A hollow bore rotary table has a central through-hole extending completely through its rotating axis. Precision bearings of Hollow Aperture Rotary Tables—crossed roller, angular contact, or worm drive—support the rotating assembly. An internal motor, usually a direct-drive torque motor or servo-gearbox combination, drives rotation. The hollow bore allows media pass-through: pneumatic lines, electrical cables, laser beams, or fluid hoses

Design description of TallMan Robotics Hollow Bore Rotary Tables

Hollow bore rotary tables are precision motion devices that provide controlled angular positioning while featuring a central through-hole for internal routing or structural integration. The hollow shaft allows vacuum paths, or optical components to pass through the center without external obstruction.

FAQs about Hollow Rotary Tables

Can I pass electrical cables through the hole?
Yes, you can route power, signal, or Ethernet cables directly through the bore.

Does a hollow bore table eliminate drag chains?
Yes, because utilities go through the center instead of looping outside.

Do I need an external brake?
No, the motor’s holding torque or a built-in locking mechanism stops the table.

Is maintenance complex?
No, sealed bearings and direct-drive motors require minimal maintenance.

Can a hollow bore table work vertically?
Yes, but you need a model designed with vertical preload on bearings.

Which industries use these tables?
Robotics, laser welding, medical device assembly, and semiconductor manufacturing.
