Airtac LSH Linear Guide Rail LSH30HN1X1240S20AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30HN1X1240S20AN-M6 is a standard-type profile linear guide on a 28 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 LSH30HN1X1240S20AN-M6
Order LSH30HN1X1240S20AN-M6 and you receive a working axis in one line item: a 28 mm wide profile rail cut to 1240 mm, with mounting holes offset 20 mm from the rail ends, carrying a single square standard-length LSH30 carriage pre-filled with grease and fitted with an M6 nipple. Nothing beyond the fixing screws and a flat datum is needed to create a running linear axis. The four-row, 45 degree X-raceway geometry gives the carriage the same capacity from every direction and lets it run smoothly over slight flatness errors that would bind a rigid guide.
Accuracy is normal (N) grade, whose running parallelism band is 12 to 37 um over the rail length, and the rail carries no preload. A 1240 mm rail sits well inside the 4030 mm maximum for size 30, so the same code extends later if the machine grows. At 500 mm spacing the size allows 40 um of parallelism error and 170 um of height error between rails; that latitude belongs to the no-preload condition and scales proportionally with your actual spacing. How firmly the rail is pulled onto its datum and torqued influences the accuracy you finally achieve more than any other single factor.

Model Code: Airtac LSH Linear Guide Rail LSH30HN1X1240S20AN-M6
| LSH | LSH Series Linear Guide. |
|---|---|
| 30 | Size code — note the rail is 28 mm wide, not 30 mm. |
| H / F1 / F2 / F3 | Carriage style: square, or flange mounted from the top, bottom, or both. |
| N | Standard carriage. |
| 1X1240 | 1 carriage on a 1240 mm rail. |
| S… | End-hole offset from the rail end, in mm. |
| A | A — no preload — higher preload raises rigidity and tightens how flat the mounting surface must be. |
| N | N — normal grade. |
| -M4 / -M6 / -A01… | Grease nipple or tube-fitting type. Restricted by size: size 15 the M4 family, 20–35 the M6 family, 45 the PT1/8 family. |

Where the Airtac LSH Linear Guide Rail LSH30HN1X1240S20AN-M6 Is Used
Laser marking gantry
The X axis of a laser marking station sweeping about 1100 mm over panels, with the marking head bolted straight onto the carriage top face.
Case diverter slide
A pusher arm on a packaging conveyor that diverts cartons between lanes over roughly a metre of stroke, cycling many times a minute.
Pallet labelling traverse
A print-and-apply labeller traverse that carries the applicator along the face of a passing pallet, needing travel of about a metre with steady guidance.
Is the Airtac LSH Linear Guide Rail LSH30HN1X1240S20AN-M6 the Right Guide?
Check the duty before the part: 37.4 kN dynamic and 55.0 kN static per carriage is generous headroom for light automation, so a smaller LRM guide may serve a tight envelope better - we will confirm its unpublished ratings with you first. Where travel is short but deflection must stay near zero, LGC crossed-roller guides are the cross-over option. Where the load overhangs the carriage face, remember the long-body option: an LSH30L carriage lifts MR from 0.66 to 0.88 kN.m, roughly a third more moment from the same rail. Match checklist: this is a complete set (no separate rail to order), H square standard carriage, single block, 1240 mm rail, N accuracy, preload A, M6 nipple; anyone ordering a spare part against a sibling axis must quote the matching pairing letter from the carriage-only or rail-only code.
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 LSH30HN1X1240S20AN-M6 FAQ
Catalogue ratings per carriage: C 37.4 kN dynamic, C0 55.0 kN static, moments MR 0.66 / MP 0.67 / My 0.67 kN.m. N-grade running parallelism falls between 12 and 37 um across the rail length bands. Mounting screws are M8, torqued to 3040 N.cm on steel, 2010 N.cm on cast iron, 1470 N.cm on aluminium. The standard carriage leaves the factory with 5.4 cm3 of Mobilux EP2 and takes a 1.7 cm3 top-up every 100 km of travel or every 3 to 6 months.
It is a complete guide in one order line: a 1240 mm profile rail plus one LSH30 square standard carriage, mounted, greased and fitted with an M6 nipple. The rail's counterbored M8 holes arrive with plastic bolt caps - seat each cap, lay a flat plate over it and tap vertically with a plastic mallet so it sits flush, then wipe the rail clean, because an open bolt hole is a direct path for swarf into the ball circuit. Fixing screws, end stops and bellows are not part of the supply.
