Airtac LSH Linear Guide Rail LSH25HN1X1000S20AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH25HN1X1000S20AN-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 LSH25HN1X1000S20AN-M6
The LSH25HN1X1000S20AN-M6 is a complete guide assembly in one box: a single standard-length square carriage on a 1000 mm rail, plain finish, normal accuracy, no preload, with an M6 grease fitting. This is AirTAC's LSH25 size, whose rail actually measures 23 mm wide - worth checking before you machine the mounting face, because the 25 in the code is a size number, not a width. Inside the carriage, four ball rows run in crossed 45 degree arc grooves, so downthrust, uplift and side loads all meet the same rating, and small flatness errors in the mounting surface are soaked up rather than transferred as binding.
Rated figures for the block: 26.9 kN dynamic, 39.4 kN static, and 0.44 / 0.38 / 0.38 kN.m of moment capacity. Note that the static value sits near 1.5 times the dynamic one - size on C for travel life, not on the bigger C0. With preload A this is the forgiving version: the catalogue allows up to 130 um of height error across a 500 mm rail span, so a milled aluminium baseplate is usually good enough without grinding. The 1000 mm rail also leaves generous headroom below the 4040 mm maximum length for this size.

Model Code: Airtac LSH Linear Guide Rail LSH25HN1X1000S20AN-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. |
| 1X1000 | 1 carriage on a 1000 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 LSH25HN1X1000S20AN-M6 Is Used
Pick-and-place gantry axis
A single-block axis carrying a vacuum gripper between stacker stations suits the 26.9 kN dynamic rating and the relaxed 130 um height tolerance of the no-preload grade.
Lab autoclave loading slide
A slide racking sample baskets into a steriliser runs slow, intermittent duty, where grease lubrication covers speeds up to 60 m/min with no oil feed system needed.
Packaging carton pusher
A pusher squaring cartons on a conveyor rides a 1 m rail; the 39.4 kN static rating absorbs the shock when a jammed carton stops the pusher dead.
Is the Airtac LSH Linear Guide Rail LSH25HN1X1000S20AN-M6 the Right Guide?
If your load is modest and the envelope small, LRM runs lighter and cheaper, though its ratings are unpublished and need confirming with us case by case. Should the moment on your cantilever come within a third of 0.44 kN.m, either add a second carriage or move up to LSH30, whose standard block lifts MR to 0.66 kN.m; the long LSH25 carriage is another route, raising MR to 0.58 kN.m. For short strokes that demand crossed-roller stiffness, LGC is the cross-over candidate. Buying checklist: set, carriage or spare rail (this one is a set), size by load and moment together, H square block, one block on a 1000 mm rail, normal accuracy with no preload, M6 fitting - and since LSH carriages and rails of the same model are interchangeable, a later spare part only needs to match the model.
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 LSH25HN1X1000S20AN-M6 FAQ
For the standard-length block: 26.9 kN dynamic (C), 39.4 kN static (C0), moment limits 0.44 MR / 0.38 MP / 0.38 My in kN.m, and normal-grade running parallelism in the 12-37 um band. Fix the rail with M6 bolts at 1370 / 921 / 686 N.cm for steel, cast iron and aluminium beds. The carriage arrives pre-filled with 3.6 cm3 of Mobilux EP2 and takes 1.1 cm3 on top-up, due every 100 km of travel or 3 to 6 months - a 300 mm stroke cycling once per second covers 100 km in roughly two weeks, so the distance limit usually triggers before the calendar does.
One 1000 mm LSH25 rail with its matched square carriage, an M6 grease nipple fitted to the block, and bolt caps for the rail's mounting holes - a complete set, so no separate rail or carriage purchase is needed. Drive the plastic bolt caps fully into their counterbores (seat the cap, lay a flat plate over it, tap vertically with a plastic mallet) so swarf cannot reach the ball circuit, and prepare the mating surfaces to the shoulder dimensions: H 6.5, H1 5, H2 5 mm with a maximum 1 mm corner radius.
