Formulae

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