DU Thrust Bearing Equivalent, GARLOCK washer Replacement manufacture parts, PTFE WASHER, SELF-LUBRICATING THRUST

DU-W thrust bearing & washer, Composite dry sliding bearings are primarily used for sliding bearing arrangements.

What is DU composite bearing?

Composite dry sliding bearings are primarily used for bearing arrangements where heavy loads have to be supported and where rotational or oscillating movements are relatively slow.

Where to use DU composite bearing?

Because of their good sliding properties and compact design, these plain bearings are particularly suitable for bearing arrangements where:

Maintenance-free operation is a prerequisite

There is a risk of lubricant starvation

Lubricants cannot be used or are forbidden

Space is limited.

Why choose du composite bearing?

Maintenance-free operation
No lubrication required (PTFE composite)
Initial lubrication required (POM composite)
Minimum wall thickness, minimum space requirements
Accommodation of heavy loads
Wide range of temperatures
Good sliding properties
Virtually no stick-slip
High wear resistance
Less sensitive to edge loading (POM composite)
No machining required.

Operating Performance

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.

Characteristics

• 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
