Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts, in particular to a stable stainless steel bearing. Background Art

[0002] Compared with ordinary bearings, stainless steel bearings not only have obvious advantages in material, but also have stricter control in process and precision than ordinary bearings. During the working process, stainless steel bearings work stably, have low noise, are corrosion-resistant, and are widely used.

[0003] The existing stainless steel bearings still have the following problems when in use: most of the stainless steel bearings adopt a single-stage matching rotating structure design. When the stainless steel bearings are used, after the accessories of the rotating assembly are connected and installed in the single-stage rotating structure, the rotation relies on a single rotating structure. When the rotating structure is damaged or jammed, the rotation will be stuck or stopped. Utility Model Content
