Airtac LRM Miniature Linear Guide LRM12L1X195S10CH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X195S10CH 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 LRM12L1X195S10CH
LRM12L1X195S10CH is a complete AirTAC LRM miniature linear guide in the 12 mm size: one 195 mm stainless-steel rail with a 10 mm end-hole offset, supplied with a single long (L) recirculating-ball carriage already fitted, ready to bolt down from above. The rail width is 12 mm, and in this series the size code equals the physical rail width.
Two choices shape this build. The long body carries its recirculating balls over a bigger footprint than the standard block, which steadies any tipping tendency along the travel, and the medium preload grade C takes out the play for a firmer, less forgiving running feel. The balls are Japanese made to ISO 3290 G10 for roundness, held in place by the ball-retention design so they stay put during handling, while a double-lip seal and an outer cover keep oil in and debris out. Ambient temperature must stay at or below 80 C, with transient peaks no higher than 100 C - worth checking if the guide sits near a heater or a hot plate. The manufacturer publishes no load or moment figures for LRM; we confirm the rating for this exact model before you order, so send us the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X195S10CH Is Used
Compact XY glue-dispensing stage
On a desktop dispensing machine tracing adhesive dots across small PCBs, the long carriage on this 195 mm rail resists the tipping that a short block can show as the head changes direction at each dot.
Laser alignment carriage on an optics bench
A 12 mm rail on a breadboard gives a smooth, play-free slide for a fold mirror or beam splitter. Preload C removes slop so the reflected beam does not wander between adjustments.
Small pick-and-place Z head
Light vacuum heads for chips and connectors run cleanly on a 12 mm guide. Because LRM load ratings are not published, send us the head mass and stroke and we confirm the rating for this model first.
Is the Airtac LRM Miniature Linear Guide LRM12L1X195S10CH the Right Guide?
LRM carries no published dynamic, static or moment rating, so do not size it by guesswork. If the load is substantial or hangs off a cantilever, step up to AirTAC LSH, which publishes per-carriage dynamic, static and moment ratings you can check directly against your numbers. Where travel is short and crossed-roller rigidity matters more than stroke, LGC is the closer match. Before you commit, work the checklist: complete set with rail, 12 mm rail width, long carriage, one block per rail, 195 mm rail length, preload C (stiff, but less tolerant of mounting misalignment), accuracy H, top-mount fixing - and ask us to confirm the load 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 LRM12L1X195S10CH FAQ
Rail width 12 mm; rail length 195 mm with a 10 mm end-hole offset; one long (L) carriage; medium preload grade C; high accuracy grade H; top-mount rail fixing. Fixing-screw torque: M3 - 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium; M2 - 58.8, 39.2 and 29.4 N.cm respectively. Ambient temperature must not exceed 80 C (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 before ordering.
One 195 mm stainless-steel rail and one long LRM12 carriage already mounted on it - a complete, working guide, not a carriage or rail sold separately. The carriage ships pre-filled with Kyodo Yushi PS No. 2 grease; wipe off the rust-preventive oil, re-lubricate, and you are ready to run. The ball-retention design keeps the balls captive during handling, but fit the carriage squarely and slowly - angled or hasty fitting can still drop balls, and a dummy rail helps if you ever need to take it off.
