Tb Wood'S 3V3151 v-belt pulley 3.15 in OD

Application Scope

The Tb Wood'S 3V3151 is a cast-iron v-belt pulley with a 3.15 in outside diameter and a single groove. It suits machinery that requires a 3V or 3VX belt profile and a quick-detachable bushed bore between 1/2 in and 1-1/4 in. Buyers needing a multi-groove sheave or a different pitch diameter will not find a match here.

Build Integration

The pulley mounts on a standard quick-detachable bushing, so no keyway machining or set-screw drilling is required on the shaft. Its gray cast-iron construction handles typical industrial torque loads while the single-groove design keeps the belt alignment straightforward. Systems that demand a fixed-bore or taper-lock mounting style cannot use this unit without modification.

Sustained Operation

Cast iron dissipates heat evenly during continuous duty, reducing thermal expansion that can loosen the bushing grip over time. The material resists wear from prolonged belt contact, maintaining groove geometry through extended run cycles. Applications involving shock loads or abrasive environments may require additional guarding or a different material grade.
