SYHD-Ill series performance parameter

Simple combination type ( super flat hollow shaft )

SYHD-III series is the type pursuing flat structure to the extreme.

Its axial length is half of that of SYHS series.

The flexspline adopts ultrathin hollow flanging structure and its output side is installed with high rigid crossed roller bearing.

Suitable for the application with requirement on flat design.

Product Features
1. Ultra thin · Hollow structure
2. High rigidity
3. High torque capacity
4. Input/output coaxial
5. Excellent positioning accuracy and
rotation accuracy

Typical Applications

Humanoid Robots – Compact actuation for dexterous joints
Metal Working Machine Tools – High-precision rotary axes
Industrial Robots & Collaborative Robots (Cobots) – Reliable joint actuation
SCARA Robots – Smooth, backlash-free transmission
Medical Equipment – Precise, reliable motion for surgical and diagnostic devices
Aerospace – Robust performance under demanding conditions
