Assembly / disassembly as individual components
You have several options for mounting the components individually:
A: Freestanding
B: Rack assembly
A) Freestanding installation of the linear unit
You can place the linear unit on a rack, a worktable or any other suitable, i.e. load-bearing support.
Choose the location carefully so that the product cannot fall or be knocked over by any
impact or tug on the cables.
B) Rack mounting (recommended)
The shaft housing sections have a number of T-grooves on the underside for mounting linear units on
your frame. These are used to house threaded rails or sliding nuts (accessories). Use M6 fastening
screws to mount linear units on your rack from below.
As the topmost picture shows, you can also screw on the linear units LEZ 2 and LEZ 9 from above.
Make sure the mounting surfaces are sufficiently clean.
The aluminium sections used are extruded sections which, owing to the manufacturing process, are
sometimes not completely straight or are twisted.
The tolerances for this deviation are laid down in DIN EN 12020-2.
isel linear units are plane milled and are therefore usually within these tolerances.
To achieve the desired guide accuracies and running, however, the axis system must be tensioned on
an appropriately accurate surface or aligned using levelling plates. This achievestolerances of minimal
0.1mm/1000 mm.
