Details

The HTDW-5047 series combines a compact 50mm form factor with high torque for robotics joints and motion control.

Choose the 9:1 reduction version when higher speed is prioritized while keeping the same module footprint.

The 20:1 reduction option balances speed and torque for general-purpose robotic joints and actuators.

The 36:1 reduction variant is suited to low-speed, higher-torque joints where precise positioning is critical.
