A-BX78-AI Cogged Classical V-Belt (5/8" X 81")

One New Aftermarket Replacement BX78 Cogged Classical V-Belt for Agricultural, Industrial, and Lawn & Garden Equipment

This BX-section cogged classical V-belt delivers reliable power transmission across a wide range of agricultural, industrial, construction, and lawn & garden applications. The cogged (notched) underside design increases flexibility around smaller-diameter pulleys, reduces heat buildup from friction, and extends belt service life compared to standard wrapped V-belts. Raw edge sidewalls provide improved gripping contact with pulley grooves for reduced slippage and quieter operation. The pre-stretched polyester cord construction resists elongation and maintains consistent tension over the life of the belt.
