Airtac LRM Miniature Linear Guide LRM12N1X145S10APT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X145S10APT 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 LRM12N1X145S10APT
LRM12N1X145S10APT is a complete AirTAC LRM miniature linear guide: one stainless-steel rail, 12 mm wide and 145 mm long, carrying a single standard-length recirculating-ball carriage. The S10 segment fixes the end-hole offset at 10 mm, and the trailing T means the rail mounts from below, so screw heads sit under the rail and the surface above stays clear.
This exact configuration pairs a preload-free carriage (grade A) with precision accuracy (grade P) - a combination chosen when travel must feel free and track accurately rather than feel stiff. The carriage runs on ISO 3290 G10 balls (the grade applies to the balls only, not to the guide assembly), held by a ball-retention design, with a double-lip seal under an outer cover for oil retention and dust exclusion. Ambient temperature must stay at or below 80 C, with transient peaks no higher than 100 C. LRM load and moment ratings are not published in our catalogue source, so capacity for this exact model is confirmed per model before ordering - include it in your RFQ and we will return the figure.

| N | Standard carriage. |
| 1X145 | 1 carriage on a 145 mm rail. |

Where the Airtac LRM Miniature Linear Guide LRM12N1X145S10APT Is Used
Microscope stage slide
A precision-grade, preload-free guide glides a sample slide under the optics with minimal stick-slip, so the operator can sweep a slide smoothly across the field of view during inspection.
Compact XY stage axis
In a small bench-top positioning stage, a 12 mm bottom-mount rail bolts up from underneath the carriage plate, keeping the top surface flat and unobstructed for the mounted fixture.
Micro-dispensing head track
A light, free-running carriage carries a micro-dispensing needle over a PCB in short repeatable passes, where preload-free travel helps the head follow fine index positions without added friction.
Is the Airtac LRM Miniature Linear Guide LRM12N1X145S10APT the Right Guide?
If the load is substantial or cantilevered, step up to AirTAC LSH instead: that series publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not. If travel is short and the job demands crossed-roller rigidity, step across to LGC. Before committing to this set, confirm the full match: form (complete set), rail width 12 mm, standard carriage, one carriage, rail length 145 mm, preload A (installed play means the lowest running resistance but the least rigidity of the LRM grades), accuracy P, bottom-mount direction, and - critically - the load rating, which we confirm for the specific model before you order.
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 LRM12N1X145S10APT FAQ
Rail width 12 mm; rail length 145 mm; one standard-length carriage; end-hole offset 10 mm; preload grade A (none); accuracy grade P (precision); bottom-mount rail (trailing T). Installation torques: M2 screws 58.8 N.cm into steel, 39.2 N.cm into cast iron, 29.4 N.cm into aluminium; M3 screws 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium. Ambient temperature must not exceed 80 C, with peaks up to 100 C. Re-grease every 100 km of travel or every 3 to 6 months, whichever comes first. Load and moment ratings are not published for LRM; we confirm the figures for this specific model on request.
LRM is the smaller series and is selected for envelope, precision and smooth running in light-duty positioning. LSH is a larger series whose catalogue publishes dynamic, static and moment ratings per carriage, so if you need to run a sizing calculation against published numbers, LSH is the series to check. For the LRM12N1X145S10APT, we confirm the load capacity per model through the RFQ before you commit.
