Ribbed belts are classified according to DIN 7867. The following data is used for classification: number of ribs, profile designation, reference length, design.
Endless rubber ribbed belts with a PJ profile have the following dimensions: rib distance 2.34 mm, belt height 3.8 mm, backing height 1.1 mm. They are used for large transmission ratios, drives with fixed centre distances, high belt speeds and with small pulley diameters and reverse tensioning idlers.
The CONTI-V® MULTIRIB is an endless rubber ribbed belt, which conforms to DIN 7867. These rubber ribbed belts are primarily used with large transmission ratios, high belt speeds and small pulley diameters.
The belt consists of a polychloroprene belt base and top cover and a polyester cord tension member and is electrically conductive in accordance with ISO 1813.
The CONTI-V® MULTIRIB ELAST is an endless rubber ribbed belt, classified according to DIN 7867, which is used for drives with fixed centre distances without separate tensioning equipment. It consists of a polychloroprene belt base and top cover and a polyester cord tension member, and is electrically conductive in accordance with ISO 1813.
The Optibelt RB is an endless rubber ribbed belt, classified according to DIN 7867, which is predominantly used in cement mixers, small compressors, small tools and white goods.
It features a wear-resistant rubber compound belt base, a polychloroprene top cover and a polyester cord tension member. The Optibelt RB units the excellent flexibility of flat belts with the high performance of V-belts.
