MRC* high nitrogen corrosion resistant (HNCR) bearing technology
Enables you to achieve a breakthrough in bearing life with ultimate corrosion resistance.
Extreme corrosion resistance. The combined presence of nitrogen and high chromium in HNCR steel, delivers unprecedented corrosion resistance. Based on a naval corrosion test method, HNCR bearings exhibited zero signs of corrosion after a year-long salt bath immersion.
Hardness and fatigue life. HNCR is a martensitic through-hardened steel, capable of being case (or induction) hardened. Based on the rolling contact fatigue test method, HNCR bearings deliver two to three times the fatigue life of standard stainless steel.
