JS Thimble Jacking Stages – JS Series


JS Series Thimble Jacking Stage

Thimble jacking stages are precision linear motion devices with a clear bore flange/bellows assembly. A knurled Acme screw threaded collar actuates the linear drive. The top flange slides up and down on three stainless steel guide pins maintaining a ridged mount.


Thimble jacking stages are ideal for precision linear probe positioning of distances less than 2″. Rotating the Acme screw threaded collar jacks the top flange with a range of one or two inches. One rotation of the Acme threaded collar moves the top flange 0.1″ (0.001″ per gradation).

  • 2.75″ O.D. rotatable top flange
  • 2.75″ O.D. base flange
  • 1.39″ I.D. bellows
  • Bakeable to 200°C
  • 0.001″ resolution per gradation
  • Available with optional guide bearing
