3 MECHANICAL INSTALLATION:
3.1 Before starting:
Check that the brake is suitable for the machine. Check the characteristics plate check that both the
operating voltage and the braking torque correspond to the requirements for the installation.
3.2 Tools:
3.3 Installation:
1º- Check the position is perpendicular between the axle and the support surface of the brake.
Danger: Do not hang the brake from the cables: this may lead to damage to the
brake and/or the brake falling.
2º- Degrease the friction material support surfaces.
Danger: Deficient cleaning of the braking surfaces may lead to a decrease in the
brake torque.
We recommend the use of Loctite® 7063 or similar. Procedure: Apply the spray on the two support
sides of the brake disc. Clean both sides with a clean cloth. Repeat the process until no dirt shows
on the cloth.
3º- Place the disc in the machine axle groove. Remove the film protection from the disc. Move the
disc to its end position in contact with the braking surface of the machine. The adjustment must slide
and not be loose.
Danger if loose.
The disc brakes must not be contaminated.

4º- Position the brake in the machine and clamp it to it by tightening the corresponding fixing screws.
You should guarantee the correct concentricity between the machine axle and the central gap of the
brake (in which the encoder is usually clamped).
3.4 Screw tightening torques:
Screw tightening torques must be respected: insufficient tightening may lead to the separation hubs
being displaced and the corresponding transmission of the braking torque to the fixing screws, with
the risk of them shearing. An excessive tightening may also jeopardise the safety of the brake. The
use of torque wrenches is recommended.
