Airtac LSH Linear Guide Rail LSH30HN2X700S30BP-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30HN2X700S30BP-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 LSH30HN2X700S30BP-M6
The LSH30HN2X700S30BP-M6 pairs a 700 mm LSH30 profile rail, offset 30 mm at the end holes, with two square standard-length carriages under accuracy grade N and light preload B. Two blocks spread across that 700 mm span do more than add capacity: spaced carriages resist tipping along the direction of travel, which is what usually fails a cantilevered or overhung load. The raceways are four rows of balls at 45 degree X-arrangement, equal-rated in every direction and self-aligning within limits. Rail top width is 28 mm, not the 30 the code suggests.
Moment is where this set earns its keep - 0.66 kN.m of MR per carriage - and lubrication is what keeps it there. Each carriage ships with 5.4 cm3 of Mobilux EP2 and takes 1.7 cm3 on top-up every 100 km or 3 to 6 months. That distance comes round quickly: a 300 mm stroke cycling once per second covers 100 km in roughly two weeks of continuous running, so on busy machines the distance binds well before the calendar.

Model Code: Airtac LSH Linear Guide Rail LSH30HN2X700S30BP-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. |
| 2X700 | 2 carriages on a 700 mm rail. |
| S… | End-hole offset from the rail end, in mm. |
| B | B — light preload — higher preload raises rigidity and tightens how flat the mounting surface must be. |
| P | P — precision 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 LSH30HN2X700S30BP-M6 Is Used
CNC router gantry carriage
A shop router gantry over 700 mm travel with two preloaded blocks keeps the spindle from rolling under side cuts; 0.66 kN.m per block covers typical router moment loads.
High-cycle pick-and-place unit
A pick-and-place arm cycling once a second racks up 100 km of travel in about two weeks; the 5.4 cm3 charge and 1.7 cm3 top-up schedule keeps the raceways fed at that pace.
Woodworking machine slide rebuild
Replacing a worn slide on a spindle moulder or panel saw with a 700 mm preloaded set restores rigidity; check the rebuilt table meets the 30 um parallelism allowance at 500 mm before fitting.
Is the Airtac LSH Linear Guide Rail LSH30HN2X700S30BP-M6 the Right Guide?
If the load hangs off the carriage rather than sits on it, work from the 0.66 kN.m moment rating and the two-block spacing before you look at the 37.4 kN dynamic figure. Need more reach without more width? A long LSH30 carriage lifts MR to 0.88 kN.m. LRM is the compact step down for lighter axes, though we confirm its unpublished ratings first; LGC suits short-stroke work needing crossed-roller rigidity. Before ordering check: form (complete set, rail plus 2 carriages), size by load and moment, carriage style and length, count and 700 mm rail length, accuracy N and preload B with its tighter mounting tolerance, grease fitting, and the pairing code when replacing a single part.
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 LSH30HN2X700S30BP-M6 FAQ
Per carriage: C 37.4 kN dynamic, C0 55.0 kN static, moments MR 0.66 / MP 0.67 / My 0.67 kN.m, running parallelism 12-37 um at N grade. Rail screws are M8 at 3040 N.cm (steel), 2010 (cast iron), 1470 (aluminium). Grease: 5.4 cm3 Mobilux EP2 factory charge, 1.7 cm3 top-up every 100 km of travel or every 3 to 6 months, whichever comes first.
Yes. Preload B stiffens the guide but narrows the window: at 500 mm between rails the allowed height offset S is 110 um and parallelism P is 30 um, against 170 um and 40 um for a grade A set of the same size. Scale to your real spacing, check the bed for flatness before fitting, and torque the M8 screws evenly - a rail not pulled flat loses accuracy regardless of preload.
