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. Thank you for your understanding
Series R68 – Tube, opens along the outer radius

Here you can configure your Energy Chain System® individually. All entries will be copied to the Bill of Materials shown at the bottom of this page.

Series R 68 - openable in the outer radius

1. Fully enclosed - very good protection of cables and hoses, also against hot chips
2. Small divisions for quiet, smooth operation
3. Removable external-radius lid

Inner widths Bi: 2.95 up to 6.89 (75 - 175 mm)
Bending radii R: 3.94 up to 11.81 (100 - 300 mm)
Pitch: 1.42 (36 mm) per link = 9 links/ft (28/m)

When to use Series R68 "E2 tubes"

When particularly smooth operation is required
In the case of particularly high speeds
In the case of high requirements concerning protection against chips

When not to use Series R68 "E2 tubes"

When a particularly economical solution is of prime importance
Series R167
When no protection against chips is required
E2 medium - Series 340
For new structures
Series R68, new

Aluminum "Super Trough"- the igus® standard

The Aluminum "SuperTrough" is a modular guide trough system for long travels (when E-Chains® glide on themselves, as per sketch). Aluminum "SuperTrough" is available in low cost "basic versions" and can be upgraded for heavy duty applications. This universal usage makes it the igus® recommended new standard trough system.

Multiple fastening options with heavy duty brackets, bottom clamps and interface connectors
Side-mount glide strips for wear protection in high-speed
Corrosion proof through seawater resistant aluminium
Flexible assembly - connects with underground, independent from profile length and location of trough section interfaces
