Steam-Brite Part No. 20260928

This heavy-duty single-groove V-belt sheave is designed for equipment using a 24mm keyed shaft and an A-section V-belt. Its approximately 6-inch size makes it suitable for many motors, pumps, blowers, compressors and other belt-driven machinery.

Please measure before ordering: the actual listed outside diameter is 150mm (5.91 inches), which is commonly described as a nominal 6-inch pulley. Confirm the shaft diameter, keyway, belt profile and available clearance on your machine.

Confirm These Measurements Before Purchase

Measure the shaft with a caliper and confirm it is 24mm.
Confirm the shaft uses an 8mm key.
Verify the belt is an A-section V-belt.
Confirm a 150mm outside-diameter sheave provides the correct equipment speed and belt alignment.
Check hub width, shaft length and nearby clearance before installation.

Installation Notes

Disconnect and lock out all power before working on belt-driven equipment.
Inspect the shaft, key and belt for wear or damage.
Align both sheaves so the belt runs straight without side loading.
Use the equipment manufacturer's belt-tension specification; excessive tension can damage bearings and shafts.
Recheck alignment and fastener tightness after the initial operating period.
