Airtac LSH Linear Guide Rail LSH15HN2X380S10AH-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN2X380S10AH-M4 is a standard-type profile linear guide on a 15 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 LSH15HN2X380S10AH-M4
This LSH15HN2X380S10AH-M4 arrives as a complete linear guide assembly - one 380 mm profile rail 15 mm wide, carrying two square standard-length carriages - in high accuracy grade H with no preload, so the blocks run freest. Four rows of balls circulate through X-shaped 45 degree arc raceways with two-point contact per ball; that layout gives each carriage the same capacity in all four load directions and lets it self-align over minor mounting imperfections. The S10 in the code sets the first mounting hole 10 mm in from the rail end.
Grade H holds running parallelism within 7-28 um over the rail length band. Per carriage the catalogue lists 11.3 kN dynamic, 17.9 kN static and 0.12 kN.m in each moment direction MR, MP and My, with the two blocks sharing the duty on this single rail. Because there is no preload, the axis keeps its drag low and still tolerates a 130 um height difference across a 500 mm mounting span - a useful mix for a travel axis where straightness of the reading matters more than brute stiffness. At 380 mm the rail uses under a tenth of the 4040 mm length ceiling for size 15.

Model Code: Airtac LSH Linear Guide Rail LSH15HN2X380S10AH-M4
| LSH | LSH Series Linear Guide. |
|---|---|
| 15 | Size code. |
| H / F1 / F2 / F3 | Carriage style: square, or flange mounted from the top, bottom, or both. |
| N | Standard carriage. |
| 2X380 | 2 carriages on a 380 mm rail. |
| S… | End-hole offset from the rail end, in mm. |

Where the Airtac LSH Linear Guide Rail LSH15HN2X380S10AH-M4 Is Used
Granite-table measuring slide
A fixture slide on a granite surface plate carries workpieces past a dial or laser sensor; the 7-28 um grade H parallelism band keeps indicator drift low across the 380 mm stroke.
Wire cut-and-strip feed axis
The feed carriage of a wire-processing machine guides cable through its rollers; with no preload the block runs with minimal drag, helping the feed hold wire tension constant through every strip cycle.
High-cycle packaging diverter
A diverter arm on a confectionery packaging line switches lanes continuously; with a 300 mm stroke cycled once per second the 100 km re-grease distance arrives in about two weeks, so set the lubrication schedule by the travel counter, not the calendar.
Is the Airtac LSH Linear Guide Rail LSH15HN2X380S10AH-M4 the Right Guide?
Accuracy, not load, is the axis of this choice. Downward, LRM saves space on light duties but its load ratings are not published - we confirm them against your application on request. Upward, if the 7-28 um grade H band is more than the process needs, grade N on the same 380 mm layout costs less; if the moment governs instead, LSH20 N takes MR from 0.12 to 0.27 kN.m and the long LSH20 carriage buys more still, around 30 percent more moment for roughly 19 percent more dynamic rating. Short strokes that want crossed-roller stiffness point to LGC rather than a bigger LSH. Figures the catalogue does not state - base materials, weight, top speed - we will pull from the datasheet on request.
Run through the checklist before ordering: form (complete set - rail plus two carriages), size against load and moment, carriage style and length, block count and rail length, accuracy grade and preload with the trade-off each imposes on mounting tolerance, grease fitting (M4 family at size 15), and the pairing code when ordering a replacement carriage or rail.
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 LSH15HN2X380S10AH-M4 FAQ
Per carriage: C 11.3 kN dynamic, C0 17.9 kN static, and 0.12 kN.m allowable moment in each of MR, MP and My. Grade H running parallelism spans 7-28 um over the rail length band - tighter than the 12-37 um of normal grade. Rail fixing is M4 screws at 412 / 274 / 206 N.cm for steel, cast iron and aluminium beds respectively. Lubrication is Mobilux EP2: 0.9 cm3 first charge per carriage, 0.3 cm3 top-up every 100 km of travel or every 3 to 6 months.
Yes - this is a complete set: one 380 mm rail plus two square carriages, matched and running smoothly together. Nothing pneumatic is involved; there is no bore or pressure figure anywhere on this product. S10 is the distance from the rail end to the centre of the first mounting hole, 10 mm here. Carriages and rails are also available separately under codes carrying the BK and RLX markers, each with a pairing letter that rail and carriage must share.
