Airtac LRM Miniature Linear Guide LRM12N1X91S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X91S10AP 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 LRM12N1X91S10AP
LRM12N1X91S10AP is a complete AirTAC LRM miniature linear guide: a 12 mm wide stainless-steel rail, cut to 91 mm with end holes set 10 mm from each end, carrying one standard-length recirculating-ball carriage. The box holds the assembled pair, ready to fix down. This is a mechanical slide - nothing in it carries air - and it is built for light-duty precision positioning where a small envelope matters more than raw capacity.
The precision P grade is the headline here, and our stock reflects it: 924 of the 988 LRM sets we hold are size 12, so this configuration ships quickly. The carriage runs on Japanese-made balls graded ISO 3290 G10 - a ball-quality specification, not a standard for the guide itself - retained by the ball-retention design so they stay put during handling. A double-lip seal scrapes oil back and keeps dust out, while the outer cover shields the seal strip and hides the screw heads. Ambient temperature must stay at or below 80 C, peaking no higher than 100 C, so route the axis away from heaters and hot plates. One practical note: the 100 km re-grease interval arrives sooner than it sounds at short strokes, so plan greasing access now. AirTAC publishes no load or moment ratings for LRM; ask through the RFQ and we confirm the figures for this model.

Where the Airtac LRM Miniature Linear Guide LRM12N1X91S10AP Is Used
Lens inspection slide
On an electronics QC bench, a 91 mm rail carries a small camera holder under a microscope, and the precision P grade holds the image plane steady along the whole stroke.
PCB test fixture
Positions a pogo-pin probe plate across a row of test points on a compact in-circuit tester, where repeatable one-axis motion is the whole requirement.
Micro dispensing cell
Guides a miniature syringe dispenser across a short pass in a small glue-dotting cell, with the no-preload A grade keeping hand-set friction predictable.
Is the Airtac LRM Miniature Linear Guide LRM12N1X91S10AP the Right Guide?
If the load is substantial or overhangs the carriage, step up to AirTAC LSH: its catalogue publishes dynamic, static and moment ratings per carriage, which is the sizing maths LRM cannot support. Where the stroke is short and the job wants crossed-roller rigidity, LGC is the closer cross-series match. Work through the checklist before ordering: complete set or spare carriage, 12 mm rail width, standard or long block, one carriage on a 91 mm rail here, preload grade A (zero interference, so the freest running and the least rigid option), precision P accuracy, top-mount fixing, and the pairing code if you are replacing a block elsewhere. Send us the RFQ and we confirm the load rating for this exact model.
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 LRM12N1X91S10AP FAQ
Rail width 12 mm, rail length 91 mm, end holes 10 mm from the ends, one standard-length carriage, preload grade A (none), accuracy grade P (precision), top-mount fixing. Screw torque depends on the base: M2 screws take 58.8 N.cm in steel, 39.2 N.cm in cast iron and 29.4 N.cm in aluminium; M3 screws take 196, 127 and 98 N.cm respectively. Ambient temperature must stay at or below 80 C with peaks no higher than 100 C. Re-grease with Kyodo Yushi PS No. 2 every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them for this model when you send the RFQ.
Yes - LRM12N1X91S10AP is a complete set: the 91 mm stainless rail and the single standard carriage arrive assembled. Spare carriages are a different code shape (it contains BK and no X segment) and need a pairing letter that matches the rail; we hold only a handful of carriage-only items, so most spares are ordered to suit. If you want a spare block, tell us the full code engraved on your current set and we will quote it.
