These belts are used if several pulleys are located on one level and the direction of rotation of one or more driven pulleys is to be changed. The optibelt DK double sided V-belt is ideally suited for use in typical serpentine designs.
No special grooved pulleys are required for using optibelt DK double sided V-belts. Standard grooved pulleys with the appropriate profiles can be used. These belts are mainly used in agricultural machines and increasingly also in general engineering.
