Item Name:
Covington Parts - Tumbler Drive Pulley 1/6 HP
SKU:
COVPUL300-1/6
Description:
The Tumbler Drive Pulley 1/6 hp is a machined drive component designed to mount on the drive shaft of a glass finishing tumbler system. It is constructed to accept a belt and transfer rotational power from the motor assembly into the tumbler’s drive system, keeping the barrel turning at a steady, controlled speed. In glassworking shops, tumblers are commonly used after coldworking steps to smooth and polish glass parts, soften sharp edges, and improve surface finish on small components. A properly matched drive pulley is critical because it maintains consistent torque and rotation, which directly affects how evenly media works across the glass surface during polishing and deburring cycles.
How it is used:
- Install onto the tumbler drive shaft so it can transmit rotation into the tumbler system
- Align the pulley with the motor pulley so the belt tracks straight and runs smoothly
- Use as part of a belt driven system to maintain steady barrel rotation during polishing runs
- Replace a worn pulley when belt slippage, wobble, or inconsistent tumbler speed begins affecting finishing quality
- Support consistent coldworking results by keeping tumbling action uniform across the entire load
