Attention!
If the brake is used as parking brake, the brake torques specified are not met.
Reductions of up to 50% of the braking torques are possible.
Attention!
If the brake cannot be run in, the braking torques listed in our publication no. 46
cannot be achieved. Reductions of up to 50% are possible.
Attention!
If the grub screw pos. 44 is provided with sealing wax at the factory, the clamp-
ing force on the brake must not be adjusted by the customer!
The braking force is adjusted to the maximum braking force. If the braking force should be re-
duced, the clamping force can be reduced by reducing the pretension of the spring. Therefore
you have to loosen the threaded pin Pos. 44 of the spring compression nut Pos. 43. With the
spring compression nut you can adjust the distance S (see Fig. 8.5) according to the values in
table 8.4. If you reduce the clamping force the reaction time of the brake will increase. After the
adjustment, lock the spring compression nut with the threaded pin.

1)
Braking force and braking torque is calculated with a theoretical friction coefficient of 0,4 and 100%
clamping force.

= Outer diameter of the brake disc in mm.
3)
Reduction of clamping force increases noise and wear of mechanical parts of the brake.
