Bronze-Based Bearing: SF-1B is of high safety factory, and is particularly appropriate for high temperature environment where no oil is effcient and where the machine must be under successive long period working condition.
This is widely used in steel metallurgy industry such as bushes for roller grooves of successive casting machinery. Cement grouting pumps and screw convery ers 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.
It can be applied in bridge bearing plate because of thicker inner surface layer to arrive 120M/MM2.

Technical:
Load capacity: 140N/mm2
Temperature: -195~+30...C
Speed limit: 5m/s
Friction coef(u): 0.03~0.18
PV LIMIT(Dry): 4.3N/mm2. M/s
PV LIMIT(Oil): 50N/mm2. M/s

Application:
1. PTFE and lead can protect the shaft, while the machine in operation.
2. It can be composed in steel housing, or fabricated into flanged bushes
Which result in function for montion both on flange and I. D.
3. It is widely used in steel metallurgy industry, such as bushes for foller
Grooves of successive casting machinery, cement grouting pumps and scrow conveyers of machine.
4. Bronze have good thermal conductivity, it'll divert heat while the machine operating.
5. It can be applied in the machine, working long time, which examine and repair is incapable, because the bronze can lubricate itself.
6. It is used in the feeble acid and alkali condition because of good anti-corrosion of bronze backing.
7. Good load capacity.
