Installation and Operating Instructions for
Brake Caliper DH 010 FPM
spring activated, pneumatically released
5.1 Installation
The brake caliper should be mounted to stabile, vibration-free machine components in order to
ensure noise-free, non-screech.
During installation, it is essential to ensure that brake pads are centred and in full contact with
the brake disc (the midlines of the brake arm must point to the midpoint of the brake disc.).
Maximum permissible lateral brake disc wobble is 0.2 mm. Greater wobble may cause rattling
and shaking of the brake unit.
The brake caliper is mounted to the machine component with using 2 M8 bolts (strength class 8.8).
5.2 Compressed air connection
The system requires pressure of at least 5 bar; maximum permissible pressure is 8 bar.
The connection thread on the cylinder block is M5. The actual screw depth is 4.5 mm.
The brake caliper is factory-delivered with an 360° swiveling L-shaped hose connector.
Two versions are available:
LCS-M5-PK4 (old version) made of blue plastic with a metal screw plug and a red clamping
ring. This version is connected by means of a PU, PL or PP plastic hose with an outside
diameter of 6 mm (e.g. plastic hose PU-4, part no. 6204, blue, or part no. 5733, black,
manufactured by FESTO AG & Co, D-73726 Esslingen).
QSML-M5-6 (new version) made of black plastic with a metal screw plug and a blue clamping
element. This version is connected by means of a PUN or PAN plastic hose with an outside
diameter of 6mm (e.g. plastic hose PUN-6x1-BL, part no. 159664, blue, or part no.159665
Compressed air must be filtered to remove all dirt, pipe chips, rust and condensation. Purified air
must then be enriched with a fine oil mist injected by a standard, commercially available
conditioning unit. The quantity of oil added depends on the nominal air flow rate in l/min and is
specified by the manufacturer of the conditioning unit.
The following types of oil are recommended for conditioning units:
Suitable types of oil Viscosyty at 20° C (mm²/s)
Avia Avilub RSL 3 34
BP Energol HLP 40 27
ESSO Spinesso 34 23
Shell Tellus Öl C 10 22
Mobil VAC HLP 9 25,2
Maximum air consumption per braking operations is approx. 10 cm³ .
5.3 Adjustment the braking and/or holding force
The gap must be reset: - during initial installation
- when brake pad wear has been detected
- following brake pad replacement
Pressurize the brake caliper with 5 to 6 bar air pressure.
Note:
Subsequent operating pressure must be equal to or greater than this initial setup pressure, as
otherwise the brake caliper will not open completely during normal operation, which can result in
brake pad rubbing.
