Description

Structure: steel Backing + Bronze Sintere + PTFE/Pb

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. steel backing, gives exceptionally high load carrying capacity, excellent heat dissipation. Have very good corrosion resistance.

Product Feature


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. Very high chemical resistance, low absorption of water and swelling. Also performs well with lubrication. Bronze backing provides improved corrosion resistance compared with ZIX SF3

Application


Can meet the demanding criteria for long life and trouble-free performance with or without lubricant, of high safety factor even...It is especially for high chemical resistance request. Steel metallurgy industry such as bushes for roller grooves of successive casting machinery, cement grouting pumps and screw conveyers for cement, it can also be composed in steel housing or fabricated into flanged bushes which can move both in radial and in axial directions. The bearings are particularly appropriate for high temperature environment where no oil is efficient and the machine must be under successive long period working condition
