OOB-40 Steel + Bronze Powder + PTEE/Fibre Metal-Polymer Composite Bearings

The OOB-40 DP4 BUSHING improved the friction and much good wear resistance over the common OOB-10 range under lubricated operation, for dry running, low coefficient of friction, lower wear, good sliding characteristicCabin Door Hinge, Control Lever, Pedal &SeatPivots& bushingWiper Arms &Mechanism bushingThe oilless self-lubricating bearing is a composite bearing that consists of steel backing and wear-resistant porous materials. The special wear-resistant layer is formed by sintering the copper alloy powder and graphite-based solid lubricant dispersed on a metal base at high temperature. It has gone through special oil-containing treatment. A solid lubricant is uniformly distributed inside an alloy layer, so it can form a solid lubricant film at the beginning of sliding. With low shear strength, the film can be firmly adhered to the surface of the oilless self-lubricating bearing without cracking under ultra high static load. Therefore, the phenomenon of crawling will not occur under microscopic movement. The metal base provides ultra high mechanical strength and dimensional stability, so as to obtain distinguished friction and wear characteristics.1. Uniform dispersion of solid lubricant allows the oilless self-lubricating bearing to be used under friction condition from any direction. Also, superb performance of fretting wear resistance is provided.2. As a kind of engineering machinery bearing, this product can be used without oil.3. High load, excellent wear resistance, and unexceptionable speed characteristic 4. We can supply standard goods and different specifications of plates used for secondary processing.Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surfaces, suitable for rotating and oscillating movement, high chemical resistance, low absorption of water and swelling. TheOB-40 improved the friction and wear resistance over the common OOB-50 range under lubricated operation.
