порошковой металлургии куста

1. Can be a long time without oil lubrication conditions. 2. More suitable for low-speed heavy working conditions, has good wear resistance and low coefficient of friction. 3. Applicable to reciprocating, rotary and intermittent film movement, difficult to form the site. 4. Applicable to -40 +300 temperature range. 5. Has the corrosion resistance and chemical stability. 6. Free maintenance, long service life. metallurgy powderbush as a whole sleeve, flange and bearing sets of similar scope, the overall direct bearing sets can be matched with the HZ000, its tolerance and bearing with the same choice.
