Four-point contact ball bearings are a special type of rolling bearing with the following features:
High load capacity: The four-point contact design enables the bearing to simultaneously support both axial and radial loads, optimizing load distribution and enhancing load-carrying capacity and rigidity.
Long service life: This design reduces friction and energy consumption, thereby extending the bearing’s operational life.
Wide range of applications: Four-point contact ball bearings are widely used in critical components across industries such as automotive and aerospace, and are suitable for various applications including compressors, pumps, and retarders.
Future development: Future advancements will focus on new materials, precision manufacturing, and intelligent technologies, expanding their use into emerging fields such as new energy.

Our standard four-point contact bearings feature a one-piece inner ring, giving them an external appearance similar to deep groove ball bearings. However, the key difference lies in the internal geometry: the raceways are shaped with a gothic arch profile, enabling four distinct contact points between the balls and the rings. This design allows the bearing to effectively support combined axial and radial loads in both directions.
For applications requiring higher load capacity, we also offer an optional version with a split inner ring, enhancing performance under more demanding conditions.
