Airtac LSH Linear Guide Rail LSH30HN2X3950T2410AH-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30HN2X3950T2410AH-M6 is a standard-type profile linear guide on a 28 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 LSH30HN2X3950T2410AH-M6
This code is a complete LSH30 guide set built around a 3950 mm rail delivered in spliced sections, with the joint position coded at T2410 and bottom-lock mounting. Two standard-length square blocks ride the rail, greased through M6 fittings, with no preload and H (high) accuracy. The four-row ball circuit sits at a 45 degree contact angle in X-shaped arc raceways, giving equal capacity in all four directions and letting the carriages self-align over small datum errors. Despite the 30 in the part number, the true rail width is 28 mm - a 2 mm trap when machining the seat.
3950 mm leaves just 80 mm below the 4030 mm maximum rail length for size 30, so this is close to the longest single guide the series offers. Each carriage carries 37.4 kN dynamic and 55.0 kN static, with MR 0.66 kN.m, and the two-block layout resists tipping along nearly four metres of travel. The H grade keeps running parallelism inside 7-28 um over the band, which is what a long gantry needs if the far end is to meet the near end.

| LSH | LSH Series Linear Guide. |
|---|---|
| 30 | Size code — note the rail is 28 mm wide, not 30 mm. |
| H / F1 / F2 / F3 | Carriage style: square, or flange mounted from the top, bottom, or both. |
| N | Standard carriage. |
| 2X3950 | 2 carriages on a 3950 mm rail. |

Where the Airtac LSH Linear Guide Rail LSH30HN2X3950T2410AH-M6 Is Used
Full-sheet CNC router gantry
A 3950 mm axis spans a full 8 ft sheet of plywood or aluminium with room to spare, the two blocks sharing the load along nearly four metres of travel.
Storage and retrieval machine
An ASRS shuttle running a long aisle guide, where the spliced rail reaches almost the 4030 mm maximum for size 30 and the T2410 joint keeps handling practical.
Long-bed cutting table with energy chain
Plasma or knife cutting tables where the drag chain and the guide share the full travel, and bottom-lock rail mounting keeps the top face clear for swarf shedding.
Is the Airtac LSH Linear Guide Rail LSH30HN2X3950T2410AH-M6 the Right Guide?
On a rail this long, check the moment budget before the load: 0.66 kN.m MR per carriage, effectively doubled by running two blocks, covers most gantry heads, but a heavy cantilevered bridge may want the LSH30L long block at 0.88 kN.m. For a light, compact duty the LRM series is the smaller step, though its load ratings are unpublished and we confirm them case by case; for short travel needing crossed-roller stiffness, LGC is the crosswise alternative. Your match checklist: form (complete set: rail plus two carriages), size by load AND moment, carriage style and length, count and rail length including the splice position, accuracy H and preload A with the mounting trade-off, M6 grease fitting, and the pairing code only when ordering spare parts.
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 LSH30HN2X3950T2410AH-M6 FAQ
Each standard-length square carriage is rated 37.4 kN dynamic C, 55.0 kN static C0, with moments 0.66 MR / 0.67 MP / 0.67 My kN.m. Accuracy is H grade: running parallelism within 7-28 um across the rail-length band. Fix the rail with M8 screws at 3040 / 2010 / 1470 N.cm in steel / cast iron / aluminium. Grease: 5.4 cm3 first charge and 1.7 cm3 top-up per carriage via the M6 fitting, repeated every 100 km of travel or every 3 to 6 months, whichever comes first.
The rail arrives in sections with the joint coded at T2410 and uses bottom-lock mounting, so the fixing screws sit underneath and the top raceway face stays unbroken. Butt the sections squarely and torque the M8 screws correctly - whether the rail is pulled flat against the datum face largely decides the achieved accuracy - then drive the supplied bolt caps into the holes with a plastic mallet over a flat plate, seated flush with the rail top, or swarf will reach the ball circuit.
