Closed-loop ball-screw linear stages with linear scale feedback for medium to long travel under heavy loads.

The KA series are closed-loop motorized linear stages for medium to long travel, from 50 mm to 1000 mm. An externally mounted linear scale (grating ruler) gives a closed-loop resolution of 1 µm on KA050–KA400 and 0.5 µm on KA600–KA1000 when the stage is run from an MC600 or TMC series controller. A rigid U-section aluminum base, precision ball screw, linear-slider guides and a high-performance shaft coupling make the stages suitable for heavy loads and multi-axis assemblies.

Key Features

  • Fagor MX/MKX series linear scale for closed-loop positioning: 1 µm (KA050–KA400) or 0.5 µm (KA600–KA1000) resolution
  • U-section aluminum alloy base, precision machined and black anodized, for high rigidity under heavy load
  • Precision ball screws (φ12 × 4, φ16 × 5 or φ25 × 5) with precision-grade linear-slider guides
  • Horizontal load capacity of 30, 50 or 80 kg depending on model
  • Two-phase 57 stepping motor as standard; AC servo motor (100–400 W) optional
  • Optional stainless-steel dust cover protects the screw and guides from particles and dust
  • Built-in limit and origin sensors; DB9 connectors for stage and linear scale

Typical Applications

  • Long-travel positioning of samples, optics and fixtures
  • Multi-axis XY and XYZ stage assemblies
  • Heavy-load positioning in automation equipment
  • Automated inspection and measurement systems
