Overview

Performance data:

Available Modules: 2, 3, 4, 5, 6, 8, and 10
Available Lengths: 500mm.1000mm and 1500mm
Other lengths upon request.
Maximum Tangential Force: 150000 N

Typical Applications:

  • General Automation.
  • Machine Tools.

Advantages:

  • Better finishes thanks to lower vibrations due to stiffer racks.
  • Heavier loads, thanks to an optimized tooth profile with thicker, full-fillet tooth roots.
  • Easier installation, due to a better tolerance to vertical misalignments.
