Airtac LRM Miniature Linear Guide LRM12N2X395S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X395S10CP is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriages. 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 LRM12N2X395S10CP
The final letters of LRM12N2X395S10CP encode its character: preload C, the medium grade that removes running play for a tighter feel, and accuracy P, the precision grade of this series. The set itself is a 12 mm wide stainless-steel rail, 395 mm long, with two standard-length recirculating-ball carriages - a complete, ready-to-bolt axis for a light-duty precision positioner.
Accuracy P pays off only when the mating surface is good enough to hold it: grind or finish-mill the mounting pad, pick either long edge of the rail as the datum, and reference both carriages to that same side. Inside each carriage, Japanese-made ISO 3290 G10 balls run under a retention insert, a double-lip seal manages lubrication and dust, and an outer cover hides the screw heads while shielding the seal strip. Ambient temperature stays at or below 80 C with 100 C peaks allowed. Because LRM carries no published load or moment ratings, the figures for this model are confirmed case by case - include the model code in your RFQ and we will return them with the quote.

Where the Airtac LRM Miniature Linear Guide LRM12N2X395S10CP Is Used
Granite inspection slide
A small coordinate-checking fixture on a surface plate uses the P accuracy grade so the slide's running line stays true enough for comparative measurements.
Optical fiber alignment stage
Aligning a fiber to a photonic chip demands play-free, even motion; medium preload removes looseness while the miniature rail keeps the stage footprint tiny.
Precision jig and fixture build
Machine shops adding a hard-stop locating axis to a small fixture choose preload C so the position reads consistently, fixture after fixture.
Is the Airtac LRM Miniature Linear Guide LRM12N2X395S10CP the Right Guide?
An accuracy P guide rewards good engineering practice around it, but the load check still has to come from us: LSH publishes per-carriage dynamic, static and moment ratings you can size against, LRM does not, and LGC covers short travels where crossed-roller rigidity wins. Before committing, work through the list: complete set, 12 mm rail width, standard carriage, two blocks on one 395 mm rail, preload C (stiff, but higher running drag and less tolerance for imperfect pads), accuracy P, top-mount rail fixing, a confirmed per-model load rating via RFQ, and the pairing code question only if you later order a carriage-only spare - this set needs none.
Price note: across the stocked LRM12 range of about $66 to $831, rail width is nearly constant, so travel length and carriage count are what your budget actually reacts to.
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 LRM12N2X395S10CP FAQ
The figures you can rely on: 12 mm rail width, 395 mm rail length, two standard carriages, medium preload C, precision accuracy P, top-mount rail. Screw torques from the catalogue are 58.8 N.cm for M2 screws into steel and 196 N.cm for M3 screws into steel. Ambient limit is 80 C with 100 C transient peaks; re-grease every 100 km of travel or every 3 to 6 months, with grease quantities varying per model. Dynamic, static and moment load ratings are not published for LRM - we confirm them for this exact model on request.
If your design work needs arithmetic, LSH is the practical choice: its catalogue lists basic dynamic load, static load and moment ratings per carriage, none of which LRM publishes, so LRM sizing always ends with a confirmation from us. Stay with this set when the priority is a small 12 mm envelope, precision-grade running and smooth low-friction travel under light duty. When the travel is short and crossed-roller stiffness is the goal, look at LGC instead. Keep in mind that stocked LRM covers 12 and 15 mm widths only - 5, 7 and 9 are order-in items.
