Airtac LRM Miniature Linear Guide LRM12L1X220S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X220S10AP 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 LRM12L1X220S10AP
This LRM12L1X220S10AP set contains a 220 mm stainless-steel rail, 12 mm wide, with one long carriage fitted in precision accuracy grade P. It is a single matched unit out of the box: recirculating-ball carriage on rail, seals in place, charged with Kyodo Yushi PS No. 2 grease.
Grade P is the tighter of the two LRM accuracy grades, which is why this code earns its place on small measuring and optical axes where running straightness is judged, not assumed. The rolling elements are Japanese balls graded ISO 3290 G10 - that grade describes the balls only, never the assembled guide. A double-lip seal and an outer cover protect the raceway, and the common LRM rail profile lets a standard carriage run on the same rail if you extend the axis later. Ambient temperature ceiling: 80 C, transient peaks 100 C. Load and moment ratings appear nowhere in the LRM catalogue, so put the model on an RFQ and we confirm the numbers before you commit.

Where the Airtac LRM Miniature Linear Guide LRM12L1X220S10AP Is Used
Connector measuring fixture
A shop-floor gauge that probes molded connector housings; precision grade P supports a repeatable probe approach on every cycle.
Die tray inspection indexer
An electronics inspection head stepping across a tray of packaged dies in short, precise increments over a 220 mm span.
Autofocus lens sweep
A machine-vision rig that translates its lens along one axis to hunt the sharpest focal plane, guided on a 12 mm miniature rail.
Is the Airtac LRM Miniature Linear Guide LRM12L1X220S10AP the Right Guide?
Size the axis honestly: if the load is heavy or overhung, step up to LSH, whose catalogue lists dynamic, static and moment ratings per carriage - numbers LRM simply does not publish. For short travels needing crossed-roller stiffness, LGC is the cross-series alternative.
Checklist for this code: it is a complete set with a 12 mm rail, a single long carriage on 220 mm of travel, no preload (A) for the freest-running feel, precision grade P, top-mounted. Size 12 is the heart of the LRM range carried here, so sourcing around this width is the well-trodden path. If you plan to match a spare carriage later, note the pairing code letter and that carriage-only purchases are usually special orders. Confirm the load rating with us before committing - the RFQ is the route.
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 LRM12L1X220S10AP FAQ
Rail width 12 mm, rail length 220 mm, one long carriage, preload A (none), precision accuracy P, top-mount rail. Mounting screws: M2 at 58.8 N.cm in steel, 39.2 in cast iron, 29.4 in aluminium; M3 at 196, 127 and 98 N.cm respectively. The ambient limit is 80 C with 100 C peaks, and re-greasing falls due every 100 km or every 3 to 6 months. Basic dynamic, static and moment load ratings are not published for LRM - ask us and we confirm them for this exact model.
Pick LRM for miniature, light-duty positioning in a tight space - this set gives you a 12 mm rail and a long carriage in precision grade P. Move to LSH when the load is heavy or cantilevered: LSH publishes dynamic, static and moment ratings per carriage, so you can size on paper, while LRM's ratings must be confirmed with us model by model. If the travel is short and you need crossed-roller rigidity, LGC is the other option.
