Bestorq B123 Classical Wrapped V-Belt 0.66" X 0.43" X 126"

Designed as a direct replacement drive belt, the Bestorq B123 classical wrapped V-belt serves a wide range of belt-driven HVACR and plant equipment. Typical uses include supply and return fan blowers, air handling units, packaged rooftop units, make-up air units, exhaust fans and belt-driven compressors, along with pumps, conveyors and general shop machinery. The treated fabric cover resists oil and heat, which suits mechanical rooms and rooftop equipment where belts run warm and collect grime. Very long lengths like this are usually found on large industrial fans, cooling towers, agricultural equipment and conveyors with wide centre distances between the motor and the driven sheave. Bestorq builds belts of the same size to run together as a matched set, so the B123 can be fitted on single-groove drives or ordered in quantity for multi-groove sheaves where every belt shares the load. When replacing the B123, inspect the sheaves for wear, check alignment and set tension to the equipment manufacturer's recommendation. Replace all belts on a multi-groove drive at the same time. It is listed by RSL as SKU B123-BES in the motor and fan parts belts category.
