Airtac LRM Miniature Linear Guide LRM12N2X295S10BHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X295S10BHT 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 LRM12N2X295S10BHT
This LRM12N2X295S10BHT is a complete miniature linear guide set from AirTAC: one 12 mm wide stainless-steel rail, 295 mm long, carrying two standard-length recirculating-ball carriages. The trailing T in the code means the rail is bottom-mount, so the fixing screws pass up through the rail and thread into your machine from below - useful when the top face must stay clear or the screws sit in a pocket you cannot reach from above. The set arrives assembled, greased and ready to bolt down.
AirTAC builds LRM around a few deliberate choices. The common-rail profile lets any LRM12 carriage run on this rail, ball retention keeps the ISO 3290 G10 Japanese-made balls in place during handling, and a double-lip seal plus an outer cover shield the raceways from swarf and dust. Ambient temperature must stay at or below 80 C, with brief peaks to 100 C. Two carriages sharing one rail resist tipping along the travel far better than a single block; where a buyer would normally reach for a load figure, note that LRM ratings are confirmed per model - send us the RFQ and we will return the figure for this exact code.

Where the Airtac LRM Miniature Linear Guide LRM12N2X295S10BHT Is Used
Laser module alignment slide
A benchtop bar-code scanner build uses this set to translate a laser diode module past a focusing lens; the underside screws keep the optical axis unobstructed.
Micro dispensing gantry
A small glue-dispensing gantry for PCB conformal coating runs two carriages on a shared rail, and the light preload keeps the needle carriage gliding with minimal stick-slip.
Flatbed inspection camera
An under-mounted camera carriage in a flatbed inspection fixture travels the full 295 mm rail; mounting from below keeps the scanning window flush and free of screw heads.
Is the Airtac LRM Miniature Linear Guide LRM12N2X295S10BHT the Right Guide?
Size upward to LSH when the load is substantial or cantilevered: LSH publishes per-carriage dynamic, static and moment ratings you can calculate against, while LRM publishes none, so a heavy or overhung duty needs those tables. Step across to LGC when travel is short but the job demands crossed-roller rigidity. Before ordering, tick off the checklist: set form, 12 mm rail width, standard carriage length, two carriages on a 295 mm rail, preload B (light - easier sliding, a little less stiffness), accuracy H, bottom-mount direction, and confirm the load rating with us first.
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 LRM12N2X295S10BHT FAQ
This set has a 12 mm wide stainless rail, 295 mm long, with two standard-length carriages, light preload (B), high accuracy (H) and bottom-mount rail fixing. Screw torque: M2 screws take 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 take 196, 127 and 98 N.cm respectively. Ambient temperature must not exceed 80 C, with peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them per model before you order.
Yes - LRM12N2X295S10BHT arrives as one assembled rail-and-carriage set, greased with Kyodo Yushi PS No. 2. No separate pairing code applies, because the two carriages ship already fitted to the rail. Wipe off the rust-preventive oil and re-lubricate before first use, and remember the carriage can slide off an inclined rail under its own weight, so hold it during installation.
