Spherical Bearings | Rod End Bearings | Ball Transfer Units
Spherical Bearings are consist of an inner ring with a sphere convex outside surface and a outer ring with concave inside surface. They are also called Spherical Plane Bearing, Spherical ball bushing bearings and Ball Bushings.
A Rod End Bearing is also called as heim joint or rose joint. It consists of a spherical bearing in an eye-shaped head of the rod end housing and used on the ends of control rods, steering links and tie rods. Rod Ends allow tie rods to perform a rotation in a precise and controlled manner.
To find a right ball transfer, there are 2 things we need to to conside, one is the load capacity, the other one is the fixing method.
