Ball-Type Differential Winding
Ball slip shafts can be configured as center-air, pneumatic side-pressure or mechanical side-pressure slip shafts for flexible narrow-roll winding.
Slip Shaft
Narrow-width slitting from 5 mm and general film, paper and label rewinding where roll-specific torque compensation is required.
| 3-inch Ring | 75.5 mm OD, 78.2 mm maximum expansion |
|---|---|
| 6-inch Ring | 151 mm OD, 155.5 mm maximum expansion |
| Core Sizes | 76.2 +/- 0.2 mm and 152.4 +/- 0.2 mm |
| Widths | Single-ball 10-25 mm; double-ball 15-50 mm |
| Minimum Slitting Width | From 5 mm depending on shaft and ring layout |
Slip Ring
Slip rings are shown as compact thumbnails because many source images are small. This keeps the visual quality natural while still showing the available ring forms.
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.
Technical Data
Values are translated from the supplied product document and should be confirmed against the actual shaft structure, ring width, groove material and air path before final selection.
Test condition: 3-inch double-ball slip ring, 25 mm width, 60 mm inner diameter, 20 x 3 groove with wool felt.

Air slip shafts combine pneumatic core locking with controlled differential slip for accurate torque and stable multi-roll winding.
View DetailsLow tension slip shafts use roller positioning balls and bearings to start and regulate winding at very low air pressure.
View DetailsDS slip shafts provide pneumatic locking and pneumatic slip for accurate torque in medium tension film slitting and rewinding.
View DetailsDouble ball and roller slip shafts use long cylindrical expansion points to support stable core contact and winding torque.
View DetailsKey slip shafts use rectangular metal or rubber keys to expand and contact the core for controlled differential winding.
