Straight Roller Bearings

Straight roller bearings 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.

Tapered Bearings

Tapered roller bearings are true precision bearings designed for the heaviest loads, and/or high-speed operation.  In addition to great radial capacity, they have a side thrust load rating of 60% to 90% of radial capacity rating.  The assembly consists of an outer race or cup and a tapered cone roller assembly held in position with closures.  Spacers are provided to tighten the caster legs against the bearing assembly.  Two bearings are installed per wheel.
