Airtac LSH Linear Guide Rail LSH15HN1X216S18AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN1X216S18AN-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 LSH15HN1X216S18AN-M4
LSH15HN1X216S18AN-M4 is a complete linear guide set in the AirTAC LSH series: one hardened profile rail cut to 216 mm and one square (H) carriage of standard length, supplied matched and ready to bolt down. The size 15 rail measures a true 15 mm across - here the size code and the rail width agree. Inside the carriage, four rows of recirculating balls sit in X-shaped 45 degree arc raceways with two contact points per ball, so push, lift and side loads all meet the same capacity, and slight mounting-surface error is taken up inside the block instead of binding the slide.
Per carriage the catalogue rates this set at 11.3 kN dynamic (C) and 17.9 kN static (C0), with MR, MP and My moment limits of 0.12 kN.m each. Static sits about 1.6 times dynamic across the LSH range, which is why travel-life sizing works from C, not from the larger C0 figure. At 216 mm the rail is far inside the 4040 mm maximum for size 15, and its mounting holes start 18 mm from each end - check your plate layout against that offset before drilling.

Where the Airtac LSH Linear Guide Rail LSH15HN1X216S18AN-M4 Is Used
Compact pick-and-place module
A benchtop pick-and-place unit shifting small connectors between feeder trays: the 11.3 kN dynamic rating and slim 15 mm rail keep the envelope tight while the square carriage carries combined lift and side loads.
Laboratory dosing stage
An analytical-instrument dosing axis that indexes sample vials under a probe: normal accuracy and the self-aligning four-row geometry keep travel straight on a lightly machined base plate.
Small vision inspection slide
A camera slide carrying a compact vision sensor across PCB inspection travel, where the 216 mm rail leaves mounting margin at both ends of the stroke.
Is the Airtac LSH Linear Guide Rail LSH15HN1X216S18AN-M4 the Right Guide?
Because size 15 is the lightest LSH, check downward first: an LRM roller guide suits lighter, tighter duties, but its load ratings are not published, so send us the duty and we confirm them. If the travel is short and stiffness matters more than reach, an LGC crossed-roller unit is the cross-over choice. Move up to LSH20 or to a long LSH15 carriage if moment governs - one size up lifts MR from 0.12 to 0.27 kN.m, more than doubling it. Checklist: form - complete set; size 15 checked against load AND moment; square standard carriage, one per rail; 216 mm rail with 18 mm end offset; accuracy N, preload A; grease fitting M4. No pairing code is needed - the carriage and rail arrive together.
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 LSH15HN1X216S18AN-M4 FAQ
Per carriage: dynamic C 11.3 kN, static C0 17.9 kN, moment ratings MR 0.12, MP 0.12 and My 0.12 kN.m. Running parallelism for normal (N) accuracy spans 12-37 um depending on rail length. Fix the rail with M4 screws at 412 N.cm (steel), 274 N.cm (cast iron) or 206 N.cm (aluminium). Grease first charge is 0.9 cm3 per carriage with 0.3 cm3 top-ups, re-applied every 100 km of travel or every 3 to 6 months.
You receive the 216 mm rail, the square carriage fitted to it, rail bolt caps and the M4 grease nipple - carriage and rail are matched, nothing else to pair. Preload is A (none), the most forgiving grade: at 500 mm rail spacing you may allow about 130 um of height error and 25 um of parallelism between rails. Ordering preload C would cut that height allowance to 35 um, so only pay for preload if the machine plate is machined to match.
