Dry Sliding Glacier Split Bush Bearings DU

A range of PTFE lined wrapped bearings suitable for dry running, low friction, low wear applications. These wrapped bearings have excellent sliding characteristics forming a transfer film that can protect the mating metal surface.

PTFE lined wrapped bearings have been developed for high duty, oil lubricate applications. Such applications include, but are not limited to:

 

  • Automotive suspension struts
  • Shock absorbers
  • Hydraulic cylinders
  • Gear pumps and motors
  • Axial and radial piston pumps and motors

 

We are able to offer PTFE lined wrapped bearings in metric plain, imperial plain, metric flanged, metric washers, imperial washers, metric strip and imperial strip.

 Structure

 

  • A lead-free polymer fibre mixture provides an initial transfer film which effectively coats the mating surface of the bearing assembly, forming an oxide-type solid lubricant film

  • Sintered bronze powder provides maximum thermal conductivity away from the bearing surface and also serves as a reservoir for the PTFE mixture

  • Steel backing provides the high load carrying capacity which provides the wrapped bearings with outstanding heat dissipation

  • The copper/tin plating provides excellent corrosion resistance

  • These are versatile and extremely durable wrapped bearings and can be used in many applications. .
