Self Lubricating Sealed Spherical Plain Inch Bearing
Self-Lubricating bearings (as shown in Figure 6) do not require grease or oil for lubrication. Instead, they utilize a liner system bonded to the inside diameter of the outer ring. The inner ring or ball is made of heat treated high strength steel and is chrome plated on the outside diameter. The chrome plating provides a smooth, hard surface to run against the liner system. These bearings are also manufactured with seals to help keep contamination out of the bearing. Self-Lubricating bearings are particularly well suited when the loading is in one direction. Single direction loading prevents grease or oil from flowing into the load zone of the bearing, while the liner system provides uniform lubrication in the load zone.
