Airtac LSH Linear Guide Rail LSH15BK-F1N-N-D-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15BK-F1N-N-D-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-F1N-N-D-M4
The code LSH15BK-F1N-N-D-M4 identifies a single carriage from the LSH standard guide family - an F1 top-flange block, standard length, accuracy grade N, lubricated by an M4 nipple, matched to rails via pairing code D. It ships without any rail. Lubrication is where this part lives day to day: AirTAC fills each block at the factory with 0.9 cm3 of Mobilux EP2 or equivalent, and service means topping up 0.3 cm3 through the nipple after roughly every 100 km of travelled distance, or every 3 to 6 months in calendar terms. Inside, four ball rows in 45 degree X-set raceways hold load capacity equal in every direction while the recirculating balls self-align to slight mounting error on a 15 mm wide rail.
The 100 km figure binds sooner than many buyers expect: a machine with a 300 mm stroke cycling once per second covers 100 km in about two weeks of continuous running, so distance, not the calendar, usually triggers the next top-up. After greasing, stroke the block through at least three of its own lengths, twice, and confirm an even film along the raceway. One caution that applies specifically to this flange style: side-mounted nipples are not recommended on flange blocks because the fitting can foul adjacent structure, so verify clearance on your machine before mounting.

Where the Airtac LSH Linear Guide Rail LSH15BK-F1N-N-D-M4 Is Used
High-cycle adhesive dispensing slide
A dispensing head on an electronics line sweeps 300 mm every cycle; at one cycle per second the block reaches its 100 km regrease point in about two working weeks, so the M4 nipple must stay accessible in the machine layout.
Print-head transport on a case coder
A case-coding machine drives its inkjet head across a 15 mm rail thousands of times per shift; a fresh factory-greased block restores quiet travel without disturbing the lubrication of the rest of the guide.
Tray handler on a pharma packaging line
A pharmaceutical packaging line shuttles trays over a short stroke continuously; re-greasing through the nipple during scheduled service keeps the 11.3 kN-rated block rolling between annual overhauls.
Is the Airtac LSH Linear Guide Rail LSH15BK-F1N-N-D-M4 the Right Guide?
Let the service plan drive the choice. If the duty cycle runs tens of metres per minute around the clock, budget the 0.3 cm3 top-up into maintenance windows and keep a spare block on the shelf. Lighter duty with a tighter envelope can step down to the LRM miniature family - we confirm its unpublished ratings per enquiry; short travel needing crossed-roller stiffness points across to LGC instead. If the applied moment approaches 0.12 kN.m, take LSH20 with its 0.27 kN.m MR rather than hoping a size 15 block copes. Order checklist: form is carriage only, no rail included; size 15 checked against both load and moment; F1 style, standard length; single block; accuracy N; M4 nipple with clearance verified on the flange; and pairing code D, which must equal the code on your rail. A defined preload requires a complete-set code - enquire if you need it stated.
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-F1N-N-D-M4 FAQ
Yes: dynamic C 11.3 kN, static C0 17.9 kN, moments MR, MP and My each 0.12 kN.m, running parallelism 12-37 um for normal accuracy, rail screws M4 at 412/274/206 N.cm on steel, cast iron and aluminium, first grease charge 0.9 cm3, top-up 0.3 cm3, interval 100 km of travel or 3 to 6 months. The factory fill is Mobilux EP2 or an equivalent; after topping up, cycle the block at least three carriage-lengths twice and confirm an even film.
No rail is included - BK in the code means carriage only, so a complete guide needs a separate LSH15RLX rail. The D in the fourth position of the specification is the pairing code: rails and carriages of the same model must share it. Because any LSH15 carriage fits any LSH15 rail of the matching code while keeping its smoothness and accuracy, you can renew a worn block on an installed rail without touching the rail alignment.
