Compared with ordinary bearings, stainless steel bearings not only have obvious advantages in materials, but also are more strict in technology and precision control than ordinary bearings, and have stronger rust and corrosion resistance.  With propriate dust cover and grease , they can be used in the environment of -60 ℃ ~ +300 ℃. Stainless steel bearings work stably during operation, with low noise and corrosion resistance. They are widely used in medical equipment, pharmaceutical machinery, low-temperature engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinery, etc.
