assembly procedures
PWX powder brakes and clutches require a few tricks to perform a correct assembly. Rather, it is
recommended that you follow each step and check for correct execution.
Mount the brake or clutch on the shaft with the key in the appropriate seat.

Assembly will be performed near the centering dimension B as per drawing. In case of flanged
mounting it is important to check that the machining on the machine shoulder complies with the
centering dimensions and tolerances for the flange dimension B **. In case of assembly with anti-
rotation arm, the coupling flange of the arm to the brake must be suitably machined and fixed.
IMPORTANT: Since the brake (clutch) is symmetrical, dimension B in the drawing can be found in
both parts of the product. However, one of these faces has the coil terminals which must NEVER
be mounted towards the machine shoulder or otherwise they could short-circuit making the
brake unusable. It is therefore very important to mount the coil terminals from the outside.
ATTENTION: In case of assembly of a clutch it will be necessary to fit a support for
the clutch brushes which must work in contact with the manifold.
** If the assembly foresees a flanging through centering, it will be necessary to verify that the
mechanical workings are carried out in tolerance so as not to axially or radially stress the brake /
clutch bearings. Even in a possible case of assembly with belt or chain transmission (reduction or
multiplication ratio), it will be necessary to avoid stressing the brake/clutch bearings. As a last
step, tighten the mounting screws indicated in the drawing.
NOTE: as regards the part relating to the electronics of the brakes (clutches), we recommend, as
mentioned above, the use of our ALPWX-5A power supply which provides greater stable electrical
control.
