Metal-Polymer Plain Bearings Grease Lubricated Self-Lubricating Bearings
1. Product Description
Metal-Polymer Plain Bearings Grease Lubricated Self-Lubricating Bearings are sliding bearing made of three layers of self-lubricated bearing material, which is composed of high quality low-carbon steel plate or copper plate as the matrix, sintered porous spherical bronze powder in the middle, and friction surface rolling modified PTFE and firmly combined by high temperature plasticization.
2. Specification
| Load capacity | Static load | 250N/mm2 | Friction coef μ | 0.05~0.20 |
| Dymamic load | 140N/mm2 | Working temperature | -40℃~+110℃ | |
| Oscillating | 70N/mm2 | Themal conductivity | 4W/mk | |
| PV value limit | Oil lubrication | 22N/mm2.m/s | Speed limit (in oil) | 2m/s |
| Dry friction | 3N/mm2.m/s | Coefficient of linearexpansion | 11×10-6/K |
3. Application
Metal-Polymer Plain Bearings Grease Lubricated Self-Lubricating Bearings are widely used in hydraulic machinery,port machinery,pneumatic industries etc.
4. Advantages
It is suitable for use without lubricating oil, low friction resistance, wear resistance, long service life.Suitable for use in various forms of motion such as rotation, reciprocation and oscillation;It has stable low friction coefficient and excellent wear resistance under high load and low speed.Oil lubrication conditions for more effective use, in the middle, high speed field can show a high PV value.
