Self Lubricating Bushings

Product Description

Self-Lubricating Bushings 

Self-lubricating bushings (lubrication free bushings) are made up of one of four basic compositions:

• Strong Cast Bronze with Solid Lubricants
• Bronze Wrapped Bushings
• Bronze Powder with Steel Material
• Sintered Bronze
• 
  

Composite Self-Lubricating Bushings 

Self-lubricating bushings are made up of one of two basic compositions;

• PTFE-Based Metal-Polymer Materials
• Thermoplastic-Based Metal-Polymer Materials

Lubrication free bushings are used in applications where extreme agitation of parts and the force of friction to wear on parts. These self-lubricating bushings are able to withstand high temperatures and have high load-bearing tolerances.

Bronze Backed, Bronze With PTFE Series - Metric 

 These Bushings are made of bronze backed with bronze powder PTFE/Pb, are dry bushings, and have the following layers:

1. PTFE/Pb mixture 0.01-0.03mm, provides an excellent initial transfer film, which effectively coats the mating surface of the bushing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder 0.20-0.35mm, provides max. thermal conductivity away from the bushing surface, also serves as a reservoir for the PTFE-lead mixture.
3. Bronze backing, gives exceptionally high load carrying capacity, excellent heat dissipation. Have very good corrosion resistance.
4. 
   

Steel Bronze With PTFE/Fiber Series - Metric

 These Bushings are made of Steel bronze powder with PTFE/fiber, are dry bushings, and have the following layers:

1. PTFE polymer fibers mixture 0.01-0.03mm are lead-free providing an excellent initial transfer film, which effectively coats the mating surface of the bushing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder 0.20-0.35mm, providing maximum thermal conductivity away from the bushing 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 0.002mm, provides good corrosion resistance

Steel Shell With POM Plastic Liner - Inch And Metric

 These Bushings very similar to DX brand bushings in structure and are often substituted for DX bushings providing better value. Bushings are made of steel bronze powder with POM and have the following layers:

1. POM 0.3-0.50mm, has high wear resistance and low friction even only minute quantities of lubricant are supplied, this bushing surface carries a pattern of circular indents which should be filled with grease on assembly of the bushing.
2. Sintered bronze powder 0.20-0.35mm, provides max. thermal conductivity away from the bushing surface, also serves as a reservoir for the resin mixture.
3. Low-carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation.
4. Copper plating 0.002mm providing good corrosion resistance.
