Airtac LSH Linear Guide Rail LSH30HN2X540S30BP-M6
The AirTAC Airtac LSH Linear Guide Rail LSH30HN2X540S30BP-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 LSH30HN2X540S30BP-M6
The AirTAC LSH30HN2X540S30BP-M6 is a complete linear guide set: one 540 mm LSH30 profile rail with two square compact carriages of standard length, an end-hole offset of 30 mm, a greased M6 fitting and accuracy grade N. Four rows of recirculating balls sit in X-arranged arc raceways at a 45 degree contact angle, so the set carries load equally up, down and sideways and absorbs slight mounting-surface error inside the carriage rather than binding. Note that the true rail top width is 28 mm even though the size code reads 30 - set out the mounting face from the datasheet dimensions.
Every standard-length LSH30 carriage on this rail is rated 37.4 kN basic dynamic and 55.0 kN basic static, with allowable moments of 0.66, 0.67 and 0.67 kN.m about MR, MP and My. Light preload B trades a little installation latitude for rigidity: at 500 mm rail spacing the allowable height error S falls from 170 um with no preload to 110 um, and the parallelism allowance P from 40 um to 30 um, so a machined rather than a milled base is worth considering before you commit to the preloaded version.

Where the Airtac LSH Linear Guide Rail LSH30HN2X540S30BP-M6 Is Used
Laser cutter gantry Y-axis
Two preloaded carriages under a 540 mm gantry beam keep the cutting head on path while resisting lift and roll; M8 fixing at 3040 N.cm into a steel bed seats the rail flat.
Coordinate measuring slide
An N-grade 28 mm rail with light preload gives a rigid base for a CMM-style measuring slide, provided the base plate is machined inside the 30 um parallelism allowance.
Bottle-filling transfer carriage
A filler machine transfer carriage riding two carriages on one 540 mm rail resists tipping, while the light preload damps vibration from the capping heads.
Is the Airtac LSH Linear Guide Rail LSH30HN2X540S30BP-M6 the Right Guide?
Size the axis on moment first: 0.66 kN.m per carriage decides more cantilever applications than the 37.4 kN dynamic rating does. If your duty is light and the envelope tight, LRM rollers from the same range are smaller, but their load ratings are not published, so we confirm them before you order. Where travel is short and you need crossed-roller rigidity, LGC is the cross-grade option. Stepping up to LSH35 raises MR to 1.05 kN.m for one size. Before ordering, tick the checklist: form (this is a complete set with rail and 2 carriages), size by load and moment, carriage style and length, count and rail length, accuracy and preload with the installation trade-off, grease fitting family, and the pairing code if you are replacing one half of an existing pair.
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 LSH30HN2X540S30BP-M6 FAQ
Per carriage: basic dynamic load rating C 37.4 kN, basic static C0 55.0 kN, allowable moments MR 0.66, MP 0.67 and My 0.67 kN.m. Running parallelism for N grade rails is 12-37 um depending on length. Rail fixing is M8 screws torqued to 3040 N.cm in steel, 2010 in cast iron and 1470 in aluminium. Each carriage arrives charged with 5.4 cm3 of Mobilux EP2; re-grease with 1.7 cm3 every 100 km of travel or every 3 to 6 months, whichever comes first.
On a 500 mm rail spacing this set tolerates a parallelism error P of 30 um and a height error S of 110 um between the two rails, scaled to your actual spacing. The same size without preload would allow 40 um and 170 um. Self-alignment absorbs only error inside these values - a badly flat-mounted rail loses the benefit no matter what the preload grade, so check the bed and torque the M8 screws evenly.
