Covington Parts - Tumbler V-Belt 250

Description:
The Tumbler V-Belt 250 is a replacement V-belt used in a Covington-style rotary tumbler drive system. It is a flexible rubber belt with a trapezoidal V-profile that rides in matching pulley grooves to transfer power from the motor pulley to the drive pulley. In glass and lapidary shop use, a tumbler is commonly used to smooth and finish sharp edges on cut glass, coldworked components, or other shop parts by running them with abrasive media over time. A worn, stretched, or glazed belt can slip, chatter, or reduce torque, so replacing the belt restores consistent drum rotation and more predictable finishing cycles.
How it is used:
- Disconnect power to the tumbler before servicing.
- Loosen the motor mount or tensioning hardware to relieve belt tension.
- Remove the old belt from the motor pulley and drive pulley.
- Install the new V-belt onto the pulleys, ensuring it seats fully in the pulley grooves.
- Re-tension by adjusting the motor position so the belt is snug with minimal deflection, then tighten the hardware.
- Test run the tumbler briefly to confirm smooth tracking and no slipping.
