11. Repair
The lateral rollers (side rollers) are easy to access and can be exchanged with-
out removing the carriage. The upper and lower rollers can only be exchanged
after the carriage has been partially or fully removed, depending on the instal-
lation position of the linear unit.
The auxiliary device (>>> Fig. 11-6) is used to extend the track to the side. It
is fastened to the track. For the opposite track, the auxiliary device can be con-
verted to a mirror-image part. To exchange the rollers, the carriage concerned
is moved onto the auxiliary device so that the rollers destined for removal are
free.
If the carriage is on the auxiliary device, it is held by nine rollers on the tracks
and the auxiliary device.
If the carriage is on the auxiliary device, the remaining three rollers are not
guided by a track. These three rollers are freely accessible for exchange work.
