BRa = Guide trough outer width [inch]
BRi = Guide trough inner width [inch]
D = Over length energy chain radius in final position [inch]
D2 = Over length for long travels gliding [inch]
FL B = Unsupported length with sag [ft]
FL G = Unsupported straight length [ft]
FL U = Unsupported lower run [ft]
FZmax = Maximum additional load [lbs/ft]
H = Nominal clearence height [inch]

R = Bending radius [inch]
RBR = Reverse bending radius [inch]
S = Length of travel [inch]
S/2 = Half length of travel [inch]

Formula   Describtion
SFLB = 2 * FL B = Calculation of maximum travel length,
unsupported with sag
SFLG = 2 * FL G = Calculation of maximum travel length,
unsupported straight
BRI ≥ Ba + 5 = Calculation of the minimum guide trough width
HRI ≥ 2 * ha = Calculation of the minimum guide trough height
K = π * R = Add-on for bending radius
LK = S/2 + ΔM + K = Calculation of chain lengths - for all types of applications,
fixed end is outside the center of travel (with FLG, FLB and ΔM)
LK = S/2 + K = Calculation of chain lengths for all types of applications, fixed end in the center of travel,
except rotary movements and most long travels (with FLG and FLB) [m]
LK = S/2 + K 2 = Calculation of chain lengths for long travels,
fixed end in the center of travel
