Airtac LRM Miniature Linear Guide LRM12L1X200S12.5AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X200S12.5AH 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 LRM12L1X200S12.5AH
LRM12L1X200S12.5AH is a complete LRM miniature guide set: a stainless-steel rail 12 mm wide and 200 mm long, drilled with a 12.5 mm end-hole offset and fixed from above, carrying one long recirculating-ball carriage delivered assembled and pre-filled with Kyodo Yushi PS No. 2. Preload A means none - the carriage runs with the lowest drag of any grade in the range, which suits axes that are adjusted by hand, driven by light actuators, or simply expected to glide.
The long carriage spreads its ball contact over a greater footprint, which helps where a carried part must not pitch along the travel. The recirculating balls are Japanese-made to ISO 3290 G10 - that grade covers the balls only, not the assembly's accuracy class. Accuracy here is H, the high tier, with top-mount fixing. A double-lip seal manages oil retention and dust exclusion, and an outer cover keeps larger debris off the seal strip. Keep the surroundings at or below 80 C - this is the one published environmental figure for the series, and it matters next to a heater, an oven door or a laser. No load or moment rating is published for LRM; we will confirm the figure for this exact model when you enquire.

Where the Airtac LRM Miniature Linear Guide LRM12L1X200S12.5AH Is Used
Bolt-down machine-vision camera track
A camera track on an automated test bench, where the free-running A preload lets the camera glide between inspection stops smoothly and without overshoot at the end of travel.
Ageing lab jig retrofit
Upgrading a worn laboratory jig: the 200 mm rail drops into a layout drawn around a 12 mm profile, restoring smooth travel without redesigning the mounting hole pattern.
Glovebox sample shuttle
A sample shuttle inside a glovebox moving small vials between ports, chosen partly because the sealed double-lip design and the 80 C ambient limit suit enclosed, mildly warm environments.
Is the Airtac LRM Miniature Linear Guide LRM12L1X200S12.5AH the Right Guide?
For heavier or cantilevered duties, move to AirTAC LSH, whose catalogue publishes per-carriage dynamic, static and moment ratings you can size against directly - LRM publishes none, which is exactly why we confirm figures per model instead. For short travel needing crossed-roller rigidity, LGC is the alternative. Before ordering this set, work the checklist: form (complete set), 12 mm rail width, long carriage, one carriage, 200 mm rail length, preload A with its trade-off (freest running, but no clearance removal - pick a higher grade if play must be eliminated), accuracy H, top-mount mounting. A set needs no pairing code. Then confirm the load rating with us against your actual duty; that step substitutes for the missing published table.
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 LRM12L1X200S12.5AH FAQ
This set uses a 12 mm wide rail, 200 mm long, with one long carriage, preload A (none), accuracy H (high), top-mount fixing and a 12.5 mm end-hole offset. Screw torques: M2 58.8 N.cm into steel, 39.2 N.cm into cast iron, 29.4 N.cm into aluminium; M3 196, 127 and 98 N.cm respectively. The ambient temperature limit is 80 C with transient peaks of 100 C. Re-grease every 100 km of travel or every 3 to 6 months through the rear lubrication hole, never mixing grease types. Load and moment ratings are not published for LRM; we confirm them per model on request.
The complete pair: a 200 mm stainless-steel rail and one long recirculating-ball carriage, assembled and pre-greased - a working axis out of the box. It is not a carriage alone; carriage-only codes carry the letters BK and a pairing letter that must match the rail, and only a few of those are held, so a spare carriage is normally a special order. Note also that the manufacturer's ball-retention design reduces, but does not eliminate, the chance of dropped balls during carriage fitting - work slowly or use a dummy rail.
