Expanding core shafts
Expanding Core Shafts

XC Air differential shaft (Friction shaft,slip differential shaft)
3''outer diameter:φ75 Expand diameter:φ78mm
  1. Applicable tube ID:φ76±0.2mm
  2. Inside diameter(ID):φ45mm
  3. Differential ring:standard width 40mm,other width:30,40,45mm
Piston standard number:8pcs,other 6,10 or 12pcs.
It is suitable for packaging film and common film slitting rewinding(8 pistons)
12 pistons are suitable for lithium battery pole piece,the diaphragm slitting.
Central pressure shaft,pneumatic tightens,pneumatic differential slip.high accuracy and performance.a wide range of tension control.
Apply to full automatic transfer rewind,assure core don't slacken off.
Fit the shouter axis,winding excellence.
To achieve extremely low tension-friction,have application in the thinnest(10U) PET film,electronic film splitting.
Very successfully used in lithium batterieres diaphragm,lithium battery pole piece,power battery pole piece,low tension PET film,electronic film.
DS Air differential shaft
3'' outer diamerer:φ75 Expand diameter:φ78mm
1)Applicable tube ID:φ76±0.2mm
2)Inside diameter(ID):φ45mm
3)Standard width:50mm
Central pressure shaft,pneumatic tightens,pneumatic differential slip.high accuracy and performance.a wide rang of tension control.
Apply to full automatic transfer rewinding,assure core don't slacken off.
It is especially suitable for flexible packaging composite film slitting rewinding.
GZ Air differential shaft
3''outer diameter:φ75 Expand diameter:φ78mm
1)Applicable tube ID:φ76±0.2mm
2)Inside diameter(ID):φ60mm
3)Standard width:25mm
Can form central pressure type,pneumatic side compression type,mechanical side pressure type differential shaft.Center pneumatic friction torque mechanical properties loss small,according to the pressure to get accurate proportion to the size of the torque,realize tension from small to large,large range accuracy control.
  1. Differential shaft slitting coil width the most narrow 5mm,other any size.
  2. The core independent design consists of 60mm diameter solid steel,large diameter base shaft=high strength+low deflection.Multiple bladder base shaft for highest strength/lowest deflection.
  3. Suitable for high speeding slitting machine,heavy ,large volume diameter material slitting.In all kinds of paper roll slitting, adhesive tape industry with very well.
  4. Equipped with sliding ring,coil easy handing,3 meters long shaft rolling also becomes easy.
  5. ZJZ shaft,make the GZZ excellent performance ,can be applied to hard tube core outside of the paper tube,firmly seize the hard tube core.
JS Air differential shaft
3''outer diameter:φ75 Expand diameter:φ78mm
1)Applicable tube ID:φ76±0.2mm
2)Inside diameter(ID):φ50mm
3)Standard width:15,20,25,30,35mm,other size can made by request.
6''outer diameter:φ150 Expand diameter:φ156mm
1)Applicable tube ID:φ152.4±0.2mm
2)Inside diameter(ID):φ60mm
3)Standard width:50mm,other size can made by request.
Could manufacture central pressure type,pneumatic side compression type,high performance differential slip get lower mechanical loss, accuracy torque,to control tension in a wide rang with great precisong.the most widely application,key tooth can take any tube core.
