Porous Polymer Plain Bushings DIN European Standard PTFE Sleeve Bearings
1. Product Description
Porous Polymer Plain Bushings DIN European Standard PTFE Sleeve Bearings taking high-strength copper alloy as the base material, holes are distributed on the working face in proportion according to the working conditions and filled with the solid lubrication column,minute partidesof the PTFE layer and the sintered bronze material combine tocreate a solid lubricant film.
2. Specification

| 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) | 2.5m/s |
| Dry friction | 1.8N/mm2.m/s | Coefficient of linearexpansion | 11×10-6/K |
3. Application
Porous Polymer Plain Bushings DIN European Standard PTFE Sleeve Bearings are widely used in hydraulic cylinder,gear pump, motor etc.
4. Advantages
This type of boundary lubricated bearing is suitable for the low speed and heavy load, intermittent operation and swaying conditions wihich can not oil or not allowed to oil occasions;Simplify oil supply design, reduce maintenance and repair costs and time,it has good wear resistance, low friction coefficient, extend the service life of the product.
