Technical informations


Applications

This slide guide is intended for medium duty applications, such as hoods or enclosures for guard of medium size machine, drawers of medium loads requiring improved access.

Recommended operating temperatures from -20 to 80°C.

Installing these guides in applications with severe vibrations is not recommended: indentation of profiles by ball bearings might occure. Do not hesitate to contact us.

Mounting on a minor axis: Increased risk of friction between beams during operation. A flat mounting will create significant deflection.
Increase space between the beams through spacers not supplied, in order to avoid the scraping due to the deflection.

These slides are not designed to withstand intensive use.

This product can be used as a keyboard drawer, Slide-pan, telescopic rod, drawer slide, furniture slide, handling rail, suspended horizontal guidance, or in some cases, as vertical guide as guard door.

Manufacture

Chambrelan produces this telescopic slide using cold rolled steel profiles.

Anti-corrosion standard coating is a silver zinc, of a 12 microns average thickness, which offers excellent resistance to the salt spray test.

It is equipped with polyamide stoppers when opening and rubber stoppers when closing.

It has ball cages made of polyamid.

Its ball bearings are made of 100C6 chrome steel. It is greased with a high pressure 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...

Greasings

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.

    Options

    Manual lock

      It has no lock option so far.

      Double extension

      • R28DD : the slide opens from both sides. This can be used for transfer hatches.

      Surface treatment

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

      Stainless stell ball bearings mounting

      It can be mounted with stainless steel balls to get a very good corrosion resistance, which in some cases can provide an economical alternative to stainless steel slides.

      high temp use

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

        Development changes

        The extension of this slide cannot be modified on stock items. On request, we can produce the requested extension. Please allow a production lead time.

        increased development reduces the maximum permissible load.

        Vertical mounting

        This slide can be mounted vertically. However, to avoid jamming, it is necessary to install, during production, additional stoppers to relocate the ball cages. It is therefore necessary to specify the type of installation requirements: downward or upward movement.
