Installation Conditions

Before mounting the brake, please observe:
 Axial run-out deviation of the brake disk: max. 0.25 mm
Due to axial run-out deviations or tilting
between the brake and the brake disk, the
brake disk may rub against the friction linings.
 Brake disk surface quality (friction surfaces): Ra = 3.2 µm
 Brake disk material: steel or cast iron.
 For brake disk width K, see Table 4.
 Please keep to the distances I or l1 (Figs. 6 or 9 / Table 2)
between the screw-on surface and the brake disk.
(not valid for Type 894._ _ _.0 _).
 Brake disk deformation or bearing backlash must not
influence the set air gap.
 In order to guarantee rub-free operation, a perpendicularity
of 0.04 mm to the brake disk must be maintained on guide
bolt 1 or on the bore axes.
 The screw-on surface in the  50 mm range (Fig. 14) must
be 0.04 mm parallel to the brake disk when the guide bolts
are bolted (Type 894._ _ _.1/2 _).
 Keep the brake surfaces and the friction linings grease-free.
 Please ensure a suitable protective cover on the open brake.
 For mounting using guide bolts which are to be pressed in
(Type 894._ _ _.3/4 _), please produce the adaptor bores as
follows:
 Bore for guide bolt 1:
Ø G3 P7 with surface quality Ra 0.8.
 Bore for guide bolt 2:
Ø G3 H7 with surface quality Ra 0.8.
 The distance dimension "A" of the bores for the guide
bolts must have a tolerance of ±0.1 mm.
