X Type Four Point Contact Ball Bearing

X Type Four Point Contact Ball Bearings Structural Analysis

The X-type four-point contact ball bearing features thin section inner and outer rings, significantly saving valuable installation space and effectively reducing equipment weight. Its core "X-type four-point contact" design creates four points of contact between the raceway and the steel balls, enabling the bearing to simultaneously withstand radial and bidirectional axial loads. This design significantly simplifies mechanical construction; typically, one X-type bearing can replace two traditional angular contact ball bearings, reducing the number of parts and assembly steps.
