Detailed Product Description

Steel-Sintered-Bronze-PTFE Composite Material - maintenance-free


No minimum on steel backed ptfe bushing & sliding Bearings. Metric Size or inch size, Custom Lubricating Parts Available. Types: PTFE Bushing, POM Bushes,Cast Bronze Bearings, Oil Impregnated Bearings, Plug Graphite Bearings, Vehicle Bushings, Wear Plate.

Material - Characteristics

 

Steel with porous sintered tin bronze layer, which is coated with PTFE as sliding layer.

  • DU self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions

  • Bushing material suitable for lubricated applications

  • Anti-friction bearing suitable for linear, oscillating and rotating movements

  • Approved to standard FAR 25.853 and FAR 25.855 - Federal Aviation Regulations – making it suitable for interior aircraft applications

Features


Suitable for dry running with a low coefficient of friction, low wear rate, good sliding characteristics, the transfer film created will protect the mating metal surface. Suitable for rotary and oscillating movement, high chemical resistance, lower absorption of water and reduced swelling. Also performs well with lubrication.

 

Structures


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. Low-carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.
