Metric wedge belt pulleys SPZ, SPA, SPB, and SPC are suitable for both classical and wedge belts Z/SPZ, A/SPA, B/SPB, C/SPC respectively.
SPZ pulleys can be used with 3V/9N belts, and SPB pulleys can be used with 5V/15N belts. In these cases, they should be applied on both the driving and driven pulleys in order to achieve the same groove distance.
TaperTiteTM bushings are used on the entire range of standard pulleys, enabling quick and easy mounting and removal from the machine shafts. Convenient to re-install old pulley on other shafts of different diameter by fitting same TaperTiteTM bush number but with different bore. Alternatively, QD bushings or Shaft Locking Assemblies can be custom designed to fit with any pulleys.

- In general, pulleys quality, finish and balance comform to ISO 254:1990. Pulley surface is phosphated to prevent rust.
