Energy chain E2C.21 series | One-piece, completely closed | Inner height: 21.2mm
Inner height hi: 21.2mmInner width Bi: 25 - 68mmBend radii R: 35 - 180mmPitch: 33.3mmMore useable interior space while the outer height is the same as the E2/000 e-chains®Easy to open - openable along the inner radius, from both sides (left or right)Greater strength for unsupported applications20% to 30% larger sliding surfaces for longer service life in gliding operation compared to previous series E2/000Integrated positional system 2.5mmCable-friendly due to very smooth contours7dB(A) quieter due to integrated brake

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
