Airtac LRM Miniature Linear Guide LRM12N1X445S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X445S10CP 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 LRM12N1X445S10CP
LRM12N1X445S10CP pairs the tightest accuracy grade this series offers with a practical 445 mm stroke: one 12 mm wide stainless-steel rail, one standard-length ball carriage, fixed from the top through holes 10 mm from the rail ends. Grade P is the precision build, a step tighter in manufacture than the high grade H, which is the point of choosing this code for a measuring or optical axis.
The carriage is charged with Kyodo Yushi PS No. 2 grease at the factory and can be topped up through the hole at its rear; budget the re-grease by distance, not by calendar - a 200 mm stroke cycling once a second covers the 100 km interval in roughly three weeks of continuous running, so distance binds first. The balls inside are Japanese-made to ISO 3290 G10, the double-lip seal manages oil retention and dust, and an outer cover protects the seal strip. Note also that across the stocked range, price is driven by rail length rather than rail width, so a 445 mm set sits mid-span of the roughly $66 to $831 spread. Ambient temperature must stay at or below 80 C with peaks to 100 C. No load or moment rating is published for LRM; the figures for this exact model are confirmed per order - use the RFQ and we will provide them.

Where the Airtac LRM Miniature Linear Guide LRM12N1X445S10CP Is Used
Vision metrology stage
Carrying a camera over printed boards for automated optical inspection. Grade P accuracy supports repeatable positioning of the field of view, and the 445 mm rail covers full-panel scans.
Fibre alignment slide
Bringing a photonic component into line with a fibre collimator on an optical bench fixture. The precision grade and medium preload help the alignment hold while the coupling is adjusted.
Continuous-cycle test head
A life-test rig stroking a probe back and forth around the clock. Plan the re-grease by distance: at one cycle per second over a 200 mm stroke, the 100 km lubrication interval arrives in about three weeks.
Is the Airtac LRM Miniature Linear Guide LRM12N1X445S10CP the Right Guide?
When the duty involves real loads or an overhung mass, the honest step is AirTAC LSH, whose published per-carriage dynamic, static and moment ratings let you do the sizing sums yourself - LRM offers no published equivalents, so every LRM choice ends in a confirmation conversation with us. If the travel is short and crossed-roller rigidity is the priority, LGC is the alternative worth pricing.
Decide each item deliberately: complete set or carriage-only part; 12 mm rail width; standard or long carriage; carriage count; 445 mm rail length; preload C, the rigid choice that forgives alignment errors less; accuracy grade P, the tighter of the two; top-mount versus bottom-mount; and the pairing code when replacing a single carriage or rail. Finally, confirm load and moment ratings with us for this model before committing - that check is part of every LRM purchase we ship.
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 LRM12N1X445S10CP FAQ
A complete miniature guide: one 12 mm wide stainless-steel rail, 445 mm long, with a single standard-length carriage fitted, pre-filled with Kyodo Yushi PS No. 2 and fixed from above through holes 10 mm from each end. Preload is grade C (medium), accuracy is grade P (precision). Mounting screws are torqued at 196 N.cm into steel, 127 N.cm into cast iron or 98 N.cm into aluminium for M3, or 58.8, 39.2 and 29.4 N.cm for M2. Keep the surroundings at or below 80 C (brief peaks to 100 C) and re-grease 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 before you order.
Whenever the load stops being light or starts to cantilever. LSH publishes dynamic, static and moment ratings for every carriage, so you can size the guide from your own force data without waiting for a confirmation - LRM cannot offer that, and each model's capacity is verified individually before ordering. Conversely, if the stroke is short and you need the stiffness of crossed rollers, LGC is the better comparison. Send us the load, stroke and mounting sketch and we will tell you plainly which series fits.
