3TB Gripbelt Sheaves with Split Taper Bushings

3TB series pulleys are manufactured for A, AX, AA, 4L, B, BX, BB, and 5L v-belts, ranging from 3.75" to 38.35" in diameter. Depending on the pulley size, they are made to use with P1 taper bushings or Q1 taper bushings, which we also stock. Most of our 3TB pulleys are manufactured from a high-strength grade 35 cast iron, are phosphate-coated, and are painted for anti-corrosion. All of them are balanced at the factory for smooth machinery operation.

Features and Benefits

I. The belt is an elastomer that can mitigate load impact and run smoothly without noiseII. Overload will cause the belt to slip on the wheel, thus playing the role of protecting the whole machineⅢ. The grooves of most American standard pulleys are suitable for several different belt types, and the belt design and application are relatively flexible.Ⅳ. 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.V. American standard pulleys and taper bushings can achieve precise balance control and perform well in transmission.
