It is suitable for boundary lubricating applications. It is recommended to lubricate the components with grease before assembling. The oil deposit can hold the lubricant with optimized matrix. Lubricating during the operation helps to prolong the bearing duration. The low friction coefficients, good wear resistance and reliable loading capacity of the bearing ensure a suitable application under low speed rotating and oscillating motion. CSB-20M is a material with POM thickness of 0.2-0.35mm without oil deposits on the surface, it is a machinable material after assembling.
1.POM thickness 0.30~0.50mm, provides good wear resistance. This bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2.Sintered bronze thickness 0.20-0.35mm, provides strong mechanical bond and excellent thermal conductivity.
3.Low-carbon steel, provides mechanical strength and thermal conductivity
The material has good wear resistance and it is suitable for middle to high load applications under the work conditions
of impact load and dusty environment. A pre-lubricating is necessary before assembling. The applications of this material include the commercial vehicle axel, brake system, suspension system, agricultural machinery, forest machinery and material handling machinery. It could be used to replace some traditional steel or bronze sleeves.
