Belts
Belts are used to transfer power, or revolutions from the driving to the driven pulley.
V-Belts
V-belts are the most common type of drive belt. They are wedge shaped. During operation, they allow slippage to occur.
Poly-V Belts
Poly-V belts belts are V-belts for transmissions with small pulley diameters, large gear ratios, high speeds and double-sided belt bending.
Timing Belts
Toothed belts enable synchronous transmission of revolutions without slipping. The speeds of the driving and driven pulleys are the same.
