Extended Length Positioning Stage

These positioning stages are longer versions of the “square geometry” linear positioners. Their extended length permit a larger number of rolling elements in the bearing system to provide increased load capacity with the same cross section.

Low friction linear adjustment with no backlash or side play
Factory preloaded to provide dynamic stability and minimum run-out
Straight-line accuracy of 0.00008 in/in of travel
Aluminum top and base with precision ground mounting surfaces and black anodize finish
Selectable bearing systems: ball bearings for economy or cross roller bearings for greater load capacity
Selectable drive mechanisms: Micrometer (English or Metric); Fine screw (64 pitch); Differential screw; Digital micrometers
Locking screw to positively lock stage without affecting position (standard on most models)
