Airtac LRM Miniature Linear Guide LRM12L2X355S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X355S10AH is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriages. 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 LRM12L2X355S10AH
LRM12L2X355S10AH is a complete AirTAC miniature linear guide: a 12 mm wide stainless rail, 355 mm long with a 10 mm end-hole offset, carrying two long recirculating-ball carriages, top-mounted, with no preload and the high H accuracy grade.
Preload A is the free-running choice. Because the balls carry no internal compression, the carriage slides with the least drag the series can offer, which suits mechanisms where a spring or the tooling own weight keeps the block seated; the flip side is that a reversing side load can show a small amount of play. The balls inside are ISO 3290 G10, Japanese made - a grade for the balls alone, not for the assembly - held captive by the ball-retention design, though a hurried or angled carriage fit can still shed one. A double-lip seal manages oil scraping and dust exclusion, and an outer cover keeps larger debris off the seal strip while hiding the screw line. Because LRM rails share a common profile, a like-for-like long carriage can later be matched to this same rail. Ambient temperature must stay at or below 80 C, worth checking before the guide is mounted near a lamp driver or heater. Load and moment ratings are not published for LRM; ask on the RFQ and we confirm them for this model.

Where the Airtac LRM Miniature Linear Guide LRM12L2X355S10AH Is Used
Indexing slide on a small parts sorter
A sorter that indexes light trays along a 355 mm bed cycles constantly; the free-running preload-A travel keeps drive effort low, and the re-grease schedule becomes the maintenance heartbeat.
Vision camera track on an electronics line
A line-scan camera riding a light rail over moving cable and connector assemblies holds position with the high H accuracy grade, without the drag a stiffer preload would add.
Laboratory dosing head axis
A dosing head that must glide to position under its own low force benefits from the minimal resistance of preload A, with the double-lip seal keeping the lubricant film even across the stroke.
Is the Airtac LRM Miniature Linear Guide LRM12L2X355S10AH the Right Guide?
When loads grow or hang off a lever arm, LSH is the step up, because its datasheet publishes the per-carriage dynamic, static and moment figures you can size from - figures LRM does not carry. When the travel is short and crossed-roller rigidity is the priority, compare LGC. Run the checklist before ordering: complete set, 12 mm rail width, long carriage, two blocks, 355 mm rail, A preload with no play removal but the lightest travel drag, H high accuracy, top-mount rail - and confirm the load rating with us against your actual duty.
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 LRM12L2X355S10AH FAQ
Rail width 12 mm; rail length 355 mm; two long carriages; preload A (none); accuracy H (high); top-mount rail; 10 mm end-hole offset. Fix into a ground or finish-milled surface - M3 screws take 196 N.cm in steel, 127 N.cm in cast iron, 98 N.cm in aluminium. The ambient temperature limit is 80 C, transient peaks 100 C, and the carriage is re-greased every 100 km of travel or every 3 to 6 months. Dynamic, static and moment load ratings are not published for LRM; we confirm them for this model on request.
Re-grease with Kyodo Yushi PS No. 2 through the rear lubrication hole every 100 km of travel or every 3 to 6 months, whichever comes first. The distance can bind sooner than it sounds: a 200 mm stroke cycling once per second covers 100 km in roughly three weeks of continuous running, so a fast-cycling machine services by the calendar only in name. Grease quantities vary per model - the catalogue quotes first charges from 0.02 to 1.0 cm3 - and never mix lubricant types.
