Airtac LRM Miniature Linear Guide LRM12N1X445S10AHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X445S10AHT 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 LRM12N1X445S10AHT
This listing is the bottom-mount variant of the AirTAC LRM12 set: a 445 mm stainless-steel rail, 12 mm wide, carrying one standard-length recirculating-ball carriage. The trailing T in the code means the rail is tapped for screws through the base, so you fix it from underneath - useful where the top face is a working surface or is out of reach once the machine is assembled.
Inside the carriage, Japanese-made ISO 3290 G10 balls circulate in raceways held by the ball-retention feature, and the double-lip seal plus outer cover keep grease in and debris out. Keep ambient heat at or below 80 C, with transients to 100 C. LRM lets either side of the rail serve as the datum face, and with more than one carriage on a rail the datum should sit on the same side for all of them - decide that before drilling. Load and moment capacities are not published for LRM; we confirm them per model when you request a quote.

Where the Airtac LRM Miniature Linear Guide LRM12N1X445S10AHT Is Used
Benchtop microscope focus axis
Fitting the rail from underneath keeps the top plate of a small microscope stage clear for slides and samples, while the double-lip seal excludes dust from the optics bay below.
Under-panel dispensing module
In a compact fluid-dispensing unit, base-fixing the 445 mm rail leaves the working surface uninterrupted for nozzles, sensors and guards mounted above it.
Recessed metrology fixture
Where a gauge fixture sits bolted into a machined recess, bottom-mount holes let the guide sit flush with no proud screw heads standing proud of the datum face.
Is the Airtac LRM Miniature Linear Guide LRM12N1X445S10AHT the Right Guide?
Bottom-mount fixing decided, work through the rest of the list: complete set with rail, 12 mm rail width, standard-length carriage, a single block, 445 mm of travel, preload A for the loosest, easiest-running fit, high accuracy grade.
On sizing: LSH is the step up when the payload is heavy or cantilevered, because LSH datasheets list dynamic, static and moment ratings per carriage while LRM publishes nothing to calculate with - we fill that gap by confirming figures for your case. For short strokes needing crossed-roller stiffness, look at LGC instead. Ask us to confirm the load rating for this exact set before you commit the design.
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 LRM12N1X445S10AHT FAQ
Rail width 12 mm, rail length 445 mm, one standard carriage, preload A (no preload), accuracy H, and bottom-mount fixing - the trailing T means the screws go through the base. Tighten M2 screws to 58.8 N.cm into steel (39.2 into cast iron, 29.4 into aluminium) and M3 to 196 N.cm (127, 98). Factory grease is Kyodo Yushi PS No. 2; top up every 100 km or every 3 to 6 months. Ambient air must stay below 80 C with peaks to 100 C. There is no published load or moment rating for LRM; we confirm it per model before you order.
The complete assembly: a 445 mm stainless-steel rail with the single standard carriage already fitted and pre-greased, plus tapped holes for base fixing. There are no separate end seals to add and no block to match - it is one matched unit. We stock LRM in sizes 12 and 15 only, so this 12 mm set is a stock item, while sizes 5, 7 and 9 are order-in. If you later need a spare carriage alone, only a handful of carriage-only SKUs are stocked and most are a special order; the rail's pairing code then matters.
