Airtac LRM Miniature Linear Guide LRM12N2X295S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X295S10CP 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 LRM12N2X295S10CP
The LRM12N2X295S10CP is a complete miniature guide set built around a 295 mm stainless-steel rail, 12 mm wide, running two standard carriages under medium preload (C). The P in the suffix marks precision grade, the tighter of the two accuracy classes offered on LRM, and the rail fixes from the top through its mounting holes. What arrives is the matched pair of carriages already seated on the rail, greased and sealed.
The recirculating balls inside each carriage are Japanese-made ISO 3290 G10 grade - that grade applies to the balls only, not to the accuracy of the guide as an assembly. LRM uses a common-rail profile, so other LRM carriages can share this same rail, though only within the LRM family. A double-lip seal manages oil scraping and dust exclusion, and an outer cover conceals the fixing screws while keeping larger particles off the seal strip. Keep the ambient temperature at or below 80 C, allowing brief peaks to 100 C. Because LRM publishes no load or moment ratings, the capacity of this exact configuration is confirmed per model - raise an RFQ with us before you commit.

Where the Airtac LRM Miniature Linear Guide LRM12N2X295S10CP Is Used
Vision inspection station
A camera carriage gliding above a tray of small moulded parts, where precision grade keeps the lens path repeatable from one inspection cycle to the next.
Fibre alignment bench
A photonics lab aligning a fibre array to a photonic chip with slow, fine corrective strokes that need low friction and a tight accuracy grade.
Small-parts measuring bench
A shop-floor comparator fixture measuring stamped contact pins, with P-grade travel supporting consistent probe positioning across shifts.
Is the Airtac LRM Miniature Linear Guide LRM12N2X295S10CP the Right Guide?
This is the configuration to shortlist when positioning repeatability is the priority and the load stays light. If your application involves a substantial or cantilevered mass, move up to AirTAC LSH instead: it publishes dynamic, static and moment ratings per carriage that you can plug straight into a sizing calculation, which LRM cannot offer. Where the travel is short and you need the rigidity of crossed rollers, LGC is the better cross-series choice. Tick through the checklist before ordering: form is a complete set, 12 mm rail width, standard carriage length, two carriages on one 295 mm rail, medium preload C (stiffer running, but it punishes imperfect mounting surfaces), precision accuracy P, top-mount fixing. And confirm the load rating with us - it appears in no table.
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 LRM12N2X295S10CP FAQ
Decide on ratings and envelope. LSH, the larger series, publishes basic dynamic load, static load and moment ratings per carriage, so you can size a real load against real numbers; LRM publishes none of these, and its role is miniature, light-duty positioning in a tight space. If the load is modest and compactness drives the design, this LRM12 set is the right tool and we confirm its capacity per model. If the load is heavy, offset or tipping, choose LSH. For short travels needing crossed-roller rigidity, look at LGC.
A 12 mm wide, 295 mm long stainless rail with two standard carriages, medium preload (code C), precision accuracy (code P), top-mount fixing, supplied complete and pre-greased. Mount on a ground or finish-milled surface to achieve the rated travel accuracy. M3 screws torque to 196 N.cm in steel, 127 N.cm in cast iron, 98 N.cm in aluminium. Ambient limit is 80 C with peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months - and note that a short-stroke stage cycling continuously can cover 100 km in weeks, so the distance limit usually binds before the calendar does. Load and moment ratings are not published for LRM; we confirm them per model.
