Ideal for heavy duty caster applications because their tapered faces will handle any combination of downward and side forces. Used in various swivel assemblies as well as in wheels. Two bearings are installed per wheel, one in each side of the hub, consisting of a cup (hardened and ground outer raceway) and cone (roller assembly). Spanner bushings are not employed since adjustment requires tightening caster legs against the bearing assembly. Tapered bearings extend overall hub length of the wheel itself by approximately 1⁄4”.
