ROLL AXIS - ACCESSIBLE SEALS

 

Clansman Advantages

  • Clansman Dynamics offer 360 degree rotation as standard (competitors can provide this too).
     

  • 360 degrees rotation means a hydraulic rotary joint to get oil down to the grippers.
     

  • And there is far less danger of dirt ingress.
     

  • There is no gearbox. This avoids backlash and wobble.
     

  • The motor is the same direct drive motor as on Axes 1 and 4 so there is no wobble.
     

  • Only one spare motor seal set or motor need be carried as a spare and 3 axes are covered.
     

  • Clansman Dynamics puts the seals for this joint in a simple seal housing at the top of axis 6.
     

  • Competitors put the seals for this joint down in between the 2 taper roller bearings.
