Airtac LRM Miniature Linear Guide LRM12N1X70S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X70S10AP 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 LRM12N1X70S10AP
LRM12N1X70S10AP is a complete AirTAC LRM set built around accuracy: a 12 mm wide stainless-steel rail, 70 mm long with mounting holes offset 10 mm from the ends, and one standard-length recirculating-ball carriage specified to P (precision) grade rather than the standard high grade. The carriage is fitted and pre-greased at the factory.
The balls inside the carriage are Japanese-made to ISO 3290 G10 - a ball grade only, not a standard for the assembly - and sit behind a double-lip seal with an outer cover protecting the seal strip and hiding the screws. Choosing P grade tightens the travel accuracy of the unit, which is why it earns its place on measuring and inspection hardware, and with no preload (grade A) the running feel stays free and easy. Keep the ambient at or under 80 C, with transient peaks to 100 C. LRM has no published load or moment ratings, so the figures for this exact model are confirmed by us on request.

| N | Standard carriage. |
| 1X70 | 1 carriage on a 70 mm rail. |
| S… | End-hole offset from the rail end, in mm. |
| A | A — no preload — higher preload raises rigidity and tightens how flat the mounting surface must be. |

Where the Airtac LRM Miniature Linear Guide LRM12N1X70S10AP Is Used
Optical inspection micro-stage
A small stage that presents machined parts under a stereo microscope camera; P-grade travel keeps image drift across the 70 mm stroke low enough for visual comparison work.
Lens centring fixture
Aligning small optics in a barrel before bonding, where the precision grade and the un-preloaded, free-running carriage let an operator feel the centring without stick-slip.
Wafer-piece inspection bench
Moving a wafer fragment past a microscope objective in an electronics lab; the stainless rail and double-lip sealed carriage wipe clean easily on a clean bench.
Is the Airtac LRM Miniature Linear Guide LRM12N1X70S10AP the Right Guide?
When your drawing calls out a precision-grade miniature guide for a measurement axis, this is the LRM code that answers it: 12 mm rail width, 70 mm length, standard carriage, preload A, accuracy P, top mounting. If the applied load is significant or the carriage carries a cantilever, step up to LSH instead - it publishes the per-carriage dynamic, static and moment ratings that LRM deliberately omits, turning sizing into a calculation rather than a confirmation. For short strokes that need crossed-roller stiffness, compare LGC. Your checklist: complete-set form, rail width and length, carriage length and count, preload (A keeps installation forgiving; B or C trade smoothness for rigidity), accuracy grade, mounting direction, and the load rating confirmed with us before the order is placed.
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 LRM12N1X70S10AP FAQ
In numbers: 12 mm stainless rail, 70 mm long, top-mount with end holes offset 10 mm; one standard (N) carriage; preload A (none); accuracy P (precision). M3 screws at 196 N.cm into steel, 127 N.cm into cast iron and 98 N.cm into aluminium. Ambient: 80 C maximum, 100 C transient peak. Grease: Kyodo Yushi PS No. 2 fitted; refresh every 100 km of travel or every 3 to 6 months, whichever comes first. Load, moment and running-parallelism values are not published for LRM; we confirm the datasheet figures for this model when you ask.
One assembly: the 70 mm rail with its carriage already fitted and pre-greased, so nothing needs assembling on the bench. Avoid pulling the carriage off the rail unless you must - dismantling or hasty removal risks lost balls and raceway damage that no visible inspection will reveal. If you need a bare spare carriage, note that carriage-only LRM items are held only in small numbers, so a replacement is normally ordered to match; in that format rails and carriages are matched by a pairing code.
