Airtac LSH Linear Guide Rail LSH15BK-F1N-H-D-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15BK-F1N-H-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-H-D-M4
A single top-flange block for a 15 mm wide profile rail is the whole of LSH15BK-F1N-H-D-M4. Carriage only, no rail leaves under this code: high accuracy grade, standard length, and a pairing letter D that locks it to the matching D rail. The design uses four rows of recirculating balls in X-arranged arc raceways at a 45 degree contact angle, two contact points per ball, so downward load, side load and moment capacity all come out level, and slight misalignment in the mounting surface is taken up inside the carriage.
Lubrication is where this part earns its keep: it arrives charged with 0.9 cm3 of Mobilux EP2 and wants 0.3 cm3 topped up every 100 km of travel or every 3 to 6 months. That interval is shorter than it sounds, since a 300 mm stroke cycling once per second covers 100 km in about two weeks of continuous running, so the distance binds before the calendar does. Ratings behind the block: 11.3 kN dynamic, 17.9 kN static and 0.12 kN.m moment in each of MR, MP and My. Because this is a flange-type carriage, do not fit a side grease nipple where it could foul the body; check the fitting position first.

Where the Airtac LSH Linear Guide Rail LSH15BK-F1N-H-D-M4 Is Used
Flow-wrapper jaw guide
A flow-wrapper's sealing jaw slides twice per package; the pre-filled 0.9 cm3 grease charge and the 100 km re-grease rhythm keep this code D block running without daily attention.
Capping head on a bottling line
A bottling line's capping head begins to rock on a worn 15 mm carriage; swapping in this pairing D block, same flange footprint, restores the fit without touching the rail.
High-cycle sorting pusher
A sorter pusher cycling once per second accumulates 100 km of travel in roughly two weeks, so the grease interval, not the calendar, sets the maintenance date on this block.
Is the Airtac LSH Linear Guide Rail LSH15BK-F1N-H-D-M4 the Right Guide?
Judge the part from every direction before you buy. Downsize: LRM shrinks the envelope for gentle duties but publishes no load ratings, so have us verify them first. Upsize: if the carried load overhangs, moment governs, and one step to LSH20 takes MR from 0.12 to 0.27 kN.m, roughly 125 percent more, which beats adding blocks for tipping problems. Across: LGC is worth comparing when the stroke is short and the application needs crossed-roller stiffness. Before ordering, tick off: this is a carriage alone with no rail, size 15 chosen on load and moment, F1 top flange, standard length, accuracy H, M4 lubrication point, and pairing code D identical to the letter on your rail.
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-H-D-M4 FAQ
Each carriage is rated 11.3 kN dynamic (C), 17.9 kN static (C0) and 0.12 kN.m static moment in MR, MP and My alike. Accuracy grade H gives a running parallelism band of 7-28 um. Rail mounting: M4 screws torqued to 412 N.cm (steel), 274 N.cm (cast iron), 206 N.cm (aluminium). Grease: 0.9 cm3 Mobilux EP2 initially, 0.3 cm3 per top-up, re-applied every 100 km of travel or every 3 to 6 months; after topping up, stroke the block at least three carriage-lengths twice and confirm an even film.
The rail is missing, deliberately; this SKU is carriage only. Pairing works by letter: LSH15 rails and carriages carry a pairing code, and a D carriage pairs with a D rail only. Read the letter off the old rail, usually stencilled near the end, or off the block you are replacing before ordering. If you also need a defined preload grade, that selection exists only on the complete-set code, not on this carriage-only shape.
