MicroPoly Composition
• MicroPoly is a microporous polymer lubricant. It is a mixture of:– Plastics– Oil– Other additives
• MicroPoly is over 50% oil by weight.
PhyMet, Inc.
MicroPoly is a “Sponge.”
When friction or heat is applied, the “sponge” weeps oil to the surface. This provides constant, consistent lubrication as the bearing rotates.
When the bearing is at rest, oil can be reabsorbed by the MicroPoly.
PhyMet, Inc.
MicroPoly Applications
• Ball and roller bearings
• Linear bearings
• Ball screws
• Roller chain lubrication
• Bushings
• Wheel flanges
PhyMet, Inc.
All Types of Bearings
• Ball bearing inserts
• Ball thrust • Cam followers• Cylindrical roller • Double row ball• Housed ball • Housed roller
• Needle roller• Roller thrust • Single row ball• Spherical roller • Split roller• Tapered roller • Trolley wheels
PhyMet, Inc.
Filled Bearings
MicroPoly-filling bearings does not alter the dimensional tolerances of the bearing in any way. As you can see below in the tapered roller bearings, the MicroPoly simply fills the spaces between the rollers and the cage.

When should you use MicroPoly?• When bearings are failing due to:
– solid contamination– liquid contamination– lack of lubrication– over lubrication
• When conventional lubrication contaminates the end product or causes safety hazards.
• When labor or down time costs are substantial.
PhyMet, Inc.
Benefits of MicroPoly Lubrication
• Reduces costs associated with labor or down time due to bearing failure
• Reduces contamination • Provides a maintenance-free bearing• Extends bearing life• Improves housekeeping by eliminating the
dripping of grease and oil
PhyMet, Inc.
Benefits, cont.
• Reduces scrap rate of parts caused by lubrication dripping onto parts
• Provides lubrication to difficult to reach applications
• In most cases, automatic lubrication systems can be eliminated
PhyMet, Inc.
MicroPoly vs. Conventional Lubrication
• Grease - about 35% oil suspended in a thickener
• MPL - over 50% oil• Grease - bearing is filled 1/3 to 1/2 full.
Overfilling can cause churning.• MPL - bearing is filled 100%. More oil
is available for lubrication. Due to solid structure, there is no churning.
PhyMet, Inc.
Limitations
• Temperature Limitations – see Cross Reference Guide
• No direct contact with– Acids– Strong detergents
• Speed Limitations
All new applications should be reviewedwith PhyMet personnel.

Bearing Type Ndm
Max RPM = Ndm/(0.5*(Bore + OD)) in mm
PhyMet, Inc.
Example
Single row ball bearing, metal cage:Bearing number: 6210Ndm Value: 300,000
Max RPM = 300,000 = 4,287 RPM0.5*(50+90)
Single row ball bearing, plastic cage:Bearing number: 6210Ndm Value: 40,000
Max RPM = 40,000 = 571 RPM0.5*(50+90)
PhyMet, Inc.
Original Equipment Manufacturers
Application: Steering columns in trucksBearing Type: Tapered roller thrust bearingProblem: Due to severe road conditions dirt,
water, and road salt contaminatedthe bearings. Warranty requirements were not being met.
Results:Over 150,000 of these bearings have been filled over 8 years, with no failures reported. Warranty requirements are being met.
PhyMet, Inc.
Automotive Industry
Application: Towmotors, front wheel spindlesBearing Type: Tapered roller bearingsConditions: Heavy load. Bearing life 3 - 12
months.
Results: Bearing life extended to 3.5 years. The automobile company saved $337,134.
PhyMet, Inc.
Power Generating Industry
Application: Coal pulverizer grinding wheelBearing Type: Tapered roller bearingsProblem: Coal dust caused bearing seizure,
resulting in the dust igniting. Bearing life 9 months.
Results: Bearing life extended to 10 years. Fires were eliminated. The company saves $250,000 per year.
PhyMet, Inc.
Food Processing Industry
Application: Feather picker, chicken processingBearing Type: Single row ball bearingProblem: Washdown of the bearings with
water and detergents causes premature bearing failure. Bearinglife 3-4 weeks.
Results:So far bearings have lasted 9 weeks and are still running. Estimated savings $170,000.
PhyMet, Inc.
Food Processing Industry
Application: Potato chip sizerBearing Type: UC205-16 Ball insert bearingProblem: Salt and other seasonings
contaminated the bearings. Bearinglife was 6-8 weeks. Downtime costsare $25,000 per hour.
Results:Bearing life has been extended to 18 months.Estimated cost savings over a 6 year period: $4,000,000.
PhyMet, Inc.
Metal Processing Industry
Application: SealMaster SFT 35E – 2 7/16” boreBearing Type: Housed ball bearing, 2-bolt flangeProblem: Buried in sulfur-contaminated sand.
Bearing was contained with an end cap. Temperature 110°F. Bearing life 6 months.
Results:Bearing life is now 12 months and the greasing schedule has been reduced. End cap was eliminated.
PhyMet, Inc.
Earth Moving Industry
Application: Trenching EquipmentBearing Type: Guide wheels and idler wheels,
22308 spherical roller bearing (axlebearing), FYRP 2 ½” roller bearing
Problem: Trenchers run in dusty, dirty, muddyconditions. Dirt and mud are pulledup into the bearings.
Results:Life of the idler wheels and axle bearings was extended from one month to one year. Life of the FYRP bearing was extended from 2 months to 2 years.
