SPC Taper Lock V-Pulley, 150 mm PCD, 1 Groove, 2012/2517 bush

These cast iron SPC taper lock V-pulleys suit C and SPC V-belts. The range covers 166 models from 150 to 1250 mm pitch circle diameter (PCD), with 1 to 12 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. Bushes are listed separately on AIMS. The bush series for each model is listed below.

The PCD is the diameter the belt runs on and sets the speed ratio of the drive. Use one groove for each belt.

Key specifications

Selecting and fitting

Choose the pulley by belt section (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. The bush series in the table is the series that fits that pulley, and the maximum bore is the largest shaft that bush takes. Where two series are listed, 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. Tighten the bush screws evenly to the bush manufacturer's torque. Check the two pulleys are in line with a straight edge before fitting the belts.

Set belt tension to the belt maker's recommendation, and check it again after a few hours of running.

Dimensions are as listed for each model and are for reference. Contact AIMS to confirm a measurement if it is critical to your application.
