GE80ES Corrosion Resistance Radial Spherical Plain Bearings

Product Description

Joint bearing is a special structure of sliding bearing. It has the advantages of simple structure than the rolling bearing, which is mainly composed of an outer spherical surface of the inner ring and the outer ring has an inner spherical form, able to withstand greater load, according to the different type and structure, can bear radial load, axial load and radial, axial and the existence of joint load.

Spherical plain bearings have spherical contact surfaces which permit the inner ring to rotate freely in all directions within bearing and application design constraints. This gives them the capability to self-align, which means, for example, to adjust automatically to misalignment stemming from inaccurate machining, frame distortions from welding, or deformations of pin and frame due to static and dynamic forces. Such misalignment would generate considerable end loading and cause early failure of plain cylindrical sleeve bearings. Thus spherical plain bearings are thought to have their origin as replacement for plain cylindrical sleeve bearings or bushings and are still occasionally called ball bushings. Spherical plain bearings utilize inner & outer rings with spherical sliding surfaces, and can accommodate heavy radial loads & bi-directional axial loads at the same time. They are generally used for lower swing speed of movement (that is, angular motion), as sliding surface for the spherical shape can also be tilted at an angle within the movement (that is aligning movement).

1. The inner and outer rings are coated with molybdenum disulphide for reduced sliding friction.

2. These spherical plain bearings have a single fractured outer race.

3. This spherical plain bearing does not have grooves and thru holes.

4. This spherical plain bearing must be properly lubricated with grease.

Features of spherical plain bearing

1. Material: the inner and outer rings are bearing steel (GCr15).
2. Heat Treatment: the inner and outer rings are quenched and phosphating.
3. Structure: There is no oil groove and oil hole in the inner and outer ring.The outer ring has an axial slot.
4. Sliding surface: coated with MoS2 powder lubricant.
5. Performance Characteristic: It has the advantages of abrasion resistance, corrosion resistance,and self aligning . It applies to the machine which requires heavy radial load and axial load in a small-range direction.
