The characteristics given on this website correspond to standard manufacture or usual requirements. Our position as a manufacturer enables us to offer great flexibility in order to meet the most specific requirements. So Chambrelan can easily adapt part lengths, optional lengths, drillings, diameters and hole centres, surface treatments, options and fittings for fixing.

Technical informations


This slide guide is intended for simple applications for light loads that require few cycles. it can be used as covers or guards on machine, retractable keyboards supports or drawers with small loads. Very light, it is particularly well suited for aerospace applications. It opens from both sides which makes possible transfer hatches for example.

we do not recommend vertical mounting (guillotine) for this model.

Recommended operating temperatures from -20 to 80°C.

This system cannot be flat mounted.

This product can be used as average load drawer slides, machine guard guides, telescopic rod, bar or arm, generator slide, furniture slide, extendable table slide rail, horizontal suspended guidance or in some cases as in vertical guides.


Chambrelan produces this telescopic slide using extruded aluminum profiles.

Anti-corrosion standard coating is soft anodisation.

It has straight stops when opening and closing.

It has ball cages made of stainless steel.

Its ball bearings are made of stainless steel. It is greased with a white grease.

Chambrelan is specialized in the design and manufacturing of telescopic slides and rails for industrial applications: reinforced slides, linear slide bearings rail, bearings guide, steel, aluminum or stainless steel sliders, partial, full or over extension, heavy duty industrial drawers...


Standard slides are delivered slightly greased. We use a high pressure bearing grease for steel slides and a white grease for aluminum and stainless slides. Upon request, we can use food grease (compatible clean room) a high temperature grease a teflon free grease (for spray booths...) grease free mounting (although we do not advise this option)

    A food safe grease, combined with stainless steel ball bearings, offers a cheap alternative to stainless steel slides.


    Manual lock

      It has no lock option so far.

      To lock the drawer in the center position, we have developed a slam lock. Each face of the drawer receives a handle that controls a central lockout feature. For more details: DHFDD.

      Surface treatment

      Other treatments ensuring better corrosion resistance are also available. Do not hesitate to contact us.

      This slide can be supplied with a hard anodization coating, which offers, in addition to corrosion resistance, an increased resistance to hammering of ball bearings. This option can be usefull in the case of applications subject to vibrations.

      high temp use

      We do not recommend using this product outside the standard temperature range.

        Development changes

        increased development reduces the maximum permissible load.

        Vertical mounting

        This slide can not be mounted vertically (guillotine).
