Slip Shaft

Controlled winding torque for slit roll quality.

Stretch-sensitive film, lithium battery film and other materials that require low starting tension.

  • Center-air-pressure slip shaft structure designed for low starting tension.
  • Suitable for stretch-sensitive film slitting and lithium battery film slitting.
  • Can work from approximately 0.1 kg air pressure when the application requires a very light winding force.

  • The ring is built from roller positioning balls and bearings.
  • 3-inch ring outside diameter is 75.5 mm, expanding to 77.8 mm at the highest point.
  • Suitable core inner diameter is 76.2 +/- 0.2 mm for rubber, aluminum or paper cores.
  • Standard widths include 10, 15, 20, 25, 30 and 35 mm; other widths can be designed to order.
  • Standard inner diameter is 50 mm.

Selection Notes

Confirm core material, core inner diameter, required width, winding tension range, shaft structure and whether the application needs low starting tension or higher roll-holding force.
