Airtac LRM Miniature Linear Guide LRM12N2X470S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X470S10CP 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 LRM12N2X470S10CP
The LRM12N2X470S10CP is a complete AirTAC LRM miniature linear guide: one 12 mm wide stainless-steel rail cut to 470 mm, carrying two standard-length recirculating-ball carriages, fixed from the top through a 10 mm end-hole offset. In the box you get the rail with both carriages fitted; the surface beneath should be ground or finish-milled before assembly, because surface quality directly sets the travel accuracy you achieve.
This configuration pairs C medium preload - the firmest of LRM's three grades - with P precision accuracy, so the carriages track tightly along the full 470 mm at the cost of higher drag and stricter flatness demands on the mounting face. Every carriage runs on Japanese-made balls graded ISO 3290 G10, a grade that applies to the balls alone, held captive by the ball-retention design and sealed by a double-lip wiper beneath an outer cover that also hides the screw heads. Worth knowing before you lay the machine out: 12 mm is by far the most widely supported size in the LRM range, so designing around this rail keeps every future option open. AirTAC publishes no load or moment rating for LRM; send us the RFQ and we will confirm the figures for this exact model. Ambient temperature must stay at or below 80 C, with transients to 100 C.

Where the Airtac LRM Miniature Linear Guide LRM12N2X470S10CP Is Used
Wafer inspection microscope stage
Carrying a camera or probe head across a 470 mm scan on a semiconductor inspection bench, where P-grade tracking keeps the optical axis steady over the full traverse.
Laser optics alignment slide
Positioning a mirror or beam-splitter mount in a compact optical setup; the medium preload holds the carriage against drift without stiction spikes during fine adjustment.
Micro-dispensing gantry axis
A light-duty axis on a small adhesive or solder-paste dispenser, moving a needle over PCB pads where two carriages on one rail resist tipping along the travel.
Is the Airtac LRM Miniature Linear Guide LRM12N2X470S10CP the Right Guide?
Step up to LSH when the load is substantial or cantilevered: LSH publishes per-carriage dynamic, static and moment ratings you can size against, while LRM publishes none. Step across to LGC when travel is short and the job needs crossed-roller rigidity rather than ball recirculation. Checklist for this SKU: set form (not carriage only), 12 mm rail width, standard carriage length, two carriages, 470 mm rail, C medium preload (stiffest, least forgiving of misalignment), P precision accuracy, top-mount, 10 mm offset. Budget note: across LRM, price tracks rail length and carriage count far more than rail width, so trimming travel beats shrinking the rail when costs matter. Confirm load and moment ratings with us before ordering.
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 LRM12N2X470S10CP FAQ
It is a complete set on a 12 mm wide stainless rail, 470 mm long, with two standard-length carriages, C medium preload, P precision accuracy and top-mount fixing, 10 mm end-hole offset. Screw torque: M3 at 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium; M2 at 58.8, 39.2 and 29.4 N.cm respectively. Ambient temperature limit is 80 C with peaks to 100 C. Carriages arrive filled with Kyodo Yushi PS No. 2 grease; re-grease through the end port every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them per model on request.
Both are AirTAC linear guides, but they answer different questions. LRM, this series, wins on envelope: a 12 mm rail 470 mm long with two standard carriages is built for light-duty precision positioning in tight spaces. LSH wins on paper sizing: it publishes dynamic, static and moment ratings per carriage, which LRM does not, so any substantial or overhung load belongs on LSH. For short travels demanding crossed-roller rigidity, look at LGC instead. Send the RFQ with your load, moment and stroke and we will confirm the series and the ratings for your case.
