Airtac LSH Linear Guide Rail LSH15BK-F2N-N-D-M4
The AirTAC Airtac LSH Linear Guide Rail LSH15BK-F2N-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-F2N-N-D-M4
The LSH15BK-F2N-N-D-M4 is one bottom-mount flange carriage from AirTAC's LSH range - block only, no rail, no preload choice, pairing code D, M4 grease fitting, normal accuracy. Inside, four rows of recirculating balls ride X-pattern 45 degree arc raceways at two points each, giving this size-15 carriage (matching rail width 15 mm) equal capacity in every direction and a degree of self-alignment on imperfect seats - within the catalogue allowances, not beyond them.
The figures that matter for a swap: 11.3 kN basic dynamic C, 17.9 kN basic static C0, and 0.12 kN.m for MR, MP and My alike. Note that static sits about 1.5 times above dynamic across this range - if you sized on C0 because it looks bigger, re-check against C, since C governs travel life. LSH carriages are interchangeable within the model: this block will run on any LSH15 rail carrying code D with its original smoothness preserved.

Where the Airtac LSH Linear Guide Rail LSH15BK-F2N-N-D-M4 Is Used
Bottling-line reject pusher
A reject pusher on a filler conveyor strokes a few hundred millimeters per bottle. Two of these blocks on one rail resist tipping along the travel while 11.3 kN of dynamic rating per carriage carries the push load.
High-cycle pick-and-place arm
Pick-and-place units cycling once a second cover 100 km of travel in roughly two weeks, so a spare normal-grade carriage kept on the shelf pays for itself in avoided downtime.
Granite comparator fixture rebuild
Measuring fixtures need predictable straightness: normal grade holds running parallelism to a 12-37 um band, and the interchangeable block drops onto any code-D LSH15 rail without re-matching.
Is the Airtac LSH Linear Guide Rail LSH15BK-F2N-N-D-M4 the Right Guide?
Size on both axes of the problem: load and moment. C of 11.3 kN and C0 of 17.9 kN cover the straight duty; 0.12 kN.m per direction covers tipping, and two blocks on one rail address tipping along the travel better than one bigger block. If the straight load is genuinely small and space is scarce, LRM may be enough - we confirm its unpublished ratings case by case. If travel is short and you want crossed-roller stiffness, look at LGC instead. Order against this list: carriage only (rail is a separate item), size 15, F2 bottom-flange mounting, standard length, normal accuracy, M4 nipple, pairing code D. When you order the mating rail, weigh preload too: medium preload on LSH15 cuts the allowable height error from 130 to 35 um, so rigidity costs installation latitude.
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-N-D-M4 FAQ
Catalogue ratings per carriage: C 11.3 kN, C0 17.9 kN, MR / MP / My each 0.12 kN.m. Normal grade running parallelism spans 12-37 um by rail length. Mounting screws for the 15 mm rail are M4 at 412 / 274 / 206 N.cm in steel, cast iron and aluminium. The carriage is supplied greased with Mobilux EP2 - 0.9 cm3 initially, 0.3 cm3 per top-up - re-applied every 100 km of travel or every 3 to 6 months.
It is a carriage only - the rail is a separate purchase and is not part of this code. Fit is by pairing letter: this block carries D, so it is matched to a code-D LSH15 rail. Within that match, AirTAC's interchangeability holds: any carriage of the model fits any rail of the model and keeps its smoothness and grade. For anything the catalogue does not state, such as base materials or weight, confirm from the datasheet or ask us with your RFQ.
