Description

About 4 Grooves 8V Sheave

Four 8V belts are the compact end of the 8V range: enough belt width for high torque, but a rim narrow enough to fit inside a guarded frame and light enough for one person to lift in the smaller sizes. This range covers 17 stock pitch diameters from 12.5 to 53 in with F, J and M bushings. 


The QD bushing system provides secure shaft mounting and easier installation compared with traditional fixed-bore pulleys. Due to their reliable performance and maintenance advantages, 8V QD sheaves are widely used in mining, aggregate, cement, steel, and heavy industrial machinery.

FAQs

What is the difference between the 4-groove and 5-groove 8V sheave?
One belt of capacity and roughly 20 percent more rim width. The pitch diameters available are the same, 12.5 to 53 in, so the two are interchangeable on the same shaft if the guard has clearance.
Can this sheave be used as a motor pulley?
Yes, it is used on both the motor and driven shafts. The limiting factor is the bushing bore against your shaft diameter, not the position in the drive.
