Round-Belt Idler Pulleys
Brass
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.
Brass pulleys are nonsparking and fit in extremely small spaces.
