Airtac LRM Miniature Linear Guide LRM12N1X395S10AHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X395S10AHT 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 LRM12N1X395S10AHT
This LRM12N1X395S10AHT is a complete AirTAC LRM miniature linear guide set: one 395 mm stainless-steel rail, 12 mm wide, carrying a single standard-length recirculating-ball carriage, delivered as a matched assembly. The trailing T in the code means the rail is drilled for bottom mounting - the fixing screws pass up through the rail from underneath, so the top face stays clear while the carriage runs the full 395 mm of travel. No preload is fitted (grade A), so the carriage slides with the least rolling resistance this series offers, straight out of the box.
The carriage rolls on ISO 3290 G10 balls - the grade applies to the balls alone - held captive by the ball-retention design and wiped by a double-lip seal sitting under an outer cover that shields the seal strip and screw line. LRM carriages of the same size share one common rail profile. Ambient temperature must stay at or below 80 C, with brief peaks no higher than 100 C, so keep this rail away from heater blocks and oven panels. Where you would expect a load figure: LRM has none published, and we confirm the load and moment ratings for this exact model before you order - just send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X395S10AHT Is Used
Benchtop microscope XY stage
A compact inspection stage under a laboratory microscope: the 395 mm rail gives a long single axis in a 12 mm wide package, and bottom mounting keeps the working deck flush and unobstructed.
Automated vial handling tray
A sample shuttle inside a clinical analyzer, where the carriage moves a tray of vials past a sampling needle with light, steady, drag-free motion thanks to the zero-preload grade.
Small dosing head slide
A low-load dispensing slide on an electronics assembly bench, guided by a miniature rail that tucks inside a slim gantry profile where a full-size guide would never fit.
Is the Airtac LRM Miniature Linear Guide LRM12N1X395S10AHT the Right Guide?
Judge the family by the job. If the load is substantial or hangs on a cantilever, step up to AirTAC LSH: it publishes per-carriage dynamic, static and moment ratings you can plug straight into a calculation, which LRM does not offer. If travel is short and rigidity matters more than span, LGC crossed-roller guides are the stiffer choice. Before ordering, tick off: form (complete set), 12 mm rail width, standard carriage length, one carriage, 395 mm rail, preload A (none - easiest sliding, but any fitted clearance stays in the system), H high accuracy, bottom-mount drilling, and a load rating confirmed with us. Carriages alone are ordered as BK codes with a pairing letter, relevant only if you later need a spare.
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 LRM12N1X395S10AHT FAQ
It is a complete set: 12 mm wide stainless rail, 395 mm long, one standard-length carriage, no preload (A), H high accuracy, bottom-mount rail drilling. Screw torque is 58.8 N.cm into steel, 39.2 N.cm into cast iron and 29.4 N.cm into aluminium for M2 screws, and 196, 127 and 98 N.cm respectively for M3. Ambient temperature must not exceed 80 C, with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months with a compatible grease. Load and moment ratings are not published for LRM; we confirm them per model on request.
The box holds one rail and one carriage, factory-filled with Kyodo Yushi PS No. 2 grease and matched as a set. There is no second carriage, no mounting screws and no black-chrome finish - we stock plain finish only, though black chrome can be ordered. If you need a spare carriage it is bought as a separate BK code, and our carriage-only stock is very thin, so plan that purchase ahead.
