Airtac LSH Linear Guide Rail LSH30HN2X360S20AP-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30HN2X360S20AP-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 LSH30HN2X360S20AP-M6
LSH30HN2X360S20AP-M6 is a complete LSH30 linear guide set: a 360 mm profile rail carrying two standard-length square carriages, ordered with the S20 end-hole offset, an M6 grease fitting, no preload and the P (precision) accuracy grade. Four rows of balls run in X-arranged 45 degree arc raceways with two-point contact per ball, so capacity is equal up, down and sideways, and slight mounting-surface error is absorbed inside the carriage instead of binding the slide. Note for the machinist: the size code says 30 but the rail is 28 mm wide.
Per carriage the catalogue rates this size at 37.4 kN dynamic, 55.0 kN static and 0.66 / 0.67 / 0.67 kN.m in MR / MP / My. With two carriages sharing the rail, tipping loads along the travel are split between them. The precision grade holds running parallelism within 3-21 um across the band, and on a 360 mm rail you sit near the tight end of that band - this is the grade to specify when the measuring stage or machine tool itself sets the tolerance.

Model Code: Airtac LSH Linear Guide Rail LSH30HN2X360S20AP-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. |
| 2X360 | 2 carriages on a 360 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. |
| 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 LSH30HN2X360S20AP-M6 Is Used
CMM inspection stage
A 360 mm measuring axis on a coordinate measuring machine or vision inspection system, where the P grade's 3-21 um parallelism band keeps probe repeatability traceable.
Jig boring and grinding tables
Precision machine-tool tables in the 300-400 mm travel class, where the machinist, not the guide, sets the tolerance and the rail seat must be cut 28 mm wide.
Semiconductor inspection stage
Wafer and flat-panel inspection equipment needing straight, low-friction travel over 360 mm, with two blocks stiffening the stage against pitch.
Is the Airtac LSH Linear Guide Rail LSH30HN2X360S20AP-M6 the Right Guide?
Size this guide on moment as much as load: 0.66 kN.m MR per block is the figure a cantilever will find first, and if it is marginal, the LSH30L long block (45.7 kN C, 0.88 kN.m MR) is the next step within the same size rather than a bigger rail. If the duty is light and the envelope tight, step down to AirTAC LRM - its load ratings are not published, so we confirm suitability for you before you order. Where travel is short and the job wants crossed-roller rigidity rather than long recirculating travel, step across to LGC instead. Before ordering, check off: form (this is a complete set, rail and two blocks), size against both C and MR, carriage style and length, block count and rail length, accuracy and preload with the installation trade-off, grease fitting (the M6 family serves sizes 20 to 35), and the pairing code if you are ever buying parts to match existing 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 LSH30HN2X360S20AP-M6 FAQ
Per standard-length carriage: dynamic C 37.4 kN, static C0 55.0 kN, moments 0.66 MR / 0.67 MP / 0.67 My kN.m. The P (precision) accuracy grade holds running parallelism to 3-21 um across the rail-length band. Mount with M8 screws torqued to 3040 N.cm in steel, 2010 in cast iron, 1470 in aluminium. Each carriage ships pre-filled with 5.4 cm3 of Mobilux EP2; top up 1.7 cm3 through the M6 fitting every 100 km of travel or every 3 to 6 months.
Preload grade A gives the fitter the widest tolerances: at 500 mm rail spacing the size allows 40 um parallelism error and 170 um height error, scaling with actual spacing. Ordering light preload B instead would tighten those to 30 and 110 um, medium C to 27 and 90 um. So this no-preload set is the easiest LSH30 to install, at the cost of the lowest rigidity under vibration and reversing loads.
