## 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 […]
