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. https://www.bronzelube.com/

PTFE Self Lubricating Plain Bearing,
FAR 25.853 Self Lubricating Plain Bearing,
Steel Backed du bush
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
|temperature range||-200 up to +280 °C|
|max. PV value|
|dry||3,6 MPa m/s|
|oil lubricated||10 MPa m/s|
|max. sliding velocity|
|oil lubricated||5 m/s|
|max. surface pressure||stat. 250 MPa - dyn. 140 MPa|
|thermal expansion||11 x 10-6 °C-1|
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.
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.

|with oil||μ = 0,02||up to 0,08|
For Bearing Design
according to DIN ISO 3547-1 (formerly DIN 1494)
Thermal expansion has to be taken into account at temperatures above 80 °C.
