Technical output: with independent independent transmission system overall research and development design capabilities, to provide technical support for the car factory.
The core design of the four point contact bal bearing lies in the use of a special "Gothic arch" raceway section, which allows a single steel ball to form two contact points with both the inner and outer raceways, thus exhibiting a four point contact state when subjected to load. This unique design allows a single set of bearings to efficiently withstand bidirectional axial loads as well as certain radial loads and overturning moments. Its function is equivalent to a pair of back-to-back combination angular contact ball bearings, but the structure is more compact and space saving
Widely used in key fields such as industial robots joints, CNC machine tool spindles, precision turntables, and large-scale wind power yaw and engineering machinery slewing supports.
