Bestorq B40 Classical Wrapped V-Belt 0.66" X 0.43" X 43"

Designed as a direct replacement drive belt, the Bestorq B40 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. This mid-range length is common on furnace and air handler blowers, rooftop unit supply fans, ventilation fans and small compressors with the motor on an adjustable base near the fan housing. Bestorq builds belts of the same size to run together as a matched set, so the B40 can be fitted on single-groove drives or ordered in quantity for multi-groove sheaves where every belt shares the load. When replacing the B40, 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 B40-BES in the motor and fan parts belts category.
