Series 2650

Here you can configure your e-chain system® individually. All entries and changes are taking over to the part list which is situated at the end of the page.

Series 2650 - half tube snap-open along inner radius

1. Optimised opening system for fast opening of the crossbars, either from the left or right
2. Double stop system for long unsupported lengths
3. High holding force of the crossbars
4. Glide surfaces on the side for operation "on the side"
5. Proven and-tested mounting bracket
6. Strain relief can be integrated in the mounting bracket
7. Semi-enclosed e-tube Series 2650
8. Series 2600 and 2650 snap-open along inner radius
9. Enclosed e-tube Series 2680
10. Flexible modular interior separation system
11. Easy assembly due to optimised pins
12. Also available as ESD version
13. Strain relief separator - Separator with integrated strain relief

Please note: Before using this series on long travels, please consult igus®. We recommend an e-chain® that is openable in the outer radius for long travels. Example: Series 2700

Series 2650 is suitable for the following types of applications:

Vertical: hanging applications ≤ 50 m, standing applications ≤ 3,0 m
Horizontal: unsupported applications ≤ 2,75 m, gliding applications (upon consultation)
rotary: rotating applications may be possible, please contact us

When to use Series 2650

When a medium-sized, strong system (e-chains®, half e-tubes, completely enclosed e-tubes) with 35 mm inner height is required
If an inner width up to 175 mm is required
For unsupported lengths up to 2,70 m and fill weights up to 8,0 kg/m
If an opening system is required to quickly open from either the left or right

When not to use Series 2650

If max. strength is required
E4.1 system, series E4.32
For very easy applications
easy chain®, E26
Tube with smaller bend radii 075
E2 energy tubes, series R58

* The required clearance height is HF = H + 35 mm (with 2 kg/m fill weight), this should be taken into account for all application types. Please contact us if you have particularly narrow space conditions.
** The calculated length corresponds to the chain length without mounting brackets.

A=Moving end, B=Fixed end
Pitch: 56 mm
Chain links per m: 18
Travel: S
Chain length = S/2 + K

Unsupported length

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 permissible sag
FLG = Unsupported with straight upper run

Reference example A:
Fill weight = 1,5 [kg/m]
Unsupported length FLB = 2,2 m
Travel = 4,4 m
