Airtac LSH Linear Guide Rail LSH15HN1X220S20AH-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN1X220S20AH-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 LSH15HN1X220S20AH-M4
This code, LSH15HN1X220S20AH-M4, orders a complete matched LSH guide: a 220 mm size 15 profile rail carrying one compact square carriage of standard length, with an M4 grease fitting on the block. The rail is a true 15 mm wide. Four rows of recirculating balls meet the rail at a 45 degree contact angle in X-arranged arc raceways, two contact points per ball, which gives equal capacity up, down and sideways and lets the carriage absorb small errors in the mounting face without binding.
The H in the accuracy field is the meaningful upgrade here: high grade holds running parallelism to a 7-28 um band over the rail length, against 12-37 um for normal grade. Load figures are unchanged - 11.3 kN dynamic and 17.9 kN static per carriage, with 0.12 kN.m moment limits in all three directions. End mounting holes sit 20 mm from each rail end, and 220 mm leaves generous headroom below the 4040 mm maximum length for this size.

Where the Airtac LSH Linear Guide Rail LSH15HN1X220S20AH-M4 Is Used
Laser marking head slide
Moving a fiber laser marking head across small injection-moulded parts: the 7-28 um high-grade parallelism band keeps beam focus steady along the whole stroke.
Optical metrology carriage
Carrying an inspection camera along a fixture for dimension checks on machined housings, where normal-grade drift would show up as repeat-reading error.
Semiconductor test fixture
Indexing a probe board over connector samples in a test rack, a duty where the four-row 45 degree geometry must stay square under alternating side loads.
Is the Airtac LSH Linear Guide Rail LSH15HN1X220S20AH-M4 the Right Guide?
When straightness of travel, not raw capacity, decides the job, this H-grade set is the right step; if the duty is lighter still and the envelope smaller, compare LRM, whose load ratings are unpublished and need confirming with us. For short strokes needing crossed-roller stiffness, LGC is the alternative. Should the load cantilever, step to LSH20 or to a long LSH15 carriage rather than adding blocks - MR rises from 0.12 to 0.27 kN.m one size up. Before ordering, tick off: complete set form; size 15 verified for load and moment; square standard block, one; 220 mm rail, 20 mm end offset; high accuracy with preload A; M4 fitting. Carriage and rail arrive together, so no pairing code applies.
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 LSH15HN1X220S20AH-M4 FAQ
Per carriage: dynamic C 11.3 kN, static C0 17.9 kN, moments MR 0.12, MP 0.12 and My 0.12 kN.m. High (H) accuracy gives a 12-37 um... rather, a 7-28 um running-parallelism band. Rail screws are M4, torqued to 412 N.cm on steel, 274 N.cm on cast iron, 206 N.cm on aluminium. Lubrication is 0.9 cm3 first charge per carriage, 0.3 cm3 top-ups, re-greased every 100 km of travel or every 3 to 6 months, using Mobilux EP2 or an equivalent.
No. Accuracy grade sets how straight the carriage runs on a correctly mounted rail; preload sets how much mounting error the assembly forgives. With preload A you may tolerate roughly 130 um of height error and 25 um of parallelism between rails at 500 mm spacing. Ask for the same set with preload B and the height allowance drops to 85 um, with C to 35 um - rigidity is bought with installation latitude, so choose B or C only where the base plate is machined accordingly.
