TUB Actuator:

Simple architecture:

  • All Mechanics on same Axis
  • Big diameter of spiral raceway with one or several raw of balls
  • Bal screw naturally protected by design

Compact and modular :

  • Motor located inside the inner tube – Reduction of number of mechanical parts and overall volume
  • Maximum Stroke with a low dead Length

Excellent resistance to buckling :

  • Large diameter tubes provides an excellent resistance to buckling  for a small weight

Weight Savings :

  • Significant  weight saving when high static loads are required
  • From -15% to  -50% Vs. Standard EMA.
  • From -30% to -60% Vs EHA.

  • Ultimate load : 8500 daN
  • Stroke : 270 & 440 mm
  • Speed : 80 mm/s
  • Diameter : 85 mm.
  • Weight :  8,5 Kg (long one)
