This three layer composites for DX Boundary-lubricating bush and bearing include cold-rolled steel, sintered porous bronze powder layer, with improved polyoxymethylene (POM) surface. Regular pits for oil are made on surface, which owns unique properties of both mechanical strength and rigidity and excellent antifriction on boundary lubrication conditions. As the layer of polyester is thickness enough for secondary machining, it can be sized to fit in precisely.
Parameter:
1. Improved POM thickness: 0.24-0.3mm
2. Spherical bronze thickness: 0.25-0.30mm
3. Steel back thickness: 0.7-2.2mm
4. Plating Cu and Sn thickness: 0.003-0.008mm
5. Oil pits available
Advantages:
1. Excellence wear-resistance, low friction coefficient
2. Long service life
3. Good at low-speed with heavy load
4. Fine compliant and adaptive property
5. Damping shock absorption, low noise
6. Less maintenance
7. Less weight, small shape, and less volume
8. Electroplating for anti-corrosion layer
