1. Steel bronze powder with PTFE/Pb dry bearings 1. PTFE/Pb mixture 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder 0.20-0.35mm, provides Max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE-lead mixture.
3. Low-carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating 0.002mm, provides good corrosion resistance.
5.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. Also performs well with lubrication.
2.Typical Application:
an meet the demanding criteria for long life and trouble-free performance with or without lubrication.

As a basic heat exchange equipment, the finned heat exchange coil is composed of a base tube and fins spirally welded on the outer surface of the base tube. It is a special shape formed by coiling straight tubes through a coil machine and other equipment Finned tubes
Compared with the finned straight tube, the finned coil has a larger surface area under the same consumption of metal materials, which is the first time to enhance heat transfer from an intuitive point of view, but in fact, the increase in the heat transfer area also brings In order to improve the heat transfer coefficient, to achieve the purpose of secondary heat transfer enhancement.
