Bearing options
Choose between two different bearing options for Omega wheels.
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 roller 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.
