Airtac LRM Miniature Linear Guide LRM12N1X170S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X170S10AP 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 LRM12N1X170S10AP
Where the catalogue offers a choice, the final letter decides the grade: LRM12N1X170S10AP is the precision (P) grade of the 170 mm, 12 mm wide size 12 set, with one standard carriage on a top-mount stainless rail, preload A and a 10 mm end offset. The carriage ships as part of the assembly, greased with Kyodo Yushi PS No. 2 and held on the rail by the ball-retention design.
Precision grade only pays off if the mounting surface cooperates - the catalogue asks for ground or finish-milled surfaces to achieve the rated travel accuracy, and quotes five height and edge-radius rows per size, so check your plate against them before machining. The recirculating balls are ISO 3290 G10 grade, Japanese made; the double-lip seal manages oil scraping and dust exclusion while the outer cover shields the seal strip from bigger debris. Keep ambient temperature at or under 80 C, with brief peaks to 100 C - a real constraint beside an oven door or a heated fixture. The manufacturer publishes no load or moment ratings for LRM, so we confirm the figures for your model through the RFQ before you order.

Where the Airtac LRM Miniature Linear Guide LRM12N1X170S10AP Is Used
Semiconductor test probing stage
A wafer-probing station's fine positioning stage moves a probe card across a short span, where precision-grade straightness protects contact repeatability.
Enclosed metrology cabinet slide
Inside a temperature-controlled measuring cabinet, a P-grade carriage carries a gauge head along a 170 mm window without disturbing the measurement stack.
Fiber connector polishing fixture
A polishing fixture for fiber-optic connectors sweeps the connector head in a controlled path; the miniature rail fits the tight tool envelope.
Is the Airtac LRM Miniature Linear Guide LRM12N1X170S10AP the Right Guide?
This is the right pick when straightness of travel matters more than force: complete set, 12 mm rail width, standard carriage, one carriage, 170 mm rail, preload A - the free-running, lowest-friction option; step to B or C when play must shrink, accepting a stiffer, less forgiving slide - plus accuracy P and top-mount installation. If the load is heavy or hangs on a cantilever, the honest answer is LSH: it publishes per-carriage dynamic, static and moment ratings you can calculate with, which LRM does not. Short travel needing crossed-roller rigidity points to LGC. Before ordering, work through the checklist and confirm the load rating with us for this exact model.
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 LRM12N1X170S10AP FAQ
Accuracy becomes the precision grade; the rest stays: 12 mm rail width, 170 mm rail, one standard carriage, preload A, top-mount, 10 mm end offset. Mount on a ground or finish-milled surface to realize the grade. Screw torque is 196 N.cm for M3 into steel, 127 N.cm into cast iron, 98 N.cm into aluminium; M2 takes 58.8, 39.2 and 29.4 N.cm. Ambient limit is 80 C with peaks to 100 C, and re-greasing is due every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them per model via the RFQ.
No - the accuracy grade describes travel precision, not capacity, and no load rating is published for LRM at either grade. If the duty involves real mass or an overhung moment, switch to the LSH series, which publishes dynamic, static and moment ratings per carriage for genuine sizing, while LGC covers short-travel jobs needing crossed-roller rigidity. Stay with this set when the machine is light and small, prepare the mounting surface properly, and confirm the load figure with us for the specific model before you commit.
