Airtac LRM Miniature Linear Guide LRM12N1X80S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X80S10AH 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 LRM12N1X80S10AH
LRM12N1X80S10AH is a complete AirTAC LRM miniature linear guide: one 80 mm long, 12 mm wide stainless-steel rail with a single standard-length (N) recirculating-ball carriage already fitted. The S10 in the code places the first mounting holes 10 mm in from each end of the rail, so check your base-plate hole pattern against that before drilling. Everything needed for one axis is in the box - rail and carriage assembled, greased and ready to bolt down from above.
The carriage rolls on balls graded ISO 3290 G10 (a grade for the balls alone, not a standard for the assembly), held captive by a ball-retention design, with a double-lip seal for grease retention and dust exclusion plus an outer cover shielding the fixings and seal strip. Ambient temperature must stay at or below 80 C, with brief peaks to 100 C. Where a datasheet shopper expects a load rating, note that AirTAC publishes none for LRM - we confirm the figures for this exact model when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X80S10AH Is Used
Bench-top XY inspection stage
Two of these 80 mm rails set at right angles form a compact vision-checking stage; the low 12 mm profile leaves headroom for camera and lighting above.
Connector assembly micro-slide
Feeding and positioning a small connector or PCB fixture along a short stroke in an electronics assembly cell, where the miniature envelope beats a bulkier guide.
Optics lab lens carrier
Sliding a lens or filter holder across a lab bench; the sealed carriage and outer cover help keep grease and debris away from the optical path.
Is the Airtac LRM Miniature Linear Guide LRM12N1X80S10AH the Right Guide?
Size 12 is the heart of our LRM stock - 924 of the 988 sets we carry - so this short 80 mm rail sits at the fast, low-cost end of the range; and since price tracks rail length rather than width, trimming travel is the cheapest way to trim budget. If your load is substantial or cantilevered, step up to the LSH series instead: LSH publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not. For very short travel where crossed-roller rigidity matters more than stroke, LGC is the cross-over choice. Before ordering, tick the checklist: form (complete set), 12 mm rail width, standard carriage, one block, 80 mm rail, 10 mm end offset, preload A (free-running and most forgiving of mounting error), H accuracy, top-mount rail - and let us confirm the load rating for you.
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 LRM12N1X80S10AH FAQ
Rail width 12 mm, rail length 80 mm with a 10 mm end-hole offset, one standard-length carriage, preload A (none), accuracy H (high), top-mount rail. 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 in the same order. Ambient temperature limit is 80 C with brief 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.
It is a complete set: the 80 mm stainless rail arrives with the standard carriage mounted on it, factory-greased with Kyodo Yushi PS No. 2 and ready to install - nothing extra is needed for one axis. If you later want a spare carriage alone, our carriage-only shelf is very thin (four SKUs, all pairing code C), so a replacement is normally a special order. The ball-retainer design helps but does not guarantee against dropped balls if the carriage is fitted at an angle, so work slowly or use a dummy rail.
