Stainless Steel Ball Bearings
Stainless steel ball bearings are standardly manufactured from high-quality 440C stainless steel for optimal corrosion and abrasion resistance, while the cages and shields are made from 304-grade stainless steel. Stainless steel deep groove ball bearings are utilized in a broad spectrum of applications such as; food processing, beverage plants, dairy, sugar processing, pharmaceutical, chemical processing, rubber and plastic plants, pulp and paper mills, marine environments, car washes, refrigeration and freezer settings, agricultural machinery, wastewater treatment, and more!Our stainless steel ball bearings are available in both inch and metric sizes and can be supplied as an open configuration, with seals (RS) or shields (ZZ). Because of the material attributes of stainless steel, these ball bearings will have lower load capacities than their carbon steel counterparts. We also supply stainless steel ball bearings in 304 and 316 grades upon request. For additional information or to get a quote on stainless steel ball bearings, contact our customer support team, and we will be happy to assist you!
Metric Stainless Steel Ball Bearings
Note: all dimensions are in millimeters (mm), 2RS = sealed on both sides, ZZ= shielded on both sides.
