Nabtesco gearheads

Ready to install for fast integration.

Nabtesco gearheads are completely sealed gear units. They are filled with grease, encapsulated and ready for installation. To reduce the design and assembly costs, we integrate the motor adapter plate and the motor shaft coupling for servo motors in the gearheads. The gearheads are based on our different component sets – with a hollow shaft or solid shaft – and their design features bring numerous advantages.

Nabtesco component sets stand for maximum precision


These gearheads feature a large hollow shaft for the feed-through of cables and supply lines. The hollow shaft rotates at the output speed. This series is available for right-angle (RDR-C) or straight (RDS-C) installation, as well as for installation with a pulley input (RDP-C).

  • Hollow shaft gearhead
  • T: 98 – 3.136 Nm
  • i: 81 – 258
Nabtesco RD -C gearheads


The solid shaft gearheads of our new RH-N series are based on the RV-N component sets. They feature an integrated input gear and a motor flange for all standard motor types. This makes them ideal for use in machine tools, in modern rotary tables and in different handling applications. The gears are manufactured locally and adapted for individual applications as required.

  • Solid shaft gearhead
  • T: 245 – 7.000 Nm
  • i: 41 – 203,52
Nabtesco solid shaft gearheads


We designed these gearheads to be especially lightweight and compact. They can be operated with a right-angle (RDR-E) or straight (RDS-E) pre-stage or alternatively by means of a pulley input type (RDP-E).

  • Solid shaft gearhead
  • T: 58 – 3.136 Nm
  • i: 31 – 185
Nabtesco lightweight gearheads


The solid shaft gears of the RA-EA/EC series are based on the RV-E component sets and are optimized for the precise positioning of chain or disk magazines.

  • Solid shaft gearhead
  • For magazines and change systems
  • T: 167 – 1.568 Nm
  • i: 80 – 171
Nabtesco Gearheads


These reduction gearheads (based on the RV gear sets) are designed for high output speeds and are therefore ideal for the automation of robot axes, machine tools and conveyor systems.

  • Hollow shaft gearhead
  • High output speed
  • T: 69 – 980 Nm
  • i: 10,74 – 31,43
  • n: bis 270 min-1
