Covington Parts - Tumbler Motor Pulley 1/21 HP
SKU:
COVPUL459-1/21
Description:
The Tumbler Motor Pulley 1/21 hp is a precision-engineered drive component designed to mount directly on the motor shaft of a glass finishing tumbler system. It is constructed to accept a V-belt and transfer rotational power from the motor to the tumbler's drive pulley, creating the mechanical advantage needed to turn the tumbler barrel at optimal speeds. In glassworking operations, this motor pulley is essential for coldworking applications where glass components require smoothing, polishing, and edge deburring. The 1/21 hp motor pulley is sized to work with smaller motors and provides the correct speed reduction ratio to ensure the tumbler barrel rotates at the proper velocity for effective media contact and consistent surface finishing across all glass pieces in the load.
How it is used:
- Mount onto the motor shaft to connect the motor's rotational output to the tumbler system via a V-belt
- Work in conjunction with the tumbler drive pulley to create proper speed reduction and torque multiplication
- Maintain consistent motor-to-tumbler speed ratios so polishing media works evenly across the glass surface
- Replace when belt wear, slippage, or motor speed inconsistencies begin affecting tumbler performance
- Support reliable coldworking results by ensuring steady, predictable barrel rotation throughout the finishing cycle
