High polymer bearing
The high polymer is widely used in the bearing for ships’ stern tube and rudder. It can be used for all kinds of vessels around the world. It is the main material for the bearings. The High Polymer Bearing material is a co-polymer high polymer material, with all generalities of sliding bearings, suitable for open and closed lubrication system can meet the needs of a variety of environment. The high polymer bearing is with high abrasion resistance, multi-purpose and stability. It brings remarkable economic benefits to ship owners and shipyards and brings great social benefits for marine bearing materials domestication.
Type: FWD High Polymer Bearing, AFT High Polymer Bearing, Water Lubrication Bearing, Oil Lubrication Bearing
