Product Details

  1. Excellent wear resistance due to the boundary surface performance and fluid lubrication (two to three times better than that of DDK05).
  2. Excellent load resistance (two to three times that of DDK05).
  3. Lower friction than DDK05.
  4. Excellent cavitation resistance compared with DDK05.
Major Applications

Shock absorbers, gear pumps and PS pumps
