Idler Pulleys

SP Series Pulleys

The SP series pulleys below incorporate a precision, double shielded, lubricated single row ball bearing which is ABEC3 precision built to give all the accuracy needed to satisfy the load, speed, and life expectancy requirements of many applications now using more expensive ultra-precise bearings.
Please note that pulleys with extended inner races are more expensive than those without extensions.
