Series 255

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 255 每 chain, openable along the outer radius

1. Openable left and right, accessible from above
2. Lateral gliding surfaces for side-mounted operation
3. Large pins - long service life
4. Chamfered opening - easy assembly
5. Small pitch for quiet, smooth running
6. Integrated strain relief option
7. Cable-friendly interior separation
8. Dirt-repelling outer contour
9. Modular interior separation

Available inner widths Bi: 38 to 103 mm
Available bending radii R: 55 to 250 mm
Pitch: 27,8 mm per link = 36 links/m

Series 255 is suitable for the following types of applications:

Vertical: Hanging applications ≒ 40m, standing applications ≒ 3,0m
Horizontal: Unsupported applications ≒ 1.8m, gliding applications ≒ 100m
Circular movement: Rotating applications possible, may require machining (machining rework is always required from rotation angles of 180～)

When to use Series 255

When a medium-sized, strong e-chain? with smaller pitch for low noise, quiet run and 24?mm interior height is required
If an inner width up to 103mm is required
For unsupported lengths up to 1.8m and fill weights up to 2.0kg/m
For travel lengths up to 100m
If opening the crossbars from either left or right is required

When not to use Series 255

If each link should openable from both sides
System E4.1, Series E4.21
If maximum stability is required
System E4.1 Series E4.21
For very easy applications
easy chain?, E200

* 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.

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

Reference example A:
fill weight = 2 [kg/m]
unsupported length FLB = 1.2 m
travel = 2.4 m

Option 1: Standard
As a standard feature, igus? separators should be fitted every 2nd chain link!

Standard slotted separator 2551 and slotted separator 2553
Vertical separation in e-chains?. The slot allows basic vertical/horizontal shelving arrangements. (The retrofit you want to do determines which separator to use)

Full-width shelf 220.X
Recommended if many small cables with similar or same diameters are used. For a continuous interior separation. Full-width shelves can be arranged in steps of 5 mm on 3 levels.

Shelf 2200.X
In the case of cables with different diameters, shelves can be used at different heights. They can be arranged in steps of 5 mm on 3 levels.

"Super-aluminium" trough - the igus? standard for guide troughs

The "Super-aluminium" trough is a modular system of guide troughs for long travels (where e-chains? glide on each other). The basic "Super-aluminium" trough is available in simple, cost-effective "basic designs" and can be expanded for sophisticated plant construction. This universal usability makes it the recommended igus? standard for guide troughs.

Various mounting options with bracket, clamping shoe, interface connectors
Side-mounted glide strips for wear protection on high-speed applications
Corrosion-resistant due to seawater-resistant aluminium
Flexible assembly - fastening on substructure independent of profile lengths and butt joints

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.
