6. Handling and storage
The brake weighs between 14 kg and 18 kg, depending on the version.
The brake is delivered preserved and can be stored in a closed, dry place for 12 months. Make
sure that no condensation occurs. Humid storage rooms are unsuitable. If the brake is stored for
a longer period than 12 months, as well as after each transport, the brake must be applied once
to prevent the seals and wipers from sticking together.
7. Technical requirements for save operation
Fastening the brake to stable and low-vibration machine parts will ensure quiet braking without
squeak.
8. Installing the RINGSPANN brake
8.1 General instructions regarding assembly and installation
Before installing the brake, the brake disc must be cleaned with alcohol (e.g. spirit (ethanol) or
isopropyl alcohol) or with water-based tenside solutions (soapy water or the like).
If cleaning the brake disc with a diluent, acetone or brake cleaning agent, it must be ensured that
these agents and no residues of these agents come into direct contact with the friction blocks.
This must be ensured for pure holding brakes in particular, since no dynamic braking takes place
that would remove any diluent residues from the brake disc.
Important!
Residues from oil and anti-rust agent considerably reduce the coefficient of friction
and thus also the braking and holding torque!
8.2 Installation instructions
The standard brake calliper is attached to the machine part with two M12 - 8.8 screws.
(The screws are not included in the scope of delivery)
Caution! Danger of injury!
When the brake caliper is released, the spring (5) is pretensioned. In the event that
the electromagnet is not constantly supplied with the correct power supply, parts of
the brake can suddenly move relative to each other!
Before assembly, check whether the mounting surface is level and the radial run-out between the
brake disc and mounting surface is within a tolerance of 0.3 mm.
Check that the permissible parallelism of 0.2 mm between the brake disc and the mounting
surface is not exceeded.
Check the axial movement of the brake disc. The axial movement shall not exceed ± 0,3 mm.
The maximum permissible lateral run-out of the brake disc is 0.1 mm. A greater lateral run-out
can cause the brake unit to rattle and shake.
