When referring to a bushing with dimensions of 25x28x25mm, it
typically means a self-lubricating plain bearing bush with an outer
diameter of 28mm, an inner diameter of 25mm, and a length or
thickness of 25mm. bushings, also known as oil-impregnated sintered
bronze bushings, are commonly used in applications where
lubrication is difficult or undesirable.
These bushings contain a porous bronze material that is impregnated
with a lubricating oil, which is gradually released during
operation to provide long-term lubrication and reduced wear. They
are suitable for high-speed, low-load applications and can be used
in a wide range of temperatures and environments.
If you are looking for an equivalent or replacement for a bushing
with these dimensions, it is important to ensure that the material,
lubrication properties, and dimensions match your specific
requirements. You may need to consult with a bearing supplier or
manufacturer to find a suitable equivalent or replacement product.

Oil-free lubricated bearings are rolled plain bearings with steel
back as a matrix, spherical bronze powder sintered in the middle, a
mixture of and lead on the surface. It has the characteristics of low friction coefficient, good wear resistance, corrosion resistance and oil-free lubrication. Using this product
can reduce the cost, reduce the mechanical volume, avoid the phenomenon
of shaft bite and reduce the mechanical noise, etc. The products have been widely used in the sliding parts of
various machinery, such as printing machines, elevators, textile
machines, tobacco machines, fitness machines, hydraulic trucks,
micromotors, solenoid valves, automobiles, motorcycles and
agricultural and forestry machinery.

CHARACTERISTICS
VSB-10 Self-Lubricating Multilayer Composite Bushing
- 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.
