LWM/LWV rail guides
LWM/LWV rail guides enable the design
of linear guidance systems for
heavy loads with maximum stiffness.
The internal geometry is identical
with that of the Modular Range rails
of the LWRM/LWRV series. As the
same needle roller assembly is used,
the load ratings are also the same.
The external dimensions of the
LWM/ LWV rail guides, however, differ
slightly from those of the
LWRM/LWRV Modular Range dimensions.
Yet LWM/LWV rail guides find wide
application especially in machine
tools. As standard they are supplied
with attachment holes of type 15, i.e.
through hole with counterbore.
If attachment hole type 13 is ordered,
corresponding threaded inserts
are supplied along with the
guide.
For new designs the choice of
LWRM/LWRV rail guides is recommended.
These offer the advantage
of being interchangeable with other
rail guides of the Modular Range.
Needle roller assemblies for
LWM/LWV rail guides
LWHW needle roller assemblies
comprise an aluminium cage with
needle rollers arranged at right angles
to each other. The needle rollers
are retained by the cage.
End pieces for LWM/LWV rail guides
End pieces serve to prevent drift of
the cage away from the loaded zone.
LWEAM and LWEAV end pieces have
the addition of a plastic wiper with a
sealing lip that keeps the raceway
free from dirt.
All end pieces are supplied together
with attachment screws.
Rail guides with a length of more
than 1 200 mm should be made up
of sections. If, for design reasons,
one-piece rails are required, these
can be supplied to special order.
