Applications

This guide is designed for simple medium duty applications, such as medium duty covers or housings for machine protection, or medium duty sliding drawers. Recommended operating temperatures are -20 to 80°C. Avoid installing these guides in applications subject to severe vibration, as this may result in rapid matting of the profiles by the balls. Please consult us. Flat mounting: Risk of friction of the profiles. In addition, flat mounting leads to significant deflection. Increase the spacing between the elements by using shims not supplied in order to avoid friction due to the ...

Flat mounting: Risk of friction of the profiles. In addition, flat mounting leads to significant deflection.
Increase the spacing between the elements by using shims not supplied in order to avoid friction due to the deflection.
These slides are not designed to withstand heavy duty applications.
This product can be used as a keyboard drawer, housing slide, telescopic bar or telescopic rod, drawer slide, furniture slide, translational guide, handling rail, suspended rail, horizontal guide or in some cases as a vertical guide such as a housing guide.

Manufacturing

Chambrelan manufactures this slide on the basis of galvanised steel profiles. It is supplied as standard with a white zinc coating, with an average thickness of 12 microns, which offers excellent resistance to salt spray tests. It is equipped with polyamide stops for opening and closing. It has zinc-plated steel ball cages. The balls are made of 100C6 chrome steel. It is lubricated with standard bearing grease. The thin profile requires the support to be milled. Chambrelan specialises in the design and manufacture of telescopic ball bearing slides and guide rails for industrial applications: ...

Chambrelan specialises in the design and manufacture of telescopic ball bearing slides and guide rails for industrial applications: reinforced slides, linear slides, ball bearing guides, metal runners in steel, aluminium, stainless steel with locking, blocking and in full extension, partial extension, double stroke or super extension for heavy duty industrial drawers, mechanical panels.

Maintenance

As standard, our slides are delivered lightly greased from the factory. We use a high pressure bearing grease for steel slides, and a white grease for aluminium and stainless steel slides. On request, we can use a food grade grease (clean room compatible), a high temperature grease, a teflon free grease (paint booths) or a greaseless assembly (although we do not recommend this).
A food grade grease, combined with stainless steel balls, offers an economical alternative to all stainless steel slides.

Options

Manual locking system It does not have an internal locking option at this time. Double development (DD) The slide can be opened from both sides. This makes it possible to create transfer locks, for example. Surface treatments Other surface treatments are also possible to increase the strength of the slide. Please consult us. Mounting with stainless steel balls It can be mounted with stainless steel balls to achieve very good corrosion resistance, which in some cases can offer an economical alternative to stainless steel slides.
