Mars B52 Classical Wrapped V-belt B Section 52 in

Product Description

The MARS B52 is a classical wrapped V-belt designed for power transmission in HVAC, refrigeration, and general mechanical drive applications. Manufactured under the Gates Hi-Power II line, it features a B-section profile with a top width of 0.66 inches and a thickness of 0.41 inches. The outside length is 52 inches. The classical wrapped construction provides consistent grip and flexibility across a wide operating temperature range of -30 to 140 degrees F. Licensed HVAC technicians and mechanical service pros rely on this belt type to maintain blower and fan drive systems in residential and light commercial equipment.

This belt is suited for B-section sheave drives found in air handling units, condensing units, and belt-drive blower assemblies. The B-section designation corresponds to a standardized cross-section, making it straightforward to source as a direct replacement during scheduled maintenance or emergency service calls. It fits single or multiple groove sheave configurations that accept the B-series profile.

Installation Notes

Installation is typically performed by licensed HVAC technicians or qualified mechanical service personnel. Disconnect and lock out all power to the unit before removing or installing belts.
