Spherical Plain Bushings

The outer ring bore of our spherical plain bearing includes a concave spherical surface. The outside diameter of the inner ring, or ball, has a convex spherical surface. We match these two spherical diameters to offer the optimum combination of load capacity and bearing frictional torque. This attention to detail in both design and manufacturing makes NPB spherical plain bearings products of choice, best suited for applications requiring the transmissions of heavy loads under oscillatory as well as continuous rotational motions. They are also intended for applications requiring angular misalignment. Our bearing rings and balls are made of high strength bearing steel, heat treated to Hrc 58 minimum hardness for longevity of performance.

Spherical plain bearings are designed to provide rotational motion in omni-direction. There are primarily two types of spherical plain bearings, radial and angular contact. Spherical plain radial bearings offer high load carrying capability in primarily the radial direction. Spherical plain angular contact bearings are designed for high load carrying capability in mainly the thrust or axial direction.
