XPC+ bevel gearboxes

  • XPC+ bevel gearbox with smooth shaft

  • Premium Linear System with XPC+ bevel gearbox with slotted holes and innovative rack INIRA®
  • XPC+ bevel gearbox with slotted holes and pinion

Compact and powerful

The XPC+ bevel gearbox is distinguished by small reduction ratios (i=1 and 2) in the right-angle stage. The product structure has a positive impact on temperature development at the gear­head, so that less heat builds up in the system. The outcome: higher positioning accuracy for the system as a whole.

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.


The right-angle design allows for shorter machine concepts due to being short in the axial plane.


Extremely reliable gearboxes prevent cost-intensive machine breakdowns. 

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.

Intelligent design which reduces friction losses to a minimum

Special XP+ output for higher power transmission

High toothing quality ensures:

  • Improved load bearing capacity and therefore higher torque
  • Precision thanks to minimum torsional backlash
  • Extremely smooth operation and stable running characteristics

Low temperature development, also at high speeds

Ideal for open system concepts: no external screws and functional beading integrated in the housing

Metal bellows coupling at the input: length compensation to protect the motor bearing

The XPC+ compared to the industry standard

XPC+ – Your Xtra productivity, precision and space saving

Are you looking for a gearbox far exceeding industry standards in terms of torque, breakdown torque capacity and torsional rigidity?
The XPC+ in the alpha Premium Line offers numerous technical benefits that improve performance several times over, for example with very short cycle times and optimal controllability of your drive axis. This compact “powerhouse” also gives you the option of reducing the installation space still further.
