How do I calculate the chain length for my supply?

Phillip Hagedorn | 7. July 2019

The chain length calculation (only in German) is made for an unsupported or gliding application. Unsupported: If the supply point is outside the centre, the formula for calculating the chain length is as follows: K = π x R + (2 x T) Lk = length of the e-chain S = length of travel S/2 […]

What does clearance height HF mean?

Phillip Hagedorn | 7. July 2019

The clearance height HF indicates the required installation height. All igus e-chain series are manufactured with pretension. In the clearance height section, you will find the measurement HF, which specifies the necessary clearance height, taking the pretension into account. HF = H + X HF = Required clearance height H = Nominal clearance height X […]

How long can my e-chain be unsupported?

Phillip Hagedorn | 7. July 2019

The maximum unsupported length of an e-chain depends on the selected series and the additional weight. You can find whether a combination of selected e-chain and additional weight will work can be found in the FLG/FLB graph belonging to the series. Here is an example for the E4.42. series: If the additional load is 10 […]

What is the difference between unsupported with straight upper run and unsupported with permitted sag?

Phillip Hagedorn | 7. July 2019

Since the e-chain is dependent on fill weight, we distinguish between three stages of unsupported length: 01) Unsupported length – straight FLG The e-chain is in the range FLG if its upper run is either still pretensioned, straight or has a maximum sag of half a chain link height. Installing in FLG is always recommended. […]
