[Technical Calculation] Cable Carriers Technical Calculation For Cable Carriers

2What is the Cable Carrier?
· It can prevent the cable and wire tubes connected to the moving parts of the equipment from twisting, stretching and entanglement
due to movement.
· It is suitable for supporting and guiding multiple cables connected to the linear motion part.
· MISUMI Cable Carrier can be ordered simply by specifying the applicable single type and no need to select the part numbers for the
link and mounting bracket, respectively.
