RCB-2S marginal lubricating bushings
Introduction
It is made of high quality low-carbon steel, sintered porous bronze as its interlayer, with the compound of POM as its surface. And has good load capacity & wear-resistant. It's used in vehicle chassis, forming machine tools, steel metallurgical machinery, mineral mountain machinery, hydraulic industry and rolling steel industry, etc. It is without lead, can meet the requirements of environment protection. |

1.POM 0.3~0.5mm
2.Porous bronze 0.2~0.3mm
3.Steel backing 0.4~2.2mm
4.Copper plating 0.008mm |
RCB-2S is similar to foreign made DS bush, and may be operated without lubricant or under a trace of oil. It is of low friction, anticorrosion and is of long life. This is now applied in machines under oscillating motion and in open field or in corrosive environment such as hoisters, bulldogger, tower cranes, and printing or dyeing machines for textiles.
