Pulleys


Belt performance is highly dependant on pulley performance. High quality pulleys significantly increase belt life and reduce the total cost of ownership of your machinery.

At SKF, we offer a range of pulleys which are:

  • Manufactured according to relevant ISO or RMA standards to ensure optimum performance
  • Statically-balanced to G6.3 balancing quality
  • Equipped with taper bushes for quick and accurate installation
  • Phosphate-coated for corrosion resistance

SKF also offers a range of pulleys in all belt profiles, with plain, taper bush or “QD” configuration. Friction type locking assemblies are also available on request.

Classical and trapezoidal inch pitch timing pulleys (MXL, XL, L, H, XH, XXH) are manufactured according to ISO 5294. Metric pitch series timing pulleys (T/AT) are manufactured according to DIN 7721. All SKF V-belt pulleys are manufactured to the standards ISO 4183, DIN 2211, ANSI Narrow V-belt pulley IP-22 and the ANSI Classical V-belt pulley IP-20. They are interchangeable with type SPA, SPB, SPC and SPZ. All pulleys are statically balanced to G6.3 according to ISO 1940. After balanced the pulleys are suitable for the linear speed of not more than 35 m/s. Two Plane (Dynamic) balancing can be provided on request. SKF can issue a certificate stating that all pulleys are dynamically balanced in case of any special customer request.
