CONTAINER
HANDLING
T h i s d i m e n s i o n a l
compatibility ensures
a very easy conversion
from elastic to gear
c o u p l i n g s . F o r a
conversion it’s only
required to take out
the claw r ings and
elastic part from the
e x i s t i n g c o u p l i n g
and insert the S-NX
conversion kit (geared
p a r t s ) . T h i s wo r k
takes not more time
than just replacing
the elastic r ing as
such. The gear- and
motor-side hubs and
the brake disc can be
kept in place and a
re-alignment of the
drive is not required.
M o r e o v e r ,
considerable efforts
have been spent to
improve the gearcoupling
design as
s u c h . T h e g e a re d
par t of the S-NX
( m a d e o f h i g h -
grade forged steel)
is fully encapsulated
and provided by the
manufacturer, with
a long-life g rease
filling. Re-greasing is
not required (similar
to encapsulated ball
b e a r i n g s ) a n d n o
external seals needed
to be fitted dur ing
installation. And just
in case: all parts can,
of course, be replaced
later without moving
the drive or gearbox.
