What do you do when your application needs
a vertical mounting ?
For this type of application, we advise you to use linear
rails. When you use telescopic slides in an upright or inclined
application, you get a loss of extension . Their ball cages
shift downwards because of gravity.
There are technical solutions ... contact
us.
Why do you choose the nitruration surface
treatment ?
For its resistance to wear: 50 HRC into
the surface. (Increased hardness of ball tracks )
For its resistance to corrosion.
When you have a high level of use, we advise you to use slides
with nitruration surface treatment.

slides
What do you do if the drawer is difficult
to move ?
Check :
The slides one by one : by manual opening
The evenness of the bearing faces on fixed and mobile parts
The parallelism of the slides on fixed and mobile parts
What do you do if the drawer is difficult
to open ?
The parallelism of the slides NB : you may put the slides back into the initial position
by opening them sharply several times in succession to regain
the extension.
What do you do if a locking drawer doesn't
lock ?
Check the bevelling of the slides; the extension
of one slide can interfere with the other.
What do you do if the lock doesn’t
engage ?
Check :
The slides one by one : by manual opening and by engaging
the lock
The bevelling of the slide: the extension of a slide can
hamper the locking of another one
What do you do if you have to mount a
drawer in an oven ?
Our standard slide in stock can withstand temperatures
up to 60°C.
For mountings in hot enclosed spaces or furnaces, the maximum
temperature we recommend is 250°C. In this case, we have
to adapt the slides , on the one hand, by removing the possible
non-metal elements, and, on the other hand, by installing,
a very free mounting allowing the expansion of the various
parts without blocking the slides. Please specify this detail when placing your order.
NB : over 150°C, zinc starts blistering and coming
off. Other solutions must be considered. Please
ask for advice.
What are the rules for a good mounting
?
Rules for a good mounting
are simple :
Use all the fixing drillings
Follow the parallelism and the bevelling of the slides
Make sure the bearing areas are even
By following these mounting rules, you will get a smooth
and regular movement of the slides. A resistance
to opening or closing indicates an incorrect mounting . In
case of incorrect mounting, the life span of the slides will
be reduced.
Can the standard extension be modified
?
The Chambrelan range is composed of 2, 3 and 4 beam slides
with any extension up to 150% of the closed length. The extension
can be increased or decreased by adapting the length of the
ball tracks.
Which kind of surface treatments are
used on Chambrelan slides ?
The standard surface treatment applied on Chambrelan slides
is zinc plated steel .
Its average endurance is 250 hours in salt spray.
Other or extra treatments can be carried out :
Organo-mineral finish on zinc plating (withstands salt spray
for 500 hours)
Standard working temperatures are between - 40° and
+ 60° . Beyond these temperatures, adaptations can be
made. Contact us.
Why does Chambrelan produce a reinforced
range ?
For extreme conditions of use, or heavy loads,
we offer you a range of reinforced slides. They can absorb
twisting effects. Reinforced slides are specially recommended
when there is a torque or when there is a mounting on a minor
axis.
What does the load capacity indicated
on technical tables mean ?
Standard load capacities are given for a pair of
slides, in the opened position, mounted oin the major
axis, with a uniformly distributed load. Be careful: with
a mounting
on the minor axis, load capacity is reduced by 40%.
What do you do if the environment is
dirty ?
Chambrelan slides come without a protection device or system
against dust, particles, etc.
There is a risk that the presence of impurities in the tracks
may rapidly cause jamming or blocking, and, thus, premature
wear of slides.
Consequently, it is important to allow the slides to be
installed in a protected area or to find the necessary protection
solutions at the time of the system design.
Do Chambrelan slides need specific maintenance
?
Chambrelan slides have been designed to function with a
minimum maintenance. Slides are lubricated in house with a
grease for intensive use. It allows an optimum life
span.
In case of hard conditions of use (corrosive environment,
intensive use ...) we advise a regular and systematic
maintenance of the slide.
What is the maximum speed of use for
Chambrelan slides ?
The
maximum speed is 0.25m per second.
Answers to requests for information on linear slides
What is the maximum length of a linear
rail ?
The maximum length of linear rails is 3 metres.
To increase this length, rails can be mounted next to each
other with a straight cut or an oblique cut.
How calculate the maximal travel within
the rail ?
It corresponds to the length of the rail, from which you
subtract the runner length and the place of the end
stop.
Are linear rail drilled ?
Drillings in linear rails are only done at a customer's
request. Fixing of linear rails is possible thanks
to standard or specific drillings. The pitch or number of
drillings can be adapted to your used conditions.
How do you to choose the right runner
for the right rail ?
Is an end stop for transportation a standing
end stop ?
Linear rails are delivered with transport
end stops to prevent the runner from leaving the rail.
Be careful: a temporary end stop can't be used as a permanent
end stop.
How many runners per rail must you put
in ?
Two
runners per linear rail are enough to withstand the
load.
In case of a lack of rigidity of the structure, you can add
some runners to the rail.
How can you choose the rail reference
adapted to your application ?
When you order, please
indicate :
The linear rail reference and the length you need.
The runner reference and how many runners you need.
