Airtac LRM Miniature Linear Guide LRM12L2X495S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X495S10AH 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 LRM12L2X495S10AH
LRM12L2X495S10AH is a complete miniature linear guide set from AirTAC: one 12 mm wide stainless-steel rail, cut to 495 mm, carrying two long (L) carriages that run on recirculating steel balls. End-fixing holes are offset 10 mm from the rail ends, and the guide bolts down from the top. What arrives is the assembled set - rail plus both carriages.
AirTAC builds the LRM family around a common rail profile, so any standard LRM12 carriage shares this rail, and a ball-retention design keeps the balls in place during careful handling. The balls themselves are Japanese-made ISO 3290 G10 grade for roundness and wear. A double-lip seal scrapes oil and excludes dust, while an outer cover shields the seal strip and screw heads from larger debris. Keep the ambient temperature at or below 80 C, with brief peaks to 100 C. No load or moment rating is published for LRM - we confirm the figures for this exact model when you send an RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L2X495S10AH Is Used
Vision inspection stage
A compact XY stage for camera-based checks of moulded connector pins: the two long blocks keep the moving plate flat over a stroke of a few hundred millimetres on the 495 mm rail, and top-mount fixing suits a plain aluminium base plate.
Autosampler gantry
A laboratory autosampler moving a probe head between vial trays: preload grade A slides freely with low drag, useful where a drive belt positions the head and sticky motion would upset dispensing repeatability.
Test-fixture slide
A slide in a small electronic test rig that presents PCB assemblies to a pogo-pin head; the long carriage gives a stable platform for the fixture plate as it docks under the contact block.
Is the Airtac LRM Miniature Linear Guide LRM12L2X495S10AH the Right Guide?
Because LRM publishes no dynamic, static or moment ratings, sizing against real loads means asking us. If your carriage carries substantial or cantilevered weight, step up to the LSH series, which publishes per-carriage ratings you can calculate with; if the travel is short and you need crossed-roller rigidity instead of ball recirculation, compare LGC. Availability is on your side with this code: size 12 dominates our LRM stock (924 of 988 sets), so this configuration ships quickly. Also mind the re-grease interval - 100 km sounds long, but a 200 mm stroke cycling once per second reaches it in roughly three weeks of continuous running.
Check before ordering: form (complete set), 12 mm rail width, long carriage, two blocks, 495 mm rail, preload A (free sliding, easiest to install but the least rigid under changing loads), accuracy H, top-mount holes. Send the load and moment figures with your RFQ and we will confirm the rating for this model.
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 LRM12L2X495S10AH FAQ
Rail width 12 mm, rail length 495 mm, two long (L) carriages, 10 mm end-hole offset, preload A (none), accuracy grade H, top-mount rail fixing. M3 mounting screws torque to 196 N.cm in steel, 127 N.cm in cast iron and 98 N.cm in aluminium. Ambient temperature must not exceed 80 C, with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM; we confirm them per model.
Choose LRM when the envelope is tight and the job is light-duty precision positioning - this 12 mm set keeps the profile slim and the motion smooth. Choose LSH when loads are heavier or overhung: LSH publishes dynamic, static and moment ratings per carriage that you can size against, while LRM publishes none and every figure must be confirmed per model with us. If you are unsure, send the load, moment and stroke to our RFQ desk and we will name the right series.
