What are Spherical Plain Bearings?
Spherical Plain Bearings, robust and self-aligning sliding bearings, excel in accommodating impact loads. With their high resistance to such loads, these bearings are ideally
suited for oscillating sections that operate under slow yet substantial loads.
Types of Spherical Plain Bearings
-
Radial Spherical Plain Bearings: Featuring an inner ring with a sphered convex outer diameter and an outer ring with a matching sphered concave inner surface.
-
Angular Contact Spherical Plain Bearings: spherical in shape and are oriented at an angle relative to the bearing axis
-
Thrust Spherical Plain Bearings: Designed with a convex spherical surface on the shaft washer and a matching concave spherical surface on the housing washer.
-
Rod Ends: Composed of a shank-integrated, eye-shaped head that serves as a housing for a spherical plain bearing.
