Hollow shaft rotary actuators from Intellidrives have a large-diameter hollow shaft

Hollow shaft rotary actuators in four stage sizes with center apertures from 33 to 100 mm offer optimized load capacity, torque, speed, and resolution. Features include a large-diameter hollow shaft, high rigidity, and position feedback. A motor encoder allows closed-loop operation for bidirectional speed and position control, which are critical for high-speed motion contouring.
