Airtac LRM Miniature Linear Guide LRM12N2X295S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X295S10AP 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 LRM12N2X295S10AP
The LRM12N2X295S10AP ships as a matched pair of precision-grade standard carriages running on a single 12 mm stainless-steel rail cut to 295 mm. Everything needed for one axis of light-duty travel arrives together - rail, two recirculating-ball blocks, seals fitted, top-mount screw holes on the upper face.
This code carries accuracy grade P, the tighter of the two LRM grades, which matters when two axes must track each other or when a measuring probe sits on the carriage. The balls rolling in the raceways are Japanese-made to ISO 3290 G10, and the carriage design adds a double-lip seal against dust plus an outer cover that protects the seal strip and hides the screws. Keep ambient temperature at or below 80 C. A practical note on budget: the stocked range spans roughly $66 to $831 across just two rail widths, so almost all of that spread comes from length and block count - the precision grade is a modest premium by comparison. Since no load or moment rating is published for LRM, ask us and we will confirm the figures for this exact configuration before you order.

Where the Airtac LRM Miniature Linear Guide LRM12N2X295S10AP Is Used
Electronics assembly gantry axis
A lightly loaded axis on a benchtop SMT machine, where two precision carriages keep a placement head square to the PCB over the full 295 mm travel.
Wire and ribbon feed slide
A light feed stage advancing fine wire or flat ribbon in a small electronics machine, where grade P holds line position stroke after stroke.
Rapid-optics carrier on an optical bench
A low-drag, unpreloaded twin-carriage slide ferrying a compact laser module across a bench, with top screws for fast layout changes.
Is the Airtac LRM Miniature Linear Guide LRM12N2X295S10AP the Right Guide?
Checklist for this SKU: complete set form, 12 mm rail width, standard carriage length, two carriages on one 295 mm rail, preload A (free-running, lowest drag), accuracy P, top-mount rail. Confirm the load rating with us before committing - LRM has none published. If the machine carries a cantilevered or substantial load, move up to LSH, whose catalogue states per-carriage dynamic, static and moment ratings you can plug straight into a calculation; LRM cannot support that on paper. For short-travel axes where crossed-roller stiffness matters more than long stroke, compare LGC. Availability is a genuine factor too: LRM12 is the best-stocked size in the range by a wide margin, so this precision-grade set ships faster than an equivalent in a non-stocked width.
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 LRM12N2X295S10AP FAQ
Rail width 12 mm; rail length 295 mm; two standard-length carriages; preload A, meaning no built-in clearance removal; accuracy grade P, the tighter LRM grade; top-mount rail. Screws follow the M2 torques of 58.8 N.cm (steel), 39.2 (cast iron) and 29.4 (aluminium), or M3 at 196, 127 and 98 N.cm. Keep the ambient at or below 80 C and re-grease every 100 km of travel or every 3 to 6 months. Basic dynamic load, static load and moment ratings are not published for LRM - send an RFQ and we confirm them for this model.
Everything for one axis is included: the 295 mm stainless-steel rail with both carriages factory-fitted. What is not included is a spare carriage - carriage-only replacements are thin on the ground (we stock only a handful of such SKUs), so if you plan field swaps, order a spare with the set. Note that even with the ball-retainer design, the manufacturer calls for careful, square insertion, ideally onto a dummy rail, to avoid dropping balls.
