Airtac LRM Miniature Linear Guide LRM12N2X445S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X445S10CP 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 LRM12N2X445S10CP
The LRM12N2X445S10CP is a complete miniature linear guide set: one 445 mm stainless-steel rail, 12 mm wide, with two standard-length recirculating-ball carriages already fitted and a 10 mm end-hole offset. Fixed from above, preloaded to grade C (medium) and finished to precision accuracy grade P. In the box you get the rail and both carriages, assembled and ready to bolt down.
Two carriages on a single rail spread the load and resist tipping along the direction of travel, which is exactly why this layout suits compact stages that see small moment loads in service. The design runs on Japanese-made balls graded ISO 3290 G10 (that grade applies to the balls themselves, not to the guide assembly), behind double-lip seals for grease retention and dust exclusion, with an outer cover shielding the seal strip and screw heads. The common-rail profile means a replacement standard LRM12 carriage shares this same rail. Ambient temperature must stay below 80 C, with transients no higher than 100 C. A practical buying note: within the stocked LRM range, rail length rather than rail width is what moves the price, and LRM12 is by far the deepest part of our inventory, so this size ships fastest. AirTAC publishes no load or moment ratings for LRM; we confirm them for this exact model when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X445S10CP Is Used
Die bonder X-axis
A compact die bonder stepping its bonding head along a short, precise axis. The medium preload takes up clearance so the head stops where commanded, and two carriages on one rail keep the head square to the work.
Optical inspection XY stage
Building a small XY stage for PCB inspection cameras. The 445 mm single rail forms the long axis, precision grade P keeps the camera path straight, and the 12 mm rail width leaves room for optics and cabling.
Automated pipetting row
A laboratory pipetting robot moving a head across a microplate row. The stainless rail tolerates wiping down with mild lab cleaners, and the round G10 balls keep travel free of stick-slip at slow dosing speeds.
Is the Airtac LRM Miniature Linear Guide LRM12N2X445S10CP the Right Guide?
Size this set both ways before committing. When the load is substantial or cantilevered, step up to LSH: that series publishes per-carriage dynamic, static and moment ratings you can calculate against, which LRM does not offer at all. If the travel is short and the job needs crossed-roller rigidity rather than recirculating balls, LGC is the closer match. For this SKU, check the checklist in order: complete set with two standard carriages, 12 mm rail width, 445 mm rail length, preload C medium (stiffest running feel, but least tolerant of imperfect mounting surfaces, which must be ground or finish-milled), accuracy grade P precision, and top-mount fixing. LRM load and moment ratings are not published anywhere, so ask us by RFQ to confirm the figures for this exact model before you order.
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 LRM12N2X445S10CP FAQ
It is a complete set: one 445 mm stainless rail, 12 mm wide, carrying two standard-length carriages, fixed from above, with medium preload C and precision accuracy grade P. M3 assembly screws are torqued to 196 N.cm in steel, 127 N.cm in cast iron and 98 N.cm in aluminium, and the ambient temperature limit is 80 C with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months, quantities specified per model. One important gap: AirTAC publishes no dynamic load rating, no static load rating and no moment rating for LRM, so we confirm those figures for this specific model when you send the RFQ.
Both carriages come fitted on the rail - this is a single-guide complete set, not a twin-rail package and not a bare rail. The carriages share the common LRM rail profile, so a same-size standard carriage will fit this rail if one ever needs replacing. Bear in mind the ball-retention design reduces but does not eliminate dropped balls during fitting, so swap carriages carefully or use a dummy rail, and note that carriage-only replacements are usually a special order because our carriage-only stock is thin. Load ratings are not published for LRM; ask us by RFQ and we will confirm the figure for this model.
