RCB-1B bronze-based bushings
Introduction
It's based on bronze alloy of a particular formulation with high density with sintered bronze layer as its interlayer, with the compound of mostly PTFE and other factors. As it is without lead, which makes the bearing lubricating condition cleaner, and in accordance with environmental request. |

1.PTFE 0.01~0.03mm
2.Porous bronze 0.2~0.3mm
3.Bronze backing 0.7~2.3mm |
Can meet the demanding criteria for long life and trouble-free performance with or without lubricant, of high safety factor even...
Same as the RCB-10 BUSHING, But especially for high chemical resistance request.
Steel metallurgy industry such as bushes for roller grooves of successive casting machines, cement grouting pumps and screw conveyers for cement, it can also be composed in steel housing or fabricated into flanged bushes which can move both in radial and in axial directions.
The bearings are particularly appropriate for high temperature environment where no oil is efficient and the machine must be under successive long period working condition.
