A. Installation of plastic slide rail and support rail
About slide rail
The slide rail is attached to the sides of the conveyor
beam to reduce chain friction where the chain w ould otherwise be in direct contact with the beam profile. It is v ery
im
portant that the slide rail is installed properly, so that
the chain can run without disruption.
When the conveyor is to be mounted high above
g
round leve l, it might be easier to mount the slide rail onto
a convey or section while the conve yor beam is still on the
floor. If doing so, leave an extra end, approximately
300 mm longer than the beam, so that it can be cut off
a
nd adjusted when the beam is finally installed.
Characteristics
Slide rails are available in several materials, each with
ferent characteristics:
dif
The coefficient of friction is normally closer to the lower
v
alue at startup of a new conveyor. It will increase as the
contact surfaces are wearing in. Lubricants will reduce
the coefficient of friction.
Considerations when selecting slide rail
Each of the slide rails has its own characteristics and is
suitable for different types of applications.
Slide rails made of HDPE or PA-PE are suitable for
mo
st standard applications. PA-PE has higher wear
resistance but should not be used in wet environments.
In environments where high resistance to chemicals
is
important, PVDF slide rails are recommended.
Hardened steel slide rails in combination
slide rails in bends can be a good combination where
larger particles such as chip occur.
UHMW-PE has the highest wear resistance and can
be
recommended in applications with accumulation,
transport of heavy parts, high speed, abrasive particles
or requirements on low dust generation.
Horizontal plain bends
The contact pressure between the chain and the slide r ail
is v
ery high in the inner bend of horizontal plain bends. It
is important to use the PVDF slide at this location if the
speed is high as there will be increased temperatures
that may cause melting of other slide r ails. This, howe ver ,
will result in somewhat higher wear on the chain.

Attaching the slide rail in straight sections
Tools required
Slide rail installation tool:
XS-XL X85,
X180/X300
XLMR 140 XBMR 170 XMMR 140 XHMR 200 XKMR 200
Procedure
1 Start at an idler end unit.
Separate the top and bot
tom flange of the slide rail
at the end of the rail and
press it into place.
2 Make sure that you
mount the slide rail so
that it snaps on to the
beam. The different typ es
of slide rail do not look
alike, so check which
flange should be on top.
3 Use the slide rail mount-
ing tool to press the slide
rail into place. One end of
the tool is used when
slide rail is mounted onto
only one side of the
beam, and the other end
is used when you mount
slide rail onto the second
side.
4 Do not forget to mount
slide rails both under
neath and on the upper
side of the beam (unless
top running chain only)

Joining slide rails
Tools required
Cutting pliers
Procedure
1 Cut both slide rail ends in
a 45° angle. The begin
ning of a new slide rail
section (in the direction of
travel) m ust be cut back a
small angle.
2 Allow a space of approxi-
mately 10 mm between
two slide rail ends. The
arrow indicates travel
direction.
3 Do not place two slide rail
joints opposite each
other. Ma ke sure there is
a distance of at least
100
mm between them to
make the chain run
smoother.
This does not apply to slide rail that begin s by an idler
unit or after a drive unit, where joints are alw ays par
allel.
Comments
• Try to let the slide rail run in as many continuous
lengths as possible, except in circumstances stated
below:
• It is recommended to use short slide rails (2–3 m)
where chemicals may have an effect on the slide rail
composition.
• It is important to cut the slide rail and allow f or elongation in high load areas. Cutting is required in wheel
bends (see below), by idler units and where the con
veyor will be heavily loaded, especially by the drive
units. This prevents the slide rail from stretching out
and entering into the drive unit, which may block the
chain.
• Never join slide rail in horizontal or vertical bends,
since forces are higher on the slide rail in these sec
tions. Instead, place the joint before the bend.
• Avoid joining slide r ails on top of conveyor beam
joints.
