Gliding | Long travels

Gliding applications principle
For long travels, the upper run of the igus ®
Recommended ratio of e-chains ® rests on the lower run. The upper run of
inner width Bi to bend the chain glides partly on the lower run and partly
radius R on a glide bar. The diagram below shows this.
The minimum inner width of For lateral guidance, a guide trough is necessary.

For particularly large bend the centre, the e-chain ® length is calculated as
radii on long travels, please follows: .
consult igus ® . Depending on the technical data and the selected
e-chain ® , the mounting point of the moving end
of the e-chain ® must be lowered on some units
