XP+ planetary gearbox

  • XP+ planetary gearbox with smooth shaft

  • XP+ planetary gearbox with pinion and slotted holes

  • Premium Linear System with XP+ planetary gearbox with slotted holes and innovative rack INIRA®

  • XP+ planetary gearbox with R flange

  • Installation space XP+ vs. Industry standard

  • Motor mounting alpha Premium Line Planetary gearboxes 

Perfection in new dimension

The XP+ with specially designed output and extremely compact design offers new dimensions in power transmission that far exceed industry standards. The XP+ impresses with  the highest torque density in the market – coupled with maximum torsional rigidity and titling moment capacity,

  • Shorter cycle time because acceleration is maximized
  • Higher permissible masses and process forces
  • Smoother running and higher repeatability
  • Implementation of high precision linear systems
  • Installation space savings through downsizing

Product highlights


Excellent torque density and rigidity reduce your cycle duration

Low maintenance

Highest quality standards guarantee a long service life and extend maintenance intervals.


The right-angle gearbox with very high breakdown torque capacity allows new machine concepts, for example a bearingless design.

Process quality

Constant low backlash over the entire service life of the gearbox coupled with high torsional rigidity enables the highest levels of positioning accuracy.


Extremely reliable gearboxes prevent cost-intensive machine breakdowns. 


The XP+ provides the highest torque density compared to the industry standard, enabling a smaller size to be used.

Outstanding toothing quality minimizes torsional backlash

Multiple output options

Specially designed output for transmitting extremely high torques, can withstand high tilting torques
