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 deflection. ...

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 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 cold drawn 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 free stops on 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. 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, ...

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 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.

Locking open and closed: when folded, the lock must be operated to unfold and when extended, the lock must be pressed to fold. In most cases, only a latch slide is used to lock the entire drawer. This makes assembly and operation easier. If you are installing in vehicles, please consult us if you plan to use locking slides.

The presence of locks makes certain short lengths impossible to manufacture. In addition, some standard drillings may not be possible. We do not recommend the use of locks for vertical installation (sash type). 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. High temperature use (oven type) We do not recommend using this product outside the recommended temperature range. Modification of the standard Development: This model can be increased by 10% or decreased. An increase in development reduces the maximum permissible load. Custom lengths and strokes. Customised drilling pattern Other surface treatments (corrosion, hardness) Vertical mounting (guillotine type)
