Product Description

 Metal-Polymer Anti-Friction Plain Bearings self-lubricating Bearings Cylindrical PTFE Concrete Pumps Stainless steel bushing,Bronze Graphite bushings, steel bush,DU bushing
 
Carbon Steel self-lubricating bearings used high quality low-carbon steel plate as base, sintered porous bronze as its interlayer and the Compound of PTFE or POM and Lead as its surface.
 

self-lubricating bearings, corrosion resistance, suitable for the conditions of daily maintenance is difficult to maintain the mining environment.

 


They have developed some outlets in self-lubricating bearings, anti-friction compounds and protective coatings.

 


This SAE standard is the standard to which the Company intends to qualify its self-lubricating bearings to be produced in China.

 

Such bearings are most widely applied as self-lubricating plastic bearings;

TYPICAL APPLICATIONS

Application Of Large Pump Guide Bearing

Bearings are often placed underwater pressure, for guiding the bearing lubrication oil or water, which must be subjected to a good guide bearing wear, lubrication is possible in the case, installed on the respective sealing and drainage water leaking parts, this device can be prevented from flowing into the mixing water pump bearing.

Concrete Pumps Plain Bearings

Pump wear parts are mainly drive shaft and bushing, passive gear center hole and shaft pin, pump shell lumen and gear, gear face and pump cover, etc.
The durability of water-lubricated guiding bearing for a pump depended on the wear resistance of bearing bush.
 

 

 

 

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.
