Self-Lubricating Multilayer Composite Bushing Carbon Steel Copper Powder POM
1. Product Description
Self-Lubricating Multilayer Composite Bushing Carbon Steel Copper Powder POM is backed with copper-plated steel with porous bronze sintered on the steel and polymers (POM+Pb) imbedded into the bores of the bronze. By combining the metals and the polymers together, the products are endowed with the lower friction coefficient and good capacity of anti-abrasion and self-lubrication.
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 | 4W/mk | |
| PV value limit | Oil lubrication | 22N/mm2.m/s | Speed limit (in oil) | 2.0m/s |
| Dry friction | 2.8N/mm2.m/s | Coefficient of linearexpansion | 11×10-6/K |
3. Application
Self-Lubricating Multilayer Composite Bushing Carbon Steel Copper Powder POM is widely used in printing machinery ,tobacco machinery,packing machinery etc.
4. Advantages
The products are endowed with the lower friction coefficient and good capacity of anti-abrasion and self-lubrication. Moreover, the steel back is plated with a erosion-prevention layer,much more fit for which are not allowed to use the lead and difficulty forming the oil film or need lubrication parts.
