SKF's MRC HNCR ball bearings are designed for tough, corrosive applications

MRC brand HNCR deep groove ball bearings offer corrosion resistance to withstand harsh operating conditions. These bearings are manufactured from high nitrogen corrosion resistant steel (HNCR) to provide corrosion resistance, hardness, and fatigue life compared with standard 52100 or 440C stainless steel counterparts. In addition to HNCR rings, the bearings integrate ceramic balls, stainless steel cages, and stainless steel-backed rubber seals.

HNCR also exhibits greater "cleanliness" than 52100 and 440C steel with virtually no trace of sulfides, aluminates, silicates, or globular oxides. The lack of these non-metallic contaminants further contributes to longer bearing life. MRC HNCR deep groove ball bearings can be supplied in either open or closed designs and in a range of bore sizes.
