Wrapped composite sliding bearing, copper/tin plating
Suitable for dry running with a low coefficient of friction
Low wear rate, good sliding performance
Suitable for rotary and oscilating movement
Higher chemical resistance, low absorption of water and reduced swelling.
Excellent sliding and wear behaviour.
Cylindrical and flanged bushing, thrust washer, strips.
Standard or non-standard, on demand!
DIN 1494/ ISO3547
HLDB-1D metal-polymer composite bushings are backed with copper-plated steel with porous bronze sintered on the steel and polymer(PTFE) imbedded into the bores of the bronze. By combining the metals and polymer together, it performs good capacity of anti-abraion and self-lubrication with lower friction coefficient. The steel back is plated with a erosion prevention layer. HLDB-1D improved the friction and much good wear resistance over the common HLDB-10 range under lubricated operation.
