With a mounting angle between 3-5°, the e-chain is slightly forced downward by the push/pull force. This prevents the rising up of the e-chain.
The angle of incidence of the upper run to the lower run is approximately 3-5°. This angle is also ideal for reducing wear.
If the upper run is installed in parallel directly onto the lower run, the upper run can rise due to the push force exerted and the e-chain arches upwards. This happens at the expense of the service life of the e-chain. Therefore we recommend an installation with a downward mounting angle (3-5°).
