Item Name:
Covington Parts - Tumbler V-Belt 1/21 HP
SKU:
COVMVB180
Description:
The Tumbler V-Belt 1/21hp is a replacement V-belt used to transfer power from the motor pulley to the driven pulley in a tumbler drive system. It is a flexible rubber belt with a V-shaped cross section that wedges into matching V-grooves on the pulleys, creating strong friction contact for smooth, efficient power transmission. In lapidary and glass studios, tumblers are often used to polish and finish materials, and a worn or stretched belt can slip, squeal, or cause inconsistent barrel rotation. Replacing the belt helps restore steady speed, reliable torque transfer, and more consistent tumbling results.
How it is used:
- Disconnect power to the tumbler before servicing.
- Remove any belt guard or cover to access the pulleys.
- Relieve belt tension by loosening the motor mount or adjustment hardware, then slip the old belt off the pulleys.
- Install the new V-belt by seating it fully into the pulley grooves, then align the pulleys so the belt tracks straight.
- Set proper belt tension so it does not slip under load, then tighten the mount hardware and test run the tumbler.
