Airtac LRM Miniature Linear Guide LRM12N2X195S10CH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X195S10CH 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 LRM12N2X195S10CH
The LRM12N2X195S10CH arrives as a complete miniature linear guide: one 12 mm stainless-steel rail, machined 195 mm long with fixing holes 10 mm in from each end, carrying two standard-length recirculating-ball carriages. Nothing else to order - rail and blocks are supplied together, ready to bolt down onto a ground or finish-milled mounting face.
Preload grade C is the medium grade and the firmest LRM offers. It removes play for a more confident feel under reversing loads, but it is less forgiving of flatness errors on the mounting surface than the free-rolling A grade, so prepare the face accordingly. Inside, ball retention keeps the ISO 3290 G10 Japanese-made balls seated during handling, a double-lip seal scrapes lubricant and excludes dust, and an outer cover shields the seal strip and screw heads. Keep the ambient temperature at or below 80 C, with short peaks no higher than 100 C. AirTAC publishes no load or moment rating for LRM; the figure for this exact model is confirmed individually, so send the RFQ and we will come back with it.

Where the Airtac LRM Miniature Linear Guide LRM12N2X195S10CH Is Used
PCB dispensing stage
On a compact desktop dispensing cell, two blocks on one 195 mm rail keep the glue head from nodding as it stops and starts over the board.
Photonics lab alignment slide
A 195 mm slide under a beam-splitter mount gives a bench-top optics rig a smooth, repeatable trim adjustment without bulky hardware.
Micro-part inspection fixture
Grade C preload removes play under a dial or camera probe checking small turned parts, so readings do not wander between approaches.
Is the Airtac LRM Miniature Linear Guide LRM12N2X195S10CH the Right Guide?
If the load is substantial or hangs on a cantilever, step up to the LSH series: it publishes per-carriage dynamic, static and moment ratings you can size against, which LRM deliberately does not. Where travel is short and the job demands crossed-roller rigidity instead, LGC is the closer match.
For this part, run the checklist: form - complete set; rail width 12 mm; standard carriages, two per rail; rail length 195 mm; preload C, accepting the tighter mounting-surface requirement; accuracy H; top-mount direction. Then confirm the load rating with us 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 LRM12N2X195S10CH FAQ
Rail width is 12 mm and the rail is 195 mm long, topped with two standard-length carriages. Preload is grade C (medium), accuracy grade H (high), and the rail mounts from above with holes 10 mm from each end. Fasten with M3 screws at 196 N.cm into steel, 127 N.cm into cast iron or 98 N.cm into aluminium. The carriages leave the factory pre-filled with Kyodo Yushi PS No. 2; re-grease every 100 km of travel or every 3 to 6 months. Ambient temperature must not exceed 80 C. One caveat: AirTAC publishes no load or moment ratings for LRM, so we confirm those for this model individually - just ask.
Choose LSH when the load is heavy, offset or cantilevered, because LSH publishes dynamic, static and moment ratings per carriage that you can verify against your duty cycle. LRM, including this set, is the choice when a tight envelope, smooth light-duty travel and a 12 mm rail matter more than a published capacity table. If you cannot decide, send us the load, span and duty and we will size it with you.
