The hollow shaft allows passage of cables, pneumatic lines, fluid hoses, or optical beams directly through the table axis, eliminating external drag chains. The drive system integrates a stepper motor or a servo motor with a precision gear reducer (harmonic, planetary, or worm). Crossed roller bearings support the hollow output, providing high axial, radial, and moment load rigidity. An externally mounted Omron sensor provides closed-loop feedback for angular positioning accuracy typically within ±10 arcseconds and repeatability of ±1 arcsecond. Engineering specification of TallMan Robotics Electric Hollow Rotary TablesElectric hollow rotary tables are precision motor-driven rotary positioning platforms equipped with a central through-hole, designed to deliver controllable angular displacement and indexing for automated machinery.

Geared versions (harmonic, planetary, or worm) use a motor plus reducer, providing higher torque density and self-locking capability (worm gear) but introduce backlash and lower maximum speed. Choose direct-drive for precision contouring or laser scanning. Choose geared for heavy loads or power-off holding.You are welcome to watch more projects or visit our website to check other series or load down e-catalogues for further technical data.
