FAQ

Do you have questions about the Hansen P4 UniMiner Gear Unit? Below are some of our most commonly asked questions, or you can view our Support area under Knowledge for more frequently asked questions and answers.

Hansen P4 units use one of the following systems:

  • Splash Lubrication (standard with horizontal shaft gear units for speeds between 750 and 1800RPM at the high speed shaft.  Gears and output shaft bearings are lubricated by immersion in the oil bath.  Oil splash from gears fill the oil pockets in the housing, assuring gravity circulation lubrication of the bearings via channels in the housing and covers.)
  • Force Feed Lubrication (all rotating elements above oil bath level are lubricated by a gear pump forcing the oil through pressure lines.  Forced feed lubrication is available as circulation lubrication or pressure lubrication.
