Item Name:
Covington Parts - Tumbler Wear Washer 1/21 HP
SKU:
COVFWW912-1/21
Description:
The Tumbler Wear Washer 1/21hp is a fiber washer replacement component designed for Covington rolling tumblers and deluxe tumblers. Constructed from durable fiber material, the wear washer serves as a protective interface between the tumbler barrel and the bearing assembly. It reduces friction and wear on the bearing surfaces during extended tumbling operations, extending the operational lifespan of the tumbler's mechanical components.
In lapidary and glass studios, tumblers are used to polish small glass components, stone materials, and metal findings. For lampworkers, this includes finishing edges on coldworked glass pieces, polishing beads and ornaments, and burnishing metal components used in jewelry applications. The wear washer is a consumable part that gradually deteriorates under the constant rotational stress of tumbling. When the washer becomes worn or damaged, it can cause increased friction, vibration, and noise, or allow the barrel to shift out of alignment. Replacing it restores smooth, quiet operation and protects the bearing assembly from premature failure.
How it is used:
- Power down and unplug the tumbler completely before performing any maintenance.
- Remove the tumbler barrel by unbolting or unscrewing it from the bearing assembly.
- Locate the worn fiber washer positioned between the barrel and the bearing surface.
- Carefully remove the old washer, noting its orientation and thickness.
- Clean the bearing surface and barrel mounting area of any debris, dust, or residual fiber material.
- Install the new fiber washer in the same orientation as the original, ensuring it sits flat and fully contacts both surfaces.
- Reinstall the barrel, tightening bolts or fasteners securely but not excessively.
- Test-run the tumbler at low speed to confirm smooth rotation and proper alignment before resuming normal operation.
