Innovative rack - in conjunction with High Performance Linear Systems

Advantages at a glance:Assembly steps:
  • Very short assembly times
    The time required for for assembly has been cut by up to 50%, depending on the application.
  • Maximum assembly precision
    Far less effort is necessary to achieve optimal overall precision of the linear drive.
  • Optimized assembly ergonomics
    The assembly process is simple and effortless, reducing the physical strain on the assembly team to a minimum.
  • Extreme ease of assembly
    Machine builders no longer have to focus on an assembly friendly mounting of the rack. This opens completely new design possibility.
  • The rack is positioned on the mounting surface
  • Cylinder head screw are inserted and screwed in
  • Eccentric sleeves are fitted
  • The rack is clamped by tightening the sleeves
  • The screws are tightened to full torque

High Performance Class rack - in conjunction with High Performance / Performance Linear System

Areas of application for the High Performance Rack can be found everywhere in situations requiring the mastery of high accelerations or moving large masses. In other words, always where high feed forces must be transferred.

Significantly improved characteristics in:

  • Hardness and strength in the depth hardness and core structure
  • Permissible torsional and bending strain
  • Fatigue strength for oscillating stress
  • Wear resistance
  • Service life

A hole pattern harmonized to highest feed forces:
