We recommend that Treotham calculate every long travel application (gliding) for you. Treotham offers a free design service.
For long travels, the upper run of the igus® e-chains® rests on the lower run. The upper run of the chain glides partly on the lower run and partly on a glide bar. The diagram below shows this. For lateral guidance, a guide trough is necessary. If the stationary mounting bracket and the fixed end of the cables and hoses can be placed in the centre, the e-chain® length is calculated as follows: Lk = s/2 + K2
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 (lowered moving end).
