Quick Detachable V-Belt Pulley

The TB Wood'S 3V531 is a single-groove V-belt pulley designed for power transmission systems using 3V or 3VX belts. It accepts a Quick Detachable bushing with a bore range of 1/2 in to 1-5/8 in, allowing fast shaft mounting and removal without special tools. Maintenance teams and machinery builders use it to drive pumps, fans and conveyors where rapid change-outs reduce downtime.

Verify Bushing And Belt Compatibility

Confirm that the existing shaft diameter falls within the 1/2 in to 1-5/8 in bushing range and that the installed belt profile matches 3V or 3VX specifications. The pulley pitch diameter is 5.3 in for both profiles, so speed ratios depend on the mating sheave. Ensure the bushing type is Quick Detachable; other bushing styles will not seat correctly.

Steady Load Operation

Under continuous duty the cast-iron construction dissipates heat evenly and maintains the 5.3 in pitch diameter without distortion. The single groove keeps belt alignment stable during long runs, reducing vibration and extending belt life. The Quick Detachable bushing remains clamped under sustained torque, preventing axial shift that can occur with set-screw hubs.

Questions about this item

What is included with the Tb Wood'S 3V531 pulley and what must be purchased separately?

The pulley is supplied as a single 1-groove sheave with a Quick Detachable bushed bore. A compatible QD bushing and 3V or 3VX belts are not included and must be bought separately.

How do I choose the right bushing for the 3V531 model?

Select a Quick Detachable bushing with a bore range of 1/2 in to 1-5/8 in that matches your shaft diameter. The pulley accepts standard QD bushings, so match the bushing size to your shaft.

What does the 5.3 in pitch diameter mean for belt speed on the 3V531?

A 5.3 in pitch diameter on 3V and 3VX belts means the belt travels at a speed determined by shaft RPM multiplied by 5.3 in. This diameter sets the drive ratio when paired with a driven pulley.
