Airtac LSH Linear Guide Rail LSH15HN1X505S12.5AN-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15HN1X505S12.5AN-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 LSH15HN1X505S12.5AN-M4
LSH15HN1X505S12.5AN-M4 is a complete size 15 guide: one 505 mm profile rail plus one square, standard-length ball carriage riding it. The unusual segment here is S12.5 - the end-hole offset is 12.5 mm rather than the more common 20 mm, which moves the first and last mounting holes inboard. That matters whenever the rail must land on an existing drilled pattern. Rail width is 15 mm, and the four-row X-arranged 45 degree ball circuits give equal capacity in all four directions with self-alignment inside the block.
Ratings per carriage: 11.3 kN dynamic, 17.9 kN static, and 0.12 kN.m of allowable static moment in each of the MR, MP and My directions, all at N accuracy with 12-37 um running parallelism. At 505 mm the rail sits far below the 4040 mm maximum length for size 15, so a shorter or longer cut on the same carriage footprint is straightforward to quote if the machine layout changes.

Where the Airtac LSH Linear Guide Rail LSH15HN1X505S12.5AN-M4 Is Used
Retrofit onto a drilled baseplate
A packaging machine rebuilt around an existing hole pattern: the 12.5 mm end offset places the first and last M4 holes where the old rail sat, so the frame needs no redrilling.
Small CNC router upgrade
A hobby CNC router gantry converted from round shaft to profile rail: 15 mm rail width, 505 mm of travel and a square carriage take the spindle's side loads without frame surgery.
Cartoning machine pusher guide
A carton-pusher slide on a small food packaging line: equal load ratings in all four directions let the carriage absorb both the downstroke and the side thrust of each push cycle.
Is the Airtac LSH Linear Guide Rail LSH15HN1X505S12.5AN-M4 the Right Guide?
If the duty is genuinely light and space is scarce, drop to LRM; its load ratings are not published, so ask us to confirm them against your cycle. If the stroke is short and the job wants the rigidity of crossed rollers more than long recirculating travel, move across to LGC. If the moment governs - an overhung sensor, a side-loaded tool - step up one size: LSH25 N takes MR from 0.12 to nearly 0.44 kN.m, close to a fourfold gain, whereas a second carriage on this same rail addresses tipping along the direction of travel instead.
Fit checklist: the form is a complete set; the size is chosen on load and moment together; carriage is square and standard length; one carriage sits on a 505 mm rail whose 12.5 mm end offset matches your hole pattern; accuracy is N; preload is A, which keeps the 130 um height-error allowance at 500 mm spacing; the grease fitting is M4; and after torquing the M4 screws, drive the bolt caps flush so swarf stays out of the ball circuit.
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 LSH15HN1X505S12.5AN-M4 FAQ
Catalogue values per standard carriage: dynamic C 11.3 kN, static C0 17.9 kN, static moment limits MR 0.12 kN.m, MP 0.12 kN.m and My 0.12 kN.m. Running parallelism at N accuracy spans 12-37 um. Mounting: M4 screws torqued to 412 / 274 / 206 N.cm for steel, cast iron and aluminium plates respectively, with a 0.5 mm maximum corner radius at the shoulders. Grease: 0.9 cm3 initial fill, 0.3 cm3 recharges through the M4 fitting, repeated every 100 km of travel or every 3 to 6 months.
This set ships with preload A, so at 500 mm rail spacing you may run up to 25 um of parallelism error and 130 um of height error between the two rails. Choose preload B and the height allowance halves to 85 um; choose C and it falls to 35 um, with parallelism down to 13 um. The self-aligning feature absorbs only these slight errors - it is not a substitute for machining the seats when a stiffer, preloaded guide is ordered.
