|
Steel bronze powder with PTFE/ fibre dry bearings PTFE, polymere fibres mixture 0.01~0.03mm, lead-free provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming an oxide type solid lubricant film.
 Sintered bronze powder 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE mixture.
 Steel backing, provides high load carrying capacity, excellent heat dissipation.
 Copper/Tin plating 0.002mm, provides good corrosion resistance.
|
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. High chemical resistance, low absorption of water and swelling.
The -40 has reduced friction and better wear resistance over the common -50 under lubricated operation. |

Typical Application
|
|||||||||||||||||||||||||||||||||||||
|
Developed for heavy duty, oil lubricated, hydraulic applications... Automotive suspension struts, shock absorbers guide bushing, hydraulic cylinders, gear pumps, motors, axial piston pumps and in the oilfield for Downhole Drilling Motors. -40 is designed for use mainly under lubricated conditions and shows excellent wear resistance, low static and dynamic friction coefficient. |
