Airtac LSH Linear Guide Rail LSH15HN1X450S15AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN1X450S15AN-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 LSH15HN1X450S15AN-M4
A 450 mm rail on a size 15 guide sits comfortably inside the 4040 mm maximum length AirTAC publishes for LSH15, so this code is a standard cut rather than a special order. It arrives as one 450 mm precision profile rail with a 15 mm end-hole offset and a single square, standard-length carriage riding on it - a complete set, ready to bolt down. Ball recirculation runs over four rows in 45 degree X-shaped raceways, and any LSH15 carriage fits any LSH15 rail of the model while keeping its smoothness, preload and accuracy.
The ratings belong to the carriage: 11.3 kN dynamic (C) and 17.9 kN static (C0), with 0.12 kN.m per moment direction. Static runs at roughly 1.5 times dynamic across the whole LSH range, and buyers who size on the bigger C0 figure oversize the guide - C is what governs travel life. If the load overhangs the carriage, step up to a long LSH15 carriage or to LSH20, whose standard block raises MR to 0.27 kN.m.

Where the Airtac LSH Linear Guide Rail LSH15HN1X450S15AN-M4 Is Used
Bench lathe cross-slide retrofit
A hobby machinist converts a worn cross-slide to a 450 mm LSH15 axis, shimming the mount within the 130 um height allowance of preload A before final torquing, then trams the tool under power.
ATE board-handling slide
A test-head slide inside an electronics rack uses the 450 mm rail to present boards to successive sockets. The M4 fitting keeps the lubrication point clear of the cabling loom above the carriage.
Label applicator head rail
A pressure-sensitive label head reciprocates 450 mm across cartons on a packing line. Equal load capacity in all four directions handles the down-thrust of the tamp pad without a second guide.
Is the Airtac LSH Linear Guide Rail LSH15HN1X450S15AN-M4 the Right Guide?
Rail length is free to choose on LSH: 450 mm is one cut among many between short stubs and the 4040 mm maximum for size 15, so match rail length to your stroke and end stops rather than to a fixed list. If the duty is lighter and the envelope smaller, LRM steps down - its load ratings are not published, so we confirm them before you order. Short travel with a demand for crossed-roller rigidity points to LGC instead. If moment governs, the long LSH15 carriage or LSH20 (MR 0.27 kN.m against 0.12 here) is the step up.
Checklist: form (set, carriage or rail), size chosen on load and moment together, style H/F1/F2 and length N/L, block count, accuracy grade N/H/P, preload set against the installation tolerance you can hold, an M4-family grease fitting for size 15, and the pairing code if this replaces a part.
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 LSH15HN1X450S15AN-M4 FAQ
Dynamic C 11.3 kN and static C0 17.9 kN per carriage. Moments MR 0.12, MP 0.12 and My 0.12 kN.m. Accuracy N parallelism band 12-37 um. Rail mounting screws M4 at 412/274/206 N.cm for steel/cast iron/aluminium mounting plates. Lubrication: 0.9 cm3 grease at first charge, 0.3 cm3 at each top-up, repeated every 100 km of travel or every 3 to 6 months; the carriage arrives pre-filled with Mobilux EP2.
One 450 mm rail with a 15 mm end offset, one square standard-length carriage fitted to it, the specified M4 grease fitting, and plastic bolt caps for the screw holes. The caps matter: drive each into the counterbore, lay a flat plate over it and tap vertically with a plastic mallet, then clean the rail. A cap left standing above the rail top face - or a hole left open - lets swarf into the ball circuit and shortens the guide's running life.
