Airtac LRM Miniature Linear Guide LRM12N1X270S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X270S10AH 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 LRM12N1X270S10AH
LRM12N1X270S10AH is a complete AirTAC LRM miniature linear guide: one 12mm-wide stainless-steel rail, cut to 270mm, carrying a single standard-length recirculating-ball carriage. The rail is drilled for top mounting with the first hole set 10mm in from the end, and the carriage arrives assembled, pre-filled with Kyodo Yushi PS No. 2 grease and covered by the outer lid that hides its fixing screws.
AirTAC builds the LRM range around a common rail profile, so a long carriage from the same series can run on this rail if a later build needs a longer bearing span. Balls are Japanese-made ISO 3290 G10 grade - that grade applies to the balls alone, not to the assembly - held by a retention feature that stops them spilling during handling, although fitting at an angle or a hasty swap can still drop them. A double-lip seal scrapes grease and excludes dust. Keep ambient temperature at or below 80 C, peaking no higher than 100 C. Load and moment ratings are not published for LRM; ask us with an RFQ and we confirm the figures for this exact model.

Where the Airtac LRM Miniature Linear Guide LRM12N1X270S10AH Is Used
Benchtop vision inspection stage
An XY camera stage sweeping 270mm over populated PCBs fits this set: light moving mass, grade H straightness and a 12mm rail that disappears into a compact aluminium frame.
Autosampler X-axis in a lab analyser
A probe arm travelling from wash station to sample tray rides one standard carriage over 270mm; the pre-filled Kyodo Yushi PS No. 2 charge covers start-up, with re-greasing every 100km or 3 to 6 months.
Micro dispensing gantry
A fluid-dispensing head crossing a substrate tray gains from the double-lip seal, which keeps grease in and flux residue out of the raceway near the process zone.
Is the Airtac LRM Miniature Linear Guide LRM12N1X270S10AH the Right Guide?
Choose LRM for a tight envelope and smooth, light-duty travel; choose LSH when the load is substantial or cantilevered, because LSH publishes per-carriage dynamic, static and moment ratings you can size against - LRM publishes none. When travel is short and the priority is crossed-roller rigidity, LGC is the better cross-over. Checklist for this set: complete form with rail, 12mm rail width, standard carriage, one carriage, 270mm rail, preload A (none - lowest drag and simplest installation, but with running clearance), accuracy H, top-mount rail. Availability across the range is deepest at size 12, so this is a well-supported choice. Send the load case with your RFQ and we confirm the rating for this model before you commit.
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 LRM12N1X270S10AH FAQ
A matched complete set: one 12mm-wide stainless rail, 270mm long, drilled for top mounting with the first hole offset 10mm from the rail end, and one standard-length carriage already fitted and pre-filled with Kyodo Yushi PS No. 2 grease. There is no second carriage, no mounting screws and no spare rail sections in the box. Balls are ISO 3290 G10 grade and held by the retainer, but angle the carriage or swap it quickly and they can still drop - work slowly or use a dummy rail.
Published: 12mm rail width, 270mm rail length, standard carriage, one carriage per rail, preload A (none), accuracy grade H, top-mount rail. Assembly torque: M2 screws 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 screws 196, 127 and 98 N.cm respectively. Ambient temperature limit is 80 C with peaks to 100 C. Re-grease every 100km of travel or every 3 to 6 months.
