Synchroflex timing belts are made from a wear resistant Contilan polyurethane with
high quality steel tension members. The excellent bond between the two creates a belt
with high load bearing properties and exceptional span rigidity which means no post
elongation. The moulding process produces close tolerance timing belts allowing them
to be run smoothly at high rotational speeds. Synchroflex belts can also be used for
indexing and conveying and can also have lugs welded to the belt back.
Properties:
positive fit, synchronous operation
low noise
constant length, no post elongation
maintenance free extremely wear resistant
efficiency up to 98%
highly flexible
belt speeds up to 80 m/sec
temperature range -30 to + 80C
temporarily higher than 120C
resistant to fats, oils and petrols
resistant to some acids and alkalis
hydrolysis resistant
low tension
high positional and angular accuracy
Breco belts come in three styles.
Breco-M:Open length belting mainly used for linear drives. Reels are extruded to 50
and 100m lengths, although shorter lengths can be cut.Breco-V:Joined to length belting are made from lengths of Breco-M and are used
for indexing, conveying and power transmission applications particularly when long
centre distances are invloved. Profiles and backings can also be applied to these belts.
Brecoflex:Fully moulded endless timing belts used for power transmission
applications. These belts have no joint and a continuous steel tension member.

Linear drives often require extremely high postioning repeatability and accuracy. Breco ATL belts are
optimised for linear drives. ATL belts are available in open reels and cannot be joined. They are connected
using clamp plates and/or tension plates.
These belts use extra strength high flexibilty tension cords, designed for increased pre-tension, yet are
suitable to run in standard AT pulleys. They are manufactured to a negative length tolerance, so that the beltand pulley mesh correctly when the belt is under pre-tension and working load.

Angular Drives Synchroflex, Breco, & Brecoflex belts can be used in angular drives as a crossed
(twisted) drive but not as a radially displaced drive.
With crossed timing belt applications, the outer tension members suffer greater elongation
than the middle ones.
At a ratio of IT > 20b there is no power reduction and no special design considerations
need to be made.
If a ratio of IT< 20b is necessary, please contact our technical department.
Two Axis Angular Drive Three Axis Angular Drive
Flanges Timing belts must be guided with flanges to eliminate the wandering off effect of side loads
and as a rule this is done with flanges.The correct design of the belt guiding system
incorporating the minimum of side loads and frictional losses is of fundamental importance
for a trouble free drive. The direction of rotation and the span length are of equal importance.
Idler pulleys can be used to guide the belt. An idler pulley is
usually positioned next to the drive pulley especially where there
is a long span length. The idler pulley is preferably postitioned on
the slack side of the drive.
It is more cost effective to have flanges on the small pulley
rather than the large one.
With bi-directional drives, the idler pulleys should be positioned
in the middle of the span length. Short span lengths before the
belt lead-in should be avoided.
Belt width(b) relates to the pulley width(B) to give sufficient side
clearance. This clearance is not specific. See pages 4 to 19 for our
standards.

Initial Design Drive parameters must first be determined, thus establishing the belt pitch, length, and size
of pulleys. Profiles can be welded to any pitch belt.
For transport applications it is advisable to use Breco belts with PAZ nylon coating(see page
29). This coating gives a reduced frictional coefficient, thus better running and less wear
when used with support plates.
Profile Material Polyurethane (92 shore). The same material used for the Breco/Brecoflex belts.
Profile and BeltPitches
If possible the pitch of the profiles should be a multiple of the belt pitch. If this is not possible,ensure that the sum of the profile pitches is equal to the belt length.
Synchroflex and Breco belts can be supplied with special profiles on the back to offer designers infinite solutions
to conveying, handling, and postioning drives.
Profiles are thermally welded to the belt back according to customer requirements.
The standard pitch tolerance of profiles is 0.5mm.
Positioning of Profile The belt flexibility relies on the tooth gap. In order to maintain the belt flexibility around the
pulleys it is advisable to position the profiles over the belt teeth.
Choice of Profile The type of product to be conveyed and the method of transportation will influence thechoice of profile.
Standard profiles. See page 28.
Profiles cut from sheet polyurethane.
Special profiles can be made from a new mould. There will be a tooling charge for this
service.

Tolerances The standard pitch to pitch tolerance between profiles is 0.5mm. Standard height tolerance
is -0.5mm.
Ordering Example A drawing of the profiled belt is preferred when ordering.
However a profiled belt can be ordered by description.
e.g. Breco belt 50T10/5000-V-PAZ-FN100 profile type 2.3.3.015.008
profile pitch 50mm over tooth form.
Flash Flash occurs between the belt back and the profile as a result of the welding process. The
flash radius can be between 0.5 and 2mm depending on the profile size and thickness.
If the flash will impair the function of the profile, please order with flash removed

Number of teeth in pulley
Profile Thickness
Example for determining the profile thickness on a T10 belt running around a 20 tooth
pulley.
For profiles over tooth form, profile thickness 8mm
For profiles over tooth gap, profile thickness 3mm
NB. With intermediate sizes (eg 22 teeth) it is recommended to take the max. profile
thickness from the nearest smaller size.
Profiles with Reliefs The flexibilty of the belt will not be affected if reliefs are designed into the
profile.
The belt flexibility can be affected by the profile thickness. As a rule the thickness should be
as small as possible. The following table represents the relationship between profile
thickness and the chosen pulley size.

