The MARS B102 is a classical V-belt designed for heavy-duty conventional belt drive applications. With an outside length of 105 inches, a top width of 21/32 inches, and a thickness of 13/32 inches, this B-section belt is built to fit a wide range of industrial and HVAC equipment. Classical V-belts are one of the most common power transmission components found in air handling units, blowers, compressors, fans, and pumps. HVAC technicians, mechanical contractors, and maintenance professionals rely on B-section V-belts to keep rotating equipment running efficiently. The B102 fits drives that require a standard B-section belt with a 105-inch outside circumference. Classical V-belts transfer rotational power from a motor pulley to a driven component such as a blower wheel or condenser fan. Proper belt sizing is critical for maintaining correct tension, reducing slippage, and extending the service life of both the belt and the sheaves. A worn or improperly sized belt can cause vibration, reduced airflow, increased energy consumption, and premature motor failure. The MARS B102 is manufactured in the United States and meets recognized standards for classical V-belt dimensions and performance. Its B-section profile fits standard B-groove sheaves and variable-speed drives designed for this section size. This belt is a practical, reliable replacement choice for maintenance teams servicing rooftop units, air handlers, exhaust fans, and a wide range of industrial belt-driven equipment. Keeping a proper inventory of correctly sized V-belts reduces equipment downtime and simplifies preventive maintenance scheduling on commercial and industrial HVAC systems.
The MARS B102 classical V-belt delivers dependable power transmission in heavy-duty belt drive applications. Its standard B-section sizing makes it a direct replacement for a wide variety of HVAC, industrial, and commercial equipment drives.
