Self-lubricating steel backed 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.

If these material sections are used to create slide paths, they
have the following main functions:
1.Absorbing and transferring forces acting vertically to the
running surface
2.Fixing moving components to each other
3.Ensuring guidance accuracy for axial movements over the entire
service life
Strips are available in two material groups:
1.Material group P1 for maintenance-free, dry-running applications
2.Material group P2 for low-maintenance, lubricated applications
For the advantages of each group and help deciding which material
group is best for the relevant use, please refer to the information
provided in the section cylindrical bushes, flange liners and
thrust washers.
VSB-10 Steel + Bronze Powder + /Fibre Bushings
· Bushing material suitable for lubricated applications
· self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running
conditions
· Anti-friction bearing suitable for linear, oscillating and
rotating movements
Material is designed to operate without supplemental lubrication
and will perform excellent when lubrication is present. Low friction, low wear rate, good sliding characteristics and very
low absorption are a few of the features of this material. VSB-10 bushings will support rotary, linear and oscillating
motion.
Strusture
1. /Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the
rotating shaft. Minute partides of the 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 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.
