Belts – Ribbed belts

They have a small section and a large contact surface due to the multiple trapezoidal profile.

The efficiency is superior to the V-belts, the power / volume ratio (kW / cm3) of 1.7 and the maximum bending frequency of 100.

They are frequently used in the automotive industry but also in other industrial fields where the requirement of reduced radial space is important.

The symbolization is done by the number of ribs, which indicates the width of the belt, followed by two letters indicating the profile of the belt and the effective length (eg 10 PL-1270).
