8443919090 Differential Slip Ring


Φ78mm Differential Slip Ring


Φ78mm high speed slip ring

Easy Disassemble Differential Slip Ring Steel Material Key Type High Speed

Brief introduction

    Easy disassemble differential slip ring mostly used in the machine which has big dust and the environment is not so good place. It is separate parts for the differential shaft and can replaced separately. The amount of slip exactly compensate for the difference in speed, thus it can control the tension of each roll precisely, which ensure the winding quality. And easy disassemble means the customer can disassemble the ring easy and maintenance will faster and costly.


Size of normally differential ring

Outside diameter: Φ75.5mm

The maximum action diameter: Φ78mm

Standard width: 25mm(can change to other size if needed)

Standard internal diamete: Φ60mm (can change to 50mm or 55mm or other sizes if needed)

  • Difference in material thickness often arises when unwinding plastic films or other material. In the process of constant winding, this difference can lead to obvious discrepancy in outside diameter of roll, and slight discrepancy in winding torque under this situation. After some winding rotation, some rolls may start to loosen, leasing to quality decline in product eventually.
  • Our differential air shaft with slipping friction can ensure the highest winding quality, and by keeping proper tension on all rolls throughout the winding operation, materials will not show any problem.
  • It works under the theory that friction rings slip constantly to keep same tension, some rings slip faster than others. So tension of each roll can be controlled accurately, and permanent tension can also be gained to guarantee the quality of roll.


  1. The differential shaft can meet the requirements of high-speed, error in material thickness, multi-stage tension control, high precision requirement on tension control, ,uniformity on the winding end.
  2. The differential ring on differntial shaft can slip independently, it is the main part for differential shaft which is with tension adjustment.
  3. Controlled by the tension system, make the compressed air which has a certain pressure come to shaft core, so that it will produce friction torque between the friction parts and the slip ring.
  1. The use of differential shaft ring improves the stablity of the slitting machine,espceially for high speed machine.
  2. The differential shaft combined by differntial rings can make the accuracy of the winding and the automation.
  3. Differential shaft ring to wind or unwind precious materials, metal foil and special paper roll, can greatly reduce the cost of production.
    Applicable to the rewinding or slitting of packaging materials such as web, plastic sheet, aluminum foil, PVC, plastic film, insulating material and so on. It is an ideal equipment for fine cutting materials, Frame fixed good, small gap, high precision, to ensure the slitting machine can operate in high-speed.
