Airtac LRM Miniature Linear Guide LRM12N1X70S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X70S10CP 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 LRM12N1X70S10CP
Accuracy grade P is what sets LRM12N1X70S10CP apart: the same compact 12 mm miniature guide, built to the tighter of the two tolerance grades AirTAC offers on this series, on a 70 mm long stainless-steel rail with one standard recirculating-ball carriage, top-mounted. On a rail this short, the precision grade earns its keep where the carriage must come back to position consistently across repeated cycles.
The carriage runs on Japanese-made ISO 3290 G10 balls - the grade describes the balls alone, never the guide assembly - behind a double-lip seal with an outer cover over the seal strip. Preload is grade C, the firmest on offer, so the mounting face should be ground or finish-milled and the catalogue's per-size surface values checked first. Ambient temperature must remain at or below 80 C, with peaks to 100 C. Two practical notes: a short rail like this sits at the affordable end of the LRM price spread, which is driven by rail length and carriage count far more than by width, and AirTAC publishes no load or moment rating for LRM - we confirm the figures for this exact model via an RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X70S10CP Is Used
Optical-flat inspection slide
A metrology bench sliding small polished optics past an interferometer puts the P-grade rail millimetres from the measurement path, where fit and finish matter as much as travel.
Probe-card index stage
A wafer-level test rig steps a probe card between die sites on a compact 12 mm axis; the precision grade supports the fine, repeatable index pitch the test plan assumes.
High-cycle test-fixture shuttle
An electronics fixture shuttling boards between nest and probe block all day will cross the 100 km re-grease distance within weeks of continuous cycling, so plan lubrication access into the frame rather than trusting the calendar.
Is the Airtac LRM Miniature Linear Guide LRM12N1X70S10CP the Right Guide?
Precision grade P costs more than H, so spend it where the process measures or repeats; general light-duty positioning is usually served by grade H at lower cost. Whatever the grade, size the axis honestly: LSH publishes dynamic, static and moment ratings per carriage, the data you need once loads grow or hang off a cantilever, while LRM publishes none. LGC covers short-travel work where crossed-roller rigidity outranks envelope. For this SKU, confirm every line before ordering: complete set, 12 mm rail width, standard carriage, one block, 70 mm rail length, medium preload C and its tighter surface demands, P precision accuracy, top-mount fixing, plus the pairing code should a spare carriage ever be needed. Send the load details and we confirm the rating for this 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 LRM12N1X70S10CP FAQ
A 12 mm wide, 70 mm long stainless rail, one standard carriage, medium preload (C), precision accuracy (P) and top-mount rail fixing. M2 screws torque to 58.8 N.cm in steel, 39.2 N.cm in cast iron, 29.4 N.cm in aluminium; M3 to 196, 127 and 98 N.cm. Ambient temperature must stay at or below 80 C, peaks to 100 C, and lubrication is renewed every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them for this specific model on enquiry.
Against LSH the trade is data versus envelope: LSH publishes per-carriage dynamic, static and moment ratings for serious loads, while this LRM set offers a 12 mm rail and P-grade accuracy in a tight footprint with no published ratings, so we verify the load figure with you first. As supplied, the set is complete - rail and one standard carriage - but note that a short 70 mm rail leaves little travel beyond the carriage's own span, and carriage-only spares are mostly special orders matched by pairing code.
