HTDW-7535-02-CNE Planetary Joint Module with Cross Roller Bearing – 35:1, 20Nm, 70Nm Peak, CANFD/CAN

The HTDW-7535-02-CNE is a heavy-torque planetary joint module with a cross roller bearing output, engineered for large robotic arms, legged robots, and high-load automation joints. At 75 × 56 mm and 850 g, it delivers 20 Nm rated torque and 70 Nm locked-rotor torque through a 35:1 planetary reduction, with dual 14-bit encoders for closed-loop position, velocity, and current control.

Key Features:

• Cross roller bearing output – high radial/axial stiffness and moment rigidity for demanding joint applications.
• Planetary gear reducer – 35:1 reduction, high drive efficiency in a compact body.
• 20 Nm rated / 70 Nm locked-rotor torque – the highest torque in the HTDW lineup.
• Self-designed brushless DC motor – low cogging torque and low torque ripple.
• Dual 14-bit absolute encoders – accurate position and torque feedback for closed-loop control.
• CANFD / CAN communication – 5 Mbps baud rate, easy integration with existing robot control architectures.
• Wide voltage range – 12–50.4 V DC input, 24 V rated.
