Hollow Rotary Reducers are compact transmission units that integrate a speed reduction mechanism with a hollow output shaft for torque transfer and internal routing. Hollow Rotary Reducers,Hollow Rotary Tables are a type of gear reduction device that feature a hollow interior design.

Performance specification of TallMan Robotics Hollow Rotary Reducers

This hollow rotary actuator integrates a reduction gear train—typically cycloidal, planetary, or harmonic drive—with a central through-bore. The hollow shaft allows cables, air lines, or laser beams to pass axially. A servo or stepper motor inputs high-speed, low-torque rotation.

FAQs about Hollow Rotary Reducers

  • Can I route pneumatic hoses through the center?
    Yes, the hollow bore easily accepts pneumatic lines or electrical cables.
  • Do I need an external cable carrier for Hollow Rotary Platforms?
    No, the hollow bore replaces external cable management chains.
  • Can I use Hollow Rotary actuators in a robot joint?
    Yes, hollow reducers are standard for robotic arm wrist and elbow joints.
  • What gear types do hollow rotary reducers use?
    Four gear types dominate the market. Planetary gears deliver high efficiency and compact size at moderate torque. Cycloidal gears handle shock loads with very low backlash. Hypoid gears suit right-angle drive configurations with high torque density. Helical ring gear designs serve high-speed indexing tables where smooth rotation and low noise matter most. Each type fits different speed, torque, and accuracy requirements.
  • What bearing type supports the output flange?
    Crossed roller bearings are the standard choice. Their alternating roller arrangement handles axial loads, radial loads, and tilting moment loads simultaneously from one compact bearing unit. This gives the output flange high rigidity and minimal deflection under eccentric or cantilevered payloads. Some heavy-duty units use tapered roller bearing pairs instead for even higher radial and axial load capacity.
