Belts – V-belts – Raw Edge V-Belts

From the construction point of view, they have the same components but, on the small surface of the trapezoid, they have transverse grooves, which lead to the increase of the belt elasticity when winding on pulleys, reduce the bending tension and increase the contact surface on the pulley. As a result of this construction, the maximum frequency of bending increases greatly, which leads to a significant improvement in reliability.

The symbolization is done by indicating the name of the trapezoid followed by the datum length Ld in mm or in inches.
