Product Description

Heavy Duty Bearings Bronze Backed PTFE Plain Bearing

Bronze base bearing self-lubricating bearing tin bronze, is based on tin bronze as the matrix, the middle sintered bronze spherical powder, surface rolling PTEE and high temperature resistant filler material.

 

The product in a special recipe of high density copper alloy substrate, sintered porous bronze layer. Surface rolling a mixture of PTFE and Pb. It can provide good self-lubricating, wear resistance, low friction, such as performance, give full play to the advantages of metal and multi-element polymer. Products used in the industries of metallurgy, continuous casting and rolling mill, cement machinery, screw conveyor and so on.

TYPICAL APPLICATIONS

  • Mining & quarrying

  • Heavy construction

  • Motorsport

  • Offshore oil & gas

  • Marine

Bronze + Bronze Powder + PTFE/Fibre(DU-B)

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

CHARACTERISTICS

 

 

Heavy duty bearings for applications that other bearings can't handle!

 

VSB-11 Bronze Backed PTFE Plain Bearing
· 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.
