Airtac LRM Miniature Linear Guide LRM12L1X105S15AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X105S15AH 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 LRM12L1X105S15AH
LRM12L1X105S15AH is a complete AirTAC LRM miniature linear guide set: one 105 mm stainless-steel rail with a 12 mm wide running surface, a 15 mm end-hole offset for the fixing screws, and a single long (L) carriage travelling on it. Preload is grade A, meaning none, and the accuracy grade is H - high. The carriage arrives mounted on the rail, pre-filled with Kyodo Yushi PS No. 2 grease.
The long carriage is the point of this configuration: it spreads ball contact over a greater length, giving a longer bearing span that resists any tipping component in the load. The balls are ISO 3290 G10 Japanese steel for roundness and wear, the double-lip seal scrapes oil and excludes dust, the outer cover hides the screws and protects the seal strip, and the common-rail profile lets other LRM12 carriages share this rail. Keep ambient temperature at or below 80 C with peaks no higher than 100 C. Load and moment ratings are not published for LRM; send your application by RFQ and we confirm the figure for this exact set.

Where the Airtac LRM Miniature Linear Guide LRM12L1X105S15AH Is Used
Laboratory microplate handler
A compact liquid-handling deck that indexes a head across microplate wells fits the 105 mm travel envelope, with the smooth low-friction running of a single long carriage.
Small optical inspection XY stage
In a benchtop vision station, the long carriage helps keep a camera or sensor square over the 105 mm travel, resisting pitch as the stage moves along its short axis.
Miniature pick-and-place head
A light-duty placement head moving small electronic components along a short axis gets repeatable travel from the high accuracy grade and the 12 mm stainless rail.
Is the Airtac LRM Miniature Linear Guide LRM12L1X105S15AH the Right Guide?
With no published load table for LRM, sizing starts with a conversation. When the load is substantial or overhung - a vertical axis or a cantilevered head - move up to LSH, which publishes per-carriage dynamic, static and moment ratings you can calculate against; LRM gives you the small envelope but no numbers to size from. For short travel where rigidity comes from crossed rollers rather than recirculating balls, LGC is the cross-series alternative. Checklist for this set: complete form, 12 mm rail width, long carriage, one block, 105 mm rail length, preload A (none - the freest running but least rigid choice; light preload B adds stiffness at a small cost in drag), accuracy H, top-mount rail, and confirm the load rating with us before committing.
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 LRM12L1X105S15AH FAQ
Complete set: 12 mm wide stainless rail, 105 mm long, with a 15 mm end-hole offset; one long carriage; preload A (none); accuracy H (high); top-mount rail fixing. Mounting surfaces should be ground or finish-milled. Screw torque: M2 at 58.8 N.cm into steel (39.2 cast iron, 29.4 aluminium); M3 at 196 N.cm (127 cast iron, 98 aluminium). Ambient limit 80 C, peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months - at a short stroke cycled continuously, the distance arrives before the calendar does. Load and moment ratings are not published for LRM; we confirm them per model.
Choose LRM when the envelope is small and the duty is light - a 12 mm rail and a long carriage in a compact axis. LSH is the larger series and publishes per-carriage dynamic, static and moment ratings in its catalogue, which LRM does not, so a substantial or cantilevered load is sized there. If travel is very short and crossed-roller rigidity matters, LGC sits across rather than up. In every case, send us the load case so we confirm the rating for the specific LRM model before you order.
