Airtac LSH Linear Guide Rail LSH15HN1X220S20AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN1X220S20AN-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 LSH15HN1X220S20AN-M4
LSH15HN1X220S20AN-M4 is the economy configuration of the LSH size 15 guide: a complete set made up of one 220 mm hardened profile rail, a single standard-length square carriage and an M4 lubrication nipple. Rail width is a true 15 mm. Four ball rows contact X-placed 45 degree arc raceways, two points per ball, so the same rating applies whether the load presses down, lifts or pushes sideways, and slight misalignment of the mounting face is absorbed inside the carriage rather than turning into bind.
The figures to size from are 11.3 kN dynamic and 17.9 kN static per carriage, each with a 0.12 kN.m limit for MR, MP and My. The static rating runs about 1.6 times the dynamic one across LSH - yet the dynamic value governs travel life even though it is the smaller number. Normal accuracy gives a 12-37 um parallelism band, and the 220 mm rail keeps roughly 3.8 m of headroom under the 4040 mm maximum length for size 15.

Model Code: Airtac LSH Linear Guide Rail LSH15HN1X220S20AN-M4
| LSH | LSH Series Linear Guide. |
|---|---|

| N | Standard carriage. |
| 1X220 | 1 carriage on a 220 mm rail. |

Where the Airtac LSH Linear Guide Rail LSH15HN1X220S20AN-M4 Is Used
Packaging divert-gate slide
A divert gate sliding product off a snack-food conveyor lane: normal accuracy and preload A forgive a rolled-steel frame, and 11.3 kN dynamic is far above the gate's demand.
Label-head feed table
Indexing cartons under a labelling head on a rotary line, a steady reciprocating duty where the 100 km re-grease clock matters more than peak load - a 300 mm stroke cycling once a second reaches it in about two weeks.
Switchgear assembly fixture
A sliding fixture base for assembling terminal blocks, where the 17.9 kN static rating leaves reserve against an operator leaning on the work plate.
Is the Airtac LSH Linear Guide Rail LSH15HN1X220S20AN-M4 the Right Guide?
Start downward before committing: for light, compact duties an LRM roller guide may fit, but its load ratings are not published, so confirm them with us against your duty cycle. Where the stroke is short and crossed-roller rigidity is what you actually need, LGC is the cross-over. If a moment governs - a cantilevered tool, an offset load - step to LSH20, whose MR of 0.27 kN.m is well over double the 0.12 kN.m here, or take the long LSH15 carriage instead of bolting on more blocks. Order checklist: complete set; size 15 checked on load and moment; square standard carriage, one; 220 mm rail with 20 mm end holes; accuracy N, preload A; grease M4. Rail and carriage come matched, no pairing code needed.
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 LSH15HN1X220S20AN-M4 FAQ
Per carriage: C 11.3 kN dynamic, C0 17.9 kN static, MR 0.12 / MP 0.12 / My 0.12 kN.m. The normal accuracy grade runs at 12-37 um parallelism over the rail length. Mounting screws are M4 at 412 N.cm (steel), 274 N.cm (cast iron) or 206 N.cm (aluminium), and the mounting shoulder is H 3.5 / H1 3 / H2 4 mm with a corner radius of 0.5 mm maximum. Grease: 0.9 cm3 first charge, 0.3 cm3 top-up, every 100 km or 3 to 6 months.
The box holds the 220 mm rail with the square carriage already fitted, bolt caps for the rail screw holes and the M4 nipple on the block. Yes - LSH carriages are interchangeable within the model: a later LSH15 square carriage mounts on this rail and keeps its smoothness, accuracy and preload, so a worn block can be swapped without touching the rail. Quote the accuracy and preload letters from this code when ordering the spare.
