Description
This reinforced 2 beas zinc plated steel telescopic slide, offers a partial extension.
Strong, it encloses reinforced ball bearings that restricts twisting of the beams.
It is intended for very heavy loads in applications requiring a very strong slide.
Applications
The guide rail is very strong, both in terms of its cold drawn hardened profiles and its stops that are equipped with spring-dampers when closing and opening. It is intended for drawers carrying very heavy loads. It can be used for transfer hatch. Being equipped with reinforcing ball bearings, it may also be flat mounted. Remember that a flat mounting induce significant deflection.
Recommended operating temperatures from -20 to 80°C. After modifications during manufacturing, we can go from -50 to 250°C.
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.
This product can be used as a telescopic leg, battery drawer slide, cabinet slide, guide rail for telescopic gangway, furniture or tooling slideway bars, telescopic table, overhead rail, heavy load slide-drawer, horizontal guide.
Manufacture
Chambrelan produces this telescopic slide using hot laminated steel profiles with a cold drawn finish.
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 spring shock stops.
It has ball cages made of zinc plated steel.
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
R82F lock closed: when closed, push the lock to open the slider.
Double extension
R82DD 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.
A nitruration coating can be supplied, which offers, in addition to corrosion resistance, an increased resistance to hammering of ball bearings and a longer lifespan. This option can be usefull in the case of intensive use or applications subject to vibrations.
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
- Use in high temperature (furnace): This model can be used in high temperatures environments: up to 250°C. However, adjustments are necessary: - Additionnal play in the assembly to allow the expansion elements without blocking the slide - Use of high temperature grease - Removing of all plastic parts. These adjustments on the slides should be performed in the factory, it is important to warn us with price request or order and to allow a delay for manufacturig.
the zinc coating deteriorates above 120°C, we can offer other solutions.
Development changes
the extension of this model can be decreased or increased up to 10%.
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.
Same models
This model has equivalent models, whose overall dimensions and the diagrams of drillings are close or identical
