Automotion Components X-Rails
What is...
Features
The X rail system is a highly cost-effective product made of zinc plated steel (L1970), the stainless steel version (L1971) has a high level of corrosion resistance.
Cost-effective and corrosion resistant
The X rail is relatively inexpensive as it is based on a rolled formed, steel section. It allows for adjustments due to misalignment of the structure that it is being used on and with internal raceways is suited for robust use but is not suitable for applications having signifi cant moment loads.
The stainless steel (316L) version uses FDA and USDA compliant materials.
Stocked
Same day despatch for lengths of up to 3 metres.
Zinc-plated version
3 sizes to allow the most cost-effective solution for light and heavy duty applications.
Stainless steel version
- High grade stainless (316L).
- For wet applications.
- 2RS (splash-proof) seals.
Flexibility in set-up
X rail allows the sliders one rail to remain fixed in place but allows some lateral movement of the sliders in the other rail to adapt to any misalignment.
T and U rail allows for misalignment
Using two T rails good set-up accuracy is required
Specifications and applications

Selecting the correct rail
Firstly
The decision needs to be made if zinc plated steel or stainless steel rails and sliders are required.
- The zinc plated steel version (L1970) of the product is considerably less expensive than the 316L stainless steel type (L1971).
- The rollers in the zinc plated (L1970) sliders are protected by 2Z metal bearing covers. These are not meant to be used in anything other than a dry environment.
- The L1971 stainless steel X rail system is resistant to water and many chemicals. The slider rollers have rubber 2RS roller seals – being water resistant (not to be used fully submersed).
Secondly
The size of system to be used is selected.
- There are three diff erent rail and slider sizes: 20, 30 and 45.
- The load that is being carried and its shape needs to be considered. The X rail system is not really suited for moment loads. If moment loads exist then two or more rails/sliders should be used to off set this. Typically 2, 4 or more sliders are used and the load carried should be divided over the number of sliders bearing in mind that if using a U rail slider along with a T rail, the U rail sliders do not have any axial load capacity.
- The rails are supplied in standard lengths of 1040mm, 2080mm and 3120mm – and can easily be cut to other required lengths by Automotion (on request).
Finally
Decide whether a low profile slider or a solid body slider is required (low profile sliders are only available for T rails). The low profi le (L1970.CES and L1971.CEX) sliders are less expensive than the solid body sliders.
Please note
It is very important to ensure that the correct low profile fixing screws are used with this rail (see part no. L1970.S for zinc plated steel and L1971.S for stainless steel). Using other higher profi le heads may lead to contact between the underside of the slider and the top of the screws.
