JDB-3Steel And Copper Inlaid Bearing, steel back sintered with CuSn6Zn6Pb3 powder as a Lining, then solid lubricant is embedded evenly in it. It is of cost effective and higher crash strength comparing with JDB-2 type, its ends can even be welded with machine part and assemble together.
It is suitable for metallurgy machine, construction machine and where oil is hard to be employed.
| Using high-density bronze roll forming or spherical oil pockets, oil hole special internal surface to reduce the wear and tear to extend the use of time and good anti-corrosion function. | ![]() |
