Premium Linear System with RPK+

System output for even greater flexibility

Rigidity for high-precision drive solutions

cynapse® & smart services

The R-flange is standard for the RPK+. The slotted holes integrated into the gearbox flange allow easy adjustment of the gearbox with the pinion mounted on the rack.

The RPK+ for perfectly matched rack and pinion systems for high to very high demands. Typical areas of application are laser machines, wood, plastic, and composite material processing centers, cutting machine tools, e.g., HSC milling machines, as well as highly dynamic and precise handling applications.

The system output can be used to implement a wide variety of gearbox and pinion configurations. The inputs can be optimized for rigidity, feed force, or feed speed, depending on requirements.

The high torsional rigidity of the RP+ gearboxes, combined with the tilting rigidity, C2K,lin, and engagement spring stiffness, Cγ, together with a highly rigid design, have a positive effect on the natural frequency and thus on the control behavior of the machine.

With cynapse® and smart services, you can unleash the full potential of your drive system: sensor data is processed, visualized, and analyzed intelligently. Find out how the combination of gearboxes with cynapse® and our smart services can make your digital production faster, safer, and more efficient.
