Oilless Bushing
Oilless Bushing

Material Structure:

1. PTFE/Pb mixture 0.01~0.03mm as sliding layer, provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming homogeneous oxide type solid lubricant film.

2. Porous bronze 0.2~0.3mm, provides Max. Thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE-lead mixture.

3. Low-carbon steel backing 0.7~2.3mm, provides fundamental structural support and gives exceptionally high load carrying capacity, excellent heat dissipation.

4. Tin-plating 0.005mm or copper-plating 0.008mm, provides good corrosion resistance.


1. Good wear and friction performance over a wide range of loads, speeds and temperature without oil

2. Also perform well with lubrication


Long life


1. Standard cylindrical bushing, flanged bush, thrust washers and strips are available.

2. Lead free type is also available.

3. All special designs are produced accordig to your requirement.


HJB01X DU bearing is widely used in lifting equipment, hydraulics and valves, pneumatic equipment, medical equipment, textile machinery, agriculture equipment, construction equipment, material handling equipment, packaging equipment, automotive field, scientific equipment, drying ovens, office equipment, etc.
