3.
Place the screw-in hubs (Fig. 26/2) on the timing belt shafts
(Fig. 26/1) of both linear units.
4.
Tighten 4 screws each (Fig. 26/3), alternating diagonally:
Size
Screw size
Tightening torque [Nm]
40
M4
4.2
60, 80, 120 M8

5.
Insert gear rings (Fig. 26/4) into the screw-in hubs.
6.
Loosely slide the following components onto the steel tube
(Fig. 27/4) one after the other:
n
2 clamping hubs (Fig. 27/1)
n
Protective tube (Fig. 27/2)
n
7.
Position the steel tube (Fig. 27/4) with the loose components
between the screw-in hubs of both linear units.
8.
Slide clamping hubs (Fig. 28/2) into the screw-in hubs
Ensure that the clamping hubs on the steel
tube engage correctly in the screw-in hubs
on the linear units.
To reach the clamping hubs, move the pro-
tective tube (Fig. 28/4) on the steel tube.
9.
Tighten the screw (Fig. 28/3) on each clamping hub.
