Airtac LRM Miniature Linear Guide LRM12N1X245S10CHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X245S10CHT 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 LRM12N1X245S10CHT
The LRM12N1X245S10CHT is a complete miniature linear guide set: one stainless-steel rail, 245 mm long and 12 mm wide, with a single standard-length recirculating-ball carriage already fitted. Because the code ends in T, the rail mounts from below - you bolt through the rail into the machine base, so the fixing screws sit where they cannot be reached from above.
Three design points matter for this build. The ball-retainer design keeps the balls captive during handling, though the maker is clear that sliding the carriage on at an angle can still drop them. A double-lip seal scrapes oil back and excludes dust, and the outer cover shields the seal strip and hides the screws. The recirculating balls themselves are Japanese-made ISO 3290 G10 grade for roundness - a ball grade, not a standard for the guide. Ambient temperature must stay at or below 80 C, with short peaks to 100 C, so keep the rail clear of heater housings and hot plates. Load and moment ratings are not published for the LRM series; send the RFQ and we confirm the figures for your exact model before you order.

Where the Airtac LRM Miniature Linear Guide LRM12N1X245S10CHT Is Used
Microplate autosampler
A benchtop autosampler moving a pipetting head across a 96-well plate needs precise, light travel in a low profile. The bottom-mount rail bolts up under the deck, keeping the top surface flush for the plate carrier.
Laser alignment slide
Aligning a small laser diode module calls for fine, repeatable adjustments. Preload C stiffens the carriage against drift, and the 245 mm rail leaves room for coarse positioning before fine tuning.
Lens-handling pick-and-place head
A compact pick-and-place head moving lightweight lenses between trays suits the miniature format. The standard carriage keeps the guide short, and the double-lip seal excludes dust around the handling station.
Is the Airtac LRM Miniature Linear Guide LRM12N1X245S10CHT the Right Guide?
Size up before you commit. When the load is substantial or cantilevered, choose LSH instead - it publishes per-carriage dynamic, static and moment ratings you can check against your application, something LRM never states. Where travel is short and crossed-roller rigidity matters more than stroke, LGC is the better cross-series fit. For this SKU, confirm the form is a complete set, rail width 12 mm, standard carriage, count 1, rail length 245 mm, preload C (stiffer, but less tolerant of imperfect mounting), accuracy H and bottom-mount direction - then confirm the load rating with us before ordering.
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 LRM12N1X245S10CHT FAQ
Rail width 12 mm, rail length 245 mm, one standard-length carriage, preload C (medium), accuracy grade H, bottom-mount rail. M2 fixing screws torque to 58.8 N.cm in steel, 39.2 N.cm in cast iron and 29.4 N.cm in aluminium. Ambient temperature must stay at or below 80 C with peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months. AirTAC publishes no load or moment ratings for LRM - we confirm them per model before you order.
LRM is the miniature, light-duty end of the range: this set has a 12 mm rail and a single small carriage, chosen for compact size and smooth travel. LSH is the larger series and publishes basic dynamic load, static load and moment ratings per carriage, so if the load is substantial or cantilevered you can size it on paper there. LRM publishes no such figures, so with LRM we confirm the ratings for the specific model before you order. For short travel needing crossed-roller rigidity, compare LGC as well.
