Multi-layer Bearings POM Wrapped bearing with acetalplastic bushings
1. Product Description
Multi-layer Bearings POM Wrapped bearing with acetalplastic bushings consist of a steel back, sintered porous copper powder interlayer and a surface modified polyformaldehyde (POM) sliding layer to form a surface rolling oil storage pit, thus achieving good lubrication between friction pairs.
2. Specification
| Load capacity | Static load | 250N/mm2 | Friction coef μ | 0.03~0.20 |
| Dymamic load | 140N/mm2 | Working temperature | -195 ℃~+280℃ | |
| Oscillating | 60N/mm2 | Themal conductivity | 42W/mk | |
| PV value limit | Oil lubrication | 22N/mm2.m/s | Speed limit (in oil) | 2.0m/s |
| Dry friction | 2.0N/mm2.m/s | Coefficient of linearexpansion | 11×10-6/K |
3. Application
Multi-layer Bearings POM Wrapped bearing with acetalplastic bushings are widely used in crane,automotive chassis,agriculture machinery etc.
4. Advantages
It has good wear resistance and bearing capacity.The steel backing provides higher mechanical strength of the bushing. Suitable for grease or oil lubrication and all kinds of movement, good load capacity, robust and insensible to dirt.
