Features and Benefits

(1) The belt is an elastomer that can mitigate load impact and run smoothly without noise.

(2) Overload will cause the belt to slip on the wheel, thus playing the role of protecting the whole machine.

(3) The grooves of most American standard pulleys are suitable for several different belt types, and the belt design and application are relatively flexible.

(4) There are many types of American standard pulley grooves and taper bushings. Some pulleys and bushings are allowed to be installed on the front and back, which has become a solution for harsh conditions on different occasions.

(5) American standard pulleys and taper bushings can achieve precise balance control and perform well in transmission.
