Standard Specifications

 3 INCH STANDARD TYPE 
 กฐ Diameter before rotating = 75mm     กฐ Diameter after rotating = 75mm  
กฐ Inside diameter of suitable core = 75.5~76.8mm

Structure and Operating Principle

 Main action principle of friction shaft is fill compressed air into friction shaft to expand rubber tube and then move up each torque assembly to extend. But in accordance with assure air pressure of value to decide each torque assembly of slippage. For the convenience to control tension in each material when rewinding on reel slitting.

Purposes

FR50 Type Air and Tension Concern

        The friction air shaft is an especially slippage and torque assured in section and individually. For application in double reel slitting machines with centre driving for the converting of material due to has no equal thickness and pulling force to break away.
