Achieves a 30% lighter design than the CSF unit series. Contributes to lighter and faster equipment and robots with greater load capacity.

The lightweight, super flat, and high stiffness model of the CSF-mini unit lineup. Achieves a much flatter design than the previous series and high stiffness by adopting a cross roller bearing in the main roller bearing.

The standard Harmonic Drive® model. The components of this unit product have been made easier to handle. It includes an accurate high stiffness cross roller bearing in the main roller bearing to enable direct support of external loads.

The standard Harmonic Drive® model. The component is comprised of only three basic components. This type can be directly embedded in machinery and equipment to increase freedom of design.

This model pushes flatness to new extremes. In comparison with the CSG/CSF Series, this module reduces the length in the shaft direction by about 50%.

This series achieves a boldly thin (flat) structure and hollow structure.

This model pushes flatness to new extremes. In comparison with the CSG/CSF Series, it halves the length in the shaft direction.

Achieves a 30% lighter design than the previous SHG unit series. Contributes to lighter and faster equipment and robots with greater load capacity.

The hollow Harmonic Drive® model. The components of this unit product have been made easier to handle. It includes an accurate high stiffness cross roller bearing in the main roller bearing to enable direct support of external loads.

This unit type product with input shaft adopts a high stiffness bearing (cross roller bearing) in the Harmonic Drive®.

The component type Harmonic Drive for this series is a simple unit type that incorporates a cross roller bearing.

This simple unit type with hollow structure embeds a cross roller bearing only in the component type.

The hollow Harmonic Drive® model. The component type is comprised of only three basic components. This type can be directly embedded in machinery and equipment to increase freedom of design.

This model pushes a lightweight design, ultra flatness, and a large hollow bore to new extremes.

This model pushes the flat shape to new extremes. The SHD-2SH Series halves the length in the shaft direction compared to the SHG/SHF Series.

This Harmonic Drive® features a structure with a large hollow bore and small outer diameter. This allows for more compact and space-saving designs for applications such as axes on the ends of robot arms in which cable routing would be an issue, or in various machines and equipment.

This type pushes the flat thin type to its limits.

This flat thin type is for high torque. It supports higher torque capacities than the FB Series.
