Airtac LSH Linear Guide Rail LSH15HN1X280S20AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN1X280S20AN-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 LSH15HN1X280S20AN-M4
AirTAC LSH15HN1X280S20AN-M4 arrives as a working pair: one 280 mm hardened-raceway profile rail plus one square standard-length size 15 carriage, so no second order is needed to make an axis. Rail width is 15 mm, in step with the code. The carriage runs on four rows of recirculating balls whose X-set 45 degree arc raceways give two-point contact per ball, so push, pull, lift and side loads all share the same rating while minor seat misalignment is ironed out inside the block.
Normal accuracy and no preload keep this build forgiving: at 500 mm rail spacing you may allow 25 um of parallelism error and 130 um of height error, scaling with actual spacing. The per-carriage figures are C 11.3 kN, C0 17.9 kN and 0.12 kN.m moments. What decides the straightness you actually get is fitting craft - machine the shoulders to H 3.5, H1 3 and H2 4 mm with a corner radius no greater than 0.5 mm, torque the M4 screws to 412 N.cm into steel, and seat the supplied bolt caps flush so swarf stays out of the ball circuit.

Model Code: Airtac LSH Linear Guide Rail LSH15HN1X280S20AN-M4
| LSH | LSH Series Linear Guide. |
|---|---|
| 15 | Size code. |

Where the Airtac LSH Linear Guide Rail LSH15HN1X280S20AN-M4 Is Used
Packaging diverter pusher
A pusher that nudges snack packs off a conveyor at a fixed station: the 280 mm rail gives the stroke, 0.12 kN.m moment per carriage covers the overhung pusher arm, and equal four-direction capacity absorbs the side thrust of the push itself.
PCB inspection camera rail
An AOI camera gliding above a printed-circuit-board conveyor along a 280 mm span: normal accuracy is sufficient at vision magnification, and self-alignment copes with a folded-sheet steel camera bridge.
Fixture shuttle on a drilling table
A drilling table where an operator slides a clamped workpiece between drill and tap stations on a 280 mm guide: four-row ball circulation keeps the shuttle rolling under clamp-side loads, and bolt caps seated flush in the rail keep chips out.
Is the Airtac LSH Linear Guide Rail LSH15HN1X280S20AN-M4 the Right Guide?
Decide the form before anything else: this SKU is a complete rail-and-carriage set, while replacement parts are ordered as carriage-only (BK) or rail-only (RLX) codes matched by pairing letter. Then size by moment, not just load - 0.12 kN.m per carriage on this set - and remember that a second carriage on the same rail is the fix for tipping along the direction of travel, whereas one size up to LSH20 is the fix for moment across it. For light duties in tight envelopes, LRM steps down, with ratings we confirm on request; LGC steps across for short travel needing crossed-roller rigidity.
Check before you order: the form, size versus load and moment, carriage style and length, carriage count and rail length, accuracy and preload against the mounting tolerance you can actually hold, an M4-family grease fitting, and the pairing code for any replacement 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 LSH15HN1X280S20AN-M4 FAQ
Each standard-length LSH15 carriage: C 11.3 kN, C0 17.9 kN, moments MR/MP/My of 0.12/0.12/0.12 kN.m; N grade running parallelism 12-37 um. Rail fixing: M4 screws at 412 / 274 / 206 N.cm on steel, cast iron and aluminium bases. Shoulders H 3.5, H1 3, H2 4 mm, corner radius 0.5 mm maximum. Grease: 0.9 cm3 initial, 0.3 cm3 top-up per carriage, every 100 km of travel or every 3-6 months, whichever comes first.
Both add stiffness, but they cost different things. Preload tightens what your mounting surface must achieve: at 500 mm spacing, height error S is limited to 130 um with no preload (this code), 85 um at B and 35 um at C, and parallelism error to 25, 18 and 13 um. A second carriage on the same 280 mm rail leaves those tolerances untouched while halving the load and moment carried per block and resisting tipping along the travel. Choose preload for rigidity against vibration; choose count for load sharing and tipping.