New high performance
polyurethane
Gen III Synchroflex Generation III timing belts.
The new generation Synchroflex belts. Improve power transmission by up to 25%.
Improved tracking. Less flange wear due to bifilar steel cord tension members. Running noise is minimised by using a smaller belt width. Belts are currently available in AT style only. High performance red polyurethane
E Tension members The thinner the individual wire the greater the flexibility of the belt. With E tension membersthe reduced cross section allows more individual wires and therefore reduces the tensilestress in the tension member. The advantage of E tension members is a reduction inminimum pulley and idler diameters for reverse bending drives, due to the better fatiguestrength. The smallest pulley diameter can be reduced by up to 30% over standard tension
members. Belts with E tension members are recommended for multi-shaft drives withsevere reverse bending (contraflexure).
Available Pitches: AT3, AT5, AT10, AT20, T5, T10, T20
Summary.
thinner individual wires in the steel tension member. higher dynamic capabilities. Extremely high fatigue strength under reverse bending. Longer l ife Smaller pulley and idler diameters.

Anti-static Belts The use of timing belts will always lead to static emissions being generated by the two
moving surfaces of the pulley and belt.
A special conductive coating can be applied to polyurethane belts for when static electricity is
undesirable. Problems that may arise from static discharge are:
Interference with electronic equipment.
Risk of ignition or explosion of flammable materials.
Risks of shock to the operator from high voltages which can be generated.
Properties of Anti-static belt
Surface resistance R of 106 Ohms.
Black in colour.
Ordering Example: 25T5/630 Anti-static coating.
Nylon Coating A nylon fabric coating extruded during manufacture, can give a reduced coefficient of friction,
facilitating easier meshing with the pulleys and a reduction in noise. This coating is ideal for
transport applications when suppport plates or guide rails are used.

Synchroflex kevlar cord belt with teeth reworked.
Linatex backing mechanically reworked with grooves and holes for
vacuum application.
Back Cross Milling
Back cross milling enhances belt flexibilty. Milled grooves are used to improve safe loading and secure
positioning of the products on the belts.
Synchroflex, Breco, and Brecoflex belts can be mechanically reworked for special applications in handling and transportation.
Belts with a thicker back are especially suited for reworking. Please not that belt flexibilty is greatly reduced with a thicker backed
belt. Cross grooves can be ground into belt to help improve flexibilty.
Back Longitudinal Milling
Belt back shaping offers a wide variety of designs. A profile can be machined precisely for the function
required. Dimensions are to be indicated as depth measure x in relation to the belt back.
Back Grinding
The backs of all Brecoflex timing belts are ground. For reasons of precision or in order to obtain a
roughened surface, all other timing belts of the Synchroflex and Breco delivery range can be ground. Here
the overall thickness x must not fall below a minimum thickness, otherwise the tension members could be
damaged.
Removing Individual Teeth
The removal of individual teeth or groups of teeth is possible and practical due to the high dimensional
precision meshing, when the remaining teeth are to serve as precise position load areas.
Holes In Timing Belts
Holes can be drilled into timing belts for purposes of vacuum or air film conveying, and as clearance for
assembly mechanisms. Holes can also be used to attach stops and cams.
Standard hole tool diameters are 2, 2.5, 3, 3.5, 4, 4.5 ,5, 5.5, 6, 7, 8, 9, 10, and 12.
Other holes and rectangular holes available on request. Tooling charge may apply.

The MULCO tension roller Type M is an innovative development. It is available in 7 standard sizes. The tension rollers aredistinguished by a rigid, vibration-resistant load bearing design. The forces acting by the belt pull are reliably absorbed by thegenerously dimensioned D1base diameter. The ball race and the load bearing structure are made of AlCuMgPb (F38). The tensionrollers are over-mounted on the machine wall. The eccentrical fitting results in an easy adjustment of the belt pre-tension force. Toensure the swivel motion around the mounting axle, the face spanner (pictured below) can be used.
The MULCO tension rollers are fitted with high quality grooved ball bearings. The first filling of the bearings consists of a high-performance lithium saponified grease to ensure life time service. The greases are short-time temperature resistant up to 120C.Permanent temperatures of 70C and above will lead to a reduced useful life of the grease. The stated load bearing parametersrefer to the entire tension roller on the basis of a centred belt load.

Slider beds are available as a standard range, matched to the timing belt width. The preferred delivery length is 2000 mm. Cuts tolength shorter than 2000 mm are available. The material ia UHMW polyethylene. This material has a low friction coefficient and isalso wear resistant. The sliding friction value between standard polyurethane and low-pressure polyethylene is ~ 0.3.The C profile is made of zinc plated sheet steel. The cut out is intended for fastening screws. The C profile has no bore holes.Due to the relatively large expansion of the sliding material under temperature, provide expansion gaps on the rail stucture.
Approximate formula for the linear expansion is 2mm/10C temperature difference over 1000 mm of length.
