Hollow Rotary Actuator: Core Solution for High-Precision Rotary Motion

The Hollow Rotary Table is a compact precision drive unit designed for automated angular positioning. It integrates high rigidity, excellent accuracy, efficient transmission, and cost-effectiveness, making it an ideal core component for automation systems requiring precise rotary motion.

Key Design Advantages

• Hollow Structure: The central through-hole allows direct routing of cables and pipes, simplifying system layout and maintenance.

• Exceptional Rigidity: A preloaded cross roller bearing with 90° roller arrangement supports radial, axial, and moment loads, delivering over 5× the rigidity of standard bearings.

• Superior Precision: The table is reground after assembly to ensure high coaxiality. Combined with Grade 5 or higher gears and adjustable backlash, repeatability reaches ±5 arc-sec.

• Flexible Motor Compatibility: Custom input flanges and shaft interfaces enable direct mounting of servo or stepper motors.

Standard Configurations

• Coaxial direct connection

• Parallel shaft (side connection)

• Right-angle shaft

• Typical Applications

CNC indexing, robotic joints, machine tool 4th axes, automated production lines, and precision inspection systems.
