Airtac LRM Miniature Linear Guide LRM12N1X95S10AHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X95S10AHT 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 LRM12N1X95S10AHT
LRM12N1X95S10AHT is the bottom-mount variant of the 95 mm, 12 mm wide LRM12 set: the trailing T in the code means the rail fixes from below the mounting surface, suiting assemblies where screws cannot be reached from above. One standard carriage, high H accuracy, stainless-steel rail, delivered assembled as a complete set.
For best running accuracy, put the datum edge of the rail and the datum edge of the table on the same side, and if you later add carriages keep every datum on that same side. Handling deserves care: the ball-retention design helps, but the manufacturer is explicit that inserting the carriage at an angle or rushing the fit can still drop balls, so work slowly or use a dummy rail. The recirculating balls are Japanese ISO 3290 G10 grade - a specification of the balls only - behind a double-lip seal protected by an outer cover. Ambient temperature is capped at 80 C with 100 C short peaks, a real constraint beside curing ovens or solder rework benches. No load or moment rating exists in the LRM catalogue; we confirm the figures for this exact configuration via the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X95S10AHT Is Used
Under-plate metrology slide
Bolts up beneath a granite inspection plate so the top face stays clear for workpieces and probes, with the rail fixing hidden from the working side.
Fibre polish fixture
Indexes a fibre-optic connector polishing head on a jig where proud screw heads above the rail would snag the cable loom.
Wafer-handling hood slide
Inside a semiconductor lab hood, the outer cover keeps particles off the seal strip while a wafer shuttle moves a short, gentle stroke.
Is the Airtac LRM Miniature Linear Guide LRM12N1X95S10AHT the Right Guide?
Choose LSH when the load is real - its catalogue lists dynamic, static and moment ratings per carriage, letting you do the arithmetic LRM cannot support. Choose LGC when travel is short and you want the stiffness of crossed rollers in a small footprint. For this SKU check each choice: it is a complete set (rail plus one block), rail width 12 mm, standard carriage length, one carriage on a 95 mm rail, no preload, high H accuracy and bottom-mount fixing. Replacing a single block elsewhere? You will need its pairing code. Confirm the load rating with us via RFQ before finalising the design.
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 LRM12N1X95S10AHT FAQ
The trailing T sets bottom-mount fixing: the rail bolts up from below the mounting surface instead of from the top. The rest of the specification is a 12 mm wide stainless rail 95 mm long, end holes 10 mm from the ends, one standard carriage, preload grade A (none) and accuracy grade H (high). Fixing torque: M2 screws 58.8 N.cm into steel, 39.2 N.cm into cast iron, 29.4 N.cm into aluminium; M3 screws 196, 127 and 98 N.cm. Keep the ambient at or below 80 C (100 C peaks) and re-grease with Kyodo Yushi PS No. 2 every 100 km or every 3 to 6 months. Load and moment ratings are not published for LRM; we confirm them per model via the RFQ.
It is a complete set - the 95 mm rail and its single standard carriage ship together, assembled, with the bottom-mount hole pattern already in the rail. Carriage-only parts use a different code that carries a pairing letter instead of a rail length; the letter must match the rail for the block to seat correctly. Because we stock very few carriage-only SKUs, a replacement block is normally a special order - send us the code on your existing set and we will quote the match.
