MRC Ultra corrosion-resistant sealed deep groove ball bearings
Helping to reduce unplanned downtime, maintenance costs and more, these bearing solutions provide a significant breakthrough in extending bearing life – along with the ultimate corrosion resistance.
Applications in extreme, harsh and highly corrosive environments
These innovative bearings are ideal for applications in freezing, abrasive, wet and corrosive environments. For example, MRC Ultra corrosion-resistant sealed deep groove ball bearings extended the life of an ice cream manufacturer’s hardening tunnel by up to 5 years, reducing maintenance time and costs.

Key features for food safety and corrosion resistance
- High nitrogen corrosion resistant stainless steel technology (HNCR) is used for the bearing inner and outer rings. Combined with ceramic balls, the corrosion resistance and fatigue life of these bearings is far superior to bearings made from 52100 and 440C stainless steels (Fig. 1). (See test in brochure link to the right.)
- The seals are made from synthetic rubber, coloured blue for optical detectability should any fragments enter the food stream, and complying with US Food and Drug Administration regulations (FDA)**
- High quality grease, suitable for typical food and beverage application conditions registered by NSF as category H1*
* Lubricant registered by NSF as category H1 (lubricant acceptable with incidental food contact for use in and around food processing areas). The NSF registration confirms it fulfils the requirements listed in the US Food and Drug Administrations guidelines under 21 CFR section 178.3570.
** FDA (CFR 21 section 177.2600 for ‘Rubber articles intended for repeated use’ for use in contact with aqueous and fatty foods)
More ice cream with less maintenance
An ice cream manufacturer was experiencing problems with standard steel bearings that were typically only lasting about one year in the hubs. See how SKF MRC Ultra corrosion-resistant sealed deep groove ball bearings increased the life cycle of the hardening tunnels.
