Features and benefits

The servo gearboxes PT complete the whole range of our servo gearboxes that consist of high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes as well as various combinations thereof. All common servo motors can be easily installed with all sizes of our gearboxes. Our PT servo planetary gearboxes guarantee high stiffness and reliable transmission through their unique design. All ring gears, planet gears and sun pinions are case – hardened and ground. This provides an outstanding transmission quality and allows for precise positioning tasks.

  • case – hardenend and ground ring gears with minimized run – out
  • case – hardenend and ground planet gears and sun pinions
  • high transmission quality through high-precision components
  • high positioning accuracy
  • high torsional stiffness
  • solid bearings
  • compact design
  • high permissible axial and radial loads
  • extremly high torsional stiffness due to the use of large taper roller bearings
  • suitable for all mounting positions
  • protection class IP 65
  • high permissible emergency off-torque through form-locking power transmission
  • smooth running through optimized gear geometry
  • reduced friction due to minimized sealing diameters
  • backlash-free power transmission by force-locking motor clutch
