Round-Belt Idler Pulleys
Nylon Plastic
These pulleys spin freely on built-in bearings to maintain tension for reduced wear and vibration. They are often used with belt tensioners (sold separately). Ball bearings are double sealed to keep dirt out. Nylon pulleys are lightweight and corrosion and abrasion resistant.
