Series R68 Classic

DISCONTINUED MODEL
For new designs, we recommend the improved e-chain® Series E2 tubes, R68 new

Series R68 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. Thanks for your understanding
Series R68 new - Tube, openable along the outer radius

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 R68 - Tube, openable along the outer radius

1. Fully enclosed - very good protection for cables and hoses, even against hot swarf
2. Small pitch for quiet, smooth running
3. Lids removable along the outer radius

For E2 R Series R68 new Available inner widths Bi: 75 to 175 mm
Available bend radii R: 100 to 300 mm
Pitch: 36 mm per link = 28 links/m

When to use series R68 E2 tubes

If very quiet running is required
At particularly high speeds
For high requirements for chip tightness

When not to use series R68 E2 tubes

If a particularly cost-effective solution is required
Series R167
When no swarf protection is required
E20000 medium Series 3400
For new designs
Series R68 New

* The required clearance height is HF = H + 40 mm (at 2.5 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: 36 mm
Chain links per m: 28
Travel: S
Tube 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

"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. 93.30, guide trough with glide bars part no. 93.31, assembly sets as butt connectors part no. 93.50. 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.
