Airtac LSH Linear Guide Rail LSH15HN2X320S10AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN2X320S10AN-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 LSH15HN2X320S10AN-M4
Order code LSH15HN2X320S10AN-M4 breaks down as a complete LSH15 set with a 320 mm rail whose first mounting hole sits just 10 mm from each end, two square standard carriages, accuracy N, preload A (none) and M4 nipples. That close-to-the-end hole pattern suits bases where the carriage must reach almost to the rail extremity. Rail width is genuinely 15 mm at this size. The running system is four recirculating ball rows seating in 45 degree X-configured arc raceways with two contact points per ball, giving matched capacity in all four load directions and a self-aligning habit that forgives small machining errors on the seat.
Each of the two carriages is rated 11.3 kN dynamic, 17.9 kN static and 0.12 kN.m moment in roll, pitch and yaw. The 320 mm rail uses under 8 percent of the 4040 mm maximum length available in size 15, so the same configuration can be ordered far longer if the machine grows. Normal grade parallelism spans 12-37 um. Because there is no preload, the pair of rails tolerates 130 um of height mismatch over 500 mm spacing - the loosest installation window the size offers, which matters on welded or cast frames.

Where the Airtac LSH Linear Guide Rail LSH15HN2X320S10AN-M4 Is Used
Benchtop PCB pick-and-place gantry
A lightweight placement head on two of these 320 mm rails travels end to end; the S10 hole position lets the axis use nearly the full rail length without dead zones at either stop.
Drag-chain driven marking axis
Where a cable chain drags the carriage on a compact ink or laser marker, the two standard blocks share the side pull and the 15 mm rail keeps the head plate low.
Bolt-on slide for a machining fixture
Fixture builders face-mount this complete set under an elevating clamp table; the self-aligning carriages sit happily on a milled, not ground, base within the 130 um height allowance.
Is the Airtac LSH Linear Guide Rail LSH15HN2X320S10AN-M4 the Right Guide?
Start from the load path. If each carriage sees under 11.3 kN dynamic and the moments stay inside 0.12 kN.m, this size is right; if a load hangs off the end, step to LSH20, whose standard block lifts MR to 0.27 kN.m - about a 125 percent moment increase for one size change - or take a long LSH20 carriage at 0.35 kN.m when tipping is the governing failure mode. Light duties in cramped envelopes suit LRM miniature guides; note their catalogue publishes no load ratings, so we confirm suitability case by case. For short strokes needing crossed-roller stiffness, LGC is the better mechanical match than a long ball rail. Checklist: confirm you want the full set rather than a carriage alone; size by load and moment together; square H carriage, standard length; two blocks; 320 mm rail; N accuracy; no preload, with the 130 um height allowance it buys; M4 lubrication point. Pairing codes only matter when buying a single part to match existing hardware.
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 LSH15HN2X320S10AN-M4 FAQ
Per square standard carriage: C 11.3 kN dynamic, C0 17.9 kN static, MR / MP / My each 0.12 kN.m. N grade parallelism: 12 to 37 um across the rail. Fixing: M4 screws at 412 N.cm into steel, 274 N.cm cast iron, 206 N.cm aluminium, with the supplied caps seated flush so swarf stays out of the ball circuit. Lubrication: Mobilux EP2, 0.9 cm3 initial fill, 0.3 cm3 top-up per block every 100 km or 3-6 months. At high cycle rates the distance figure arrives first - a short-stroke axis can cover 100 km within weeks of continuous running.
Not if the mounting surface is honest about its errors. Grade A (no preload) on LSH15 accepts 130 um of height difference and 25 um of parallelism between rails at 500 mm spacing; light preload B shrinks those windows to 85 and 18 um, medium C to 35 and 13 um. This set has no preload, so it runs freeest and installs easiest, at the cost of slight play under reversing loads. Choose C only when the base can be machined to the 35/13 um figures - the catalogue is explicit that self-alignment absorbs only slight error within the stated limits, not unlimited misalignment.
