Installation notes
Pay close attention that the contact surfaces fixed to the carriage have
a good surface finish (e.g. machined surface), so that the carriage
does not bind. If a carriage is removed from the rail, the end with the
cover which has a part number located at the bottom right, must be
pushed onto the rail first. Rails and plastic carriages are provided with
a mark, ensuring correct orientation of the carriage.
Mounting instructions
When designing systems with 2 parallel rails, one side must be used
with floating bearings. For each mounting version, there is a
recommended fixed floating bearing solution. This installation method
prevents a binding or a locking of the guide when there are parallelism
errors between the rails. The floating bearing is created by the removal
of the static sliding elements. The maximum compensation of parallelism
errors between the mounted rails is 0.5 mm. In the installation, care
must be taken that the floating bearing has equal play in both directions.
You can see our recommended design of the fixed floating bearing
system in the adjacent drawings. The mounting surfaces for the rails
and guide carriages should have a very flat surface (e.g. machined
surface), in order to prevent binding in the system. Variations in the
connection surfaces can also be compensated up to a certain amount
(0.5 mm) by a larger adjusted clearance. The clearance adjustment
is only effective without load. Please contact our technical experts if
you have any questions on the engineering design and/or installation.
Installation of the profile rails
The profile rails will receive all the loads and torques of the linear guide
system. The performance of the linear guide system is dependent on
the installation method – especially for systems with parallel rails.
Observe the following guidelines during installation.
All surfaces must be clean prior to installation. The profile rails are
mounted along a leading edge or aligned with another reference line;
then the mounting screws are applied by hand.
The screws are tightened in the following steps:
1 All screws first at 30% MA (MA = final torque)
2 Then each second screw at 70% MA
3 The remaining screws at 70% MA
4 Every other screw at 100 % MA
5 The remaining screws at 100 % MA
The following values represent recommended
torque (MA) for the different rail sizes:
TS-01-15: MA = 10 Nm
TS-01-20:
TS-01-25:
TS-01-30:
MA = 14 Nm
MA = 16 Nm
MA = 35 Nm
Use of a straight edge
Place the straight edge between two profile rails, align with a spacer
gauge on the reference rail and affix, then align the profile rail of the
opposing side with the spacer gauge on the straight edge
Adjusting the clearance: DryLin ® T
DryLin ® T is delivered ready for installation. Clearance of the carriage
is adjusted at the factory. The preadjustment is determined by the
acting forces on each individual system. If you have special
requirements, please indicate in your order whether particularly limited
or extended bearing clearance is required. If necessary, clearance of
the DryLin ® T linear guide system can be readjusted. This should
always take place when there is no load on the carriage.

After removing the protective cover,
loosen the locknuts – Width across flats:
SW 5 for TW-01-15 and for TW-01-20
SW 7 for TW-01-25 and for TW-01-30
Adjust the bearing clearance for the 3 guide
2 points with an Allen key – Allen key size:
1.5 mm for TW-01-15 and for TW-01-20
2.0 mm for TW-01-25 and for TW-01-30
Check the clearance of the carriage after adjusting the 3 levels.
3 If it is sufficient, tighten the locknuts and put on the cover.
There is a danger that excessive reduction of the clearances
4 can seize the gliding elements and that the clearance cannot
be reset simply by loosening the adjustment screws. The
gliding elements are then released by pressing the reset button
on the opposite side. Press hard against the readjusting
spring. You must have already loosened the respective
adjustment screws. Use the correct sizepin for this purpose:
2.5 mm for TW-01-20 and TW-01-15
3.0 mm for TW-01-25
3.0 mm for TW-01-30
Adjusting the clearance: DryLin ® T Automatic
The DryLin ® T Automatic series offers you an automatic adjustment
of the clearance. A readjustment can take place automatically in steps
of 0.1 mm. Springs tighten the regulating wedge immediately as soon
as the clearance is bigger than 0.1 mm and the system is unloaded.

The system will be delivered with 3 spanners which are already
plugged in. They are necessary for mounting the carriage onto
the rail. In case these spanners are removed they need to be
replugged into the openings and turned right by 90°.
When the carriage is on the rail, loosen the spanners by
2 turning them left 90° and remove them. The clearance will be
adjusted automatically.
Check the clearance of the carriage. A fine adjusting can be done
3 at this point.
You can remove the carriage at any time. In order to do so,
4 simply plug the spanners back into the openings (see step 1).
