Airtac LRM Miniature Linear Guide LRM12N1X320S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X320S10CP 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 LRM12N1X320S10CP
One box, one assembled guide: LRM12N1X320S10CP pairs a 320 mm stainless-steel rail, 12 mm wide, with a single standard-length carriage, shipped together and pre-lubricated with Kyodo Yushi PS No. 2 grease. The absence of a trailing T means top-mount - the rail bolts down from above, which makes alignment against a ground or finish-milled shoulder straightforward during first assembly.
This is the rigid-and-precise combination: preload C for a clearance-free carriage and accuracy grade P for the tightest running tolerance LRM offers, a sensible pairing for fixtures where a probe or optic must repeat its position. Japanese-made ISO 3290 G10 balls run inside, held by the retention design; still, slide the carriage on square and avoid quick removals, or balls can drop. The double-lip seal scrapes oil and blocks dust while an outer cover shields the seal strip from larger debris. Keep ambient temperature at 80 C or below. LRM publishes no load or moment rating, so we confirm the figure for this exact configuration when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X320S10CP Is Used
Pipetting workstation rail
A laboratory pipetting head rides this precision-grade rail across microplate rows, where clearance-free travel keeps tip alignment consistent plate after plate.
Fiber-optic coupling stage
Aligning a fiber to a laser diode demands repeatable positioning; accuracy grade P and preload C hold the coupling stage still between adjustments.
Carton code-reader slide
On a packaging line, a compact barcode scanner travels a 320 mm rail across carton faces; top-mount fixing makes rail removal and refitting a quick bench job.
Is the Airtac LRM Miniature Linear Guide LRM12N1X320S10CP the Right Guide?
Rail length and carriage count, not rail width, account for most of the price spread in this family, so trimming travel before upsizing is the economical route - and 12 mm is the size the range runs deepest on, so a design laid out around this rail width is the straightforward one to source. If the load is substantial or cantilevered, size it against AirTAC LSH instead, which publishes per-carriage dynamic, static and moment ratings; if the stroke is short and crossed-roller rigidity is the goal, LGC is the better match. Order checklist: complete set (not carriage only), 12 mm rail width, standard carriage, one carriage, 320 mm rail, preload C, accuracy P, top-mount. Confirm the load rating with us for this model before you commit.
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 LRM12N1X320S10CP FAQ
The published ones: 12 mm rail width, 320 mm rail length, one standard-length carriage, medium preload C, precision accuracy P and top-mount rail fixing. Screw torques: M2 - 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 - 196, 127 and 98 N.cm. Regrease every 100 km of travel or every 3 to 6 months through the hole at the carriage rear; ambient temperature must not exceed 80 C. What is not published is load: LRM carries no dynamic, static or moment rating, so we confirm the numbers for this exact model on request.
The top-mount rail (no trailing T) lets you set and align the rail from above against a ground or finish-milled shoulder, which speeds first assembly and any later removal. The bottom-mount variant buries the screws under the rail for a clean top surface, at the cost of access. Both share the same 12 mm rail profile, 320 mm length, single standard carriage, preload C and grade P accuracy. For the load rating, which applies to either direction, send the RFQ and we confirm it per model.
