Airtac LSH Linear Guide Rail LSH15HN2X260S10AH-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN2X260S10AH-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 LSH15HN2X260S10AH-M4
LSH15HN2X260S10AH-M4 is a matched size 15 set: one 260 mm rail with 10 mm end-hole offset, two square carriages of standard length, no preload, high accuracy and M4 fittings. The size code reads 15 and the rail genuinely is 15 mm wide. Four ball rows meet the 45 degree X raceways at two points per ball, giving equal rating in all four directions plus self-alignment that forgives small machining errors on the mounting face.
The high grade here keeps running parallelism inside a 7-28 um band, about a quarter tighter at the top end than the normal grade's 12-37 um. Each block rates 11.3 kN dynamic and 17.9 kN static with 0.12 kN.m moment ratings. Because the order carries no preload, installation tolerance stays generous: up to 130 um of height error between rails at 500 mm spacing, so a well-milled or cast base is good enough without grinding.

Where the Airtac LSH Linear Guide Rail LSH15HN2X260S10AH-M4 Is Used
Optical inspection microscope stage
The high grade holds running parallelism within 7-28 um over the 260 mm travel, enough for a benchtop vision system checking connector pins or solder joints.
Small-format laser engraver axis
A 260 mm stroke moves the lens carriage of a desktop engraver; two blocks stop the head rocking at each direction change and keep the beam spot on track.
Connector pin press fixture
A compact press fixture for crimping terminal pins rides a short twin-block guide; the 15 mm rail keeps the fixture footprint small on a crowded assembly bench.
Is the Airtac LSH Linear Guide Rail LSH15HN2X260S10AH-M4 the Right Guide?
Size the guide in both directions. Downwards: LRM serves light duties in a smaller envelope, and because its ratings are not published we will confirm them against your duty. Upwards: when a cantilever or offset mass makes moment, not load, the deciding figure, take LSH20 or a long carriage - on size 20 the long block lifts moment roughly 30 percent against a 19 percent gain in dynamic rating. Across: LGC fits short travels that need crossed-roller stiffness rather than recirculating travel.
Ordering checklist: confirm the form you need (set, carriage only or rail only), the size against load and moment, carriage style and length, how many blocks and what rail length, accuracy and preload and the mounting accuracy each demands, the grease fitting, and the pairing code when replacing one part of an existing guide.
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 LSH15HN2X260S10AH-M4 FAQ
For LSH15 with standard blocks, catalogue values are: dynamic rating C 11.3 kN per carriage, static C0 17.9 kN, static moments MR 0.12, MP 0.12 and My 0.12 kN.m. The high accuracy grade here runs at 7-28 um parallelism across the length bands. Mount with M4 screws at 412, 274 or 206 N.cm for steel, cast iron and aluminium beds. Grease capacity is 0.9 cm3 per block, topped up with 0.3 cm3 every 100 km or every 3 to 6 months.
Yes - the code LSH15HN2X260S10AH-M4 is a complete set: one 260 mm rail and two carriages, each with an M4 fitting. Carriages of a given LSH model are interchangeable with any rail of that model and keep their preload and accuracy, so a later replacement block needs no re-matching. Nothing here carries air; this is a mechanical rolling guide with no bore, stroke or pressure rating.
