Steel linear rail with ball bearing runner
Description
This steel linear rail has its length according to customer needs.
It includes one or many hardened steel runners, that also contains plastic items in their construction.
Each runner has a load capacity. Increasing the number of runners increases the load capacity by the same factor.
A guide rail is made of a ball bearing roller which runs in a linear rail. It is commonly referred to as linear ball bearing, linear ball slide, linear bearing and rail, linear bearing rail, linear bearing slide, linear movement, linear rail, linear rail bearing, linear rail system, linear slide rail, linear slide system, linear sliding, rail linear, rail slide, rail sliding, slide rail, slide track, sliding rail, sliding track

Technical informations
Applications
This linear rail is designed for heavy loads in applications requiring a very small footprint, such as covers or enclosures for guard of small machine ..
Recommended operating temperatures from -20 to 100°C.
CAUTION: This kind of product will not slide well under torque; please ensure that the load is balanced on one or more runners, if necessary.
This product can be used as a sliding pair, guide bar or rod, suspended rail, handling rail, sliding doors horizontal slider or vertical guide.
Manufacture
Chambrelans production of this guid rail is based on the use of cold drawn stainless steel profiles.
Anti-corrosion standard coating for the rail is a silver zinc, of a 12 microns average thickness, which offers excellent resistance to the salt spray test. Runner is nitrurated.
The rail has axial pins covered with rubber at each end.
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)
Options
Manual lock
It has no lock option so far.
Coating
This slide can be delivered in yellow or black zinc coating. Other treatments ensuring better corrosion resistance are also available. Do not hesitate to contact us.
A nitruration coating of the rail 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
CAUTION: 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.
CAUTION: the zinc coating deteriorates above 120°C, we can offer other solutions.
Vertical mounting
This slide can be mounted vertically (guillotine).
