Finer Power taper Lock V-Pulleys, 106 / 4

This is a clearance item and is sold as-is. No returns or exchanges apply. This page covers the Taper Lock V-Pulleys, Cast Iron, SPZ, SPA, SPB and SPC (Clearance), available in 8 pc diameter (mm) options: 85, 106, 132, 140, 170, 180, 200, 236.

Note: Pulleys are dirty and old, but they shouldn't affect performance. These cast iron taper lock V-pulleys are clearance stock. The 10 models cover SPZ, SPA, SPB and SPC V-belts, from 85 to 236mm pitch circle diameter (PCD), with 1 to 5 grooves. Each pulley has a tapered bore that takes a taper lock bush. The bush is machined to your shaft size and keyway, and locks the pulley on the shaft when its screws are tightened.

Choosing the right option

Choose the pulley by belt section (SPZ, SPA, SPB and SPC), pitch circle diameter and number of grooves. Divide the driven PCD by the driver PCD to find the speed ratio.

Then choose the bush. Where two series are, either fits. Order a bush of that series with the bore and keyway you need: see the metric cast iron taper lock bushes or imperial cast iron taper lock bushes.

Fit the bush in the pulley hub, slide the assembly onto the shaft and align the pulley with its mating pulley. Check the two pulleys are in line with a straight edge before fitting the belts.
