POM Bushes Self Lubricating Plain Bearing Split Type Standard Size
1. Product Description
POM Bushes Self Lubricating Plain Bearing Split Type Standard Size is based on a composite material with 3 firmly bonded layers: steel as a base, spherical sintered bronze powder as an intermediate layer and modified POM as a coating layer.It is especially suitable for rotating and swaying motion under heavy load and low speed, as well as opening and closing under load, which is not easy to form fluid lubrication.
2. Specification
| Load capacity | Static load | 250N/mm2 | Friction coef μ | 0.05~0.20 |
| Dymamic load | 140N/mm2 | Working temperature | -40 ℃~+130℃ | |
| Oscillating | 60N/mm2 | Themal conductivity | 13W/mk | |
| PV value limit | Oil lubrication | 22N/mm2.m/s | Speed limit (in oil) | 2m/s |
| Dry friction | 2.5N/mm2.m/s | Coefficient of linearexpansion | 11×10-6/K |
3. Application
POM Bushes Self Lubricating Plain Bearing Split Type Standard Size is widely used in mining machinery,metallurgical machinery,rolling steel machinery etc.
4. Advantages
It is especially suitable for rotating and swaying motion under heavy load and low speed, as well as opening and closing under load, which is not easy to form fluid lubrication.Under the condition of boundary lubrication, it can be used for a long time without refueling and maintenance.The plastic layer on its surface can leave a certain amount of margin in the shaft sleeve forming process, and can be processed by itself after pressing into the hole, so as to achieve a better assembly size.
