NonFricCylinder

PAT./PAT.PEND.

nonfriccylinder_main
Device overview The Non Fric Cylinder controls the looseness and tension of the dancer roll while lowering mechanical loss by using air.
Special features
  • Capable of operating by micro-pressure thanks to the reduced friction and mechanical loss by the air gap in the sliding part
  • Operating cylinder is very light, made from CFRP (Carbon Fiber Reinforced Plastic).
  • Long stroke production
  • Low maintenance
  • Simplified structure compared with conventional products prevents failure due to rubber getting caught.
Use 
  • Dancer control device for web transport line
  • Reeling machine touch roll
