Environmental considerations:
Storage temperature: –20°C to +70°C
Relative humidity:
5% to 85%
Linear Unit LRE is intended as a permanent fixture to be used in an area that is
protected from the weather.
The area should be free from mould and fungus and show no traces of rodents
or other pests.
Do not install or use in close proximity to industrial plants that produce chemi-
cal emissions.
Do not install or use near sources of sand or dust.
Do not install or use in an area that is regularly exposed to high-energy surges
such as those caused by presses or heavy machinery, for example.
In case of doubt regarding resistance to certain chemicals such as test oil,
alloyed oils, aggressive cleaning substances, solvents or brake fluid, we advise
that you consult your specialist representative.
Consult the manufacturer if using in very salty air. Deflection in the linear axis of
the LRE should not exceed 1 mm over an axis of 1000 mm. In scenarios where
high demands are placed on the system dynamics, supports should be added
every 300 mm to 600 mm. These supports must not affect the Reverse Units.
Operating parameters
The safety distance S is a reserve distance to accommodate tolerances
and carriage overtravel under high loads and accelerations at the reversal
point. It must be factored into the equation depending on the capabilities of the
drive and Controller, but in any event should not be smaller than shown!
Linear Unit LRE 8 D14 80x40 KU 80 is generally constructed from Line 8
profiles that have been cut to size and various assemblies. Before starting
installation work, it is important to check that all parts are present.
The maximum possible drive torque is: T
D
= 20 Nm
The frictional torque or starting torque without load for the Linear Unit,
depending on the Chain Reverse Units and Chain tension, is: T
F
= 1 Nm
