Airtac LRM Miniature Linear Guide LRM12L1X370S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X370S10AP 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 LRM12L1X370S10AP
This complete set pairs a 370 mm, 12 mm wide stainless-steel rail with one long recirculating-ball carriage, ordered as LRM12L1X370S10AP. The P in the code selects precision accuracy - the tighter running grade in the LRM range - while S10 sets the 10 mm end-hole offset and the absence of a trailing T means the rail is fixed from the top. The carriage arrives pre-filled with Kyodo Yushi PS No. 2 grease, so the set is ready to bolt down as received.
Precision grade is what separates this SKU from its H-accuracy sibling: on a ground or finish-milled seat, the tighter tolerances show up as straighter, more repeatable travel over the full 370 mm, which matters when a probe, camera or dispense tip must return to the same coordinates. The long carriage carries its rolling elements over a longer footprint, which resists any tendency of the moving table to tip. Balls are ISO 3290 G10 grade, Japanese-made, held captive by the retainer so the block can be handled without losing elements; the double-lip seal keeps grease in and dust out beneath an outer cover. Ambient temperature is limited to 80 C with transients to 100 C. AirTAC lists no load or moment rating for LRM - we confirm the numbers for this exact model before you order, so include it in your RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X370S10AP Is Used
Laser optical alignment carriage
A 370 mm slide carrying a mirror or sensor head on an optical bench, where precision grade P keeps the beam position repeatable over the whole stroke.
Semiconductor handler stage
Die and component handling stages inside compact semiconductor assembly equipment, where a 12 mm miniature rail fits a crowded chassis without redesign.
Coordinate measuring fixture
A light measurement fixture on a QC bench, built around one long carriage so the probe bracket stays level along its entire travel.
Is the Airtac LRM Miniature Linear Guide LRM12L1X370S10AP the Right Guide?
Rail length, not rail width, drives the price across this range - stocked sets span roughly $66 to $831 over just two widths, so trimming the 370 mm travel is the first lever on cost. Sizing-wise, LRM capacity is confirmed per model rather than tabulated; where you need published dynamic, static and moment ratings to calculate against, LSH is the step up for heavier or cantilevered duties, and LGC covers short travels that want crossed-roller rigidity. Order checklist: complete set, 12 mm rail, long carriage, one block, 370 mm length, preload A for freest motion, precision accuracy P, top-mount direction, and the per-model load rating confirmed with us before commitment.
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 LRM12L1X370S10AP FAQ
Rail width 12 mm, rail length 370 mm, one long carriage, preload grade A (none), accuracy grade P (precision), top-mount fixing with M3 screws torqued to 196 N.cm in steel, 127 N.cm in cast iron or 98 N.cm in aluminium. Ambient temperature limit is 80 C with transients to 100 C, and re-greasing with Kyodo Yushi PS No. 2 is due every 100 km of travel or every 3 to 6 months. Basic dynamic and static load ratings, moment ratings and running parallelism are not published for LRM - we confirm the load figure for this model on request.
You receive one matched set: a 370 mm stainless-steel rail, 12 mm wide, with a single long carriage factory-fitted and pre-greased. There is no second carriage, no rail joiner, no mounting screws and no black-chrome finish in this code - our stock is plain finish only, with black chrome available to order. The carriage carries a double-lip seal and outer cover, and the balls are captive in the retainer, but the manufacturer still warns that fitting or removing a block at an angle can drop balls, so keep it on the rail or work over a dummy rail if you must take it off.
