2 Precautions and restrictions on use

2.1 Restrictions on use

These clutches are designed solely to run

These clutches are designed to run dry. Any oily

material alters their performance.

on a horizontal shaft. Ask our technical
department about other positions.

Exceeding the maximum rotation speed given in

the catalogue invalidates the warranty.

2.2 Precautions and safety measures

During the maintenance period make sure

that the moving parts of the machine are
stationary and that there is no risk of start-up.
All intervention have to be made by qualified
personnel, owning this manual.

In cases where two coaxial shafts are fitted, the

maximum authorised setover is 0,05 mm. The
angular misalignment should not exceed 0,1
mm over a length of 100 mm. If these values
cannot be attained, we recommend that an
elastic coupling is fitted between the drive and
receiving parts.

Any modification made to the brake without

the express authorisation of a representative of

Warner Electric, in the same way than any use
out of the contrac tual specifications accepted

by “Warner Electric”, will result in the warranty
being invalidated and Warner Electric will
no longer be liable in any way with regard to
conformity.

3 Installation

3.1 Transport / storage

These units are supplied as standard in

packaging guaranteeing protection for a period
of 6 months by land or air transport, or after
transport by ship to neighbouring continents
(without crossing the tropics).

3.2 Handling

The clutch is supplied pre-assembled with the

driving flange not fixed.

Avoid any impact on the units so not to alter

their performance.

3.3 Mise en place

The hub (515) is normally supplied at tolerances

H7 for the bote and P9 for the width of the
keyway (In accordance with NF E 22-175/DIN
6885/BS 4235/ISO R773).

Do not forget to secure the bolts fixing the

driving flange (529) with Loctite 243 or an
equivalent type of product and tighten them to
torque.

Never directly strike the cylinder (401), closing

flange (408), or hub (515), use a soft alloy block
or drift between these parts and the fitting
device provided.

It is essential to comply with the length

dimension “ L ± 0,5 “ (see table 1) in order to
prevent any risk of contact between the drive
flange (529) and the hub (515).

4 Maintenance

4.1 Maintenance

P130, VAR00/02 series clutches only require low

maintenance because wear in the disc set is
automatically compensated for by movement in
the piston, within the limits of its travel.

It is however necessary to:

• Regularly check the seal of the pressure
chamber and in the event of leakage, or after 5
years use, change the seals (701, 702)

• Check the wear on the disc set, by measuring
the travel of the piston (402), using table 2,
below and the diagrams on annex

The drive flange (529) is generally supplied at a

bore H7 but without fixing holes.

We recommend a tolerance h6 for the shaft and

an adjustment H7/f7 for he drive flange (529).

• Centre the flange (529) on the recieving part,
then fix it with bolts and lock them

• Slide the hub (515) onto the shaft (after
adjusting the keyways) by positioning the teeth
of the outer discs (302) or (305), opposite of the
hollows of the driving flange (529).

4.2 Spare Parts

5 Pneumatic Connections

All orders for spare parts must state the size

of the unit with its code number, the reference
number of the part (see appendice 1), and the
quantity of each component wanted.

4.3 Dismantling / Reassembling

During maintenance work, ensure that the

mechanism to be driven by the clutch is at
rest and that there is no risk of it being started
accidentally. Also ensure that the compressed
air is turned off.

Dismantling:

• Remove the fixing screws from the cylinder
(401) or closing flange (408)

• Remove the cylinder (401) or closing flange
(408)

• Take out the piston (402)

• Remove the worn disc set

• Fit a new disc set

Start with an outer disc (302 or 305), then an

inner disc (308), and then alternate, ending of
necessity with an outer disc.

• Change the seals (701, 702)

• Refit the piston (402)

• Refit the cylinder (401) or closing flange (408)

Take care not to damage the seals while

reassembling

• Replace the cylinder (401) or closing flange
(408 fixing screws, tighten them to the torque
shown in table 3, below and secure them with
Loctite 243 or an equivalent type of product

5.1 Important Recommendations

Ensure that working pressures are complied

with, to get the nominal performance from the
equipment.

Do not exceed the maximum pressures
(see table 1).

These clutches should be supplied with filtered,

oiled air.
