Airtac LRM Miniature Linear Guide LRM12N2X495S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X495S10AP is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriages. 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 LRM12N2X495S10AP
This SKU is a complete LRM miniature linear guide set: one stainless-steel rail, 12 mm wide and 495 mm long, carrying two standard-length recirculating-ball carriages with a 10 mm end-hole offset, fixed from above through top-mount holes. Everything arrives as one assembly, ready to bolt to a ground or finish-milled face. Two carriages on a single rail are the standard answer to a tipping load on a compact stage, because they resist tipping along the direction of travel.
AirTAC builds LRM around a common rail profile, so any LRM12 carriage shares this rail, and the ball-retention design keeps the balls captive while the carriage is handled. The balls themselves are ISO 3290 G10 grade, Japanese made, chosen for roundness and wear. A double-lip seal scrapes oil and excludes dust, and the outer cover shields the seal strip from larger debris. With accuracy grade P the running surfaces are finished to precision tolerances, and preload A gives the freest running in the range. Ambient temperature must stay at or below 80 C, with brief peaks to 100 C. Load and moment ratings are not published for LRM; we confirm the figures for your exact model before you order, so send us the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X495S10AP Is Used
Optical inspection bench slide
A 495 mm precision-grade rail carries a camera or sensor head along a bench-top measurement axis, where accuracy P and free-running preload A keep every image repeatable.
Laser alignment fixture
Aligning diodes and lenses on a small production line demands a slide that returns to position; two standard carriages on one rail steady a short-travel adjusting stage against tipping.
Semiconductor assembly micro-positioner
Fixture points on a 12 mm rail move wafer carriers and test probes between stations; the ball-retention design lets a technician lift a carriage for cleaning without losing balls.
Is the Airtac LRM Miniature Linear Guide LRM12N2X495S10AP the Right Guide?
Size the guide honestly before you commit. If the load is substantial or cantilevered, step up to AirTAC LSH: it publishes per-carriage dynamic, static and moment ratings you can calculate against, which LRM does not. If the travel is short and the job needs crossed-roller rigidity, LGC is the better match. For this set, confirm the form (complete set, two standard carriages), rail width 12 mm, rail length 495 mm, preload A and accuracy P against your drawing, and check that top-mount fixing suits your installation. Send the load details with your RFQ and we will confirm the rating for this exact model.
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 LRM12N2X495S10AP FAQ
It is a complete set: 12 mm wide stainless rail, 495 mm long, two standard-length carriages, 10 mm end-hole offset, preload A (none), accuracy P (precision) and top-mount fixing. M3 screws torque to 196 N.cm in steel, 127 N.cm in cast iron and 98 N.cm in aluminium. Ambient temperature must stay at or below 80 C, peaking briefly at 100 C. Re-grease every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM, so we confirm them per model before you order.
Choose LRM when the envelope is tight and the duty is light, as here, and step up to LSH when the load is heavy or overhung. LSH publishes dynamic, static and moment ratings per carriage that you can size against on paper; LRM has no published ratings, so we confirm them for your model. LRM12 is also the deepest stocked size in the range - 924 of 988 stocked sets - so this configuration ships faster than a 15 mm alternative.
