Airtac LRM Miniature Linear Guide LRM12N1X180S15AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X180S15AH 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 LRM12N1X180S15AH
This is a complete LRM12 miniature linear guide set from AirTAC: one 180 mm stainless-steel rail, 12 mm wide, carrying a single standard-length recirculating-ball carriage. The code ends in AH - preload grade A (none) and accuracy grade H (high) - and the S15 segment sets the end-hole offset at 15 mm, fixing the bolt-hole spacing relative to the rail ends. Rail and carriage arrive together as one matched unit, ready to bolt down from the top.
With no internal preload the carriage runs with the lightest breakaway of the three LRM grades, which suits axes that prioritise free, even travel over stiffness. The balls inside the carriage are ISO 3290 G10 grade, Japanese made, selected for roundness and wear; the double-lip seal scrapes oil and excludes dust while the outer cover keeps larger debris off the seal strip and hides the fixing screws. Ambient temperature must stay at or below 80 C, with transient peaks no higher than 100 C. Load and moment ratings are not published for the LRM series, so we confirm the figures for this exact part number when you send an RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X180S15AH Is Used
PCB vision inspection stage
A compact AOI camera stage built on a 12 mm rail: the 180 mm rail length gives useful travel in a small footprint, and preload-free running keeps the camera glide free of stick-slip.
Microplate pipetting head
A liquid-handling head moving between microplate positions needs smooth, repeatable short strokes; the high accuracy grade and the stainless rail suit a clean benchtop instrument.
Laser alignment fixture
Setting up a small lab laser calls for a slide that holds a line without play; with no preload the carriage moves easily by hand during alignment, and the top-mount rail fixes straight onto a drilled baseplate.
Is the Airtac LRM Miniature Linear Guide LRM12N1X180S15AH the Right Guide?
Size 12 is where this range genuinely lives: the overwhelming majority of stocked LRM sets are 12 mm wide, so a design laid out around this rail width is the easiest version of the family to source. Price across the range tracks rail length and carriage count far more than rail size, so if budget is tight, trim travel before you change size. If the load is substantial or cantilevered, step up to LSH instead - it publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not. Where travel is short and the job needs crossed-roller rigidity, look at LGC. Before ordering, match form (set or carriage), rail width, carriage length and count, rail length, preload and its installation trade-off, accuracy grade, mounting direction - and ask us to confirm the load rating for this exact code.
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 LRM12N1X180S15AH FAQ
It is a complete miniature guide set: 12 mm rail width, 180 mm rail length, one standard-length carriage, preload grade A (none), accuracy grade H (high), top-mount rail, 15 mm end-hole offset. M2 screws torque to 58.8 N.cm into steel, 39.2 N.cm into cast iron and 29.4 N.cm into aluminium; M3 screws to 196, 127 and 98 N.cm respectively. The ambient limit is 80 C with 100 C transient peaks, and re-greasing is due every 100 km of travel or every 3 to 6 months. Basic dynamic load, static load and moment ratings are not published for LRM; we confirm them for this model before you order.
The box contains the matched 180 mm rail and one standard carriage, pre-filled with Kyodo Yushi PS No. 2 grease. The ball-retention design keeps the balls in place during handling, but the manufacturer warns that inserting the carriage at an angle or swapping it hastily can still drop balls - plan on a dummy rail if you intend field carriage swaps. Do not dismantle the carriage, do not strike or drop the rail, and store the set flat, oiled and bagged away from heat and humidity.
