Sheaves and Pulleys

Sheaves and pulleys control speed ratios, torque transfer, and overall drive efficiency in belt-driven systems. In pumping units, mills, motors, and fan systems, proper sheave selection directly affects belt life, vibration, and power transmission quality.

KSIS provides sheaves and pulleys across a full range of profiles and sizes—classical and wedge V-belt sheaves, variable pitch designs, timing and synchronous belt pulleys, fractional horsepower sheaves, and idlers—along with the compatible bushings and hardware for a complete fit-up.

If your application requires a hard-to-locate diameter, groove type, or mounting configuration, KSIS can source the right solution and help ensure your drive system performs as intended.
