Four point contact bearings, also known as four point contact ball bearings, are mechanical components with significant radial load capacity. The main feature of this bearing is that it can withstand both axial and bi-directional loads simultaneously

The main components of a four point contact bearing include: inner ring, outer ring, ball and cage. They together form a whole. Between the inner and outer rings, each ball moves in its gap, forming a four point contact. The four point contact bearing has a high static load capacity and can withstand radial loads, bidirectional thrust loads, and overturning moments

Four point contact bearings also have high accuracy and uniform load distribution, and can withstand high speeds. This type of bearing is widely used in the waist, elbow, wrist and other parts of industrial robots. Especially in mechanical equipment such as high-speed machine tools and automotive transmissions, it has excellent performance. In addition, four point contact bearings also have advantages such as easy installation, reduced axial dimensions, and high precision

Overall, four point contact bearings are a high-performance and widely used mechanical component, widely used in various mechanical equipment
