HVAC & Equipment V-Belt B310, Fixes Belt Slipping
Wrapped classical B-section drive belt for fans, blowers, pumps, conveyors, mixers and industrial machinery.
The B310 V-belt transfers motor power to a compatible driven sheave. Match the full original belt designation and the equipment manufacturer's specifications before ordering.
Cross-Reference Information
Length note: The B number is an industry classical designation. Published inside, datum and outside lengths can differ by manufacturer and measurement method. Use the exact marked part number rather than measuring a loose belt by hand.
Common Symptoms
- Belt slips or squeals under load
- Driven fan, blower, pump or conveyor runs slowly
- Black belt dust develops around the sheaves
- Belt is cracked, glazed, stretched or frayed
Check Before Replacing
- Confirm the B-section profile and complete original belt marking
- Inspect sheaves for wear, polishing, rust or dished grooves
- Check shaft alignment and bearing condition
- Confirm the required service rating and tension specification
Installation Notes
- Disconnect and lock out electrical power.
- Relieve drive tension according to the equipment service manual.
- Do not pry the belt over a pulley; create sufficient slack.
- Align the pulleys and set tension to the equipment manufacturer's specification.
- Rotate the drive by hand, reinstall guards, restore power and test operation.
