DU Metal-Polymer Anti-Friction Plain Bearings
Bearing forms available in standard dimensions
The main functions of the DU Cylindrical Bush Bearing are:
Absorbing and transferring radical forces
Fixing moving components to each other
Ensuring guidance accuracy with radial and axial movements over the entire service life
The Features of the DU Flange Bush Bearing are:
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.
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
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.
