Anti Corrosion Boundary Lubricated Bearing 3 Firmly Bonded Layers Type
1. Product Description
Boundary Lubricated Bearing is based on a composite material with 3 firmly bonded layers: steel as backing.sintered porous bronze powder as interlayer and modified POM as lining layer.It has oil pocket for oil lubrication.It fits well for slow speed,heavy duty under normal temperature.
2. Specification
| Load capacity | Static load | 250N/mm2 | Friction coef μ | 0.05~0.25 |
| Dymamic load | 140N/mm2 | Working temperature | -40℃~+130℃ | |
| Oscillating | 60N/mm2 | Themal conductivity | 13W/mk | |
| PV value limit | Oil lubrication | 22N/mm2.m/s | Speed limit (in oil) | 2.5m/s |
| Dry friction | 2.8N/mm2.m/s | Coefficient of linearexpansion | 11×10-6/K |
3. Application
Anti Corrosion Boundary Lubricated Bearing 3 Firmly Bonded Layers Type are widely applied in auto chassis, forging machine,metallurgical and mining equipment,construction machinery, power station,strip rolling industries etc.
4. Advantages
This type of boundary lubricated bearing can be work even if it is without lubricant or under atrace of oil. It is of low friction, anti-corrosion and is of long life.It can save cost and prolong working life when replacing normal bronze bushings,It can lower frquenc of adding oil,simplify replacement process when it is used on rolling mill.
