Idler Bearings

Idler life is a function of many factors, such as belt speed, shell thickness, seals, and bearings. The idler load and rating of a bulk material handling belt conveyor system depend on the rating of the bearing. The table below covers standard-bearing dimensions used on typical conveyor idlers.
