Airtac LSH Linear Guide Rail LSH25HN1X1200S30AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH25HN1X1200S30AN-M6 is a standard-type profile linear guide on a 23 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 LSH25HN1X1200S30AN-M6
For a single-axis slide with real travel, LSH25HN1X1200S30AN-M6 pairs one standard-length square carriage with a 1200 mm stretch of LSH25 rail, normal accuracy, no preload, an M6 grease fitting, and 30 mm between the rail-end face and the first mounting hole at each end. Mind the geometry when drafting the baseplate: the size 25 rail is 23 mm wide, and the S30 end offset shifts the first hole line in from each rail end. The four-row, 45 degree crossed-raceway ball circuit gives the carriage the same rating whichever way the force points and lets it ride out slight misalignment in the machine bed.
The block itself carries 26.9 kN dynamic, 39.4 kN static and 0.44 / 0.38 / 0.38 kN.m of moment capacity. A 1200 mm rail sits comfortably inside the 4040 mm catalogue maximum for size 25, so shorter or longer cuts remain available if the layout changes. Without preload, installation is at its most tolerant - up to 130 um of height error across a 500 mm span - and if the axis later carries a heavier or overhung load, stepping up to LSH30 raises the moment rating about 50 percent, to 0.66 kN.m.

Model Code: Airtac LSH Linear Guide Rail LSH25HN1X1200S30AN-M6
| LSH | LSH Series Linear Guide. |
|---|---|
| 25 | Size code — note the rail is 23 mm wide, not 25 mm. |
| H / F1 / F2 / F3 | Carriage style: square, or flange mounted from the top, bottom, or both. |
| N | Standard carriage. |
| 1X1200 | 1 carriage on a 1200 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 LSH25HN1X1200S30AN-M6 Is Used
Cable-carrier test rig
A rig cycling energy chains over a metre of travel leans on the single block's 0.44 kN.m moment rating to carry the chain's overhung weight at mid-stroke.
Sorting-chute diverter arm
A warehouse diverter swinging parcels between chutes from a 1200 mm guide throws shock loads onto the 39.4 kN static rating rather than onto C.
Inspection dolly track
A video-inspection dolly gliding along machine frames rides the 1200 mm rail; the no-preload grade tolerates the modest flatness of a fabricated track beam.
Is the Airtac LSH Linear Guide Rail LSH25HN1X1200S30AN-M6 the Right Guide?
Long single-block axes live or die by the moment case: check the overhang from block centre to the load's centre of gravity against 0.44 kN.m before trusting the 26.9 kN dynamic figure. Light duty in a compact frame steps down to LRM (its ratings are unpublished, so we confirm them per application); short-travel, high-stiffness duty steps across to LGC; persistent overload steps up to LSH30 or to a two-block arrangement, which resists tipping along the rail. Order checklist: confirm this full set is the form you need, size by load and moment, square standard carriage, single block, 1200 mm rail with 30 mm end offset, normal accuracy with no preload and its 130 um height allowance, M6 fitting, and M6 screws torqued to 1370 N.cm on steel.
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 LSH25HN1X1200S30AN-M6 FAQ
Per standard-length carriage: 26.9 kN dynamic (C), 39.4 kN static (C0), moments 0.44 MR / 0.38 MP / 0.38 My kN.m, and normal-grade running parallelism within the 12-37 um band. Mounting: M6 screws at 1370 / 921 / 686 N.cm into steel, cast iron and aluminium respectively, with rail end holes starting 30 mm from each end. Grease: 3.6 cm3 Mobilux EP2 factory charge, then 1.1 cm3 top-ups every 100 km of travel or every 3 to 6 months.
The box holds the 1200 mm rail and its single matched square carriage with an M6 grease nipple, plus rail bolt caps - a complete set, nothing else to buy. For the layout: the rail is 23 mm wide despite the 25 size code, end holes sit 30 mm in from each rail end, mounting shoulders are H 6.5, H1 5 and H2 5 mm with a maximum 1 mm corner radius, and height error between rails should stay within 130 um over 500 mm of spacing since preload A carries the loosest tolerance. Tap the bolt caps flush below the rail top face so swarf stays out of the ball circuit.
