Airtac LSH Linear Guide Rail LSH25HN2X2100T2100AH-M6
The AirTAC Airtac LSH Linear Guide Rail LSH25HN2X2100T2100AH-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 LSH25HN2X2100T2100AH-M6
The T2100 segment in LSH25HN2X2100T2100AH-M6 marks a spliced rail: two factory-matched 2100 mm sections joined at the T interface into one continuous 4200 mm guide, carrying two standard square carriages with no preload, high accuracy and M6 grease fittings. Splicing is how the LSH range passes the 4040 mm single-piece limit for size 25, and the sections are matched at the works so a carriage crosses the joint without a bump. Four rows of balls at 45 degree X-set raceways give equal capacity in every direction plus self-alignment; the rail face is 23 mm wide, not 25.
Per carriage: 26.9 kN dynamic, 39.4 kN static, 0.44 / 0.38 / 0.38 kN.m for MR / MP / My. Two carriages spaced far apart along a 4200 mm bed also resist tipping along the travel, which is the real reason long machines run two or more blocks. With no preload the set tolerates 130 um height and 30 um parallelism error per 500 mm of spacing, and each section is ground to the H grade 7-28 um parallelism band. Keep the sections in their delivered order - if the guide is ever lifted out, re-assemble the joint exactly as matched.

Model Code: Airtac LSH Linear Guide Rail LSH25HN2X2100T2100AH-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. |
| 2X2100 | 2 carriages on a 2100 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. |

Where the Airtac LSH Linear Guide Rail LSH25HN2X2100T2100AH-M6 Is Used
Automated storage shuttle
A tote-handling shuttle running a 4 m aisle rides the full 4200 mm spliced rail; carriages at the shuttle corners stop the lifting mast from racking at either end of travel.
Print-and-apply labeller
A label applicator traversing alongside passing pallets needs more than 3 m of stroke; the spliced rail covers it where a one-piece LSH25 rail tops out at 4040 mm.
Granite beam scanner
A straightness probe travels the length of a 4 m granite reference beam; H-grade sections and a matched joint keep the sensor path smooth as it crosses the splice.
Is the Airtac LSH Linear Guide Rail LSH25HN2X2100T2100AH-M6 the Right Guide?
Go spliced when the stroke exceeds 4040 mm, the longest single rail AirTAC grinds for size 25; below that limit, order one piece for simpler alignment. If your travel is under about two metres, a single-piece LSH set is the simpler choice; if the duty is light and the envelope small, LRM may do, though its unpublished ratings mean we confirm them with you first; for short, stiff, crossed-roller motion, LGC is the alternative. Checklist for this code: form (complete set with jointed rail), size 25 with 23 mm rail width, two square standard carriages, 4200 mm total from two 2100 mm sections, accuracy H, preload A, M6 fitting. Replacing one carriage only? Quote the pairing code from the old block so the new one matches the 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 LSH25HN2X2100T2100AH-M6 FAQ
Total rail 4200 mm, made of two matched 2100 mm sections. Per carriage: dynamic 26.9 kN, static 39.4 kN, moments 0.44 / 0.38 / 0.38 kN.m (MR/MP/My); each section is ground to the H-grade 7-28 um parallelism band. Mounting: M6 screws at 1370 / 921 / 686 N.cm for steel / cast iron / aluminium. Grease per carriage: 3.6 cm3 first charge, 1.1 cm3 top-up, Mobilux EP2, every 100 km of travel or every 3 to 6 months. No preload: 130 um height and 30 um parallelism error allowed per 500 mm spacing.
The sections are factory ground and matched so the carriage crosses the joint smoothly, and splicing is the only way to pass the 4040 mm one-piece limit for size 25. You receive the two matched sections, both carriages pre-filled with grease, and bolt caps for the mounting holes. Rails and carriages must share the same model and pairing - an LSH carriage does not run on another maker's rail, so keep the sections in their delivered sequence and match any replacement block by pairing code.
