Belts - Grooved belts
They have a narrow section and a wide contact surface due to multiple trapezoidal profiles.
The efficiency is superior compared to trapezoidal belts, power/volume ratio (kW/cm3) is 1,7 and the maximum bending frequency is 100.
They are often used in automobile industry as well as in other industrial fields where low radial space requirement is mandatory.
Symbolization is made through number of picks, that indicate belt’s wideness, followed by two letters that indicate belt’s profile and actual length (ex. 10PL-1270).
