What is the meaing of Minimum Bending Radius (Static Conditions)?
The following formula can be used to determine the minimum values for the radii to which such cables may be bent for permanent training:
MBR = OD x M
Where:
MBR = Minimum radius of bend (in)
OD = Outside diameter of cable (in)
M = Diameter multiplier (Please see tables on the next page(s))
Note: The above calculation applies to STATIC conditions ONLY. Please reference the DYNAMIC conditions section below and the Sidewall Bearing Pressure section for the minimum bending radius of cable in motion.
