Airtac LSH Linear Guide Rail LSH15HN2X470S25AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN2X470S25AN-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 LSH15HN2X470S25AN-M4
LSH15HN2X470S25AN-M4 is a complete guide set: one 470 mm hardened rail whose first mounting hole sits 25 mm from each end, with two square, standard-length carriages running on it from the factory. Each carriage holds four rows of recirculating balls in crossed 45 degree arc grooves with two-point contact per ball, which is why the slide carries the same rating vertically, laterally and under compression, and self-aligns over minor machining imperfection. The 15 in the code is the true rail width at this size.
Moment is where size 15 is modest: MR, MP and My are 0.12 kN.m per carriage, against C 11.3 kN and C0 17.9 kN. When the load overhangs - a sensor arm, a dosing nozzle - two blocks spaced as far apart as the application allows on the 470 mm rail resist tipping better than one larger block. And one step up to LSH20 lifts MR to 0.27 kN.m, roughly 125 percent more moment capacity in a single part change. Grade N accuracy runs a 12-37 um parallelism band, preload A keeps the installation window at its widest, and 470 mm leaves ample headroom below the 4040 mm maximum rail length for this size.

Where the Airtac LSH Linear Guide Rail LSH15HN2X470S25AN-M4 Is Used
Drilling-jip sliding fence
A sliding fence on a small drilling and tapping jig takes repeated clamping side loads; the twin-block layout on 470 mm of rail keeps the fence square to the spindle axis trip after trip.
ICT fixture press slide
An in-circuit test fixture pressing a topplate of probes onto a PCB benefits from two carriages sharing the pressing load, keeping the board flat without a second machined rail.
Parcel dimensioning scanner arm
A logistics dimensioner sweeping a measuring head over parcels rides on this twin-block set; the 25 mm end-hole offset suits frames already drilled on a 25 mm pitch from the end.
Is the Airtac LSH Linear Guide Rail LSH15HN2X470S25AN-M4 the Right Guide?
Match before you order: set form, size checked by load and moment together, square standard carriage, count 2, 470 mm rail with 25 mm end offset, grade N accuracy, preload A, M4 lubrication fitting. If the load is light and the envelope small, LRM is the step down - its load ratings are not published, so we verify them against your duty first. If the load overhangs, remember the arithmetic: LSH20 buys 0.27 kN.m of MR against 0.12 here, a 125 percent gain in one part. Short strokes wanting crossed-roller rigidity rather than recirculating travel point to LGC instead.
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 LSH15HN2X470S25AN-M4 FAQ
Each standard-length square carriage: C 11.3 kN dynamic, C0 17.9 kN static, MR 0.12, MP 0.12 and My 0.12 kN.m allowable moment. Accuracy grade N means running parallelism between 12 and 37 um depending on the finished rail length. Fixing is M4 screws at 412 N.cm into steel, 274 N.cm into cast iron, 206 N.cm into aluminium. Lubrication is 0.9 cm3 of Mobilux EP2 first charge per carriage, 0.3 cm3 top-ups, repeated every 100 km of travel or every 3 to 6 months.
One 470 mm rail, two square carriages already on it, the rail bolt caps and the M4 grease fitting; you add your own M4 mounting screws torqued to the figures above. A worn carriage can be renewed on its own at roughly a quarter of the price of a whole set - the ball circuit is what wears, and the hardened raceway rail is reusable provided its surface is undamaged. To order the correct spare, quote the model and pairing code from the original carriage so the replacement matches the rail's grade and preload.
