Airtac LRM Miniature Linear Guide LRM12N1X145S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X145S10AP 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 LRM12N1X145S10AP
LRM12N1X145S10AP is the precision-grade version of this miniature set: a 12 mm wide stainless-steel rail, 145 mm long, with one standard-length ball carriage, no preload (code A) and accuracy grade P - one step tighter than the H grade. Everything else matches the standard build: double-lip seal, outer cover over the screws, and a factory charge of Kyodo Yushi PS No. 2 grease.
The P grade earns its keep where travel accuracy is part of the product - gauging, inspection, optical positioning. One caveat to plan around: spliced (two-section) rails are offered in grade H only, so a P-grade set is a single-piece rail; at 145 mm that is no constraint, but it matters if the design later grows long. The recirculating balls are Japanese-made to ISO 3290 G10, a grade that applies to the balls alone rather than to the assembly. Ambient temperature must not exceed 80 C, with transient peaks to 100 C. Load and moment ratings are not published for the LRM series; send the RFQ and we will confirm the figures for this specific model.

Where the Airtac LRM Miniature Linear Guide LRM12N1X145S10AP Is Used
Gauge fixture slide
Positioning a dial-indicator stand along a gauge-checking fixture, where grade P travel accuracy keeps the reading trustworthy.
Optics alignment slider
Carrying a lens or mirror mount on a laboratory breadboard, with the stainless-steel rail wiping clean in a bench environment of fingerprints and reagents.
Probe positioning axis
Feathering a semiconductor test probe into position over a test board, where the light carriage moves smoothly by hand during setup and grade P holds the line.
Is the Airtac LRM Miniature Linear Guide LRM12N1X145S10AP the Right Guide?
Choose the P grade when the guide itself is part of the measurement chain - a measuring fixture, an optics mount, a scanning axis whose straightness feeds the result. If you cannot say how the load is carried, step to LSH: it publishes dynamic, static and moment ratings per carriage, giving you numbers to size with that LRM simply does not provide. Where travel is short and you need crossed-roller rigidity, LGC is worth comparing.
Before you commit: confirm the form (this is a complete set, not a bare carriage), rail width 12 mm, standard carriage length, one carriage, 145 mm rail, preload A (none - quickest to install, lowest inherent rigidity), accuracy P, top-mount rail, and confirm the load rating with us. Replacing a single carriage from an existing rail is a different item - carriage-only codes carry a pairing code and our carriage-only stock is limited.
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 LRM12N1X145S10AP FAQ
Rail width 12 mm, rail length 145 mm, one standard-length carriage, top-mount, preload A (none), accuracy P (precision). Fit with M2 screws at 58.8 N.cm into steel (39.2 cast iron, 29.4 aluminium) or M3 screws at 196, 127 and 98 N.cm. Ambient temperature limit 80 C, transient peaks to 100 C. Re-lubricate every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - they are confirmed per model, and we do that against your RFQ.
If the carriage carries a measuring instrument, yes - grade P tightens travel accuracy versus the H grade of the equivalent LRM12N1X145S10AH at the same size. Two limits to know: spliced multi-section rails come in grade H only, and accuracy grade does not change the load question - LRM publishes no load or moment ratings, so those must be confirmed with us per model. The box contains the 145 mm rail and one pre-greased carriage; no screws or accessories are included.
