Self-lubricating steel backed du bushing bearings combine the advantages of many conventional lubricated metal plain bearings - especially high load capacities and dimensional stiffness - with the design freedom of self-lubricating materials, including the ability to perform well beyond conventional lubricants.

Custom Solutions for Demanding Technical Requirements

We work closely with our customers to develop new self-lubricating bronze bushings solutions that are then added to our list of catalog bronze bushing products.

• Extremely swell-resistant

• Does not absorb water

 

Preferred areas of application

 

• Maintenance-free operation under dry-running conditions

• Rotating or oscillating movements

• Up to a velocity of 2 m/s

• Linear movements

• Temperature range -200 °C to 280 °C

If these material sections are used to create slide paths, they have the following main functions:

 

• Absorbing and transferring forces acting vertically to the running surface

• Fixing moving components to each other

• Ensuring guidance accuracy for axial movements over the entire service life

 

Strips are available in two material groups:

VSB-10 Steel + Bronze Powder + PTFE/Fibre(DU) Bushings

 
1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute partides of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.
 
2. Sintered bronze powder thickness 0.20*0.35mm,A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.

3. Low-carbon steel backing. Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
