Category: Metric Series

  1. The inner and outer rings are coated with molybdenum disulphide for reduced sliding friction.
  2. This spherical plain bearing has an outer ring groove and thru holes for relubrication.
  3. This spherical plain bearing has two crossed grooves on the load face of the outer ring to enhance the spreading of the grease lubrication.
  4. This spherical plain bearing must be properly lubricated with grease.
  5. 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.
