V-Belts

V-belts are endless flexible drive belts with a trapezoidal section that wedges into matching pulley grooves. Friction at the angled sidewalls transfers torque between shafts, with classical and narrower wedge profiles covering many industrial fans, pumps, compressors, conveyors and agricultural drives.

Questions about v-belts

What should I send to identify v-belts?

Send belt profile, pitch or inside length, wrapped or cogged form, number of belts, pulley and drive data. Record the complete belt marking and measure the drive if markings are worn, since outside length is not always the catalogue length. A clear photograph, drawing or readable reference can resolve details that dimensions alone do not show.

How should I select v-belts?

Match profile and construction to pulley grooves, power, speeds, centre distance, shock, environment and matched-set needs. Confirm the mating parts and operating environment before ordering, since an apparently similar size can use a different profile, material or internal arrangement.
