Airtac LSH Linear Guide Rail LSH15HN2X1140S15AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN2X1140S15AN-M4 is a standard-type profile linear guide on a 15 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 LSH15HN2X1140S15AN-M4
LSH15HN2X1140S15AN-M4 is a complete AirTAC LSH linear guide set: two standard-length square carriages riding one 1140 mm profile rail with a 15 mm end-hole offset. The size code and the rail width agree on this model - 15 mm - so the mounting datum can be laid out straight from the code. Each carriage carries four rows of recirculating balls in X-shaped 45 degree arc raceways, loaded at a 45 degree contact angle with two-point contact per ball, which gives equal capacity in all four directions and self-alignment: small mounting-surface errors are taken up inside the carriage rather than binding the block.
Ratings are per carriage: 11.3 kN basic dynamic (C), 17.9 kN basic static (C0) and 0.12 kN.m in each of the MR, MP and My directions. Two carriages on the shared rail split the working load and resist tipping along the travel direction. Static sits about 1.6 times dynamic across this range - size on C, the number that governs travel life, not on the larger C0. And note what preload A buys you: at 500 mm rail spacing this set tolerates a 130 um height error between rails, where a medium-preload version would demand 35 um - nearly four times tighter - so an unpreloaded set is the forgiving choice on a roughly machined base.

Where the Airtac LSH Linear Guide Rail LSH15HN2X1140S15AN-M4 Is Used
Laser engraver gantry
A desktop CO2 laser engraver with about a metre of X travel suits this set: two carriages carry the head bridge across the 1140 mm rail, cutting loads are light, and the unpreloaded carriages keep belt or lead-screw drag low so a small stepper accelerates the gantry crisply.
Laboratory sample shuttle
A liquid-handling station moving microplates roughly 1.1 m between pipetting and read stations: the self-aligning carriages tolerate an aluminium extrusion frame, and the 17.9 kN static rating per carriage is ample for plate payloads of a few newtons.
Vision inspection camera rail
An overhead camera sliding past inspection stations on an electronics line: the 0.12 kN.m moment rating per carriage carries the cantilevered camera bracket, and normal accuracy is enough for image-based checks that do not need metrology grades.
Is the Airtac LSH Linear Guide Rail LSH15HN2X1140S15AN-M4 the Right Guide?
If the duty is light and the mounting envelope tight, look first at stepping down to AirTAC LRM - its load ratings are not published, so we confirm them against your duty before you commit. Where moment governs instead of load, one size up pays: LSH20 standard carriages raise MR from 0.12 to 0.27 kN.m, more than double, for a single part change. Choose LGC only when the travel is short and the job wants crossed-roller rigidity rather than long recirculating-ball travel. Match checklist: form (set, carriage or rail), size against both load and moment, carriage style and length, carriage count and rail length, accuracy and preload with the installation trade-off priced in, grease fitting, and - if replacing a single part - the pairing code from the original.
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 LSH15HN2X1140S15AN-M4 FAQ
Per standard-length carriage: basic dynamic load rating C 11.3 kN, basic static load rating C0 17.9 kN, allowable static moments MR 0.12, MP 0.12 and My 0.12 kN.m. Running parallelism for the normal (N) accuracy grade is 12-37 um depending on rail length. Mount the rail with M4 screws at 412 N.cm into steel, 274 N.cm into cast iron, 206 N.cm into aluminium. Each carriage arrives with a 0.9 cm3 Mobilux EP2 charge; top up 0.3 cm3 via the M4 fitting every 100 km of travel or every 3 to 6 months, then stroke the carriage at least three carriage-lengths twice and check for an even film.
Yes, preload is an ordering choice: A none, B light, C medium (heavy D does not exist on size 15). Rigidity is not free - at 500 mm rail spacing the allowable height error between rails falls from 130 um with no preload to 85 um at light and 35 um at medium, and parallel error from 25 to 18 to 13 um. Whatever grade you choose, the achieved accuracy depends on pulling the rail flat against its datum face and torquing the M4 screws correctly, and on corner radii not exceeding 0.5 mm.
