RPK+ hypoid gearhead

  • RPK+ hypoid gearhead with flange

  • RPK+ hypoid gearhead with pinion

  • Premium Linear System with RPK+ hypoid gearhead and innovative rack INIRA®

Power and precision in a compact design

The Premium planetary gearhead RP+ are now available in a right-angle version RPK+ with hypoid gearing. The axis offset of hypoid gearheads allows both higher ratios in one section (ratio i = 3 – 10) as well as higher torques compared to bevel gearheads.The high torque density allows for an extremely compact, space-saving design. The mesh frequency and high torsional rigidity of the gearhead are also extremely impressive since they ensure a higher degree of positioning accuracy and extremely smooth operation.
