There are many different types of standard and customer-specific toothed belts, each of which has a specific field of application. Toothed belts made from the synthetic rubber polychloroprene, for example, are often used in drives with a higher power transmission. Polychloroprene toothed belts are available in the classic imperial sizes, e.g. MXL, XL, L, H and XH, in the Powergrip HTD variant with 3M, 5M, 8M, 14M and 20M pitches, and in the Powergrip GT variant with 2MGT, 3MGT, 5MGT, 8MGT and 14MGT pitches. All of these belts have toothing encased in nylon, which protects the teeth against wear.


Rubber belts with small divisions are generally used when (positioning) accuracy plays an important role but adequate power still needs to be transferred. On the other hand, rubber belts with large divisions are more suitable for drives that need to transfer high levels of power.


For drives with extremely high torque at low speed, the PolyChain range of toothed belts provides an ideal solution. These can be found in the "PolyChain belts" product group.


The chloroprene toothed belts are also available as open-ended variants; in this form, they can be used in Omega drives. The outer ends of these belt versions are fastened with clamping plates to enable both back-and-forth and up-and-down motion.


Several factors determine which toothed belt type is best suited to a particular drive, for example the application, the power to be transferred, the desired speed (deceleration or acceleration) and the centre-to-centre distance between the pulleys. It is also important to know what ambient conditions are present and whether there are any space limitations.


It is crucial that the toothed belt is pre-tensioned correctly for optimal drive function. The tension can be measured with a testing device such as the Sonic Tension Meter. This device uses the sound waves transmitted by the belt to determine its vibration frequency, which is in turn used to calculate the tension value. As well as ensuring correct tensioning, it is also important that the pulleys are aligned correctly. This is done using a laser-guided alignment system.


Common standards for toothed belt drives are DIN 7721 and ISO 5294. Finally, it is important to consider whether the toothed belts need to be static-conductive to meet ISO 9563 (ATEX environments).

Dear visitor,

How is ERIKS handling the recent developments regarding COVID-19?
The new coronavirus is currently expanding. ERIKS has taken all necessary precautions to protect its employees. The shipment of products ordered on our webshop proceeds as usual.

Which measures has ERIKS taken?

  • ERIKS employees practise the current hygiene instructions as set by the RIVM (including social distancing of 1.5m);
  • All employees essentially work from home, excepting our Logistics department;
  • Picking up your orders from ERIKS locations is no longer possible.

Impact on delivery
Currently the spread of COVID-19 is not affecting the delivery performance of ERIKS. Orders are both handled and shipped normally*. We keep in close contact with suppliers who have production sites in areas struck by COVID-19. When necessary, we will seek alternatives to guarantee our deliveries as well as possible. Generally speaking, our stock is sufficient. However, because the situation in the affected areas can change at any moment the status regarding our delivery remains a snapshot of the current situation.

** Exceptions to this are facemasks, overalls, disinfectants and related hygiene products. Unfortunately, due to a worldwide shortage these products are currently unavailable.
