Airtac LSH Linear Guide Rail LSH30RLX2394-S37-N-E
The AirTAC Airtac LSH Linear Guide Rail LSH30RLX2394-S37-N-E is a standard-type profile linear guide on a 28 mm wide rail. Four rows of balls contact X-shaped raceways at a 45° angle, so the guide carries load equally in all four directions and absorbs small mounting errors inside the carriage instead of binding.

About the Airtac LSH Linear Guide Rail LSH30RLX2394-S37-N-E
Ordered as LSH30RLX2394-S37-N-E, this is a single hardened profile rail of the LSH size 30 family, 2394 mm long, grade N, with pairing code E and no carriage of any kind in the box. It exists for buyers who already hold serviceable carriages or who build rails into machine frames of their own design. The four-row ball geometry that gives LSH equal capacity in all four directions lives in the carriage, not here; what this part guarantees is straightness, a hardened raceway and a 28 mm true width - size 30 in the code, 28 mm on the drawing.
Grade N parallelism runs in a 12-37 um band over this length. The S37 end-hole offset puts the last bolt centres 37 mm from each rail end - relevant where a dead plate or bellows clamp wants that space at the stroke ends. Maximum rail length for size 30 is 4030 mm, so 2394 mm leaves more than 1600 mm of extension headroom. After mounting, seat the supplied bolt caps fully into the counterbores: lay a flat plate over each cap, tap vertically with a plastic mallet, then confirm no cap stands proud of the rail top, or swarf will work into the ball circuit of whatever carriage runs on it.

What Is In The Box
| This order | Rail only |
|---|---|
| Rail | Yes, 2394 mm |

This is a bare rail cut to length. NO CARRIAGE IS INCLUDED. If you are not sure which form you need, send us the machine or the original part number and we will confirm it before you order.
Where the Airtac LSH Linear Guide Rail LSH30RLX2394-S37-N-E Is Used
Pallet conveyor transfer
A pallet transfer line runs its carriage-mounted lift stations over rails like this one; swapping a single worn 2394 mm section keeps every other block on the line in service.
Assembly machine rebuild
During an overhaul of an automated assembly cell, a scorched rail goes out and this grade N replacement goes in, while the original pairing-E carriages are cleaned, topped up with 1.7 cm3 of Mobilux EP2 and refitted.
Straightening press feed
A bar-straightening press feeds stock on a carriage riding this rail; the S37 end-hole spacing lets the feed-stop bracket sit close to the rail end without fouling the last bolt.
Is the Airtac LSH Linear Guide Rail LSH30RLX2394-S37-N-E the Right Guide?
Match this rail to LSH30 carriages bearing pairing code E; without the same letter, smoothness, preload and accuracy are not covered. For sizing: light duty and a small footprint point to LRM, whose ratings we confirm case by case because they are not published; a cantilevered load points up to a long LSH30 carriage (MR 0.88 kN.m) or to LSH35 (MR 1.05 kN.m); short travel needing crossed-roller stiffness points across to LGC. The order checklist: confirm the form is rail only; size by load and moment together; carriage style, length and count; rail length; accuracy grade; preload grade, with the tightening installation tolerances it brings; the carriage-side grease fitting; and the pairing code off the part being replaced.
Quick checklist
- ✓ Complete set, carriage only, or rail only?
- ✓ Worst-case moment, not just straight load
- ✓ Travel length and mounting space
- ✓ Accuracy grade and preload
- ✓ Mounting surface ground or finish-milled
- ✓ Pairing code, if replacing a part
Installation & Maintenance Notes
- check Mounting surface must be ground or finish-milled.
- check Torque the rail screws per the recommended figures, in sequence.
- check Keep the mounting corner radius inside the stated R maximum.
- check Do not angle the carriage onto the rail; balls can drop out.
- check Drive the supplied bolt caps into the mounting holes.
- check Re-grease every 100 km of travel or every 3–6 months.
- check Installation by qualified personnel per AirTAC docs.
Airtac LSH Linear Guide Rail LSH30RLX2394-S37-N-E FAQ
True rail width is 28 mm (the size 30 code is not the width). Length is 2394 mm, 1636 mm short of the 4030 mm maximum for this size. Grade N accuracy gives 12-37 um running parallelism depending on final length. The S37 offset fixes the outermost mounting holes 37 mm from each rail end. Fasten with M8 cap screws at 3040 N.cm in steel, 2010 N.cm in cast iron or 1470 N.cm in aluminium, against shoulders H 6.5, H1 5 and H2 5 mm with a 1 mm maximum corner radius. Dynamic, static, moment and preload figures come from the carriage you fit, not from the rail.
No carriage is included - the order is the hardened rail cut to 2394 mm plus its bolt caps. Every LSH rail and carriage carries a pairing letter, E in this case; rails and carriages must share the letter for the rated smoothness, preload and accuracy to hold. If you cannot read the code off your old part, send us the full SKU printed on the carriage or rail and we will match it.
