Product Description

SF-1D bronze base bearing ptfe metallurgical and steel industry cement grouting pump and spiral conveyor bush | VSB-11
 
Bronze + Bronze Powder + PTFE/Fibre(DU-B)

Dry Maintenance Free Bronze Base DU-B Self Lubricating Bush SF-1B

CHARACTERISTICS


 

 

· VSB-11

 

 

Sf-1b bronze base bearing is based on tin bronze, intermediate sintered bronze ball powder, surface rolling PTEE and high temperature filling material.

It has a high safety factor, especially in places where continuous work cannot be stopped and high temperatures cannot be refuelled. At present, it is widely used in metallurgical and steel industry, continuous casting billet rolling road, high temperature furnace front equipment, cement grouting pump and spiral conveyor. It can be a combination of the outer wave combination, and can also be made to turn the edge, to reach the end face, the inner hole and the effect of friction.

The rolling part of the bridge supports the replacement of the pure PTFE board with the products of sf-1b wear-resistant layer. Meet the requirements of 130N/mm squared.

 

· Very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions

· Suitable for lubricated applications

· Suitable for linear, oscillating and rotating movements

· Bronze back offers improved corrosion resistance in humid/saline environments

· Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surface, suitable for rotary and oscillating movement. Very high chemical resistance, low absorption of water and swelling, also performs very good lubrication feature, the bronze backing provides the improved corrosion resistance comparing with VSB-10.

 

STRUSTURE


 

1. PTFE/fibre mixture thickness 0.01~0.03mm, 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/Fibre mixture.
3. Bronze backing, provides exceptionally high load carrying capacity, excellent heat dissipation and very good corrosion resistance.
