Series 250 Classic

DISCONTINUED MODEL
For new designs, we recommend the improved e-chain® series 2500 from the igus® E2/000 range.
Secure support of the opening crossbars, improved opening mechanism, larger unsupported lengths, identical dimensions

Series 250 is available from stock in limited numbers. For questions, please refer to your igus® contact person. Thank you for your understanding
regarding the E2/000 Series 2500

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 250 – chain, snap-open along outer radius

1.Large pins; long service life
2.Cable-friendly interior
3.Dirt-repellent
4,240 snap-open on the inside / 250 snap-open on the outside
5.integral strain relief
6.Chamfered opening; easy assembly
7.Reinforced stop-dogs
8.Snap-open along both sides

Available inner widths Bi: 25 to 125 mm
Available bend radii R: 55 to 250 mm
Pitch: 46 mm/link = 22 links/m

When to use Series 250

Can be snap-opened along the outer radius
Integrated strain relief required in the connection area
Modular interior separation
Long service life
Easy assembly

When not to use Series 250

If each link should snap-open along both sides
System E4, Series 220, etc.
If maximum stability is required
System E4, Series 220, etc.
If chip protection is required
energy tube E2, R48
For very easy applications
easy chain®, E200

* The required clearance height is HF = H + 25 mm (with 1.5 kg/m fill weight), this should be taken into account for all application types. Please contact us if you have particularly confined space requirements.
** The calculated length corresponds to the chain length without mounting brackets.

A=Moving end, B=Fixed end
Pitch: 46 mm
Chain links per m: 22
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
