Steel bearings

Custom HNRC bearings are made from high nitrogen steel and offer high corrosion resistance and fatigue life.

Features & benefits

Nitrogen and high chromium offer stronger resistance than 440C stainless
Hardened and tempered HNCR provides hardness (58HRC) comparable to 52100 steel
HNCR steel yields fatigue life better than 51200
Available in custom-engineered sizes

Ceramic ball bearings

Full ceramic and ceramic hybrid ball bearings absorb heat, are extremely resilient, achieve higher speeds, and reduce overall weight in harsh environments.

Features & benefits

Ceramic silicon nitride balls are 10 times stronger than steel balls and hold surface finish longer
Smooth surface reduces friction between balls and races
35% less thermal expansion and 50% less thermal conductivity than steel balls
Eliminate scarring and run cooler due to less micro-weld adhesion
