Formula   Describtion
SFLB = 2 * FLB = Calculation of maximum travel length, unsupported with sag
SFLG = 2 * FLG = Calculation of maximum travel length, unsupported straight
BRI ≥ Ba + 5 = Calculation of the minimum guide trough width
HRI ≥ 2 * ha = Minimum height of guide channel on gliding application
K = R * π + (2 x T) = Add-on for bending radius
LK = S/2 + ΔM + K = e-chain® length, fixed end outside the
center of the travel distance (on FLG, FLB and ΔM)
LK = S/2 + K = e-chain® length, all installation types, fixed end in the center of the
the travel distance, except circular motions and most long
travel distances (on FLG, FLB) [m]
LK = S/2 + K2 = Calculation of chain lengths for long travels,
fixed end in the center of travel
