V-Belts

Synchronous Belts

All synchronous belts are identified in a similar manner, in either English or metric units. Belts are measured by:

1. Pitch: Distance in inches or millimeters between two adjacent tooth centers as measured on the belt pitch line.

2. Pitch Length: Total length (circumference) in inches or millimeters as measured along the pitch line. It is equal

5/8"

to the pitch multiplied by the number of teeth in the belt.

3/8"

7/8"

3. Width: Always shown as the last part of the size designation. Denotes width in inches or millimeters.

8mm widths include: 12mm, 21mm, 36mm, 62mm;

Combine cross section designation with Outside Circumference (O.C.) to the nearest whole number, plus a zero to determine

14mm widths include: 20mm, 37mm, 68mm, 90mm, 125mm

Belt Part Number. Example: 5/8" top width 5VX belt with 80" O.C. equals 5VX800 V-Belt. X designates molded notch construction.
