Series 20 Classic

DISCONTINUED MODEL
For new constructions, we recommend the technically improved e-chain® Series 2500 from the igus® E20000 product range.
Secure hold of the crossbars, improved opening principle, longer unsupported lengths, same dimensions

Series 20 is available from stock in limited numbers. Product support and storage are limited as of 2012. For questions, please refer to your igus® contact person. Thank you for your understanding
to the E2/000 Serise 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.

* The required clearance height is HF = H + 25 mm (at 1.5 kg/m fill weight), which should be observed in all types of applications. 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

The unsupported length depends on 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

Separators are the only option to separate the interior of the non-openable chain of the type 20. Spacers can be used to adjust the space between two crossbars to a certain width. This function is used primarily for side-mounted chains.

Guide troughs

Steel guide troughs

1. Guide trough (blue)
2. Glide bar (black)
3. Installation set (red)
4. Individual attachment without C-profile
5. Profile rail length

Guide troughs are used for applications where the upper run of the e-chain® glides on the lower run. When using the igus® guide trough made of steel, the following components are required. Guide trough without glide bars part no. 92.30, guide trough with glide bars part no. 92.31, assembly sets as butt connectors part no. 92.50. XX
.XX indicates the length of the C-profiles on which the guide trough will be mounted. The standard length of the trough parts and glide bars is 2m. The required length of guide trough is determined by the travel length.
