Detail Information

About 4 Grooves 3V Sheave

A 4 Grooves 3V Sheave is a narrow V-belt sheave designed for use with 3V section belts. Compared with standard classical V-belt pulleys, 3V sheaves offer higher power transmission efficiency and better performance in compact drive systems.

The 4-groove configuration is commonly used in light- and medium-duty industrial applications where only one belt is required. Due to its compact structure and efficient transmission capability, the 3V pulley is widely used in North American industrial markets.

CTS manufactures cast-iron 3V sheaves to ANSI and RMA standards to ensure reliable belt compatibility and stable industrial performance.
