Metal-Polymer Plain Bearings Grease Lubricated
VSB20 abroad (DX) boundary lubrication bearing with high quality low carbon steel or copper plate as substrate, the middle sintered porous spherical bronze powder, the friction surface rolling modified polyformaldehyde (POM and Pb), and through the high temperature solid combination as one of the three layers of plasticizing boundary lubrication bearing materials (also called prelubricated bearing material), the rolling and sliding bearing.
The material can provide better bearing capacity and wear resistance, friction surface with oil pits, in the presence of a small amount of lubrication medium, its performance is better than other sliding bearing materials.
The product is suitable for working under normal temperature and medium (heavy) load, low speed occasions, to replace the traditional copper sleeve, which reduces the cost and extends the service life.
SB-20 boundary lubricated bearings are divided into steel base and copper base
1. POM thickness 0.30~0.50 mm. It provides high wearresistance and low friction even with only minute volume oflubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2. Sintered bronze powder thickness 0.20-0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel.Setting the foundation of the bushings, the steel back provides exceptional stability,load carrying and heat dissipation characteristics.
