Airtac LRM Miniature Linear Guide LRM12N2X995S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X995S10AH is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriages. 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 LRM12N2X995S10AH
This AirTAC LRM12N2X995S10AH is a complete miniature linear guide set: one stainless-steel rail, 12 mm wide and 995 mm long, carrying two standard-length recirculating-ball carriages. The rail fixes from the top, the accuracy grade is H (high), and the preload code A means the carriages run with no built-in preload, so what you receive is ready to bolt down and move.
AirTAC builds the LRM range on a common-rail profile, so a carriage from elsewhere in the series shares this rail geometry. The balls inside each carriage are Japanese-made to ISO 3290 G10 grade - a grade covering the balls alone - while a double-lip seal scrapes oil back and excludes dust, and an outer cover hides the screw heads and shields the seal strip from larger debris. Ambient temperature must stay at or below 80 C, with transient peaks no higher than 100 C. At 995 mm this is the longest stocked rail length we carry, just 10 mm short of the 1005 mm catalogue full length for size 12, so there is almost no room left to extend travel on a single rail. Load and moment ratings are not published for the LRM series; we confirm the figures for this exact model before you order - send the RFQ and we will come back with them.

Where the Airtac LRM Miniature Linear Guide LRM12N2X995S10AH Is Used
Long-stroke vision inspection stage
A camera bridge that traverses the length of a populated PCB in electronics inspection can ride on a single 995 mm rail with two carriages, keeping the optical path steady across nearly a metre of stroke.
Laboratory dispensing gantry
A liquid-handling workstation sliding reagent heads along a full-metre axis can use this near-full-length size 12 guide where the layout allows one straight rail instead of a spliced pair.
Small-parts laser marking line
A compact fibre-laser station marking serial numbers on connectors can run its Y-axis on this two-carriage set; two blocks on one rail resist tipping along the direction of travel.
Is the Airtac LRM Miniature Linear Guide LRM12N2X995S10AH the Right Guide?
Size upward to the AirTAC LSH series when the load is substantial or hangs on a cantilever: LSH publishes per-carriage dynamic, static and moment ratings you can put into a calculation, which LRM does not. Step across to LGC when the travel is short but the job demands crossed-roller rigidity. Match this SKU against your drawing line by line: complete set with rail included, 12 mm rail width, standard carriage length, two carriages, 995 mm rail, preload A (the easiest grade to install, with the freest play under overturning), accuracy H and top-mount fixing. Before committing, confirm the load rating with us for this specific 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 LRM12N2X995S10AH FAQ
It is a complete set: 12 mm rail width, 995 mm rail length, two standard-length carriages, preload A (none), accuracy H (high) and top-mount rail fixing. Fastening torque for M3 screws is 196 N.cm into steel, 127 N.cm into cast iron and 98 N.cm into aluminium; for M2 screws, 58.8, 39.2 and 29.4 N.cm respectively. Ambient temperature must not exceed 80 C with peaks to 100 C, and the carriages should be re-greased every 100 km of travel or every 3 to 6 months. Dynamic, static and moment load ratings are not published for LRM - we confirm them for this model on request.
Pick LRM for a light-duty miniature axis where envelope size, smoothness and finish quality matter most. If the load is heavy or overhangs the carriage, LSH is the better tool because its catalogue lists per-carriage dynamic, static and moment ratings you can size against; LRM publishes none, so each application is checked by hand. If travel is short and stiffness is the priority, LGC with crossed rollers is also worth comparing. Send us the mass, centres of gravity and duty cycle, and we will confirm the right series and the load rating for this model.
