Airtac LSH Linear Guide Rail LSH15HN1X320S10AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN1X320S10AN-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 LSH15HN1X320S10AN-M4
AirTAC built this LSH15HN1X320S10AN-M4 as a ready-to-mount pair: a 320 mm profile rail of true 15 mm width plus one square, standard-length block. Inside the block, balls recirculate through four rows of X-angled arc raceways set at 45 degrees, each ball touching at two points. The result is identical capacity in every load direction and self-aligning behaviour that forgives minor flatness or alignment faults in the machine base. Normal accuracy (code N) and zero preload (code A) complete the specification, with mounting holes recessed 10 mm from the rail ends.
The working numbers for this size and carriage length are 11.3 kN dynamic and 17.9 kN static, with 0.12 kN.m allowed on the MR, MP and My axes alike. Note that static sits about 1.6 times above dynamic here, a ratio that holds across the range: size the axis on C for travel life and treat C0 as the limit for shock loads and clamped standstill. Normal grade parallelism spans 12-37 um, comfortably enough for packaging slides, feeders and handling units that do not close a micron-level positioning loop.

Where the Airtac LSH Linear Guide Rail LSH15HN1X320S10AN-M4 Is Used
Labeler head slide rebuild
When a print-and-apply labeler's head carriage develops play, a 320 mm set with a standard block restores the slide in one purchase. Normal grade accuracy suits head alignment done with a dial indicator.
Carton pusher guide
A pusher arm that diverts cartons off a conveyor works mostly sideways. The four-row 45 degree geometry gives the sideways direction the same 11.3 kN rating as the vertical, and 17.9 kN of static capacity absorbs stall cases.
Modular handling station axis
A builder of small indexing machines can drop this set into a station slide without rework: the block self-aligns to slight base error, and the M4 fitting accepts standard grease lines.
Is the Airtac LSH Linear Guide Rail LSH15HN1X320S10AN-M4 the Right Guide?
Decide the form first: this is a complete set, so both parts arrive together. If an existing machine only needs a new block, the carriage-only LSH15BK code is the economical route - about a quarter of the set price - provided the old rail is undamaged and you know its pairing letter. On sizing, check the moment figure, not just the load: cantilevered tooling is where 0.12 kN.m of moment capacity runs out first, and stepping to LSH20 lifts that to 0.27 kN.m, while a long LSH15 block adds moment capacity without changing the rail. Duty below what LSH15 offers points at the LRM miniature series, whose ratings we confirm because they are not published. Short travel with a need for crossed-roller rigidity is LGC territory. Before you commit, tick off: complete set or part, load and moment, carriage style and length, block count and rail length, accuracy and preload versus the mounting tolerance you can actually machine, grease fitting, and the pairing code for part replacement.
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 LSH15HN1X320S10AN-M4 FAQ
For one LSH15 standard block: C 11.3 kN dynamic, C0 17.9 kN static, moments MR, MP and My all 0.12 kN.m. Parallelism band for N grade: 12-37 um. Rail fixings: M4 screws, 412 N.cm torque in steel, 274 in cast iron, 206 in aluminium. Lubrication: 0.9 cm3 Mobilux EP2 per block on first fill, 0.3 cm3 per top-up, serviced every 100 km of travel or every 3 to 6 months. Grease suits speeds up to 60 m/min; where heat must be carried away, use oil at 30-150 cSt.
Only if the application needs a preloaded, stiffer fit. Without preload the catalogue permits 25 um parallelism and 130 um height error between rails at 500 mm spacing - the loosest setting in the series. Light preload B tightens those to 18 um and 85 um, medium C to 13 um and 35 um. Take the free-running fit when your base plate is conventionally milled; order preload only when vibration or overturning moments demand extra stiffness and you can hold the tighter tolerances.
