Key features

  • One-piece metal body with no backlash
  • Round-shaped slits disperse stress concentration
  • Inner relief area prevents shaft interference
  • Set-screw and side-clamp versions; A/B lengths on larger sizes
  • For encoders, stages and part feeders

Specifications

Body material Al-7075-T6, anodized
Screws SCM435, black oxide
Clamping Set-screw / side-clamp (C)
Shaft tolerance h7 recommended
Options Keyway
Applications UVW stages, XY stages, part feeders, encoders
