High-Load Face-Mount Crossed-Roller Bearings

Fasten directly onto hollow shafts to support loads up to 60,000 lbs.

One-Way Locking Needle-Roller Bearing Clutches

One-Way Locking Needle-Roller Bearing Clutches

Needles roll forward, but lock to transmit torque when rotation reverses

Cylindrical Roller Bearings

Cylindrical Roller Bearings

Support heavy loads at high speeds

High-Load Crossed-Roller Bearings

High-Load Crossed-Roller Bearings
