Airtac LRM Miniature Linear Guide LRM12N1X395S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X395S10AH 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 LRM12N1X395S10AH
LRM12N1X395S10AH is a single-carriage AirTAC LRM set: one 395 mm stainless-steel rail, 12 mm wide, with one standard-length recirculating-ball carriage in the plain finish. At 395 mm this rail uses a good slice of the 1005 mm maximum stocked length for size 12, giving a long, well-supported axis from a very small rail section.
Preload code A means the balls run with no interference fit at all, so drag is at its lowest and the carriage glides with the light breakaway force that manual stages and gravity-assisted slides want - the trade-off is a little more play under reversing loads. High accuracy (H) suits general precision machinery; the balls are ISO 3290 G10 Japanese balls tied to roundness and wear performance, sealed by a double-lip arrangement under an outer cover. Keep ambient temperature at or below 80 C, with transients no higher than 100 C. Because LRM carries no published load or moment ratings, the capacity of this set is confirmed per model before ordering - send the RFQ and we will confirm it.

Where the Airtac LRM Miniature Linear Guide LRM12N1X395S10AH Is Used
Manual optical trim stage
A hand-adjusted lens or mirror slide suits a preload-free carriage: the 395 mm axis moves with minimal finger force, and high accuracy keeps the beam repeatable.
Small parts escapement rail
Feeding small components along a guide under gravity or light spring force matches the low-drag, no-preload carriage on this long narrow rail.
Sample tray transport
Laboratory autosampler trays sliding to an analysis station run on long light-duty rails like this one, where smooth quiet travel matters more than stiffness.
Is the Airtac LRM Miniature Linear Guide LRM12N1X395S10AH the Right Guide?
Choose preload A when smooth, low-friction motion matters more than zero-play stiffness - for hand-fed fixtures, vertical slides held closed by gravity, or axes where slight clearance is harmless. This checklist matches the code: complete set, 12 mm rail width, standard carriage, single block, 395 mm rail, no preload, high accuracy, top-mount holes on a ground or finish-milled face. If the application pushes real load or a cantilever, go up to LSH, which publishes dynamic, static and moment ratings per carriage that you can size against - LRM's are confirmed per model only. Short-travel work needing crossed-roller rigidity belongs on LGC. Confirm the load rating with us before finalising the design either way.
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 LRM12N1X395S10AH FAQ
A 395 mm stainless-steel rail, 12 mm wide, with top-mount fixing holes, carrying one standard-length carriage. Preload: A, none. Accuracy: H, high. Fixing torque: M3 screws at 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium (M2: 58.8, 39.2 and 29.4 N.cm). Ambient temperature: 80 C maximum, brief peaks to 100 C. Grease: Kyodo Yushi PS No. 2 pre-filled, replenished every 100 km of travel or every 3 to 6 months. Load, moment and speed ratings are not published for LRM; we confirm them for this model on request.
It is a complete set - one rail with one carriage already fitted, ready to bolt down. Nothing else is needed for a single-axis slide, though you will want lubricant for the first top-up after wiping off the rust-preventive oil. Only four carriage-only SKUs exist in our stock, so if you later need a spare carriage for this rail it will normally be a special order; plan replacements accordingly, and use a dummy rail if you ever swap carriages in the field, since balls can still escape despite the retention design.
