Rubber V-belts

Rubber V-belts are used in belt drives and have a trapezoidal cross-section, thanks to which the friction between the edges of the belt is significantly greater than with a flat surface.

Rubber V-belts are manufactured in endless lengths and feature a polyester tension cord. The use of V-belts permits the transmission of significantly higher torques than with flat belts – yet both have the same space requirements. Different types of V-belts are used in practice.

Classic V-belts are wrapped as standard in a fabric that prevents them from abrasion and are produced in the profiles 5, 6, 8, 10, 13, 17, 20, 22, 25, 32 and 40.

Narrow V-belts are also wrapped but are characterised by improved power transmission and are manufactured in the profiles SPZ, SPA, SPB and SPC.
