Polyurethane V-belts are divided into two groups: PU V-belts that can be used for transport purposes, and PU V-belts for power transmission. This product group contains V-belts for power transmission. The PU belts for transport purposes can be found in our range of weldable belts.


Polyurethane V-belts for power transmission are narrow, heavy belts and are called Polyflex or flank angle 60° belts. These are available in 3M, 5M, 7M and 11M types (nominal upper width of 3, 5, 7 or 11 mm) and contain tension cords made of polyester (PES). A heavy-duty belt version is also available on request.


The polyurethane mixture is stronger than the raw materials used for conventional belts and provides a higher level of resistance to material fatigue and wear. In addition, these belts have a high friction coefficient and a very high adhesion with the tension cords. Furthermore, polyurethane belts are highly resistant to chemicals and oil and very resistant to temperatures of -54°C to +85°C.


All these properties make the Polyflex/flank angle 60° belts a suitable choice for compact drives with small pulleys in combination with high speeds. Accordingly, these belts are especially used in (tool) machines which offer a relatively high performance and high speeds in a limited space. This applies to milling machines, lathes, wood and metal processing machines and small ventilators.


When calculating a Polyflex drive, different factors determine whether a type 3M, 5M, 7M or 11M belt is best, for example the application, the power to be transmitted, the desired speed (acceleration or deceleration), the centre distance of the pulleys and any possible impact loads. It is also important to know what ambient conditions are present and whether there are any space limitations (what is the maximum width and diameter of the pulleys?).


Bekende normen voor V-riemaandrijvingen zijn o.a.: DIN2211, DIN2217, DIN7867, ISO4183, ISO5290 en ISO9981. Verder is het van belang om te weten of V-riemen statisch geleidend moeten zijn volgens ISO1813 (ATEX omgeving).

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.
