E72-G70, galvanized steel Linear Guide Rail

Presentation of the E72 galvanized steel industrial linear guide rail with G70 CHAMBRELAN recirculating ball bearing runner

This E72 galvanized steel linear guide rail with its G70 recirculating ball bearing runner consists of a galvanized steel rail and one or more recirculating ball bearing runners. The number of runners is limited only by the length of the rail it is generally, 1 to 3 per rail. Typical applications requiring a compact guide are sliding doors, medium sized protective covers or housings up and down type guides.

The rail is a galvanized drawn steel profile. It is equipped with a pin at each end covered with a polyurethane stop. Standard lengths range from 300 mm to 2 metres in 50 or 100 mm increments. We keep in stock rails in lengths of 500, 1000, 1500, 2000 mm. The other lengths are manufactured. The rails are delivered undrilled. We can manufacture them according to your drilling plans.

The G70 carrier, 120 mm long, is nitrided and equipped with 100C6 steel balls. It is equipped with 2 threaded inserts. The permissible load is determined according to the number of runners. Each carrier can support:

  • 300 kg on the major axis,
  • 150 kg on the minor axis.

It is suitable for applications requiring heavy load guidance.
The operating temperature range is from -20°C to +80°C continuously.

This type of product can withstand torque loads; however, be sure to balance the load as well as possible under one or more runners. Refer to the technical data sheet for more information!

E72 galvanized steel heavy-duty guide rail options:

  • Nitrided rail, which offers, in addition to corrosion resistance, increased resistance to ball matting. This option can be justified in case of application subject to vibration,
  • Rail of specific lengths and or holes according to plan,
  • Mounting with stainless steel balls to obtain very good corrosion resistance, which in some cases can offer an economical alternative to stainless steel versions,
  • Version with short carrier: E72-G70 ,
  • For use outside the recommended temperatures: G70HT pad; Contact us!

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.

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.

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.

Surface treatment

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
  • 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.

Vertical mounting

This slide can be mounted vertically (guillotine).
