Airtac LRM Miniature Linear Guide LRM12L1X270S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X270S10AH 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 LRM12L1X270S10AH
The LRM12L1X270S10AH is a complete AirTAC miniature guide: one 270 mm stainless-steel rail of 12 mm width and one long recirculating-ball carriage, delivered assembled and pre-filled with Kyodo Yushi PS No. 2 grease. Preload A means none, so the carriage rolls with the least internal drag this series can offer - the choice for smooth, free-feeling travel, manual or motorized.
Size 12 is where this range lives: 924 of the 988 complete sets we stock are LRM12, so this configuration is among the quickest to ship and the easiest to extend. Across the range, rail length rather than rail width drives the price, so a 270 mm rail sits modestly above the shorter stocked lengths. The balls are Japanese-made to ISO 3290 G10, a grade for the balls themselves, and a double-lip seal holds the grease charge in place between top-ups. Keep ambient temperature at or below 80 C. One planning note: re-greasing every 100 km of travel comes around faster than it sounds, since a 200 mm stroke cycling once per second covers 100 km in roughly three weeks. Load and moment ratings are confirmed per model - ask us via RFQ before ordering.

Where the Airtac LRM Miniature Linear Guide LRM12L1X270S10AH Is Used
Microplate autosampler
With no preload, the carriage glides with minimal drag on short indexing moves, which suits the fast stop-start rhythm of a microplate sampler.
Sensor calibration bench
A 270 mm rail gives a longer calibration travel for positioning small proximity or temperature sensors against a reference target, with accuracy H for repeatable placement.
Small-parts sorting gate actuation
A light, non-preloaded guide moves a sorting gate by hand or with a small actuator, and the ball-retention design eases carriage handling during product changeovers.
Is the Airtac LRM Miniature Linear Guide LRM12L1X270S10AH the Right Guide?
Pick LRM for a tight envelope and light duty; pick LSH when you need published dynamic, static and moment ratings to size a heavier or cantilevered load against; pick LGC when travel is short and crossed-roller stiffness matters more than slimness. For this exact model, tick off: complete set, 12 mm rail width, long carriage, one carriage per rail, 270 mm rail length, preload A with zero internal drag but the most internal clearance, accuracy H, top-mount. We confirm the load rating per model - include it in your 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 LRM12L1X270S10AH FAQ
Rail width 12 mm; rail length 270 mm; one long (L) carriage; preload A, meaning none; accuracy H, high; top-mount rail with a 10 mm end-hole offset. Torque M3 screws to 196 N.cm into steel, 127 into cast iron, 98 into aluminium; M2 screws take 58.8, 39.2 and 29.4 N.cm in the same order. Ambient temperature limit is 80 C, transient peaks 100 C. Re-grease after every 100 km of travel or every 3 to 6 months. Load and moment ratings are deliberately absent from the LRM catalogue - we confirm them per model via RFQ.
Not from LRM - the series publishes no dynamic, static or moment ratings, and we will not guess at one. When even a light load needs documented figures, AirTAC LSH is the right tool: it is larger, but its catalogue lists per-carriage ratings you can size against, while LGC covers short travel where crossed-roller rigidity matters. For this LRM12 set, send the RFQ and we will confirm the capacity of the exact model you need.
