Airtac LSH Linear Guide Rail LSH30HN2X2680S20AN-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30HN2X2680S20AN-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 LSH30HN2X2680S20AN-M6
Order LSH30HN2X2680S20AN-M6 and you receive a complete guide: one 2680 mm rail in normal accuracy, two square standard carriages, no preload, with the bolt caps that protect the ball circuit. The carriage geometry - four ball rows contacting X-arranged 45 degree arc raceways at two points per ball - gives equal capacity in all four load directions plus a degree of self-alignment that forgives slight errors in a machined bed. Size 30 rides on a rail 28 mm wide.
The two carriages on one rail are what keep a long, wide bed from tipping as it travels, the pair sharing the 0.66 / 0.67 / 0.67 kN.m moment duty at 37.4 kN dynamic and 55.0 kN static each. Plan lubrication from day one: each standard size 30 carriage takes 5.4 cm3 of Mobilux EP2 at first charge and 1.7 cm3 at top-up, on a 100 km or three-to-six-month clock.

Model Code: Airtac LSH Linear Guide Rail LSH30HN2X2680S20AN-M6
| 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. |
| 2X2680 | 2 carriages on a 2680 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 LSH30HN2X2680S20AN-M6 Is Used
Woodworking CNC router beam
A router beam spanning a 2680 mm bed cuts sheet goods all day; twin carriages per rail resist the lifting and plunging moments of a cutter entering the panel.
Milling machine slide rebuild
Converting a worn dovetail slide on a knee mill to profile rail restores smooth feed; the square carriages bolt where the old gib ran, and the set format covers rail and blocks in one code.
Conformal coating reciprocator
A coating head reciprocates over loaded circuit-board panels; the four-row ball circuit keeps the nozzle path repeatable across a 2.7 m machine.
Is the Airtac LSH Linear Guide Rail LSH30HN2X2680S20AN-M6 the Right Guide?
For a machine bed approaching 2.7 m, check the mounting surface first: the tighter the preload, the less parallel and height error the guide forgives, and at this length a normal-grade rail with no preload is the forgiving pairing for typical machining. Downsize to LRM when the load is light and the envelope small - we will confirm its unpublished ratings with you; cross to LGC when the travel is short but crossed-roller rigidity is the priority. Order checklist: form - set, carriage or rail; size chosen on load and moment together; square or flange carriage, standard or long; carriage count and rail length; accuracy and preload with the installation trade-off stated; grease fitting; and the pairing code for replacement 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 LSH30HN2X2680S20AN-M6 FAQ
Each of the two standard square carriages carries 37.4 kN dynamic, 55.0 kN static and moment limits of 0.66 MR, 0.67 MP and 0.67 My in kN.m; the normal accuracy grade corresponds to a running parallelism of 12-37 um across the length bands. Rail screws are M8 at 3040 / 2010 / 1470 N.cm in steel, cast iron and aluminium. First grease charge is 5.4 cm3 per carriage, with 1.7 cm3 top-ups on the 100 km or 3-to-6-month interval.
The distance clock binds sooner than the calendar. A stroke of roughly 2.4 m on this rail means 4.8 m per cycle; cycling once every five seconds covers 100 km in about 29 hours of running. Each standard carriage holds 5.4 cm3 of grease at first charge and takes 1.7 cm3 at top-up, so keep a tube at the machine and re-grease by kilometres travelled, not by date. Meanwhile the figures to size against remain 37.4 kN dynamic and 55.0 kN static per carriage.
