PTFE Sliding Bushing Bronze Backed, Bronze With PTFE – Metric

Metal-Polymer Composite Self-lubricating Bushing Material

The PTFE sliding bushings are suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, forming a transfer film can protect the mating metal surface, suitable for rotary and oscillating movement.

Sliding Bushing PTFE Material Structure
  • Bronze Back + Porous Bronze Sinter + PTFE + Lead

  1. 0.01 ~ 0.03mm PTFE / Pb blend provides an excellent initial transfer film that effectively coats the mating surface of the hub assembly, forming a solid oxide type lubricating film.
  2. Sintered bronze powder 0.20-0.35mm, provides max. thermal conductivity from the surface of the bushing also serves as a reservoir for the PTFE / lead mixture.
  3. The bronze base provides an extremely high load-bearing capacity, excellent heat dissipation. Very good corrosion resistance.
Maintenance-free

PROPERTIES
It is a maintenance-free material due to the PTFE sliding layer. Outstanding sliding and wear performance. High load capacity and very versatile bushing.Extended performance due to the bronze backing.
RANGE OF APPLICATION
hydraulic cylinders, cranes and construction machinery, all sorts of production machinery, pumps and medial devices
MAINTENANCE
It is maintenance-free with a PTFE sliding layer. It is not necessary to lubricate this material, but basically possible!
MOUNTING ADVISE
Housing Chamfer min. 1.5 mm x 15-45°, for easy bushing alignment
Shaft Chamfer 5 mm x 15°, for easy insertion of the shaft
We advises to use a force fitting mandrel for the installation of the bushing. It might be necessary to apply some grease on the outer surface of the bushing when press fitting it into the housing.
Gluing Adhesive should not contact the sliding surface!
