David from CanadaOur company import the bronze gleitlager from viiplus china,viiplus professional team makes sure customs clearance is always smooth. They provide an accurate bronze bushing classification, handle all the paperwork,We have received the self-lubricating bronze bushings. They look well done and the high quality.
Valerie from CaliforniaWe import the bronze gleitlager from China to under the incoterm FOB shanghai, sometimes by Air. viiplus is a very good bronze gleitlager supplier, they are very professional and patient, after we inform the new order, they will manufacturer bronze gleitlager in time and give us the schedule , and then we just need to receive the bronze parts
Daisy From GermanyThe best surface finishes for Sleeve Bearing, tighter concentricity, and bronze bushings material uniformity. The good supplier of standard inch and metric sleeve bearings and bushings from china.

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?
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.

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.
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
