Airtac LRM Miniature Linear Guide LRM12N2X470S10APT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X470S10APT 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 LRM12N2X470S10APT
LRM12N2X470S10APT is the bottom-mount version of this LRM12 set: a 470 mm stainless-steel rail, 12 mm wide, carrying two standard-length recirculating-ball carriages, built to precision accuracy grade P with preload code A (none). The trailing T in the ordering code changes the fixing direction - the rail is secured from underneath, which suits a base you cannot reach with a driver from above, or a deck where proud screw heads would foul anything crossing the carriage path.
The two carriages share LRM's common-rail geometry, so the same rail accepts either carriage length if a later rebuild needs it. Each carriage runs on Japanese ISO 3290 G10 balls - that grade describes the balls only - held by the ball-retention feature, though careful, straight-on fitting is still advised because an angled insertion can shed balls. Double-lip seals handle oil scraping and dust exclusion, and the outer cover keeps larger debris and the screw line covered. Ambient temperature must not exceed 80 C, with momentary peaks to 100 C. Two carriages spaced along 470 mm also resist tipping along the direction of travel better than a single block. Load and moment figures are not published for LRM; tell us the application via RFQ and we confirm the rating for this exact configuration.

Where the Airtac LRM Miniature Linear Guide LRM12N2X470S10APT Is Used
PCB bed-of-nails fixture
An in-circuit test fixture can hide its rail beneath the deck; bottom-mount fixing leaves the top surface clear for pogo pins and probe plates along the full 470 mm.
Fiber-alignment motion axis
A fiber or waveguide alignment axis needs precision-grade track over a long stroke; the 470 mm rail lets two carriages carry opposite ends of the alignment head.
Compact label-applicator head
A small labeler drives its applicator along the product stream; the 80 C ambient ceiling keeps the guide safe beside hot-fill lines and shrink tunnels.
Is the Airtac LRM Miniature Linear Guide LRM12N2X470S10APT the Right Guide?
For sizing, look one series up: LSH publishes per-carriage dynamic, static and moment ratings that you can drop straight into a load calculation, while LRM does not, so any heavy or overhung load belongs on LSH. If the stroke is short and crossed-roller rigidity is the goal, LGC is the cross-series alternative. Checklist for this SKU: complete set (rail plus two carriages), 12 mm rail width, standard carriage length, 470 mm rail, preload A, precision grade P, bottom-mount fixing, and no pairing code needed because the carriages ship matched to their rail. Availability is strong here - the large majority of stocked LRM sets are size 12 - but confirm the load rating with us for this exact model before you freeze the drawing.
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 LRM12N2X470S10APT FAQ
Yes: one stainless-steel rail 12 mm wide and 470 mm long, two standard-length carriages, 10 mm end-hole offset, preload code A (no preload), accuracy grade P, bottom-mount rail direction. Screw torques: M3 at 196 N.cm (steel), 127 N.cm (cast iron), 98 N.cm (aluminium); M2 at 58.8 / 39.2 / 29.4 N.cm for the same materials. Maximum ambient temperature 80 C with short peaks to 100 C. Factory grease is Kyodo Yushi PS No. 2, topped up every 100 km of travel or every 3 to 6 months. One thing the catalogue does not list is load and moment capacity for LRM - those are confirmed per model, so ask us before ordering.
Stay with LRM12 when the job is light-duty positioning in a tight envelope and you are choosing on size, smoothness and track accuracy. Move to LSH when you need to calculate: LSH publishes dynamic, static and moment ratings per carriage, which lets you verify the load case on paper. LRM publishes none of those, so its capacity is confirmed per model through us - if your application is cantilevered or carries real mass, LSH removes the guesswork.
