Airtac LRM Miniature Linear Guide LRM12L1X65S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X65S10AH 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 LRM12L1X65S10AH
LRM12L1X65S10AH is a complete LRM miniature linear guide from AirTAC: one 12 mm wide stainless-steel rail, cut to 65 mm, carrying a single long (L) recirculating-ball carriage. The S10 in the code sets a 10 mm screw-hole offset from each end of the rail. It arrives as one assembled unit - rail, carriage, double-lip seals and outer cover all fitted - so there is nothing extra to buy for a single short axis.
Three things make this stubby little set workable. The common-rail profile means any LRM12 carriage shares this rail, so a future carriage swap is straightforward; ball retention keeps the Japanese-made ISO 3290 G10 balls (a ball grade only, not a standard for the assembly) from spilling during that swap, though careful, square insertion is still needed. The 80 C ambient limit - 100 C in brief peaks - is the one published environmental figure, and it matters near lamps or warm enclosures. AirTAC publishes no load or moment rating for LRM, so we confirm the figures for this exact model before you order - send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X65S10AH Is Used
Compact XY alignment stage
A 65 mm axis slides a laser-diode or sensor carrier a few millimetres in each direction inside a benchtop inspection unit; the long carriage suits such a short rail better than a standard block would.
Micro-pipetting head slide
In a small liquid-handling instrument, the guide positions a lightweight pipette head over a well plate with repeatable motion at room temperature, comfortably inside the 80 C ambient limit.
Machine-vision focus slide
A camera on an electronics test rig rides the axis to refocus between inspection heights; the motion is light, smooth and occasional, exactly the duty this miniature guide is built for.
Is the Airtac LRM Miniature Linear Guide LRM12L1X65S10AH the Right Guide?
For anything beyond a light payload, or any cantilever, move up to the LSH series - LSH publishes per-carriage dynamic, static and moment ratings you can actually size against, something LRM deliberately leaves out. Where travel is very short and you want crossed-roller stiffness instead of recirculating balls, look at LGC. Ordering checklist for this SKU: complete-set form, 12 mm rail width, 65 mm rail length, one long carriage, preload A (none - the least rigid and the easiest to slide, right for free-moving stages, wrong where stiffness is critical), accuracy H, top-mount rail. Send the duty details with your RFQ and we confirm the rating before you commit.
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 LRM12L1X65S10AH FAQ
Published: 12 mm rail width, 65 mm rail length, one long (L) carriage, 10 mm end-hole offset, preload A (none), accuracy H, top-mount rail. Fastening torque: M2 screws 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 screws 196, 127 and 98 N.cm respectively. Ambient limit 80 C, brief peaks 100 C. Re-grease with Kyodo Yushi PS No. 2 every 100 km of travel or every 3 to 6 months. Not published: basic dynamic load, static load and moment ratings - AirTAC omits them for LRM, and we confirm the figures for this model when you send the RFQ.
It is complete for one axis: the 65 mm stainless-steel rail and the single long carriage arrive assembled and pre-greased, with seals and outer cover fitted. You supply only the fixing screws and a prepared mounting surface. If you ever need a spare carriage on its own, note that our carriage-only stock is thin - a handful of SKUs - so most replacements are a special order matched to the pairing code of the original.
