Item
Basic specifications
Reference information
Determine the support member bending radius based on the allowable
bending radius of the cable/tube to be installed.
Check the allowable bending radius recommended by
the cable/tube manufacturer (for repeated bending).
Refer to the following guideline.
Cable with shield = Max. cable outer diameter × 8
Cable without shield = Max. cable outer diameter × 6
Tube = Max. tube outer diameter × 9
Select a support member bending radius
greater than the allowable bending radius of
the cable/tube.
