RCB-650 Solid Lubricant Embedded Bushings with graphite(DIN ISO 4379)
RCB650(C86300,CuZn24Al6Fe3Mn4,SAE430B)is based on bronze alloy with graphite,called graphite bushing. Basically general-purpose products, suitable for various circumstances Including high or low load,high or low temperature, with oil or oiless lubrication, or even In the water. With it's matrix made of high strength brass, It's hardness doubles than normal bronze bushings and the wear performance improves in large degree, so it is applicable for continue pitching machine, converors of metallurgy industry. It could also be used in plastic injection machines, in the automatic switch of high-tension electricity, in the luffing and surporting parts of construction machines, hydraulic gate supporter, pulley, drive wheels of water control project, and also for drying tunnel of paper machines, auto die, sliding parts for ships unmooring etc. The size is like SOB,SPB,WQZ,WQZD, JDB series. And we call boccole-autolubrificanti,bronzo graphite,Elementi di guida in Bronzo/grafite,We can offer bronze plates with graphite, bronze bushing with graphite, bronze washer with graphite, flange bronze bushing with graphite.
