Industrial V-Belt Pulley

The Tb Wood'S 5V1873 is a 3-groove V-belt pulley built for power-transmission drives that use 5V or 5VX belts. It suits maintenance teams and OEM assemblers who need a quick-detachable bushed bore for fast sheave changes on conveyors, fans or pumps.

Quick-Detachable Bushing Mount

The pulley accepts a standard QD bushing with a bore range of 7/8 in to 3-1/2 in, so the same sheave fits several shaft sizes without re-machining. Three grooves distribute load across multiple belts, reducing slip and extending belt life in high-torque applications.

18.7 in Pitch Diameter Performance

At 18.7 in pitch diameter for both 5V and 5VX profiles, the sheave runs at moderate rim speeds that keep vibration and bearing loads low. The cast-iron construction dissipates heat evenly, so the drive stays cool and quiet during continuous duty cycles.
