PAT./PAT.PEND.

linearguideaircylinder_main
Device overview Like the Non Fric Cylinder, this device controls the dancer roll by using air, but it can be used in configurations other than vertical.
Special features
  • Long stroke production with low friction, low mechanical loss and lightweight in the same manner as the Non Fric Cylinder
  • High accuracy, high rigidity
  • Extremely robust to unbalanced loads
  • High loads can be added to the cylinder lot (Linear guide).
  • The piston part is integrated with the linear guide using ball bush.
Use
  • Dancer control device for web transport line
  • Reeling machine touch roll
  • Shock absorber
