SLHCM-M Racks

Helical Master series racks are available with metric modules ranging from 1 to 12. They are made of 18CrNiMo5 steel, case hardened and tempered. Teeth are ground to class 5 (Modules up to 8) or 6 (Modules 10 and 12) precision, and given tip relief.

Overview

Performance data:

Available Modules: 1, 1.25, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, and 12
Available Lengths: 500mm.1000mm and 1500mm
Other lengths upon request.
Maximum Tangential Force: 410000 N

Typical Applications:

  • General Automation.
  • High Performance Heavy Duty Machine Tools.

Advantages:

  • Quieter operation thanks to an exclusive, taller, tooth profile that increases the number of meshing teeth.
  • 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.
