Airtac LRM Miniature Linear Guide LRM12L1X195S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X195S10AH 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 LRM12L1X195S10AH
LRM12L1X195S10AH is a complete miniature linear guide set from AirTAC: one 195 mm stainless-steel rail, 12 mm wide, with a single long (L) carriage pre-fitted, pre-greased and ready to bolt down from the top. The order code fixes the rest of the configuration - preload A, meaning the carriage runs with no applied preload, and accuracy grade H, the high grade.
The long carriage is the defining choice here: it spreads the load over a longer ball path and gives a wider bearing span, which steadies any tipping or overhanging detail on a small stage. Inside, recirculating balls to ISO 3290 G10 - a grade applied to the balls themselves, not the guide assembly - run between double-lip seals under an outer cover that shields the seal strip from larger debris. Ball retention keeps balls captive during handling, though the manufacturer warns that angling the carriage onto the rail can still drop them. Ambient temperature must stay at or below 80 C, with transient peaks to 100 C. Load and moment ratings are not published for LRM; we confirm the figures for your exact model when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X195S10AH Is Used
Desktop pick-and-place Z-head
Guiding the vertical motion of a small SMT prototype placer placing 0402 components, where the long carriage's wider bearing span steadies an off-centre vacuum gripper.
Compact vision inspection stage
Carrying the sample platen under a machine-vision camera checking solder joints on a 195 mm stroke, with grade H travel keeping the image path true.
Microplate drawer in a lab analyzer
Sliding the sample drawer of a benchtop biochemistry analyzer in and out on a 12 mm rail hidden under the deck, with grease top-ups possible through the rear lubrication hole.
Is the Airtac LRM Miniature Linear Guide LRM12L1X195S10AH the Right Guide?
Step up to AirTAC LSH when the load is substantial or hangs off a cantilever: LSH publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not - we can only confirm LRM figures per model. Step across to LGC when travel is short and the job needs crossed-roller rigidity. Before committing to this set, run the checklist: form (complete set), rail width 12 mm, long carriage, one block, 195 mm rail, preload A (easiest to install, freest running, least rigid), accuracy H, top-mount fixing - and confirm the load rating with us via RFQ.
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 LRM12L1X195S10AH FAQ
It is a complete set: 12 mm wide stainless rail, 195 mm long, one long carriage, preload A (none), high accuracy grade, top-mount rail fixing. Screw torque: M2 - 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 - 196, 127 and 98 N.cm respectively. Re-grease every 100 km of travel or every 3 to 6 months; keep ambient temperature at or below 80 C, peaks 100 C. Load and moment ratings are not published for LRM - we confirm them for this model when you send the RFQ.
Pick LRM when the envelope is tiny and the duty is light-precision positioning; pick LSH when the load is substantial or cantilevered, because LSH publishes per-carriage dynamic, static and moment ratings you can design against, while LRM's ratings are confirmed only per model with us. Availability also favours this choice: 924 of the 988 complete LRM sets we stock are size 12, so a 12 mm layout ships fastest.
