Airtac LRM Miniature Linear Guide LRM12N1X283S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X283S10AH 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 LRM12N1X283S10AH
The AirTAC LRM12N1X283S10AH is a complete miniature linear guide set: one 283 mm stainless-steel rail, 12 mm wide, with a single standard-length recirculating-ball carriage already fitted and greased. Nothing to assemble - bolt it down and it runs. The mounting holes sit 10 mm from each rail end.
This is the no-preload, high-accuracy (H) version. The rolling elements are ISO 3290 G10 grade balls - a specification for the balls alone, not a rating for the assembled guide - held captive by a ball-retention design so they stay put during handling, backed by a double-lip seal and an outer cover that shields the seal strip and screw line from debris. Ambient temperature must stay at or below 80 C. Load and moment ratings are not published for LRM; send the RFQ and we confirm the figures for this exact model before you order.

Where the Airtac LRM Miniature Linear Guide LRM12N1X283S10AH Is Used
Optical inspection XY stage
A compact benchtop XY stage for camera or sensor inspection, where the 12 mm rail keeps the stack low and the high-accuracy grade holds straight travel over the 283 mm span.
Electronics assembly pick-and-place
A small pick-and-place head slotting connectors onto PCBs; one carriage carries a lightweight gripper and the zero preload keeps motion effort low for a belt or lead-screw drive.
Laboratory measurement fixture
A metrology fixture carrying a probe or camera across sample trays, where the stainless rail copes with wipe-down routines and the H grade supports repeatable positioning.
Is the Airtac LRM Miniature Linear Guide LRM12N1X283S10AH the Right Guide?
If the load is substantial or hangs on a cantilever, step up to the LSH series instead - it publishes per-carriage dynamic, static and moment ratings you can actually size against, which LRM does not. If travel is short and you need crossed-roller rigidity, look across at LGC. Before ordering this set, check: form (complete set, not a spare carriage), 12 mm rail width, standard carriage length, one block, 283 mm rail, preload A (freest running and easiest to install, but the least rigid choice), accuracy H, top-mount fixing, and that the applied load and moment are confirmed 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 LRM12N1X283S10AH FAQ
It is a complete set: 12 mm wide stainless rail, 283 mm long, with one standard-length carriage, preload A (none), accuracy grade H (high) and top-mount rail holes. Fixing screws torque to 58.8 N.cm for M2 and 196 N.cm for M3 into steel, with lower values in cast iron and aluminium; mounting surfaces should be ground or finish-milled. Ambient temperature must not exceed 80 C, with momentary peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months. Basic load and moment ratings are not published for LRM - we confirm them for this model before you order.
It is the complete set - rail and carriage together, ready to bolt down. You do not need a separate carriage order or a pairing code; those apply only when buying a carriage on its own, of which we stock just a few. If you ever need a replacement carriage, read the pairing letter off your original rail first and order against it.
