- The inner and outer rings are coated with molybdenum disulphide for reduced sliding friction.
- This spherical plain bearing has an outer ring groove and thru holes for relubrication.
- This spherical plain bearing has two crossed grooves on the load face of the outer ring to enhance the spreading of the grease lubrication.
- This spherical plain bearing must be properly lubricated with grease.
- A single bearing can only accept axial loading in one direction. A pair of opposing bearings are required for radial loading and bi-direction axial loading.
