Airtac LRM Miniature Linear Guide LRM12N2X395S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X395S10AH 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 LRM12N2X395S10AH
The LRM12N2X395S10AH is a complete AirTAC LRM miniature linear guide set: one stainless-steel rail, 12 mm wide and 395 mm long, carrying two standard-length recirculating-ball carriages that arrive pre-fitted and pre-greased with Kyodo Yushi PS No. 2. The code has no trailing T, so this is a top-mount rail - it screws down from above through the fixing holes with a 10 mm end offset.
Two carriages on one rail resist tipping along the direction of travel better than a single block, which is why this count suits a head or plate that overhangs the rail. Inside each carriage the load is carried by Japanese-made ISO 3290 G10 balls - a grade applied to the balls themselves, not to the assembly - held by a ball-retention design that keeps them in place during routine handling. A double-lip seal scrapes oil and excludes dust, while the outer cover hides the screws and shields the seal strip from larger debris. 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 LRM; we confirm them for this exact model before you order, so send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X395S10AH Is Used
Benchtop microscope XY stage
A compact inspection stage under a benchtop metallurgical microscope, where a 12 mm rail keeps the deck low and two carriages keep the sample plate from rocking as it travels.
Connector-pin assembly pick and place
A small pick-and-place head setting pin connectors onto a PCB fixture; the second carriage on the 395 mm rail resists the tipping effect when the head reaches past the rail centerline.
Laser diode alignment slide
A fine-adjust slide for lining up a laser diode to a fiber pigtail in a production jig, where accuracy grade H and a smooth, grease-fed ball circuit give repeatable small moves.
Is the Airtac LRM Miniature Linear Guide LRM12N2X395S10AH the Right Guide?
If the load is more than light, or it is cantilevered off the carriage face, step up to AirTAC LSH: that series publishes per-carriage dynamic, static and moment ratings you can plug straight into a sizing calculation, which LRM does not. If the travel is short and the job needs stiffness more than reach, LGC crossed-roller guides are the stiffer cross-over choice.
Before ordering, tick through this list: complete set form (rail included), 12 mm rail width, standard carriage length, two carriages, 395 mm rail length, preload A (none - simplest to install, least rigid of the three grades under overturning), accuracy H, top-mount fixing, and a load and moment rating confirmed with us against your actual duty. If you plan a spare carriage later, note that only a handful of carriage-only SKUs are stocked and most replacements are a special order.
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 LRM12N2X395S10AH FAQ
This set uses a 12 mm wide rail, 395 mm long, with two standard-length carriages, preload A (none), accuracy H, and top-mount fixing with a 10 mm end-hole offset. Screw torque: M2 screws 58.8 N.cm into steel, 39.2 N.cm into cast iron, 29.4 N.cm into aluminium; M3 screws 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium. Ambient temperature must not exceed 80 C, with peaks no higher than 100 C. Re-grease every 100 km of travel or every 3 to 6 months. Basic dynamic, static and moment load ratings are not published for LRM, so we confirm the figures for this exact model - ask us via RFQ before committing.
A complete set: one 12 mm wide stainless-steel rail, 395 mm long, with two standard-length carriages already fitted and pre-filled with Kyodo Yushi PS No. 2 grease. There is no second rail, no spacers and no mounting hardware included. Before first use, wipe off the rust-preventive oil and apply lubricant. If you expected a spare carriage too, note that carriage-only parts are barely stocked - four SKUs at last count - so most spares are a special order.
