1/2" Poly Fractional Belts

Our polyester belts use special flexible high heat resistant synthetic rubber making them tough and extremely flexible. Pre-stretched polyester cording provides high tensile strength and minimal stretching. Adhesion compounds bond the tensile cords in position and to the cushion rubber.

Understanding the Replaces “A” Number, e.g, A26
A: The A stands for an “A” section v-belt. This is considered a “Classic” v-belt style that has a top width of 1/2” (13mm) and a thickness of 5/16” (8mm) // 26: 26” is the inside circumference of the belt. For A-section v-belts, the outside circumference is found by adding 2 inches to the inside length of the belt. Therefore, the outside circumference of the A26 belt is 28 inches (26+2)
