Nabtesco Component Sets

Precise, reliable and powerful.

Nabtesco component sets stand for maximum precision, extremely low vibrations and low inertia. Our ingenious two-stage cycloidal design makes the gears insensitive to shock loads and allows high torques. The force transmission via rollers guaranteed high-efficiency ratio of up to 85% and long service life. The component sets of the RV-C and RV-N series also feature integrated angular ball bearings. Hence, there is no need for the customer to provide bearings, as well as the manufacturing costs for the bearing mounts.

Nabtesco Cycloidal gearboxes feature high precision, high performance and a long service life


The RV-C series features a hollow shaft with a diameter of up to 138 mm. This allows the feed-through of data cables and supply lines.

  • Hollow shaft component set
  • T: 98 – 11.760 Nm
Nabtesco component set of cycloidal gears


We developed the RV-N series as a very compact, lightweight and high-performance solid shaft gear. These gears are used in applications with limited space that require high torque performance.

  • Solid shaft component set
  • T: 245 – 7.000 Nm
  • i: 41 – 203,52
Nabtesco cycloidal gears offer precise, robust, compact performance


The RV series represents the “basis” of our entire product line. These are component sets without integrated angular ball bearings, which makes them especially compact. The gear sets can be combined with different external output bearings.

  • Solid shaft component set
  • Without output bearing
  • T: 137 – 5.390 Nm
  • i: 57 – 192,4
nabtesco cycloidal gear


The RF-P series is a completely new development! Due to their high output speed, these component sets are ideal for highly dynamic pick & place, handling and positioning applications. They are used especially in arm axes of Delta and SCARA robots or in the wheel drives of driverless transport systems.

  • Solid shaft component set
  • High output speed
  • T: 190 – 320 Nm
  • i: 31 – 56
  • n: bis 200 min-1
