Airtac LSH Linear Guide Rail LSH25HN1X145S10AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH25HN1X145S10AN-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 LSH25HN1X145S10AN-M6
This is a matched rail-and-carriage assembly from AirTAC's LSH series: a single compact square block, standard length, on a 145 mm profile rail, normal accuracy, preload code A meaning none, lubricated through an M6 nipple. The four-row ball circuit contacts X-shaped raceways at 45 degrees from two directions, giving the same load rating in every direction and letting the block absorb slight datum errors in its own internal clearance rather than fight them.
For layout work, the numbers that matter here are the shoulders: H 6.5 mm, H1 5 mm, H2 5 mm, with a mounting-surface corner radius of 1 mm maximum, and M6 rail screws torqued to 1370 N.cm in steel, 921 in cast iron or 686 in aluminium. The S10 offset puts the first fixing hole just 10 mm from the rail end, which helps on frames where hole positions are already set. At 145 mm, this rail uses only a small fraction of the 4040 mm maximum length the series can be cut to.

Model Code: Airtac LSH Linear Guide Rail LSH25HN1X145S10AN-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. |
| 1X145 | 1 carriage on a 145 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 LSH25HN1X145S10AN-M6 Is Used
Glue-dispensing gantry axis
The Y axis of a two-axis gantry laying a bead of sealant around automotive gaskets. The S10 end offset lets the rail sit close to the frame end plate where the stroke is short.
Divert-gate pusher slide
A linear slide pushing a divert gate across a bottling-line conveyor between two lanes. Preload-free running keeps drag low so the push force stays predictable for the gate drive.
Laser focus-axis slide
Raising and lowering a cutting head's focus carriage on a CO2 laser. N-grade accuracy with a 12-37 um running parallelism band is ample where the stroke is tens of millimetres.
Is the Airtac LSH Linear Guide Rail LSH25HN1X145S10AN-M6 the Right Guide?
Before ordering, verify the mounting surface, because on size 25 the rail is 23 mm wide and the datum shoulders are 6.5 mm high with a corner radius capped at 1 mm. If the duty is genuinely light and a smaller envelope would do, LRM is the step-down option - its ratings are not published, so ask us to confirm them - and for short-travel work needing crossed-roller stiffness rather than recirculating travel, LGC fits instead. Step up to a long carriage or to LSH30 when the moment rating, not the 26.9 kN dynamic load, is the binding constraint. Match list: set, carriage or rail form; size against load and moment; block style (square here) and length; block count and rail cut; accuracy N versus H or P; preload and the tightening it imposes on installation error; the M6 fitting; and, if you are replacing a block on an existing LSH25 rail, the pairing letter off the original 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 LSH25HN1X145S10AN-M6 FAQ
The standard block is rated C 26.9 kN dynamic and C0 39.4 kN static, with moment limits of 0.44 kN.m about MR and 0.38 kN.m about both MP and My. N-grade running parallelism falls between 12 and 37 um over the length range. Fix the rail with M6 screws to 1370, 921 or 686 N.cm on steel, cast iron or aluminium, and note the shoulder heights H 6.5 mm, H1 5 mm, H2 5 mm with a corner radius no greater than 1 mm. Grease per block: 3.6 cm3 first charge, 1.1 cm3 top-up, refreshed every 100 km or 3 to 6 months.
The 25 is the series number, not the rail dimension. On this series the rail section measures 23 mm across, and only at LSH45 do series number and rail width coincide. Lay out the mounting surface from the 23 mm figure and the 6.5 mm shoulder, not from the code, or the datum will sit 2 mm off. The S10 in the code is the distance from the rail end to the first mounting hole, set here at 10 mm.
