Industrial belts are used to transfer mechanical power. They include V-belts, round belts, timing belts, and flat belts. V-belts have tapered cross-sections that allow the grooves to grip the V-belt pulleys to transmit high torque and reduce slipping. Round belts are used in pulleys with a 60-degree V-groove. Timing belts have external teeth that interlock with the teeth of timing belt pulleys. They are either single-sided or double-sided. Flat belts are used with pulleys that have crowned surfaces to prevent them from slipping under heavy loads. They have largely been replaced by V-belts and timing belts.

  • Timing Belts

    Timing Belts (7321)

    Timing belts, also known as cogged or synchronous belts, have teeth that fit into a matching toothed sheave or pulley. When correctly tensioned, they have no slippage, run at constant speed, and are often used to transfer direct motion for indexing or timing purposes. They produce less noise than chains and sprockets and do not require lubrication. Timing belts require…
  • V-Belts

    V-Belts (3038)

    V-belts reduce slippage and alignment problems of other types of belts. They allow for the best service life through a good combination of traction, speed, and load. They are usually endless and the cross-section has a trapezoidal shape. The "V" shape of the belt rides in a groove of a sheave or pulley. The belt wedges into the groove more…
