Airtac LSH Linear Guide Rail LSH15HN2X510S15AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN2X510S15AN-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 LSH15HN2X510S15AN-M4
LSH15HN2X510S15AN-M4 is a complete AirTAC LSH linear guide bought in one line: a 510 mm profile rail carrying two standard-length square carriages, with M4 grease fittings in the blocks and a 15 mm end-hole offset for the fixing screws. Each carriage runs four rows of recirculating balls in X-shaped 45 degree arc raceways with two-point contact per ball, so the block carries equal load up, down and sideways and absorbs slight mounting-surface error internally instead of binding. Size 15 is honest here: the rail really is 15 mm wide.
Per carriage the catalogue gives 11.3 kN dynamic, 17.9 kN static and 0.12 kN.m moment in the pitch, roll and yaw directions; two blocks on one rail double those per-axis figures and largely design out tipping along the travel. Because preload is A, the set accepts the loosest installation window in the table - at 500 mm rail spacing you may leave up to 130 um height and 25 um parallel error between rails - so a well-milled base plate is usually good enough.

Where the Airtac LSH Linear Guide Rail LSH15HN2X510S15AN-M4 Is Used
Pick-and-place head on an SMT bench line
A twin-block LSH15 axis carries the Z-head of a small pick-and-place unit across a 510 mm span; the second square block stops the head racking as it lifts PCB assemblies off the feeder.
Diverting gate over a packaging conveyor
A short-stroke pusher gate riding above a carton conveyor uses the 510 mm guide as its slide, with two blocks carrying the side thrust so the gate lip does not tip under load.
Benchtop XY adhesive dispensing table
A lab-scale dispensing table built from two of these 510 mm axes gives repeatable straight-line syringe travel; preload A keeps running drag low for the light payload.
Is the Airtac LSH Linear Guide Rail LSH15HN2X510S15AN-M4 the Right Guide?
Step down to AirTAC LRM when the duty is light and the envelope tight, but note that LRM load ratings are not published, so we confirm them before you commit. Step up one size when the load cantilevers - LSH20 N lifts the moment rating from 0.12 to 0.27 kN.m, a bigger jump than C alone gives - or take a long LSH15L carriage if you must stay in this footprint. Step across to LGC where travel is short and crossed-roller rigidity matters more than long recirculating run.
Checklist before ordering: form (this is a complete set), size chosen against load AND moment, carriage style and length (here square, standard), block count and rail length, accuracy grade and preload with the installation trade-off, grease fitting (M4 family only on size 15), and the pairing code if you are replacing a single part.
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 LSH15HN2X510S15AN-M4 FAQ
Per carriage: 11.3 kN basic dynamic (C), 17.9 kN basic static (C0), and 0.12 kN.m allowable moment in each of the MR, MP and My directions. Normal-grade running parallelism falls between 12 and 37 um depending on the rail length band. Fix the rail with M4 screws torqued to 412 N.cm in steel, 274 N.cm in cast iron or 206 N.cm in aluminium. Each block leaves the factory with 0.9 cm3 of Mobilux EP2 and takes 0.3 cm3 at top-up; renew the grease every 100 km of travel or every 3 to 6 months.
One box, one assembly: a 510 mm LSH15 rail with two standard square carriages matched to it, M4 fittings already in the blocks, and bolt caps for the screw holes. Nothing else is needed to make the guide work - fixings into your machine are your own. Preload A is a genuine advantage on a modest base: at 500 mm spacing you may tolerate 25 um parallel and 130 um height error between rails, roughly four times looser than the medium-preload set demands, so self-alignment has real error to work with rather than a surface that must be ground.
