The BANDO b31 is a classical section V-belt designed for industrial drive applications where reliability and long service life are the primary requirements. Classical V-belts remain the standard choice for a wide range of industrial drives, and the b31 delivers consistent power transmission performance across that range. Part of BANDO's Power King series, this belt is built using continuously refined materials and manufacturing methods intended to hold up under sustained operational demands without frequent replacement or adjustment.
The b31 suits general industrial drive setups found in manufacturing, agricultural equipment, HVAC blower assemblies, and similar mechanical drive systems. It is appropriate for both light-duty and moderate-load applications where a classical B-section V-belt is specified. Technicians and maintenance professionals working on belt-driven equipment will find this a straightforward drop-in replacement for worn or failed B-section belts in compatible sheave configurations.
Designed as an OEM-style replacement classical B-section V-belt for industrial drive systems requiring a B31 specification belt.
Belt replacement should be performed by a qualified maintenance technician. Always de-energize and lock out the drive system completely before removing guards or handling belts. Do not force the belt over sheave flanges using tools that could damage the belt body or cords. After installation, verify proper tension and sheave alignment before returning the drive to service.
