1. 1003-Load capacity
The load is the maximum effort which an extended pair of slides, mounted on the major axis can bear. Load capacity varies from a few kilos to more than 1500 kg. The maximum safe load is given:
- Mounted on the major axis,
- with a load spread uniformly along the small inner beam.
Deflection is the non permanent deformation when a fully extended slide is loaded. This deflection is depending on to the extension, the load, the type of mounting (major or minor axis) and the mounting conditions. It is directly proportional to the load. The figures are given on the product pages and on the technical data sheets.
3 Types of materials:
- Stainless Steel.
STEELChambrelan makes its slide profiles by cold drawing out or machining in long lengths, generally 6 meters. This manufacturing method improves the quality of the steel used due to workhardening. Learn more So, a cold drawn XC10 used in ranges like the RA5R offers the quality of semi hard steel on its ball tracks. On heavy duty products, Chambrelan uses semi-hard type XC35 steels, also workhardend. Learn more The balls are made of chromium (100C6) steel.
ALUMINIUMOur profiles are mainly extruded 6060T5. The balls are made of chromium (100C6) steel. Learn more
STAINLESS STEELOur profiles are in 304L, cold drawn or machined. The balls are made of stainless steel. Learn more
4. 1006-Surface treatment
All slides are treated against corrosion. Our standard treatment is zinc plating (RoHS compliant) for steel slides and colourless anodization for aluminium models suits most applications. All slides come with a treatment against corrosion. The standard treatment, RoHS compliant, suits most uses.
5. 1007-Reinforced slides
consist of enclosing reinforced ball bearings within the body of the slides. This process restricts twisting of the beams under load and enables the load capacity to be greatly increased at the same time as it reduces the pull-out & push-in forces. We mainly focus on heavy duty slides. Among our products, we have developed a range of slides called "reinforced", which has now replaced the standard slides. This feature consists in the inclusion of additional reinforcing ball bearings within the body of the slides.This process reduces out the twisting of the beams when under load. This modification enables the load capacity to be greatly increased at the same time as it reduces the pull-out and push-in forces. This type of product is highly recommended for applications where the slide undergoes a torque or for mountings on the minor axis.
Optional locking devices enable the slide to be held in various positions: extended (V), closed (F) or both (VF). By manually activating the latch, the draw and slides are able to operate normally. If considering the use of locks for vehicle applications, please contact us for further advice. Three locking types are possible, i.e. :
Lock in the opened position
Lock in the closed position
Lock in the open and closed positionsThe unlocking of the intermediate beam on 3 or beams slides is automatic. NB: In most uses, out of two slides, if only one is fitted with a lock, it is enough to block the drawer or the mobile part in the required position. The handle can be a useful device and provides easier access to lock systems.
7. 1010-Double extension
An extension towards the front or the back of the fixed parts can be adapted on some slide types. Though easy to set up on 2 beams slides, it needs a synchronising system on the 3 beams slides. Double extension is an extension towards the front or the back of the fixed part NB:
- This makes the setting up of an internal locking system impossible.
- Flat mounting may be impossible on some slides; please refer to the product page for more information.
8. 1011-Table Slides
The outer beam includes 2 devices that extend on each side. This is suitable for example for tables with central opening.
9. 1012-Disconnect Option
Disconnection is an option on some types which allows you to remove the mobile part from the slide and then to insert it again in the same slide. This option is necessary when installation is carried out in cramped premises where it would be hard to mount standard slides or for materials requiring maintenance. This system is very technical and, therefore, very sensitive to mishandling. That is why Chambrelan prefers that fast hitching systems, such as studs, are used as often as possible.
Standard operating temperatures are between -20°C and +80°C. Some slides can be used within temperatures from - 50°C to +250°C. Specific greasing can be applied. Please warn us before production. Learn more...
11. 1014-Speed of use
Telescopic SlidesThe maximum speed of use for telescopic slides is 0.3m/s.
