KT | X-Y Positioning Tables

XY-tables of the KT series are compact two axis crossed roller tables. The tables are designed to be low profile and are equipped with precision crossed rollerways. They can operate in every orientation and can be locked in every position. For manual driven operation we supply model KT-SRM with a side mounted lead screw. Table and linear bearing specifications are similar to the KT series.


Material Table Bodies
Steel, nickel plated finishing.

 

Specification

  • Compact monolithic design.
  • Incorporates precision crossed roller bearings for high stiffness.
  • Model KT-SRM: Manual driven by a lead screw fitted with a spring-loaded double nut, division on the adjustable scale ring is 0.01 mm. (size 3) and 0.02 mm (size 6) model KT.
  • All mounting surfaces are precision ground. One flank of the slide (the side opposite to the adjustment screws) is ground parallel to the linear bearings to serve as a reference face.
  • The table-top comes with threaded mounting holes according to standard configuration. The base comes with counterbored attachment holes.
  • Accepts mounting in all orientations.
  • Orthogonalithy <10 arc-seconds.
  • For running accuracies, see table below.

 

Options

  • Precision ball screws.
  • Home/limit switches, motor flange (Nema) and coupling.
  • Linear encoders either optical or magnetic.
  • Special customer design (drawing required).
