Airtac LSH Linear Guide Rail LSH15F1N1X225S20AH-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15F1N1X225S20AH-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 LSH15F1N1X225S20AH-M4
Order this code and you receive a matched LSH15 assembly: one 225 mm hardened rail with a single top-flange standard-length carriage, built to H high accuracy, preload A and an M4 grease point. The block carries four rows of recirculating balls whose 45 degree X raceways even out small flatness faults in the base plate, so a milled surface without scraping can still deliver a smooth slide. The size-15 rail measures 15 mm across.
H grade bounds running parallelism at 7-28 um, roughly half the drift of the same rail in N grade. Per-carriage ratings stay at 11.3 kN dynamic, 17.9 kN static and 0.12 kN.m per moment axis. Two practical assembly points: drive the supplied bolt caps fully into the rail counterbores so swarf stays out of the ball circuit, and torque the M4 screws to 412 N.cm in steel - pulling the rail flat against its datum does much of the work of hitting that parallelism band.

Where the Airtac LSH Linear Guide Rail LSH15F1N1X225S20AH-M4 Is Used
Measuring microscope X-feed
An H-grade slide beneath a toolroom or measuring microscope keeps the stage path inside the 7-28 um band so crosshair travel matches the digital readout.
Fast positioning slide on a laser marker
Shuttle a small marking head between two fixtures; the standard carriage starts and stops briskly under light loads while H grade holds the beam path true across the 225 mm travel.
Indicator bridge on a coupling alignment bench
Run a dial-indicator bridge around a pump and motor coupling; the flange takes an angled bracket, and the 0.12 kN.m MP and My limits cover a typical bracket overhang.
Is the Airtac LSH Linear Guide Rail LSH15F1N1X225S20AH-M4 the Right Guide?
Choose H over N when the slide feeds a measuring probe, an optical head or a laser, positions where a few um of wander shows in the output; pay for P only if the job genuinely needs the 3-21 um band. Duty lighter and envelope smaller? LRM is the step down, with unpublished ratings we will verify for you. Travel short and stiffness the priority? LGC crossed rollers are worth a look. If moment is the limiting factor, LSH20's 0.27 kN.m MR more than doubles this size's 0.12. Checklist: complete-set form, load and moment sizing, F1 top flange, standard length, one block, 225 mm rail with a 20 mm end offset, H grade, preload A, M4 fitting - and note the 4040 mm maximum leaves over 3800 mm of length growth if the machine is ever stretched.
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 LSH15F1N1X225S20AH-M4 FAQ
Each carriage is rated 11.3 kN dynamic and 17.9 kN static, with 0.12 kN.m available on every moment axis (MR, MP, My). H accuracy bounds running parallelism at 7-28 um depending on finished rail length. Mounting: M4 screws torqued to 412, 274 or 206 N.cm in steel, cast iron and aluminium. Lubrication: 0.9 cm3 of Mobilux EP2 or equivalent at commissioning, 0.3 cm3 at each re-grease, due every 100 km run or after 3-6 months.
The code here specifies preload A, so the block is assembled free of pre-stress. Adding light preload B or medium C raises stiffness but narrows the installation window: at 500 mm rail spacing the allowed height error S falls from 130 um to 85 um at B and 35 um at C, while parallelism P tightens from 25 to 18 to 13 um. Self-alignment absorbs error only inside these limits - beyond them the block binds rather than corrects.
