Airtac LRM Miniature Linear Guide LRM12N1X245S10CH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X245S10CH 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 LRM12N1X245S10CH
The LRM12N1X245S10CH is an AirTAC LRM complete set built around a stainless-steel rail 12 mm wide and 245 mm long, with one standard-length recirculating-ball carriage. Its C preload makes it the firmest running option in the LRM range - there is no grade above medium on this series.
Medium preload tightens the internal clearance, which damps play under reversing loads but raises sliding friction slightly and forgives mounting misalignment less - weigh that against hand-adjusted or lightly loaded stages. The carriage runs on ISO 3290 G10 Japanese balls behind a double-lip seal, with an outer cover hiding the fixing screws. At 245 mm this rail sits well inside the 1005 mm catalogue maximum for size 12, and LRM12 is by far the deepest stocked size in the range, so lead times are usually short. Ambient limit is 80 C (100 C transient). AirTAC publishes no LRM load or moment ratings; we confirm them for this model via the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X245S10CH Is Used
Tabletop sorter lane
A small parts sorter reverses direction many times a minute; C medium preload stops the carriage knocking through clearance at each reversal, holding the lane line steady.
Desktop screwdriving slide
A compact screwdriving head sees a sharp downward reaction at every fastener; the firmest LRM preload helps the carriage resist that brief tipping effect on a 245 mm stroke.
Label applicator head
On a benchtop labelling machine the head crosses the product on a 245 mm axis; H high accuracy keeps the label edge square to the pack run after run.
Is the Airtac LRM Miniature Linear Guide LRM12N1X245S10CH the Right Guide?
For substantial or cantilevered loads, step up to AirTAC LSH, which publishes per-carriage dynamic, static and moment ratings to size against - LRM publishes none. If the stroke is short and the design needs crossed-roller rigidity, LGC is the nearer match. Check each item: set form, 12 mm rail, standard carriage, single block, 245 mm length, C medium preload (the stiffer, less forgiving choice), H high accuracy, top-mount rail. Also trim rail length before rail size - nearly all of the roughly $66 to $831 spread across the stocked range comes from length and carriage count, not width. Confirm the load rating with us before ordering.
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 LRM12N1X245S10CH FAQ
Rail width 12 mm, rail length 245 mm, one standard-length carriage, C medium preload, H high accuracy, top-mount rail. M3 fixing screws torque to 196 N.cm into steel, 127 into cast iron and 98 into aluminium; M2 screws to 58.8, 39.2 and 29.4 N.cm. Ambient temperature must stay under 80 C, with peaks to 100 C, and lubrication is renewed every 100 km of travel or every 3 to 6 months. Dynamic, static and moment load ratings are not published for LRM - ask us and we confirm them for this model before you order.
LRM is the compact light-duty choice - this 12 mm, 245 mm rail trades published ratings for a small envelope, retained balls and smooth H-grade travel. LSH is the step up when loads are real or overhung, since it publishes per-carriage dynamic, static and moment ratings you can put into a sizing calculation. Either way, tell us the load, moment and duty through the RFQ and we confirm the ratings for the exact model before you commit.
