What is V-belt Sheaves?
American Standard V-Belt Sheaves are widely used power transmission pulleys designed according to ANSI and RMA standards. These sheaves work together with V-belts to transfer power efficiently between rotating shafts in industrial machinery.
Available in AK, BK, 3V, 5V, 8V, and QD bushed and split taper configurations for a wide range of machinery and heavy-duty applications.
CTS supplies precision-machined cast iron V-belt sheaves designed for smooth operation, high transmission efficiency, and long service life. Our sheaves are widely used in pumps, compressors, HVAC equipment, crushers, conveyors, agricultural machinery, and other industrial drive systems.
American Standard Sheaves
Compared with European standard pulleys, American standard sheaves mainly use classical belt profiles such as A, B, and C sections, as well as narrow profiles including 3V, 5V, and 8V. They are commonly used in North American industrial markets and are highly valued for their durability, easy maintenance, and wide interchangeability.
CTS manufactures a complete range of American standard sheaves with various groove configurations, bore styles, and mounting systems to meet different industrial transmission requirements.

FAQ
What is the difference between 3V and 5V sheaves?
3V sheaves are designed for smaller, narrow V-belts and compact drive systems, while 5V sheaves are used for higher horsepower and heavier industrial loads.
Are your sheaves dynamically balanced?
Yes, many sheave models are dynamically balanced for smooth high-speed operation and reduced vibration.
Do you provide QD bushed sheaves?
Yes, we supply QD-bushed sheaves, split-taper sheaves, and other mounting styles according to customer requirements.
