Spherical plain bearings are guidable mechanical components ready to be applied. The dimensions are unified and permit the transmission of both static and dynamic strength in conjunction with oscillating alignment, rotary and bouncing movements in several directions. The internal ring is provided with an external convex spherical surface while the external ring is equally spherical with a concave internal surface. They are available with sliding surfaces realized in a combination of steel on steel and in many other executions which do not require maintenance.
The rod ends consist of a body, also defined as housing, in the form of a head in which is permanently inserted, in the proper seat, a spherical plain bearing, with dimensional precision and in the shape of the internal and external diameter, which comply with the same DIN specifications for revolving bearings. Even the principal dimensions of the spherical plain bearings and the heads follow the DIN specifications, internationally recognized by ISO regulations. ISB® spherical plain bearings are constructed respecting the principal tolerances and dimensions for mounting indicated by the above mentioned regulations. Consequently, they are interchangeable with products from the main.
