V-belts are often seen in belt pulleys. The specifications and models of belt pulleys in China are divided into a, B, C, D, e, O and other models and specifications, which are all determined according to the specifications of different back widths and heights of belt pulleys.

General purpose o a B C D E 3V 5V 8V, general thickened ax BX CX DX ex 3vx 5vx 8vx, narrow V-band SPZ spa SPB SPC, super strong narrow V-band XPA XPB XPC. Each model and specification of the triangle belt requires the cross-sectional specification of the triangle belt.

The cross section specification of type a triangle belt is: the total width of the top is 13mm, and the thickness is 8mm. The cross-sectional specification of B-type V-belt is: top width 17mm, thickness 10.5mm; The cross section specification of C-shaped triangle belt is: the total width of the top is 22mm, and the thickness is 13.5mm.

The total width of the top is 21.5mm, and the thickness is 19mm; The cross section specification of E-shaped V-belt is: the total width of the top is 38mm, and the thickness is 25.5mm. Matching specifications (width * height): O (10*6), a (12.5*9), B (16.5*11), C (22*14), D (21.5*19), e (38*25.5).
