non-oil lubrication or less lubrication. low maintenance, with better sbrasion resistance, low friction index and anti-aging.

                                    

                 Self-Lubricating Bearing

Roughly introduction:

Materials Base Support Materials: BronzeIntermediate Laye: Bronze(Bronze powder in sintering processing) Inner Sliding Layer: PTFE and Lead(Pb) ( or PTFE only)

> Structure

 1. PTFE/Pb mixture 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming an oxide type solid lubricant film. 2. Sintered bronze powder 0.20-0.35mm, provides Max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE-lead mixture. 3. Bronze backing, gives exceptionally high load carrying capacity, excellent heat dissipation. Have very good corrosion resistance.

		Continuous operation	1.8N/mm².m/s
Temp.Limit			-195°C~+280°C
Friction coefficient			0.05~0.20
Max.speed		Dry running	2m/s
		Hydrodynamic operation	>2m/s
Thermal conductivity			42w(m.k)-1
Coefficient of thermal expansion			11x10-6.K-1

Application Feature:

1).Working under oilless or minim oil state,maintenance free or just need a litter maintenance

2).Resis Abrasion,low coefficient of friction long operation life.

3).Operation in -195°C~+280°C. 4).Good mending,low-noise,non-pollution.

5).Thin-walled structure,light in weight,which can reduce the machine to small size.

6).Forming a transferred film during operation to protece,shafe and trouble free.

7).Low demand to the shafe even no surface hardness treatment,which lower the cost of the mating components.

8).No absorption to water/oil ,small coefficient of thermal emption,good thermal conductivity and size stability

9).The back of the steel strip can be plated with various metals,anti-corrosion

Maintenance It is a dry sliding bearing with PTFE sliding layer. Lubrication is therefore not necessary, but basically possible.
