V-Belt Pulley with Quick Detachable Bushing

The Tb Wood'S 3V651 is a single-groove V-belt pulley designed for power transmission applications. It accepts bushings with a bore range of 1/2 in to 1-5/8 in for flexible shaft mounting. This component suits maintenance teams and machinery builders who need reliable belt drive alignment. Buyers needing multi-groove configurations or different pitch profiles should look elsewhere.

Steel Construction Handles Operational Loads

The steel body dissipates heat generated during continuous power transmission without active cooling. No fan or lubrication system is present so noise is limited to belt mesh and bearing sound. Power draw depends entirely on the driven load and motor sizing rather than the pulley itself. The quick-detachable bushing allows removal without heating or hammering.

Single Groove Matches 3V and 3VX Belts

The 6.5 in pitch diameter suits 3V and 3VX section belts for standard industrial drives. Quick-detachable mounting means the bushing seats in the pulley taper and clamps to the shaft with set screws. One groove limits the assembly to a single belt so capacity scales with belt rating not pulley count. Shaft keyway and bushing selection remain the installer's responsibility.

Questions about this item

How is the quick detachable bushing installed on the 3V651 pulley and what step is often missed?

Insert the bushing into the pulley bore, align the holes, then tighten the set screws evenly to the specified torque so the bushing grips the shaft uniformly.

What maintenance or replacement will the 3V651 V-belt pulley need over time?

Inspect the single groove for wear and the bushing bore for fretting; replace the belt when ribs crack or stretch and the bushing if the keyway walls deform.

What limit appears first on the 3V651 pulley during sustained operation?

The 6.5 in pitch diameter caps belt speed, so prolonged high RPM runs heat the groove walls until the belt slips or the bushing loosens.