Linear railsThe maximum speed of use for linear rails is 0,5m/s.
12. 1017-Mounting rules
Our slides are designed to bemounted on the major axis, per pair, with a uniformly distributed load on the smaller moving beam. Some rules on good mounting: Used by pair,Mounted on the major axis,Evenly distributed load,Mounting surfaces are flat and even,Use all fixings provided,Slides are parallel on every axis,Align slides fronts,Use complete travel,Distance between slides less than 2 metres,Room temperature,Fully extend slides before assembly.
13. 1018-Mounting on a minor axis / Mounting with torque
Only some slides can be used for these types of stress. Learn more... A mounting on the minor axis reduces the load capacity of the slides. Moreover, deflection and moving forces will increase. Please refer to the product pages for more information. Some slides need an increased space between the beams (ref C on the sketch) through spacers not supplied, in order to avoid the scraping due to the deflection.
14. 1020-Intensive use
In more demanding applications where shock and vibrations and excessive dirt are expected, we suggest nitruration of the beams. Learn more...
15. 1021-Polluted environment
In harsher environments, where a build up of excessive dirt particles can lead to seizure, we recommend users regularly clean and maintain the slides.You might also have to consider additional means of protection at the design stage.
To maximize worklife duration, slides are lubricated with a high pressure grease, which reduces the need for maintenance. In more extreme working environments, slides need to be regularly and systematically cleaned. Rails have to be regularly lubricated. Learn more...
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 : ExtensionsPart lengthsDrillings, diameters and hole centresSurface treatmentsOptions and fittings for fixingLubrication Do not hesitate to contact us.
The various parts of the slides have manufacturing tolerances. The tolerances are offset by fitting different ball bearing diameters to ensure an easier movement. The standard fitting is suitable for most applications. According to your needs, the slides can then be assembled very tightly, or, conversely, very loosely,if the application requires it, as is the case for mountings in hot enclosed spaces.
19. 1043-Synchronization of full extension or super extension slides
1- Purpose of this sequential device 2- Concept 3- Advantages of this mechanism 4- Limitations and contradictions 5- More information?
1- Purpose of this sequential device:In a normal telescopic slide, the opening of the beams can be done in a nonsequential way. The moving beam extends first. The other elements of the slide are then subjected to a torque which increases the force required to move them out. On some slide references, a sequential opening of the beams is possible.
2- Concept:Synchronization (or sequential opening) solves this phenomenon: 1- the moving beam is kept closed until the intermediate is completely opened. It is therefore subjected to a reduced torque, whilst extended. 2- then the moving element can expand: This system, which is possible on some heavy duty 3 or 4 beams slides, considerably reduces the opening forces by controlling the opening order of the telescopic slide beams. It is achieved :
- either by magnetic end stop,
- or by mechanical levers.
3- Advantages of sequential opening:
- The opening force is reduced;
- The lifetime is increased;
- Ball cages migration due to insufficient parallelism is reduced.
4- Limitations and contradictions:This system is not recommended in case of vertical use (guillotine). It also does not work in the case of high temperature installation (in an furnace).
5- More information?For additional information, do not hesitate to contact us... Few examples of sequential telescopic slides: RA7R E1020
Standard slides are delivered lightly greased. We use a high pressure bearing grease for steel slides and a white grease for aluminum and stainless slides. Learn more Upon request, we can use: food grease (compatible clean room)a high temperature greasea teflon free grease (for spray booths...)grease free mounting (although we do not advise this option) The slides are delivered lightly greased. We recommend greasing abundantly raceways after installation, especially in case of intensive use. NB: Regular lubrication extends the life of slides.
The slides do not have a device to protect against particles. As with any ball bearings devices, telescopic slides and linear guides are very sensitive to projections of particles in the raceways. The balls bearing will be stopped by the obstable and sliding will be stopped. We don't provide standard protection device against projections.Each case must be studied specifically. This should be considered at the design stage. On some rails, we can provide an optional wiper. E53 ST53 SNT
