Airtac LRM Miniature Linear Guide LRM12N1X184S17BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X184S17BP 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 LRM12N1X184S17BP
LRM12N1X184S17BP arrives as a factory-matched pair: a 184 mm rail in 12 mm wide stainless steel and one standard-length recirculating-ball carriage running on it, greased with Kyodo Yushi PS No. 2 and ready to mount.
Preload B is the light middle grade - some clearance taken up for steadier motion than the free-running A, yet friendlier to imperfect mounting surfaces than the rigid C. Accuracy is precision (P). If you cycle a 200 mm stroke once per second, note that the 100 km re-grease interval arrives in roughly three weeks of continuous running, so set a calendar reminder too; the carriage ships pre-filled, and topping up is done through the hole at its rear. Ball retention keeps the ISO 3290 G10 balls in place during handling, a double-lip seal scrapes oil and dust, and the ambient temperature limit is 80 C with 100 C peaks. Load and moment ratings are not published for LRM - we confirm them per model, so raise an RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X184S17BP Is Used
Vial sorting stage
A pharmaceutical vial sorting stage cycling near-continuously reaches the 100 km grease interval in about three weeks at a 200 mm stroke and one cycle per second, so top-ups are planned, not guessed.
Wafer transport micro-stage
On a wafer transport micro-stage, the precision P grade supports repeatable registration across the 184 mm rail while the top-mount screws sit beneath the stage plate.
Instrument service bench slide
A repair-bench slide for rebuilding miniature measuring instruments gives technicians the light B preload glide, and the stainless rail wipes clean during teardown work.
Is the Airtac LRM Miniature Linear Guide LRM12N1X184S17BP the Right Guide?
Price on LRM tracks length rather than width: our two stocked widths span roughly $66 to $831, and the spread is mostly rail length and carriage count, so trim travel before you trim size. Where the load is substantial or cantilevered, LSH is the better tool because its per-carriage dynamic, static and moment ratings are published - LRM's are not; short travel with crossed-roller rigidity points to LGC. Verify the match: complete set; 12 mm rail; a single standard-length carriage; 184 mm rail; preload B - light; precision P grade; top-mount. Confirm the load rating with us first.
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 LRM12N1X184S17BP FAQ
The rail is 12 mm wide and 184 mm long, carrying one standard carriage with a 17 mm end-hole offset; preload is B (light), accuracy is P (precision), and the rail mounts from the top. Torque figures: M2 screws - 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 screws - 196, 127 and 98 N.cm for the same three materials. Ambient limit: 80 C with peaks to 100 C. Re-grease every 100 km or every 3 to 6 months. Load and moment ratings are not published for LRM - confirm them with us per model.
It is a complete set: rail and carriage ship together, factory-assembled and pre-greased, so nothing else is needed to mount it. Replacing only the carriage would require a carriage-only code, of which we stock just four SKUs, so a swap is usually a special order - and the ball retainer, while helpful, does not stop balls dropping if the carriage is angled onto the rail.
