Product Overview

High-torque T-type integrated robot joint module delivering up to 70 Nm peak momentary torque in a 73 mm diameter housing. Designed for load-bearing joints in collaborative robots, humanoid platforms, and exoskeletons.

Delivers up to 70 Nm peak momentary torque in a 73 mm diameter package — designed for load-bearing joints such as robotic shoulders, waist axes, and heavy-payload wrist assemblies.

🔶 T-Type vs F-Type — What's the Difference?

The T-type (eRob70T) uses a through-shaft output configuration that delivers significantly higher torque capacity — up to 70 Nm peak momentary torque— compared to the F-type's 35 Nm. The T-type is 73 mm in diameter and 99 mm in length, optimised for load-bearing joints. The F-type (eRob70F) is lighter (0.77 kg vs 1.24 kg) and better suited for distal joints where weight saving is the priority.
