Retainer bearing made copper alloy, hard alloy and POM colophony as holding frame, the surface was processed some well-regulated holes, and embed the rolling steel balls in the holes, orifice used technics of oil groove circle locked ball.

SF-1 self-lubricating metal composite materials to high-quality low-carbon steel substrate, sintered porous spherical copper powder layer, the surface rolled to the PTFE-based material as a wear-resistant lubricating the bearing layer.

JF-800/720/700/20/930 Bimetallic self-lubricating bearing used high quality low-carbon steel plate as base, sintered porous bronze as its surface, suitable for rotatory oscillating, reciprocating movements on the conditions of high load.

FB090 Bronze wrapped bushing, specially formulated high-density copper alloy strip base body surface may be requested by the user or hemispherical rolling diamond oil hole, oil sump.

JDB Solid- lubricant inlaid bearing use high grade metal alloys as their base material, inlaid graphite and grease during the process of friction, it will release solidlubricant and lubricant oil automatically.
