Rolling Bearing CA

Rolling bearings are precision mechanical components that convert the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction losses. Rolling bearings generally consist of four parts: inner ring, outer ring, rolling element, and retainer. The function of the inner ring is to match and rotate with the shaft; The function of the outer ring is to cooperate with the bearing seat and provide support; Rolling elements are evenly distributed between the inner and outer rings using a cage, and their shape, size, and quantity directly affect the performance and service life of rolling bearings; The cage can evenly distribute the rolling elements and guide them to rotate, providing lubrication.

Supporting the rotating shaft and its components, while maintaining the normal working position and rotational accuracy of the shaft, rolling bearings are easy to use and maintain, reliable in operation, good in starting performance, and have high load-bearing capacity at medium speeds. Compared with sliding bearings, rolling bearings have larger radial dimensions, poorer vibration reduction ability, lower lifespan at high speeds, and higher noise levels

Products DETAILS

Rolling Bearing CA


The structure of rolling bearings consists of parts
1. Outer ring - installed in the bearing seat hole and generally does not rotate
2. Inner ring - installed on the shaft neck and rotating with the shaft
3. Rolling element - the core component of rolling bearings
4. Cage - evenly separate the rolling elements to avoid friction
Features of rolling bearings:

 1. In the processing of specialized bearing parts, a large number of bearing specific equipment are used. If steel balls are processed using equipment such as ball mills and grinders. The characteristics of specialization are also reflected in the production of bearing parts, such as steel ball companies specializing in the production of steel balls and micro bearing factories specializing in the production of micro bearings.

 2. progressiveness Due to the requirements of mass production of bearings, it is possible to use advanced machine tools, tooling and processes. Such as CNC machine tools, three jaw floating chucks, and protective atmosphere heat treatment.

3.The specialization of automated bearing production provides conditions for its production automation. Fully automatic, semi-automatic specialized and non specialized machine tools are widely used in production, and automatic production lines are gradually being promoted and applied. Such as automatic heat treatment lines and assembly lines.
