Double-Ball and Roller Differential Winding
Double ball and roller slip shafts use long cylindrical expansion points to support stable core contact and winding torque.
Slip Shaft
3-inch and 6-inch core winding with rubber, aluminum or paper cores where stronger ring contact and repeatable pull force are required.
| 3-inch Ring | 75.5 mm OD, 78.2 mm expansion point |
|---|---|
| 6-inch Ring | 151 mm OD, 155.5 mm expansion point |
| Core Materials | Rubber, aluminum and paper cores |
| Widths | 3-inch: 15-50 mm; 6-inch: 25-50 mm |
| Inner Diameters | 60 mm standard, 55 mm with bearing, custom to shaft core |
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: 19 grooves with kraft material, 25 mm wide double-ball plus roller slip ring.

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 DetailsBall slip shafts can be configured as center-air, pneumatic side-pressure or mechanical side-pressure slip shafts for flexible narrow-roll winding.
View DetailsKey slip shafts use rectangular metal or rubber keys to expand and contact the core for controlled differential winding.
