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
