VSB-10 Anti Friction Hydraulic Pumps Steel Polymer Plain Bearings
Dry Sliding Bearings manufactures a complete range of Bushing Bearings and Cast Bronze Bearings Materials all of which are made to the highest standards to optimize your products performance.Hardened Steel Bushings Plain Sleeve Bearing Garlock Bearing Die & Mold Bushes
The SELF-LUBRCIATING BEARINGS of Technology, a range of PLAIN BEARINGS products that has gained an excellent reputation for reliability and performance.
As CHINA MANUFACTURER in the field of STEEL PTFE SLEEVE BUSHING technology, VIIPLUS Oilless BEARINGS supplies
Flanged Bushing Carbon Steel/Stainless Seel PTFE Bush
DU bushing model MB5020-65FDU
tri-layer maintanence-free bushing have a base of lower carbon steel, onto which a porous bronze layer is sintered. PTFE mixtures are impregnated into the intersice of this bronze layer after rolling process completed. it has good physical & mechanical properties, also has certainly chemical properties. It is suitable for rotary, oscillating movement with performance of self-lub. Anti-wear, lower firction, lower noise.
1. Self-lubraiting Layer PTFE Mixture 0.01-0.03mm. After rolling process completed, PTFE mixtures are filled in intersice of bronze layer. Under normal operation, Part of PTFE mixture on top layer will be removed and transferred on the mating surface, forms a physically lubricating film, which will reduced the firction. and protect the mating shaft.
2. Porous Bronze layer; The layer provides bonded strength of Self-Lubricating Layer.
3. Steel Backing The layer provides load & thermal conductivity
4. Copper / Tin layer

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.
