WORKING CONDITIONS

What Matters Most When Selecting for This Application?

  • Seventh axes typically have significant moving mass and start/stop inertia, Rated Torque Alone Is Insufficient.
  • If the output directly carries high radial forces and overturning moments, Prioritize a Higher-Rigidity Structure.
  • For long travel, also consider the rack, Overall Rigidity & Backlash of Belt or Screw Drives.

Recommended Combination

PLX090 / Hollow Rotary Table

750W Servo

WHY THIS STRUCTURE

Why This Transmission Structure Is Recommended?

PLX Disc-flange outputs suit rigid mounting and higher loads

Connects Easily to Gears, Timing Pulleys or Turntables, For long-travel loads, carefully check radial force and overturning moment.

Helical gears suit axes sensitive to noise, Smoothness & Backlash

Helps Reduce Operating Fluctuations, Repeatability Also Depends on the Rack, Linear Guides, Connections & Control Settings.

If Hollow Cable Routing Is Required, Consider a Hollow Rotary Table

First Determine Whether Cables, Or pneumatic lines must pass through the center of rotation, Then choose the hollow passage and load-support structure.
