Bestorq BX90 Cogged Raw Edge V-Belt 0.66" X 0.43" X 93"

The Bestorq BX90 cogged raw edge V-belt is a replacement drive belt for motor and fan assemblies where a standard wrapped belt struggles on small sheaves. The moulded notches let the belt bend around smaller sheaves, run cooler and carry more load than a wrapped belt in the same groove, so it is often chosen for blowers, air handlers, rooftop units, ventilation fans and compressors that run long hours. The oil- and heat-resistant compound suits mechanical rooms and plant floors. Longer lengths like this are typical on larger air handlers, rooftop units, condenser and cooling tower fans, and process blowers where the motor sits further from the driven sheave. Belts of the same size are made to run as a matched set, so the BX90 works on single-groove drives or in multiples on multi-groove sheaves. Before fitting the BX90, check the sheave grooves for wear and confirm pulley alignment, then tension the drive to the equipment manufacturer's specification. On multi-groove drives, replace the full set together. It is listed by RSL as SKU BX90-BES in the motor and fan parts belts category.
