E2.1微型拖链E2i.21系列，横杆可沿内半径方向从两侧打开

The unsupported length versus fill weight
X axis: Unsupported length in m FLB/FLG
Y axis: Fill weight in kg/m
Lower scale: Travel S in m
FLB = Unsupported with permitted sag
FLG = Unsupported with straight upper run

A = moving end, B = fixed end
Pitch: 33.3mm
Links per m: 30
Travel: S
e-chain® length= ^S/₂ + K

K = Surcharge for bending radius for e-chain length calculation in mm
Note: Chain length for the e-chain links is rounded up, as there are no half links.

From 10m to max. 75m
Chain length = ^S/₂ + K₂
Long travel - gliding (up to max. 100m) Here the e-chain® upper run is gliding on the lower run in a guide trough. We recommend that the project for such a system be planned by our technicians. For travels of between 4.0m and 10m, we recommend a larger unsupported energy chain.
A1 = moving end
A2 = fixed end
A3 = guide trough with glide bar
A4 = guide trough without glide bar
A5 = total guide trough length
