Super-Torque
SUPERTORQUE timing belts (STD profile) made out of chloroprene are equipped with a high-strength, glass-fibre tension cord boasting a constant length. In order to optimise tracking behaviour, twisted tensile cords running in opposite directions are used as a standard feature. The pre-treatment of these strands guarantees that the back of the belt and the belt's toothed segments exhibit excellent flexural fatigue resistance and also ultimate adhesion to the polychloroprene rubber compounds. The exceptionally abrasion-proof polyamide fabric on the belt's teeth, which takes on a high-gloss character after a short running-in period and which guarantees a low frictional resistance, serves to provide optimal power transfer but with low frictional loss. As a result of specially selected materials that go into their making, SuperTorque toothed belts all have the following standard features:
- Electrostatic conduction
- Resistance to tropical conditions
- Heat resistance from -40°C up to +100°C
- Ozone resistance
- Weather resistance
- Partial oil resistance

SUPERTORQUE TIMING BELTS With The Advantageous Tooth Geometry
- Round edges allow smooth meshing of the teeth
- Large tooth volume and 50% more teeth in the mesh than in a comparable standard toothed timing belt
- Reduced shear force as a result of more even stress distribution on teeth
- High jumping torque and superior smoothness
- Power transmission showing almost no play and with low backlash (SE-Backlash) toothed lock washers

- Lower noise levels
Bare Back Fabric On The Teeth
Since June 2009 all belts with the pitch S2M up to S5M have been delivered with the so-called Bare Back coating on the belt's teeth as a standard. Such a coating is made up of a high-strength cotton fabric, which is not totally soaked in rubber during the production process. The result is that no abrasion occurs on the running side of the belt. "Clean Timing Belts".
The advantages are:
- High degree of wear resistance
- Excellent power transmission
- Low noise levels
- Very little abrasion
- Good protection against moisture and heat
Double-Toothed SUPERTORQUE Timing Belts
-
100 % power transmission on both sides
Inner and outer teeth with shear-resistant and abrasion-resistant nylon fabric reinforcement -
High flexibility for even the smallest washer diameter
Inner teeth are positioned exactly opposite outer teeth -

SuperTorque Order Reference
For double-toothed timing belts the order reference is, for example, DS8M.
The majority of drives in the broad area of mechanical engineering can be reliably designed and implemented using standard belt construction. Polychloroprene synthetic rubber possesses excellent properties with the result that special quality grades are only necessary in very few exceptional cases.
The list of belt lengths in stock is permanently being extended in order to keep pace with customer requirements. You just have to ask for whichever length you need. Intermediate widths not in our standard programme are always available from our stocks for all belt pitches.

When it comes to synchronised belts, the toothed profile of the SuperTorque top-performance timing belt is a patented innovation. The gaps between the teeth on the lock washers of the SuperTorque high-powered belt differ from those on previously designed profiles.
Because of its special shape, the profile formed by the spaces between the teeth guarantees optimal meshing of the timing belt teeth. The depth of the space between each tooth is less than the height of the teeth making up the SuperTorque high-powered belt. And this, together with the arched curvature of the gap between each pulley washer, means that tension is spread more evenly over the entire stretch of belt teeth.
Tooth Lock Washers with SE Tooth System
For all those timing belt drives which demand the highest level of synchronicity, such as
- Robots
- Handling Devices
- Machine tool feeds
- Printing machines
- Writing computers
- Optical readers
and the like, we recommend tooth lock washers with an SE tooth design. The gaps between the teeth, which are meticulously formed by means of special milling machines, enable the SuperTorque timing belt drive to be virtually free of any kind of play. This SE tooth system is available for the standard profiles of S2M, S3M, S4.5M, S5M, S8M and S14M.

