PLE TYPES

Design guidelines
The standard type is build with stays in every second chain
link. The integrated connector makes every link in the
chain when needed to a connector (not 620) and therefore the
separate ordering and storage of end connector brackets is
not necessary.

These types are suitable for long travel, the upper strand
slides on the lower strand. For increased stability these
energy chains are also build with stays in each link. The
energy chains are fitted with sliders in the inner radius, which

have a very low coefficient of friction (µ = 0.2 to 0.25).

After reaching the wear limit, the slider can be renewed and
the energy chain will continue. Subsequent slider assembly

drilled location holes.

PLE energy chains are maintenance free. Like every

mechanical system this will depend on the ambient
conditions so wear will occur which must be observed.

In case of the energy chain has to be replaced.

For long travels or in a circular motion, the energy chains are
