Airtac LRM Miniature Linear Guide LRM12N2X470S10CPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X470S10CPT 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 LRM12N2X470S10CPT
This is the same 470 mm, 12 mm wide two-block LRM guide as its top-mount sibling, but the trailing T in the code changes how it fixes down: the rail is bolted from below, with screws inserted upwards, so the top face of the rail stays completely clear. That matters in enclosed frames, shallow channels or anywhere a tool cannot reach over the rail. The two carriages are standard length, the rail is stainless steel, and the end holes sit 10 mm in from each end.
Preload grade C on precision P rail gives this set a firm, low-play feel; the flip side is that the mounting surfaces must be ground or finish-milled and kept flat, because a stiffer preload forgives misalignment less. The ball-retention design holds the balls during normal handling, though inserting a carriage at an angle or swapping it hastily can still shed one - worth a dummy rail if you plan field swaps. Japanese-made ISO 3290 G10 grade balls ride the raceways, double-lip seals exclude dust, and the outer cover keeps larger debris off the seal strip. The ambient limit is 80 C with peaks to 100 C. Load and moment ratings are not published for LRM and are confirmed per model - send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X470S10CPT Is Used
Laser diode burn-in test bench
Bottom-mounting lets the rail sit flush inside an enclosed burn-in head with its top face clear, while preload C and precision grade P hold the diode fixture squarely through thousands of test cycles.
Flat-panel display edge inspection carriage
A camera carriage traversing the edge of a glass panel in an inspection frame, where the rail must bolt up from below into a shallow channel and two blocks keep the camera head from tipping.
Fibre connector polishing slide
A short-stroke polishing fixture for fibre connectors, where the 470 mm rail leaves room for several fixtures side by side and the double-lip seals keep polishing dust out of the raceways.
Is the Airtac LRM Miniature Linear Guide LRM12N2X470S10CPT the Right Guide?
When the load is heavy or hangs off an overhang, move to LSH - its catalogue lists dynamic, static and moment ratings per carriage you can check numbers against, which is exactly what LRM lacks, so capacity here is confirmed through us. For short travel where crossed-roller stiffness beats ball running, pick LGC. Before ordering, tick off: set form (rail included), 12 mm rail width, standard blocks, two per rail, 470 mm length, preload C, precision P grade, bottom-mount rail. Install with both carriages referencing the same datum side of the rail for the straightest running, and torque M3 screws to 196 N.cm in steel, 127 N.cm in cast iron, 98 N.cm in aluminium. One more commercial note: across stocked LRM sets the roughly 66 to 831 dollar spread comes almost entirely from rail length and block count, not width - trimming travel is the cheapest way to save.
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 LRM12N2X470S10CPT FAQ
A complete set: 12 mm wide stainless rail, 470 mm long, two standard-length carriages, medium preload C, precision accuracy P, bottom-mount rail, 10 mm S10 end offset. Screw torque for M3: 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium. Ambient temperature maximum 80 C with transient peaks to 100 C. Lubrication: the carriages ship filled with Kyodo Yushi PS No. 2; re-grease every 100 km of travel or every 3 to 6 months. Load, moment and running-parallelism ratings are not published for LRM - we confirm capacity for this model on request.
The set contains one 470 mm stainless rail, 12 mm wide, and two standard-length carriages pre-filled with grease; mounting screws are not included. The trailing T in the code means the rail is bolted from below through upward-facing holes, leaving the top face clear - useful inside enclosed housings or shallow channels where a tool cannot come down over the rail. Because the seat does the accuracy work, the surface should be ground or finish-milled. This is a mechanical guide, not a pneumatic part: no bore, no pressure, no air connection.
