Classical V-belt
Classical V-belt section is trapezoid, the whole circle without joint, triangle belt specifications are divided by the size of the back width (top width) and height (thickness), according to the size of different top width and height, divided into seven types, respectively, O type, A type, B type, C type, D type, E type, F type, each type of section width, top width, height are not the same.
