Airtac LSH Linear Guide Rail LSH15BK-F2N-P-C-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15BK-F2N-P-C-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 LSH15BK-F2N-P-C-M4
A single LSH15 F2 carriage in precision grade: flange mounting from underneath, standard body length, M4 nipple for greasing. This listing is the block by itself - the profile rail is not part of the order. Inside, balls recirculate through four rows of X-arranged 45 degree raceways with two contact points per ball, so downward, lift-off and side loads all land on the same rating, and small datum errors are absorbed rather than forced into a bind. The LSH15 size runs on a rail 15 mm wide.
On paper: 11.3 kN dynamic, 17.9 kN static, 0.12 kN.m on all three moment axes. The static-to-dynamic ratio near 1.6 is why short-stroke shock loads rarely trouble this size, while travel life follows C. P grade holds running parallelism between 3 and 21 um across the rail-length bands. As a carriage-only purchase it costs roughly a quarter of a complete set, which is why a worn block is usually renewed rather than the whole guide.

Where the Airtac LSH Linear Guide Rail LSH15BK-F2N-P-C-M4 Is Used
Wafer probing station carriage swap
Probe stations in a university cleanroom are rebuilt block by block. This precision-grade carriage replaces a scored unit without touching the matched rail, provided the pairing letter C on both parts agrees.
LED inspection camera gantry
A camera riding above the guide needs the top surface; the F2 flange mounts from underneath so the lens plate bolts straight on. Moment ratings of 0.12 kN.m on every axis carry the cantilevered head.
High-cycle pick-and-place head
An axis with a 300 mm stroke cycling once per second covers 100 km in about two weeks, so the distance-based regrease interval binds long before the calendar - one more reason a serviceable M4 nipple on a spare block earns its keep.
Is the Airtac LSH Linear Guide Rail LSH15BK-F2N-P-C-M4 the Right Guide?
Start with the form: this is carriage only, so it suits a repair or a build where the rail already exists. Size on both load and moment - for a cantilever the MR figure usually decides, and moving to an LSH20 block buys moment capacity faster than it buys dynamic rating. Light-duty compact machines can drop to LRM, whose ratings are unpublished and confirmed by us per application; short-travel axes wanting crossed-roller stiffness can cross to LGC instead.
Checklist for the order: F2 bottom flange, standard length, P accuracy, M4 fitting, and pairing code C appearing on both block and rail. Remember preload is only an option on complete set codes, and a tighter grade always costs installation latitude on the mounting surface.
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 LSH15BK-F2N-P-C-M4 FAQ
C is 11.3 kN and C0 is 17.9 kN per block; the moment ratings read 0.12/0.12/0.12 kN.m for MR/MP/My. Running parallelism for P grade lies in the 3-21 um band. Use M4 screws torqued to 412 N.cm (steel), 274 N.cm (cast iron) or 206 N.cm (aluminium). Grease holds 0.9 cm3 new and takes 0.3 cm3 at re-fill; service it at 100 km of travel or every 3-6 months, whichever comes first.
Nothing but the carriage ships on this code - there is no rail in the box. The pairing letter C ties this block to a rail carrying the same letter, so quote the code printed on your old carriage or rail when ordering. Interchangeability runs within LSH only: a C-coded LSH15 block will not mate with another maker's 15 mm rail.
