Brake Installation Type 894._ _ _.0_
(Figs. page 6)
The brake is pre-assembled manufacturer-side.
Guide bolt 1 (Items 11 / 11.1) must keep to a diameter
tolerance of +0.02 / -0.033 mm to the nominal dimension
and a surface quality of Ra 1.6 in the area of both bearing
bushings. In installed condition, guide bolt 1 must be 0.04
mm right-angled to the brake disk.
Guide bolt 2 (Item 12 / 12.1) must be 0.6 – 1.0 mm smaller
in the bearing bushing 1 (Item 3.1 / Fig. 4) area than the
bore nominal dimension in the bearing bushing, so that no
guide bolt tension can develop due to production and
installation tolerances and warmth expansion. In the
bearing bushing 2 (Item 3.2 / Fig. 4) area, the bolt should
be even more undersized.
The guide bolts must transmit the occurring transverse
forces safely. The stability of the attachment wall must also
be observed.
The transverse force occurs on the guide bolt of the bearing
bushing 1 (3.1). The lever arm which is responsible for the
effect on the guide bolt is Z = I1 - Z1 (Fig. 14).
After mounting the brake to the machine wall, check the
axial mobility of the brake.

1.
Screw guide bolt 1 (11) onto the machine wall.
Observe the tightening torque acc. Table 5. Secure with
Loctite 243!
2.
Insert guide bolt 2 (12) into the brake caliper (3) at the back
of the brake.
3.
Release the brake mechanically (if necessary using a
suitable device).
4.
Push the released brake over guide bolt 1 (11) and slew it
over the brake disk.
5.
Insert the cap screw (13) with mounted washer (14) into
guide bolt 2 (12) and screw the brake onto the machine
wall. Observe the tightening torque acc. Table 5.
Secure with Loctite 243!
6.
Check the brake for axial smooth running on the guide
bolts!
7.
Turn the brake disk, making sure that the brake disk does
not rub.

steps 1 – 6.
2.
Guide the lever assemblies (20) outside the friction linings
over guide bolts 1 and 2 and slide them on radially.
3.
Secure the lever assemblies (20) with the cap screw (21) via
the intermediate bushing (23) onto the armature disk (2).
Please observe the tightening torque acc. Table 5!
4.
Secure the lever assemblies (20) with the cap screw (21)
and the washer (22) to the brake caliper assembly (3).
Please observe the tightening torque acc. Table 5!
5.
Check the function of the alignment mechanism:
It must be possible to turn the brake disk without rubbing
noise.

1.
Press in the guide bolt 1 (11.1) and screw it on from the
back via the thread G4 (Fig. 9) with a tightening torque of
24 Nm. Please make sure that guide bolt 1 (11.1) is in up to
its limit in the bore.
2.
Insert guide bolt 2 (12.1) into the brake caliper (3) at the
back of the brake.
3.
Release the brake mechanically (if necessary using a
suitable device).
4.
Push the released brake over guide bolt 1 (11.1) and slew it
over the brake disk.
5.
Insert guide bolt 2 (12.1) and screw it on from the back via
the thread G4 (Fig. 9) with a tightening torque of 24 Nm.
Please make sure that guide bolt 2 (12.1) is in up to its limit
in the bore.
6.
Check the brake for axial smooth running on the guide
bolts!
7.
Turn the brake disk, making sure that the brake disk does
not rub.
