Product Overview
High-torque hollow-shaft joint
The CubeMars AKH70-48 V1.0 delivers 74 Nm continuous and up to 222 Nm peak torque at 1396 g, a torque density of about 159 Nm/kg. A three-stage 48:1 planetary gearbox and dual 21-bit encoders provide high output with predictable, accurate closed-loop motion.
A 7 mm hollow shaft lets power and signal cables route through the centre, reducing external wiring, and dual CAN interfaces allow multiple actuators to be daisy-chained on one bus for complex robotic arms and legged robots.
