Self-aligning spherical roller bearing geometry maintains high load capacity while accommodating shaft deflection, frame movement, and mounting variation.

SAE 52100 steel inner and outer rings deliver consistent hardness and fatigue resistance under heavy load.

One-piece cast iron housings have a solid base that maintains bearing alignment during continuous-duty operation and resists deformation under heavy radial and shock loads.

Precision-machined foot ends support accurate installation and repeatable alignment when used with a guide rail.

PTFE labyrinth seals protect against moisture and contamination while maintaining performance in high-speed and high-temperature applications.

Grease purge and pressure relief valves support controlled relubrication and protect seals from over-pressurization.

A standard 1/8-27 NPT grease fitting supports manual or automatic lubrication systems.

Mild steel locking collars improve set screw grip and durability; larger bore sizes are available with dual-collar locking for added security.

Available in fixed and expansion configurations to properly locate the shaft while accommodating thermal growth and axial movement during operation.
