Airtac LSH Linear Guide Rail LSH15BK-F2N-P-D-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15BK-F2N-P-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-F2N-P-D-M4
LSH15BK-F2N-P-D is a precision-grade carriage from the LSH15 family, ordered without a rail: one F2 flange block of standard length, its mounting holes on the underside flange, fitted with an M4 grease nipple. The size 15 code corresponds to a 15 mm rail width. Four ball rows seated in opposed 45 degree arc grooves give the block the same load rating whichever direction the force comes from, and let it self-align over slight imperfections in the mounting face.
P grade is the tightest accuracy published for this range, with running parallelism between 3 and 21 um depending on rail length - a figure worth having when the block carries a measuring or optical element. Ratings per carriage: 11.3 kN dynamic, 17.9 kN static, 0.12 kN.m moment on each axis. One practical note: F2 bolts from below, and whether that joint is pulled square and torqued right has a large effect on the accuracy you actually achieve.

What Is In The Box
| This order | Carriage / block only |
|---|---|

This is a carriage on its own. NO RAIL IS INCLUDED. If you are not sure which form you need, send us the machine or the original part number and we will confirm it before you order.
Where the Airtac LSH Linear Guide Rail LSH15BK-F2N-P-D-M4 Is Used
CMM fixture slide refurbishment
Where a coordinate-measuring fixture slide has been crashed, the rail often survives and the block does not. Re-fitting this P-grade carriage restores 3-21 um running parallelism once the M4 screws are re-torqued to spec.
Syringe dosing station renewal
A lab dosing station that has developed stick-slip usually needs grease, or a block whose ball circuit has brinelled. This carriage ships pre-filled with Mobilux EP2 and takes a 0.3 cm3 top-up at each service.
Automated lens inspection cell
Production lens cells check focus by traversing a camera; the F2 body keeps carriage height low and the top face unobstructed. With MR, MP and My all at 0.12 kN.m, the direction of the moment load does not change the answer.
Is the Airtac LSH Linear Guide Rail LSH15BK-F2N-P-D-M4 the Right Guide?
Decide the form first: if you need a working guide from scratch, order a complete set instead - this code is the carriage alone. Where the moment on a cantilever limits the design, one size up pays: an LSH20 block lifts MR from 0.12 to 0.27 kN.m, more than doubling it for one part, while a second carriage on the same rail addresses tipping along the travel instead. Tiny envelopes with light duty can step down to LRM (ratings unpublished - we verify them case by case); short-travel stiff axes can cross to LGC.
Order checklist: carriage only, size 15 chosen on load and moment together, F2 bottom flange, standard length, P grade, M4 nipple, and pairing code D shared with the rail. Preload never appears on part codes - it is chosen when ordering a set, and no preload-D grade exists below size 25.
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-D-M4 FAQ
Dynamic rating C 11.3 kN; static C0 17.9 kN; MR, MP and My each 0.12 kN.m. P-grade running parallelism: 3-21 um across the rail-length bands. Fixing: M4 screws at 412/274/206 N.cm torque on steel/cast iron/aluminium. Lubrication: 0.9 cm3 first fill, 0.3 cm3 top-up, refreshed at 100 km travelled or every 3-6 months; the block arrives pre-filled with Mobilux EP2.
The box holds one F2 carriage, standard length, P accuracy - a rail is not included, so this code is not a complete guide. The pairing letter D must match the letter on your rail; take it from the old part's code. Preload does not appear on a carriage-only code: specify it on a complete LSH15 set, and note that the heaviest D grade simply does not exist at size 15 - it starts at size 25.
