Bando BX53 Cogged V-belt Bx Section 56 in Ol

Product Description

The BANDO BX53 is a classic cogged V-belt in the BX section, designed for power transmission in HVAC, industrial, and mechanical drive applications. It measures 56.0 inches in outside length, 21/32 inch (0.66 inch) in width, and 13/32 inch (0.41 inch) in thickness, with a belt pitch of 54.8 inches. The cogged construction reduces bending resistance and heat buildup, which extends service life compared to a standard wrapped belt. Made from rubber, this belt is rated for heat resistance and oil resistance. Installation is handled by HVAC technicians, maintenance mechanics, and equipment service professionals.

The BX53 is suited for use on HVAC blower drives, fan assemblies, compressors, pump drives, and general-purpose machinery where a BX-section cogged belt is specified. The cogged profile allows it to run on smaller-diameter sheaves without excess heat generation, making it a practical fit for residential and light commercial HVAC air handler and rooftop unit blower systems. Verify sheave groove profile matches the BX section before installation.

Installation Notes

Disconnect and lock out all power to the equipment before removing or installing the belt. Adjust sheave spacing to achieve proper belt tension — do not pry the belt onto a sheave under tension, as this damages belt cords. Inspect sheave grooves for wear, misalignment, or debris before installing a replacement belt. HVAC technicians and mechanical service pros should follow equipment manufacturer tensioning guidelines and applicable ANSI or ARPM drive design recommendations.
