Airtac LRM Miniature Linear Guide LRM12N1X195S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X195S10AP 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 LRM12N1X195S10AP
The LRM12N1X195S10AP is a complete miniature guide set: a 195 mm stainless steel rail, 12 mm across, with one factory-assembled standard-length carriage. The distinguishing choice is accuracy grade P - precision - which tightens the manufacturing tolerances of the rail and carriage above the high grade, at the cost of a smaller stock pool. Preload remains grade A, so travel stays free-running despite the tighter tolerances.
The precision edge matters only if the installation respects it: mount on a ground or finish-milled surface, and use either side of the rail as the datum face. ISO 3290 G10 Japanese balls run in the retained ball circuit; a double-lip seal manages lubrication and excludes fine dust, and the outer cover keeps larger particles off the seal strip. Re-greasing is due every 100 km of travel or every 3 to 6 months - on a 200 mm stroke cycling once per second, 100 km arrives in roughly three weeks of continuous running, so the distance binds long before the calendar does. Ambient limit is 80 C with peaks to 100 C. No load or moment ratings exist for LRM in published form; we confirm them for this model through an RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X195S10AP Is Used
Optical alignment stage
Positioning a lens or mirror in a benchtop instrument calls for the P grade: the tighter tolerances support repeatable returns to the same coordinate, while preload A keeps the adjustment feel light.
Semiconductor test socket indexer
Indexing small device packages under a probe card in an electronics assembly cell rewards precision-grade travel, and the standard carriage keeps the indexer footprint minimal.
Gauge fixture in a machining cell
A checking fixture beside a small CNC lathe faces mist and fine swarf; the double-lip seal together with the outer cover defends the ball circuit, though the 195 mm rail should sit away from hot chips and stay under the 80 C ambient ceiling.
Is the Airtac LRM Miniature Linear Guide LRM12N1X195S10AP the Right Guide?
Specify this P-grade set when positioning repeatability drives the machine spec and the load is light. If the load grows or the moment arm lengthens, LSH becomes the better engineering answer because its per-carriage dynamic, static and moment ratings are published and checkable; LRM has no published figures to size against. For short strokes needing crossed-roller rigidity, LGC is the cross-series alternative. Confirm before buying: this is a complete set (rail plus one carriage), rail width 12 mm, standard carriage length, one carriage, 195 mm rail, preload A, accuracy P, top-mount direction - plus a load rating confirmed with us.
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 LRM12N1X195S10AP FAQ
The P sets accuracy to precision grade, tightening rail and carriage tolerances above the H high grade - useful for repeatability in measuring and optical work. The box holds a 195 mm stainless steel rail, 12 mm wide, with one standard-length carriage factory-fitted and pre-greased with Kyodo Yushi PS No. 2; preload is A (none) and the rail mounts from the top. It is a mechanical guide, not a pneumatic component. Carriage and rail should not be separated. Black chrome finish is not part of this SKU, though it can be ordered in other variants.
Every 100 km of travel or every 3 to 6 months, whichever occurs first. The interval is shorter than it sounds: a 200 mm stroke cycling once a second covers 100 km in about three weeks of continuous running, so duty cycle - not the calendar - usually decides. Top up through the lubrication hole at the rear of the carriage: stroke it back and forth, inject from one side, then confirm an even film along the rail. Never mix lubricant types, and keep the ambient temperature at or below 80 C, with transient peaks no higher than 100 C.
