Description
This 3 beam anodised aluminum slide, offers a full extension.
Very comptact and with a 1U high, its sliding is smooth and silent.
It is intended for medium loads in applications requiring a very small footprint.
Applications
This slide guide is intended for medium loads requiring few cycles, such as covers or guards on machines, keyboard tray or total extension drawers for electronic devices. Very light, it is particularly well suited for aerospace applications.
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.
This slide is very compact, do not use flat mounted: increased risk of friction between beams during operation. In addition, a flat mounting will create significant deflection.
Mounting in the minor axis is not recommended as the sections could deform when under load increasing friction and possibly damaging the slide.
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 extruded aluminum profiles.
Anti-corrosion standard coating is soft anodisation.
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 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...
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
D444V lock opened: when extended, push the lock to close the slider.
D444F lock closed: when closed, push the lock to open the slider.
D444VF lock opened and closed: when extended, push the lock to close the slider, when closed, push the lock to open the slider.
In most cases, only one locking slide is required for the locking of the drawer to be achieved.
When mounting in vehicles, we invite you to contact us if you plan to use locking slides.
the presence of lock and latches makes some shorter lengths impossible to manufacture. Moreover some standard holes may not be present.
we do not recommend locking options for use in vertically mounted (guillotine) applications.
Disconnect
D446 the inner beam can be removed and reintroduced into its slideway. This option can be useful in cases of difficult assembly conditions or applications requiring external maintenance.
Surface treatment
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.
hard anodizing is not recommended with locks in opened position.
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 (guillotine).
