A-B491-AI Classical V-Belt (5/8" X 494")

One New Aftermarket Replacement Classical V-Belt for Agricultural, Industrial, and Lawn & Garden Equipment

This B-section classical wrapped V-belt is a standard power transmission belt used across a wide range of agricultural, construction, lawn & garden, and industrial equipment. The B-section (also designated 5L) design features a 40-degree angle profile that wedges into the pulley groove for efficient torque transfer -- the greater the load, the greater the wedging action. Constructed with a polyester cord tensile member encased in an engineered rubber compound and wrapped with an oil- and heat-resistant outer fabric, this belt delivers reliable power transmission, resistance to wear and stretching, and long service life.
