Airtac LSH Linear Guide Rail LSH25HN1X160S20AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH25HN1X160S20AN-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 LSH25HN1X160S20AN-M6
A single-carriage LSH25 linear guide set in the square compact block style, standard length, on a 160 mm rail with an M6 grease fitting, no preload and N-grade accuracy. Like every LSH set it runs four rows of balls on X-angled arc raceways at a 45 degree contact angle, which is what gives it identical capacity radially, laterally and upward, plus enough internal compliance to tolerate minor machining errors on the mounting face. The 25 series rail is 23 mm wide.
If you are stepping up from LSH20 for an overhung load, the moment figures explain why: MR rises from 0.27 kN.m on LSH20 to 0.44 kN.m here, about 63 percent, for one size change, while dynamic capacity moves from 18.6 to 26.9 kN. This standard-length block is rated 26.9 kN dynamic, 39.4 kN static, and 0.44 / 0.38 / 0.38 kN.m across MR, MP and My. The 160 mm cut keeps the axis short but leaves ample room below the 4040 mm series maximum if a longer rail is needed later.

Model Code: Airtac LSH Linear Guide Rail LSH25HN1X160S20AN-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. |
| 1X160 | 1 carriage on a 160 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 LSH25HN1X160S20AN-M6 Is Used
Cantilevered inspection-camera boom
A camera arm overhung from the block face on an in-line inspection rig. MR 0.44 kN.m, up about 63 percent from LSH20, is the figure that keeps the boom from pitching under load.
Carton-ejector pusher guide
A pusher arm on a case-packing conveyor that kicks cartons onto a takeaway belt. The overhung pusher works against the moment rating, which is exactly why this stepped-up size was chosen.
Drill-press table cross-slide
A workshop cross-slide carrying a heavy vise under a pillar drill. The 23 mm rail bolts to an aluminium tooling plate with M6 screws at the 686 N.cm aluminium torque.
Is the Airtac LSH Linear Guide Rail LSH25HN1X160S20AN-M6 the Right Guide?
You are likely here because the moment rating ruled out a smaller series; check that against MR 0.44 kN.m and dynamic 26.9 kN before committing, and remember a long LSH25 block reaches 0.58 kN.m, while a second block addresses tipping along the travel rather than across it. If the job turns out lighter than expected, LRM steps down - ask us to confirm its ratings, which are not published - and if the travel is short with rigidity more important than reach, LGC's crossed rollers are the cross-over. Final match list: form (this is a complete set), size by load and moment jointly, square block, standard length, one carriage, 160 mm rail, accuracy N, preload A with its relaxed 130 um height allowance at 500 mm spacing, and the M6 grease fitting from the 20-to-35 fitting family.
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 LSH25HN1X160S20AN-M6 FAQ
Dynamic rating C 26.9 kN and static rating C0 39.4 kN per carriage. Static moment limits are MR 0.44, MP 0.38 and My 0.38 kN.m. N accuracy grade gives running parallelism in the 12-37 um band across the length range. The rail is fixed with M6 screws torqued to 1370 N.cm on steel, 921 N.cm on cast iron and 686 N.cm on aluminium, and each block leaves the factory with 3.6 cm3 of Mobilux EP2, topped up with 1.1 cm3 every 100 km of travel or every 3 to 6 months.
Yes. LSH carriages are interchangeable within the model: any LSH25 block fits any LSH25 rail and keeps its own smoothness, preload and accuracy, so a second square carriage ordered later will run on this 160 mm rail alongside the first. Two blocks on one rail are the standard fix for tipping along the direction of travel, and this rail length leaves room for the larger footprint. What the box contains today is one carriage on one rail, the M6 fitting already fitted and the rail's bolt-hole caps - nothing else is required to run it.
