Locking Ring (not self-centering)


Inch sizes available upon request.
Consists of two cone rings and
must be quipped with a fastening
flange, usually manufactured by
the Customer. The number of
locking screws depends on the
torque to be transmitted. It is not
self-centering.
Locking Ring
requires very small axial
installation dimension. Up to 4
units can be arranged behind each
other allowing high torques to be
transmitted. Available for shaft

Self Locking Ring Elements


Locking Ring Assembly Type 3

Locking Ring Assembly Type 3


(self-centering)
Consists of two conical pieces
and a spacer. It has minimum
overall dimensions in virtue of
the reduced thickness of the
cones; so, Locking Ring
Assembly Type 3 is suitable for
the applications where small
hubs are requested.
It is recommended for medium
torques and is self-centering.
Locking Ring Assembly Type 3
guarantees a very precise axial
positioning, as no axial
displacement of the hub occurs
during the assembly operation.
Available for shaft diameters
from 6 to 130 mm.

Locking Ring Assembly Type 5A


(self-centering)
Consists of one inside and one
outside cone ring, which are joined
by a set of screws. It is suitable for
high torques and is self-centering.
It is not suitable for applications
which request a very precise axial
positioning due to a small axial
displacement of the hub during
the assembly operation. Available
for shaft diameters from 20 to 180
mm.

Locking Ring Assembly Type 5B

Locking Ring Assembly Type 5B


(self-centering)
Consists of one inside and one
outside cone ring joined together
by means of a set of screws and
a stop ring. It is recommended for
medium torgues and is selfcentering. Locking Ring
Assembly Type 5B permits a high
precision axial positioning, as no
axial displacement of the hub
occurs during the assembly
operation. Available for shaft
diameters from 20 to 180 mm.

Consists of one inside and one
outside cone ring which are
joined by a set of screws. It has
a very small axial dimension and
is self-centering. It is not
suitable for applications which
request a very precise axial
positioning due to a small axial
displacement of the hub during
the assembly operation.
Locking Ring Assembly Type 6 is
suitable for applications with
medium torques. Available for
shaft diameters from 20 to 200

Locking Ring Assembly Type 9


(notself-centering)
Consists of two cone rings, joined
through a lock nut and a tab
washer. In virtue of the simple
design, very fast assembly/
disassembly is allowed. Locking
Ring Assembly Type 9 is suitable
for applications with small-medium
torques. Available for shaft
diameters from 14 to 70 mm.
