Spherical Plain Bearings 2

Its basic structure consists of four parts:
- **Inner ring**: The inner hole is a cylindrical surface or a conical surface, which matches the shaft diameter and moves with the shaft. The outer surface is a spherical surface, which is the key contact surface for load transmission;
- **Outer ring**: The outer circle adapts to the bearing seat, the inner surface is spherical, and forms a sliding contact pair with the spherical surface of the inner ring to undertake the load transmission task;
- **Sliding contact pair**: The mating area of the inner and outer ring spherical surfaces is usually quenched, phosphated, etc. to improve wear resistance, or inlaid with self-lubricating materials to reduce friction;
- **Sealing device**: Some models are equipped with rubber sealing rings or dust-proof covers to prevent the intrusion of impurities and grease leakage, and are suitable for working conditions with high dust and humidity.Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
