Airtac LSH Linear Guide Rail LSH15HN2X1350S20AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN2X1350S20AN-M4 is a standard-type profile linear guide on a 15 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 LSH15HN2X1350S20AN-M4
Where the axis is longer than the machine is clever, this set fits: LSH15HN2X1350S20AN-M4 is one continuous 1350 mm LSH profile rail with two standard-length square carriages running free of preload, normal accuracy grade, M4 grease fittings. It is a complete kit - rail and both blocks together, nothing else to source. The four rows of balls contact X-oriented 45 degree arc raceways at two points each, so a vertical load, a side load or an overturning moment all meet the same rated capacity, and minor imperfections in the bed are absorbed inside the carriage. The size 15 rail measures a true 15 mm across.
A 1350 mm rail sits far inside the 4040 mm maximum for this size, leaving room to extend travel later without changing series. Per block the catalogue gives C 11.3 kN, C0 17.9 kN and 0.12 kN.m in all three moment directions; with two blocks spaced along the rail, the pair carries twice the vertical load and the separation between them does the roll-resisting work. With no preload, the guide tolerates the widest mounting error of any grade: 25 um parallelism and 130 um height at 500 mm spacing.

Where the Airtac LSH Linear Guide Rail LSH15HN2X1350S20AN-M4 Is Used
Print and web inspection camera rail
A line-scan camera travelling 1.35 m beside a moving web needs a straight, low-drag path rather than a preloaded one. N grade parallelism of 12-37 um keeps the lens where the software expects it.
Conveyor diverter slide
A pusher arm crossing a 600 mm belt rides best on a guide without preload drag. Two spaced blocks carry the arm's overturning load, and the free-running carriage keeps actuator sizing small.
Long-stroke board handling gantry
Panel and board routers cycle metres per minute along the X axis. At speed the 100 km re-grease distance arrives quickly - a 300 mm stroke at one cycle per second covers it in about two weeks of continuous running.
Is the Airtac LSH Linear Guide Rail LSH15HN2X1350S20AN-M4 the Right Guide?
Long, lightly loaded travel is this configuration's home ground: no preload means the loosest installation tolerances and the lowest drag, which suits axes that run often but are not measuring anything. Drop to LRM when the load is small and the space smaller - its ratings are not published alongside LSH, so we confirm them from the datasheet on request. Choose LGC instead if the travel is short and stiffness matters more than stroke, because crossed rollers hold rigidity without needing long running length. If a cantilevered load drives the choice, remember one size up buys moment faster than extra blocks: LSH20 reaches MR 0.27 kN.m.
Before ordering, tick each item: complete set or parts, size against both C and the moment, square standard carriage, two blocks, 1350 mm rail cut, accuracy N, preload A, M4 fitting. For a replacement block on existing rail, the pairing code stamped on the original part is what matches them.
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 LSH15HN2X1350S20AN-M4 FAQ
Per standard-length square block: dynamic C 11.3 kN, static C0 17.9 kN, moment MR 0.12, MP 0.12, My 0.12 kN.m. N accuracy holds running parallelism within 12-37 um over the rail length. Rail fixing is M4 screws torqued to 412 / 274 / 206 N.cm on steel / cast iron / aluminium. Each block ships greased with Mobilux EP2: 0.9 cm3 charge, 0.3 cm3 top-up, repeat every 100 km of travel or 3 to 6 months.
The delivery holds the 1350 mm rail, two square carriages and the bolt caps that seal the screw holes - a complete set, not parts. This code is preload A, so you get the loosest tolerances: 25 um parallelism and 130 um height error allowed at 500 mm spacing. Choosing B would stiffen the axis against reversal but pull those limits to 18 um and 85 um, so the machine bed would need to be that much flatter.
