Stainless steel ball bearings refer to stainless steel radial ball bearings, especially stainless steel deep groove ball bearings. Generally, the balls and bearing rings are made of 400 series stainless steel, after heat treatment, the hardness can reach 58HRC. The retainers and seal ring frames are made of 304 stainless steel. Compared with ordinary ball bearings, stainless steel ball bearings not only have obvious advantages in terms of materials, but also have stricter technical and precision control. In the working process, this type of bearing has performances of stable operation, low noise and corrosion resistance. In the environment with salt water or other corrosion, stainless steel bearings are used to improve the bearing capacity and heat transfer effect. They are widely applied in fishing reels, shower room pulleys, food processing machinery, medical equipment, high-speed machine tools, water pumps, motors, textile printing machinery, and other machinery directly contact with acid and alkaline solutions. We can provide customers standard stainless steel deep groove ball bearings, including metric and inch sizes, and offer a one-stop sales service.
