Airtac LRM Miniature Linear Guide LRM12L1X470S10CHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X470S10CHT 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 LRM12L1X470S10CHT
LRM12L1X470S10CHT is a complete miniature linear guide, not a loose carriage: one stainless-steel rail 12 mm wide and 470 mm long, delivered with a single long recirculating-ball carriage already fitted and pre-greased. The long body spreads the load over more balls and lengthens the bearing span, which steadies any part of the load that wants to tip. Because the code ends in T, the rail is set up for bottom-mount fixing, so the screws are reached from below - the right answer for frames where you cannot get a tool above the rail.
AirTAC builds the carriage around Japanese-made balls graded ISO 3290 G10, a grade that belongs to the balls alone and not to the assembly, running in the common-rail profile shared by the LRM carriage range. A double-lip seal scrapes oil back and keeps dust out, while an outer cover shields the seal strip and hides the screw heads. Ambient temperature must stay at or below 80 C, with brief peaks no higher than 100 C, so keep the axis clear of heater housings and lamp heads. Load and moment ratings are not published for the LRM series; send the RFQ and we will confirm the figures for this exact part number before you order.

Where the Airtac LRM Miniature Linear Guide LRM12L1X470S10CHT Is Used
Desktop adhesive dispensing axis
The long carriage carries a small dispense valve along a 470 mm single axis above a PCB or gasket fixture, where a miniature guide keeps the head tracking straight without a bulky profile rail.
Laser diode alignment slide
On a benchtop photonics rig, the bottom-mount fixing lets the rail sit flush in a milled slot while an optics mount slides along to tune the beam path.
Adjustable stop on a PCB depaneling bench
Medium preload holds a position stop against cutting vibration on a compact router bench, and the operator can still re-set the stop by hand when the job changes.
Is the Airtac LRM Miniature Linear Guide LRM12L1X470S10CHT the Right Guide?
Size this part honestly. If the load is substantial or hangs off a cantilever, step up to AirTAC LSH: that larger series publishes per-carriage dynamic, static and moment ratings you can calculate against, which LRM does not. If the travel is short and the job needs crossed-roller rigidity rather than ball smoothness, LGC is the better match. Before ordering, run the checklist: complete set (yes here), 12 mm rail width, long carriage, one block, 470 mm rail, medium preload - firmer location but slightly more drag - accuracy grade H, bottom-mount fixing, and a 10 mm end-hole offset. Confirm the load and moment figures with us for this exact model as the final step. One practical pointer: our LRM coverage is deepest at size 12, and long carriages are listed as widely as standard ones, so this configuration is straightforward to source.
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 LRM12L1X470S10CHT FAQ
Published for this set: 12 mm rail width, 470 mm rail length, one long carriage, medium preload (C), high accuracy (H), bottom-mount fixing and a 10 mm end-hole offset. Screw torques are 58.8 N.cm into steel, 39.2 into cast iron and 29.4 into aluminium for M2 screws, and 196, 127 and 98 N.cm respectively for M3. Ambient temperature is limited to 80 C with transient peaks of 100 C, and re-greasing is due every 100 km of travel or every 3 to 6 months. Basic dynamic, static and moment load ratings are not published for the LRM series - we confirm the figures for this exact model when you enquire.
One 470 mm stainless-steel rail and one long carriage, mounted on the rail and pre-filled with Kyodo Yushi PS No. 2 grease. There is no second carriage, no mounting screws and no differently cut rail in the box. If you later want a spare carriage, note that our carriage-only LRM listing is very thin, so most spares are ordered to match - a carriage-only code carries a pairing letter from A to E that must match the rail, whereas this set code does not carry one, so order spares against the full set code or ask us.
