SINOCONVE High Quality A Type A15 A16 A17 A18 A19 A20 A21 A28 Transmission Wrapped V-Belt
A-type transmission wrapped V-belts are designed for power transmission in industrial machinery and pulley drive systems. The wrapped construction combines a rubber body, polyester cord reinforcement and an outer polyester-cotton canvas to support stable pulley engagement, controlled elongation and durable operation.
The A15, A16, A17, A18, A19, A20, A21 and A28 length options should be selected according to the existing belt marking, pulley groove, finished length, transmitted load, speed, tension method and working environment. Share the drive information with our team so we can confirm the correct belt specification.
