Material
Tin bronze + porous sintered copper powder layer + PTFE/inorganic filler (red)
Application features
Extremely low friction factor and very good lipophilicity
Suitable for linear, swing, and rotary motion
The bronze matrix has good anti-corrosion resistance and good heat conduction properties in a humid salt spray environment
Used in wind power, high-speed rail, outdoor lifting machinery, cement and screw pumping machines, etc.
