SAE 52100 steel inner and outer rings deliver consistent hardness, fatigue resistance, and predictable long-term performance.

Annealed set-screw ports and 120° screw spacing prevent inner-ring cracking, maintain ring roundness, and provide longer-lasting shaft retention.

Extended inner rings improve shaft contact and reduce inner-ring cocking to extend service life.

Steel retainers improve thermal and fatigue resistance compared to plastic alternatives.

An anti-rotation device prevents the bearing from spinning in the housing while allowing it to self-align.

An integrated flinger deflects debris and moisture away from the seal to extend service life in contaminated environments.

Standard contact seals retain lubricant and block common contaminants.

Optional L3 triple-lip seals increase sealing contact for stronger protection in severe contamination conditions.

Rigid cast iron housings provide stable support under load, vibration, and shock, with ductile iron available in select configurations for added strength.

Set screw, eccentric collar, and Tru-Loc concentric locking options accommodate different requirements for holding power, shaft protection, and installation efficiency.

Available with Lubrilife permanent lubrication for maximum contamination protection without relubrication.
