Airtac LRM Miniature Linear Guide LRM12N1X370S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X370S10AP is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriage. It is the small end of the range, for light-duty precision positioning in a tight envelope — compact stages, small pick-and-place heads and inspection fixtures.

About the Airtac LRM Miniature Linear Guide LRM12N1X370S10AP
This code describes a precision-grade complete set: LRM12N1X370S10AP pairs a 370 mm stainless steel rail, 12 mm wide, with one standard-length recirculating-ball carriage, and the P in the code selects precision accuracy - the tighter of the two grades LRM offers. The rail mounts through its upper face, the conventional arrangement that suits most machine tables. The carriage arrives fitted and pre-filled with Kyodo Yushi PS No. 2 grease; before first use, wipe off the rust-preventive oil and run a fresh film of lubricant along the rail.
Precision grade earns its place in measuring and inspection machines, where the difference between H and P shows up as straighter, more repeatable travel. The recirculating balls are Japanese-made ISO 3290 G10 grade - a ball quality rating only, not a standard for the assembly - held captive by the ball-retention design so they stay put during routine handling. A double-lip seal manages oil scraping and dust exclusion, and an outer cover protects the seal strip while hiding the screw heads. Keep the ambient temperature at or below 80 C, peaks to 100 C. Note how these miniature guides are priced: within the LRM12 programme, cost climbs with rail length and carriage count far more than with the 12 mm width itself, so a 370 mm set like this sits far from a short cut of the same rail. Load and moment ratings are not published for LRM; send the RFQ and we will confirm the numbers for this model.

Where the Airtac LRM Miniature Linear Guide LRM12N1X370S10AP Is Used
Laboratory autosampler rail
Positioning a syringe or probe head over sample vials on a benchtop analyzer, where precision-grade travel keeps every pick repeatable.
Fiber-optic alignment fixture
Bringing a fiber collimator into line with a photonic component, where fine, straight adjustment is the whole point of the stage.
PCB inspection camera rail
Carrying an AOI camera module along a printed circuit board, with the rail bolted down to the machine deck from above.
Is the Airtac LRM Miniature Linear Guide LRM12N1X370S10AP the Right Guide?
If the load turns out to be substantial, or hangs off a cantilever, move up to AirTAC LSH - that series publishes dynamic, static and moment ratings per carriage, giving you hard numbers to size with, which is exactly what LRM lacks. For short travels where crossed-roller rigidity is the goal, choose AirTAC LGC instead. Order checklist for this SKU: complete set (rail and carriage together); 12 mm rail; standard carriage length; single carriage; 370 mm rail; 10 mm end offset; preload A (none) - the free-running choice that minimises drag and is the most forgiving of mounting-surface finish, with grades B and C offered when a tighter, stiffer feel is needed; precision accuracy P; top-mount; and a load rating confirmed with us against your actual payload before you commit.
Quick checklist
- ✓ Complete set, carriage only, or rail only?
- ✓ Load and moment confirmed with us
- ✓ 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 LRM Miniature Linear Guide LRM12N1X370S10AP FAQ
Published figures: 12 mm stainless steel rail, 370 mm long, top-mount; one standard-length carriage; preload A (none); precision accuracy grade P. Torques: 58.8 N.cm for M2 screws in steel (39.2 cast iron, 29.4 aluminium) and 196 N.cm for M3 in steel (127, 98). Ambient ceiling 80 C, brief peaks 100 C; re-grease every 100 km or 3 to 6 months. Dynamic load, static load and moment ratings are not published for the LRM series - confirm them with us for this model.
One complete, matched miniature guide: a single 370 mm stainless steel rail and one standard-length recirculating-ball carriage already running on it, pre-greased with Kyodo Yushi PS No. 2. There is no second carriage, no separate sealing strip to fit - the double-lip seal and outer cover are built into the carriage. If you want two carriages on one rail for tipping resistance along the travel, order the X2 version of the same code rather than trying to add a block later.
