Airtac LRM Miniature Linear Guide LRM12N1X230S15AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X230S15AH 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 LRM12N1X230S15AH
The LRM12N1X230S15AH is a complete set: a single 230 mm rail in 12 mm wide stainless steel with one standard recirculating-ball carriage running on it, mounted from above through the top of the rail. The S15 end-hole offset places the first mounting holes 15 mm in from the rail end, which shifts where your tapped holes must sit and can matter when butting the rail against a shoulder or clearing a fixed feature.
Preload code A means no preload, so the carriage glides with the least drag this series offers - a good match when you push the slide by hand or with a light actuator. The carriage holds ISO 3290 G10 Japanese balls in a recirculating circuit, with a double-lip seal for oil retention and dust exclusion and an outer cover shielding the seal strip and screw heads. Keep ambient temperature at or below 80 C, with short peaks to 100 C. LRM carries no published load rating; tell us the model and we confirm the figure with your RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X230S15AH Is Used
Laboratory autosampler deck
A multi-position autosampler slide in an analytical lab, where the unloaded carriage glides between vial positions with minimal push force.
Die-attach inspection fixture
A semiconductor die-attach inspection fixture where a light carriage carries a camera over wafers without disturbing placement.
Fibre alignment slide
A fibre-optic alignment slide adjusted by hand during bench testing, helped by the low-friction, preload-free fit.
Is the Airtac LRM Miniature Linear Guide LRM12N1X230S15AH the Right Guide?
With a 230 mm rail, one standard carriage and no preload, this set suits light, smooth-moving slides rather than stiffly located ones - if the job needs a rigid, preloaded guide, look at a C-preload LRM12 set instead. Where loads are substantial or cantilevered, LSH publishes the per-carriage dynamic, static and moment ratings needed to size properly, which LRM does not; for short travel needing crossed-roller rigidity, LGC is the alternative.
Check before you order: set form, 12 mm rail width, standard carriage, one block, 230 mm rail length, 15 mm end-hole offset, no preload, high accuracy grade, top-mount rail, and a load rating confirmed with us - plus the pairing code only if you are mixing carriages between rails.
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 LRM12N1X230S15AH FAQ
You receive one 12 mm wide, 230 mm long stainless-steel rail with one standard-length carriage on it - a complete set, mounted from above. Preload is A (none), accuracy is H (high), and the first end mounting holes sit 15 mm from the rail end. Torque the fixing screws to 58.8 N.cm (M2) or 196 N.cm (M3) into steel; lower values apply to cast iron and aluminium. Re-grease with Kyodo Yushi PS No. 2 every 100 km or every 3 to 6 months and keep ambient temperature under 80 C. Load and moment ratings are not published for LRM; we confirm them per model.
One complete set: the 230 mm stainless rail and one standard carriage, delivered pre-assembled with grease already inside. Nothing else is needed to mount it - though mounting screws are not supplied, so order M2 or M3 cap screws separately and match them to your tapped holes. Note that mounting surfaces must be ground or finish-milled for the rated travel accuracy, and either edge of the rail can serve as the datum face.
