Airtac LSH Linear Guide Rail LSH15F1N2X190S15CN-AM6
The AirTAC Airtac LSH Linear Guide Rail LSH15F1N2X190S15CN-AM6 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 LSH15F1N2X190S15CN-AM6
The LSH15F1N2X190S15CN-AM6 is a complete AirTAC LSH linear guide set: one hardened profile rail, 190 mm long, carrying two size 15 top-flange (F1) carriages of standard length, with the first bolt hole 15 mm from the rail end. The flange foot bolts down from the top, so the carriage mounting holes sit clear of the rail body. Four rows of recirculating balls run in X-shaped arc raceways at a 45 degree contact angle, two contact points per ball, which gives each carriage equal capacity for downward, liftoff and side loads and lets it absorb slight mounting-surface errors instead of binding. At size 15 the code matches the true rail width: 15 mm.
Medium preload (C) stiffens the ball circuit at a price worth knowing before you machine the base: allowable height error between rails drops from 130 um with no preload to 35 um at 500 mm spacing. Each carriage is rated 11.3 kN dynamic and 17.9 kN static with 0.12 kN.m in every moment direction, so a central load is shared by the pair. Sizing on the static figure alone undersells the guide - the dynamic rating governs travel life.

Where the Airtac LSH Linear Guide Rail LSH15F1N2X190S15CN-AM6 Is Used
Laser marking axis
Carrying the focus head of a fibre laser marker over 190 mm of travel for part serialisation, where medium preload keeps the head from rocking under acceleration.
Lab metrology slide
Driving the probe stage of a bench profilometer, where smooth, repeatable 190 mm traverse matters more than raw capacity.
Bench-top dispensing gantry
Guiding the syringe head of a glue-dotting unit across small PCB panels, with the flange foot bolted flat into a machined aluminium baseplate.
Is the Airtac LSH Linear Guide Rail LSH15F1N2X190S15CN-AM6 the Right Guide?
Size this guide by load and moment together, not load alone. For a 15 mm class duty with medium preload, this set suits axes that must resist vibration and run without play; if the duty is genuinely light and the envelope small, step down to AirTAC's LRM miniature series - its load ratings are not published in the same way, so we confirm them against your duty before quoting. If the moment governs, stepping up to LSH20 more than doubles the moment rating (0.12 to 0.27 kN.m), often cheaper than adding engineering margin elsewhere. Where travel is short and crossed-roller rigidity matters more than long recirculating travel, compare the LGC series. Before ordering, tick off: form (this is a complete set), size by load and moment, F1 top-flange carriage, standard length, two blocks, 190 mm rail, normal accuracy, medium preload with its tighter installation tolerance, and the AM6 fitting.
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 LSH15F1N2X190S15CN-AM6 FAQ
Each of the two carriages is rated 11.3 kN basic dynamic (C) and 17.9 kN basic static (C0), with 0.12 kN.m allowable static moment in each of the MR, MP and My directions. Running parallelism for the normal (N) accuracy grade is 12 to 37 um depending on rail length band. The rail takes M4 mounting screws torqued to 412 N.cm in steel, 274 in cast iron and 206 in aluminium. Each standard carriage ships charged with 0.9 cm3 of Mobilux EP2; top up 0.3 cm3 every 100 km of travel or every 3 to 6 months, whichever comes first.
Compared with a non-preloaded LSH15, the C grade cuts the allowable height error between two rails at 500 mm spacing from 130 um to 35 um, and parallelism error from 25 um to 13 um, scaled proportionally to your actual spacing. You gain a stiffer, zero-play guide; you pay with a flatter mounting datum and correct bolt torque - 412 N.cm per M4 screw in steel. If your base cannot hold that flatness, specify preload B or A instead.
