  • HLDB-1P metal-polymer composite bushings also named as SF-1 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 provides good capacity of anti-abrasion and self-lubrication with lower friction coefficient. The steel back is plated with a erosion prevention layer.
