Detail Information

About 2 Groove BK Sheave

A BK-2 Sheave is a double-groove classical V-belt sheave designed for use with B-section belts. Compared with BK-1 sheaves, the dual groove structure allows higher horsepower transmission and improved belt stability for industrial equipment operating under heavier load conditions.


BK-2 sheaves are commonly used in compressors, conveyors, agricultural machinery, and industrial processing systems where reliable multi-belt transmission is required.


The wider B-section belt profile provides improved torque transmission and better durability compared with smaller A-section belt systems.
