Create a superior driving experience


In recent years, the requirement of automobile equipment operation has been increasing.Our lead-free bearing material, with enhanced performance, can meet the most stringent performance requirements, better than ball bearings (limited space and weight, high load and swing movement may cause damage).
Bearing has many advantages, creating superior driving performance:
· long service life, reliable and smooth operation
· high wear resistance
Self-lubricating,
· low friction coefficient, low loosening torque and no stick-slip phenomenon
· compatible with many standard oils and lubricants
· high precision and stable size

Our self-lubricating bearings advantages


· a wide range of efficient bearing materials and solutions to meet the most demanding application requirements.
· compact, lightweight solutions reduce fuel consumption and emissions.
· seat: seat adjuster and height adjustment mechanism.
· continuous innovation of technologically advanced products, systems and tools to maintain our leading position in high-performance bearing technology.
· our application specialists provide technical support and customer-specific bearing designs to provide comprehensive customer support.

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. 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.

The main factors affecting the life of self - lubricating bearings


1: load P: the greater the load, the shorter the service life of the bearing;Under no circumstances shall the maximum load exceed the theoretical maximum allowable load.
2: speed V: the higher the speed, the shorter the service life of the bearing;Under no circumstances shall the maximum sliding speed exceed the theoretical maximum allowable value.
3: PV value: the working life of the bearing depends on the PV value, that is, the product of the actual load P and the sliding speed V. The smaller PV value is, the longer the bearing life is.
4: temperature: the life of the bearing also depends on the temperature when the bearing is in use, the higher the temperature, the shorter the life of the bearing, so in the design and selection should try to consider the heat dissipation characteristics of the relevant parts.
5: surface roughness of the grinding parts: alloy steel or hard chromium plated shaft is used for the grinding parts. When the surface roughness Ra=0.4-0.63, the service life of the bearing can be significantly improved.
6: other factors such as bearing design, lubrication conditions, etc
