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 PTFE 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.

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.
