Product Description

THIN-WALLED SPLIT SEAM STEEL BACKING

JOURNAL BEARINGS | Self-Lubricating Bearings

Plain Bearings and Sleeve Bearings Metal-Polymer Low Friction Boccole DP4 CYLINDRICAL RED PTFE | VSB-40

 

VIIPLUS from China's main advantage products lead-free self-lubricating bearings. The U.S. 's GGB, Japan's OILES and DAIDO are the world's top three makers of self-lubricated bearings, with strong positions in aerospace, automotive and transportation.

VIIPLUS from China is located in jiashan county, zhejiang province, which is the national production base of self-lubricating bearings.

 

CHARACTERISTICS

Metal-Polymer Low Friction Plain Bearings


Steel + Bronze Powder + PTFE/Fibre(DP4)

 

Self Lubricating Bearings Low-Carbon Steel + Porous Bronze + Red PTFE

 

 

 

 


VSB-40 low friction bushings offer good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Very good performance in lubricated applications
· Good performance in greased applications
· Suitable for linear, oscillating and rotating movements
 
Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surfaces, suitable for rotating and oscillating movement, high chemical resistance, low absorption of water and swelling. The VSV-40 improved the friction and much good wear resistance over the common CSB-10 range under lubricated operation.

 

 

STRUSTURE

 

1. PTFE/Polymer fibres mixture thickness 0.01~0.03mm. Lead-free bearing layer provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE mixture.
3. Steel backing, provides high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.
