POM Self Lubricating Plain Bearing Bronze Meatl Polymer Bearings Inch
1. Product Description
POM Self Lubricating Plain Bearing Bronze Meatl Polymer Bearings Inch Consist of a steel backing and a porous bronze intermediate layer and overlaid with modified polymers ( POM ).Indents on the surface of the polymer are designed for better distribution of the lubrication (oil or grease) between the bearing and themating material. The steel back provides the bush with higher mechanical strength and load capacity. Moreover, the steel backingis plated with a corrosion protection layer.
2. Specification
| Load capacity | Static load | 250N/mm2 | Friction coef μ | 0.05~0.25 |
| Dymamic load | 140N/mm2 | Working temperature | -40 ℃~+130℃ | |
| Oscillating | 70N/mm2 | Themal conductivity | 13W/mk | |
| PV value limit | Oil lubrication | 50N/mm2.m/s | Speed limit (in oil) | 2.5m/s |
| Dry friction | 2.5N/mm2.m/s | Coefficient of linearexpansion | 12×10-6/K |
3. Application
POM Self Lubricating Plain Bearing Bronze Meatl Polymer Bearings Inch are widely used in automobile ,crane,printing machinery etc.
4. Advantages
The bearing is Lead-free, environmentally friendly and acid polymethylaldehyde with high wear resistance. It is necessary to assemble with oil storage pit when the bearing surface is arranged regularly with grease, especially suitable for high load under the low speed of rotation, swing movement and often under load negative, opening and closing and less prone to forming fluid lubrication parts, under the condition of boundary lubrication, can use for a long time without refueling and maintenance, and in the process of gas can be used to more prolong the service life of bearing.
