Steel Shell Cast Bronze With Graphite Cylindrical Bushes Metric Shock Resistance
1. Product Description
Steel Shell Cast Bronze With Graphite Cylindrical Bushes Metric Shock Resistance is a kind of high strength and save material of self-lubricating bearings, compared with general inlaid copper alloy solid lubricated bearing, its product coat, with the low price with low carbon steel, the inner surface is 1 ~ 2 mm base copper alloy and copper alloy inlaid solid lubricating bearing the same, it's combined with the resistance of copper alloy and high mechanical strength properties of steel.
2. Specification
| Basic material | Steel+CuZn25A16Fe3Mn3 | Dynanic load | 150N/mm² |
| Base hardness | HB>70 | Friction Coef | <0.14 |
| Temperature Max | 400℃ | Speed limit |
dry 4m/s oil 10m/s |
3. Application
Steel Shell Cast Bronze With Graphite Cylindrical Bushes Metric Shock Resistance are widely applied in various moulds,injection machine ,port machinery ,engineering machinery ,metallurgical machinery etc.
4. Advantages
The bushes compare with pure bronze bearing,the cost is reduced obviously and the steel backing allowed to heat treatment to get high hardness,meanwhile the in layer can be remachined if necessary, the bronze layer can be casted on one or more layers to complex structure,this bushing has better mechanical load preformance compare with bronze material,especially the impact strength.
