Straight roller bearings
These polyolefin wheels feature straight roller bearings, which consist of a cage-type roller assembly and a split outer race. These bearings turn on hardened and ground spanner bushings which provide a long wearing precision inner race. Press fit combination metal retainer/thrust washers hold the bearings in place. Straight roller bearings have a high radial capacity, but minimal side thrusting load rating.