SuperTorque top-performance timing belts are produced with the highest degree of precision. Manufacturing tolerances as regards length, width and thickness are minimal and are determined in line with commercially profitable manufacturing processes. Should, however, narrower tolerances be absolutely essential, we recommend a technical consultation with us on this issue.
Gap Profile of Tooth Lock Washers
It is imperative that the gaps between the teeth of the washers making up the SuperTorque timing belt correspond exactly to the pitch and that they are manufactured according to the recommended range of tolerance. Only by adhering to the specified dimensions can utmost strength and smooth running with virtually no signs of play be guaranteed for the SuperTorque timing belt.
Tooth Lock Washers - The Materials
The most diverse types of materials, such as sintered metal, plastics, aluminium, steel, grey cast iron and cast steel, can be used to make tooth lock washers. But the material is primarily chosen so as to best suit the intended use and the demands in question, whereby particular attention should be paid to ensuring that adequate resistance to wear is present. In the case of substantial series production requirements, manufacturing tooth lock washers using the full mould process (injection moulding or pressure die-casting) is the most appropriate method.
Flanged Wheels
Flanged wheels or pulleys prevent the wearing down of timing belts. It is necessary that at least one of the tooth lock washers - for cost reasons usually the smaller one - is fitted with 2 flanged wheels. The mounting of 1 flanged wheel on both sides of each tooth lock washer is also possible. With drives having a centre distance greater than 8 times dw, it is recommendable to attach 2 flanged wheels per tooth lock washer.
Parallelism
The teeth should run parallel to the axis of the borehole with a maximum deviation of 0.001 mm per millimetre of the width.
Conicity
The conicity can only amount to a maximum of 0.001 mm per millimetre in the head width and, at the same time, is not to exceed the permissible diameter tolerance.
Surface Quality in accordance with ISO R 468
The surface quality is not to exceed the value of Ra=3,2 µm for tooth flanks and tooth crest.
Balancing
With tooth lock washers that are processed on both sides, balancing is usually not necessary up to a peripheral velocity of 30 m/s. But cast discs are even to be balanced at v < 30 m/s.
The following is a general rule of thumb:
- Balancing in one plane, quality level Q 16 in accordance with VDI 2060 at v = 30 m/s for dw>400 mm or at n = 1500 min-1 for dw 400 mm.
- Balancing on two planes with the recommendation Q 6.3 at v > 30 m/s or at v> 20 m/s at a ratio of effective diameter to tooth lock washer width < 4.
Balancing is carried out on ungrooved tooth lock washers by means of a smooth balancing mandrel.
Further details can be found in ISO 254 and in the VDI Guideline 2060.

In order to achieve optimal performance and as long a service life as possible, timing belts have to be correctly installed, correctly tightened and correctly aligned. Prior to installation, it is always recommendable to inspect the belts for any possible damage resulting from transport or storage.
The Correct Mounting
Pulleys and, of course, belts themselves always have to be mounted with the correct alignment. This means that belts cannot be bent or buckled in any way, which could lead to a drop below the minimum permissible pulley diameter. That corresponds to approximately 50 mm for belts with a pitch of 8 mm and about 125 mm for those belts with a 14 mm pitch. Imbalanced drives cause a variety of belt tension problems and edge stresses and are also responsible for extreme lateral movement, the undesired wobble. All this leads to increased operating noise and more wear and tear on the belt. Therefore the parallelism error of the pulleys should only amount to a maximum of 0.5% of the centre distance. Angle accuracy is to be maintained by keeping misalignment down to 0.25° at the very most.
Pre-Tensioning The Belt Correctly
Firstly the belt always has to be tightened in line with the calculated pre-tensioning force and checked after a running-in period of about 5 minutes. The belt is then to be retightened according to the relevant value, should it have shifted or altered its position in any way. Finally after a further 8 hours of operating, the belt is to be once again inspected and, if necessary, tightened to comply with the required value that has already been calculated.
Causes of failure and corrective measures can be found in the following document:

Timing belts transmit tensile strength without slipping with the result that the greatest longitudinal force or pull determines the width of the belt. With drives where operating conditions are characterised by jerky movements and impact, it is recommended to take a load factor of c2 = 2.0.
Service factor c0 = c2 + c3 | |||||||||
Load factor c2 | Examples of drive units | ||||||||
Electric motors with low starting torque (up to 1.5 x nominal torque) e.g. DC shunt motors, combustion engines with 8 or more cylinders, water and steam turbines | Three-phase and AC motors with normal starting torque (1.5-2.5 x nominal torque) e.g. DC shunt motors with compound winding, squirrel cage motors, combustion engines with 4-6 cylinders | Three-phase and AC motors with high starting and brake torque (exceeding 2.5 x nominal torque) e.g. single phase and synchronous motors with high torque, combustion engines up to 4 cylinders | |||||||
