Polyurethane Covered Belt Pulley

Covered Belt Pulley alignment is important to flat belts. Belt tracking is improved by crowning at least one pulley, usually the larger one. Flat belts are forgiving of misalignment; however, proper alignment improves belt life. Different flat belt surface patterns serve various transmission requirements. In high-horsepower applications and outdoor installations, longitudinal grooves in the belt surface reduce the air cushion flat belts generate. The air cushion reduces friction between the pulley and belt. The grooves nearly eliminate the effects of dirt, dust, oil, and grease and help reduce the noise level.
