As standard, toothed belt pulleys are available in pre-drilled or clamping bush variants. The latter is always used in combination with the corresponding clamping bush, while the pre-drilled models must first be provided with a bore hole and possibly with a key way and a threaded hole.


The most common pre-drilled toothed belt pulleys are available from stock, e.g. the Powergrip HTD, Powergrip GT and PolyChain GT pulleys. Metric pulleys (A and AT) and those with imperial dimensions (XL, L and H) are mostly available directly from our stock in pre-drilled variants. The PolyChain toothed belt pulleys can be found in our "PolyChain toothed belt pulleys" range. Depending on the variant and number of teeth, the pulleys use either flanges and/or a hub as standard. Furthermore, we supply toothed belt pulleys to match customer specifications, and in our turning shop we can machine standard pulleys according to customer requests or designs.


Toothed belt pulleys are mostly made of steel, cast iron (GG) or aluminium (ALU) and are available for special applications in other materials such as plastic or stainless steel. Of course, it is also possible to apply a particular surface treatment to the pulleys if the ambient conditions require it.


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


Common standards for toothed belt drives are DIN7721 and ISO5294. Finally, it is important whether the drive needs to be static-conductive to meet ISO9563 (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.
