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!
Environmental considerations:
Storage temperature: –20°C to +70°C
Relative humidity:
5% to 85%
Linear Unit LRE 8 D14 ZU 40 R25 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
chemical 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 LRE 8 D14 ZU 40 R25 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.
Fundamentally, a Linear Unit converts a rotary motion into a translational
motion.
A Linear Unit is made up of:
▪
Guide
▪
Drive
▪
Support profile
These components are picked for assembly and assembled in part or in full,
depending on customer wishes.
