Assembly/disassembly as individual components
Before you can assemble your new linear units you must remove any securing devices used in their
transport.
4.1
Mounting on the linear guide rail
You have several options for mounting the components individually:
A) Free-standing linear unit
You can place the linear unit on a rack, work table or any other suitable, i.e. sturdy base.
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 profiles for mounting the linear units on your rack have several T-nuts on the underside.
These are for mounting the threaded rails or slide nuts (accessories). Use M6 securing screws to
mount the linear units onto your rack from below.
Make sure the mounting surfaces are sufficiently clean.
The aluminium profiles used are extrusion profiles which can deviate in terms of their straightness and
distortions as a result of the manufacturing process.
The deviation tolerance is set down in DIN EN 12020-2.
Isel linear units are plane-milled and any deviations generally fall below the tolerances.
However, to achieve the desired guide accuracies and running performance, the axle system must
either be laid out over an appropriately flat surface or arranged over levelling plates. This achieves
tolerances of minimal 0.1 mm/1,000 mm.
C) Foot mounting
If it is not possible or too costly to mount the linear units from below, they can be mounted
from above, using special mounting rails(accessories) or appropriate adapter plates.
The relevant adapters must be fixed to the linear guide rails via slide nuts or threaded rails and the
units then mounted completely from above.
Make sure the fixing surfaces are sufficiently clean and sufficiently level.
