Multi-ribbed belts
¡î Features: Multi-ribbed belts incorporate the benefits of flat transmission belts and banded V-belts, with small bending stress and centrifugal stress loss, high transmission efficiency. They apply to multiple shaft large power high-speed systems such as automotive engines.
¡î Marking: Multi-ribbed belts are divided into industrial multi-ribbed belts with PH,PJ,PL and PM models and automotive multi-ribbed belts of the PK model only.

Note £º The value of wedge distance and belt height is for reference only. Accumulated error of wedge distance is an important parameter, but it is influenced by working tension of the belt and elastic modulus. Back to Contents
