Airtac LSH Linear Guide Rail LSH30HN1X1880S20AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30HN1X1880S20AN-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 LSH30HN1X1880S20AN-M6
LSH30HN1X1880S20AN-M6 is a long-travel LSH30 axis: one 1880 mm hardened profile rail with a 28 mm section and mounting holes offset 20 mm from the ends, carrying a single square standard-length carriage, no preload, normal accuracy and an M6 fitting. The four ball rows cross at 45 degrees so the single carriage holds an overhung load equally from any side. One carriage on a rail this long is a deliberate layout choice: it suits a moving-table machine where the table itself carries two rails, rather than a gantry beam where the rail carries the load.
The rail uses just under half of the 4030 mm maximum length for size 30, leaving room to re-order a longer section if the machine is later extended. N-grade running parallelism spans 12 to 37 um over the length. The 100 km re-grease interval is real at this travel: a 400 mm stroke cycling once every ten seconds covers 100 km in about a month, so tie the 1.7 cm3 top-up to a travel counter rather than the calendar, and keep the 5.4 cm3 first charge per standard carriage in mind when servicing.

Model Code: Airtac LSH Linear Guide Rail LSH30HN1X1880S20AN-M6
| LSH | LSH Series Linear Guide. |
|---|---|

| H / F1 / F2 / F3 | Carriage style: square, or flange mounted from the top, bottom, or both. |
| N | Standard carriage. |
| 1X1880 | 1 carriage on a 1880 mm rail. |

Where the Airtac LSH Linear Guide Rail LSH30HN1X1880S20AN-M6 Is Used
CNC router Y axis
The long Y axis of a mid-size CNC router cutting aluminium and plastics, where the moving gantry rides on profile rails of this class.
Panel cutting traverse
A cutting table that traverses a knife or plasma head across sheet material over close to two metres of travel, holding a straight line throughout.
Actuator endurance rig
An engineering test rig cycling linear actuator samples over a long stroke to log wear and force drift across thousands of hours.
Is the Airtac LSH Linear Guide Rail LSH30HN1X1880S20AN-M6 the Right Guide?
Over 1880 mm of travel, how the axis carries load decides the configuration: a moving-table layout with the load on the carriage suits one block per rail, while a gantry beam with the load on the rail usually wants the two-carriage code to resist tipping along the travel. For small light-duty axes, check LRM first - its ratings are unpublished, so we confirm them case by case. For short strokes needing maximum cross-axis rigidity, LGC crossed-roller guides are the alternative. For extra stiffness on long travel, order preload rather than the next size up: light B or medium C preload raises rigidity but tightens the allowable height error at 500 mm spacing from 170 um to 110 or 90 um, so the base machining must follow. Checklist: complete set, H square standard carriage, one block, 1880 mm rail, N accuracy, preload A as coded, M6 fitting, top-lock mounting; a spare part for a sister axis needs the pairing letter from its BK or RLX 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 LSH30HN1X1880S20AN-M6 FAQ
Dynamic C 37.4 kN, static C0 55.0 kN, static moments MR 0.66 / MP 0.67 / My 0.67 kN.m per carriage; N-grade running parallelism 12 to 37 um by rail length; M8 rail screws at 3040 / 2010 / 1470 N.cm for steel / cast iron / aluminium; Mobilux EP2 charge 5.4 cm3 per standard carriage with a 1.7 cm3 top-up every 100 km of travel or every 3 to 6 months, whichever comes first.
No - it maximizes mounting latitude. With preload A, size 30 allows 40 um of parallelism error and 170 um of height error between rails at 500 mm spacing, proportional to actual spacing. Ordering the same axis with light preload B tightens height to 110 um, medium C to 90 um. The self-aligning geometry absorbs only these slight errors, not unlimited misalignment, and how firmly the rail is drawn onto its datum influences the achieved accuracy as much as the accuracy grade does. Choose preload for stiffness only when the machining of the base can support it.
