V-Belt Pulleys for Taper Lock Bushes

Taper Lock SPZ, SPA, SPB, SPC V-belt pulleys for Taper bushes are the basic type of V-belt pulleys. They are produced in standard series and dimensions from gray cast iron. Their design is based on the ISO 4183 (DIN 2211) standard.

The pulleys are mounted to the shafts by means of Taper Lock cone bushings, thanks to which there is not only a fixing on the shaft with a keyway, but also the axial locking against displacement.
