMaRC lock collar Inserts

Push the eccentric locking collar in position

on the inner ring extension and tighten

with a quick jerk in the main direction of

rotation of the shaft and then tighten fully

using a spanner wrench or hammer and

drift. Tighten the set-screw with the proper

hex head socket wrench until they stop

turning and the hex head socket wrench

starts to spring. Reference Table C for max-

imum recommended set-screw tightening

torque values and wrench dimensions.

These values should not be exceeded.

Stainless steel inserts

Before the set-screws are tightened,

reinspect the position to make sure the

housing did not shift when the base bolts

were tightened. Remove the set-screws

and apply a bonding agent to the set-

screw’s threads such as LocTite® and

insert the set-screws back into the inner

ring. Tighten each set-screw alternately

with the proper hex head socket wrench

until they stop turning and the hex head

socket wrench starts to spring. Refer-

ence Table D for maximum recommended

set-screw tightening torque values and

wrench dimensions. These values should

not be exceeded.

Mounting the insert bearing into the housing

Position the bearing 90° from its normal position and insert it into

the slots in the housing, making sure that the set-screws do not

interfere with the edge of the housing bore. Then swivel the bearing

into position using a piece of tubing through the bore. If the housing

has a relubrication fitting, the set-screw side of the bearing should

be matched to the side of the housing with the insert slots. In order

to ensure that the relubrication fitting and lubrication holes line up,

the initial misalignment should not exceed 5 degrees.
