Maintenance Free Self Lubricating Plain Bearing Composite Bearings
1. Product Description
Maintenance Free Self Lubricating Plain Bearing Composite Bearings PTFE mixture thickness 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film. Suitable for linear, oscillating and rotating movements.
2. Specification

| Dymamic load | 140 N/mm2 | Dry friction | 3.6 N/mm2.m/s | ||
| Oscillating | 60 N/mm2 | Friction coef μ | 0.03~0.20 | ||
| Speed limit | Oil lubrication | 5m/s | Working temperature | -195℃~+300℃ | |
| Dry friction | 2.5m/s | Thermal conductivity | 42 W/mk | ||
| Coefficient of linearexpansion | 11 10 -6/K | ||||
3. Application
Maintenance Free Self Lubricating Plain Bearing Composite Bearings are widely used in moulds,metallurgical machinery, agriculture machinery etc.
4. Advantages
This WHB series of self lubricating plain bearing has high load carrying capacity, excellent heat dissipation and with very good corrosion resistance.It is very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions.Easy to mend, silent, non-polluting.Thin, light wall, which can reduce the volume of the machine.Formation of a film transferred during operation to protect the shaft.Low demand to the shaft even no surface hardness treament which lower the cost of the mating components.
