Understanding the Part Number
C – The C stands for a “C” section v-belt. This is considered a “Classic” v-belt style that has a top width of 21/32 (0.656) inches, but is commonly referred to as a 5/8 (0.625) inch belt. The thickness of the belt is 13/32 (0.406) inches.
53– 53 inches is the inside circumference of the belt. For C-section v-belts, the outside circumference is found by adding 4 inches to the inside length of the belt. So, the outside circumference of the C53 belt is 57 inches (53+4).
