non-oil lubrication or less lubrication. low maintenance, with better sbrasion resistance, low friction index and anti-aging.
Self-Lubricating Bearing Standard Metric Size
Roughly introduction:
Materials
1. PTFE 2. Porous bronze sintere3. Steel backing4. Copper-plating/tin-plating
Note: Various materials are suitable for HLDB-10 Series products according to different working conditions ,such as bronze backing (HLDB-1B),stainless steel backing (HLDB-1S)…
> 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.

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.
