Airtac LRM Miniature Linear Guide LRM12N1X445S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X445S10AP 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 LRM12N1X445S10AP
This SKU, the LRM12N1X445S10AP, is the precision-accuracy version of a 445 mm miniature guide set: a 12 mm wide stainless-steel rail carrying one standard-length ball carriage, ordered with no preload. Accuracy grade P is the tighter of the two grades AirTAC offers on this series, so travel over the full rail length is held straighter than an H-grade set of the same size. The carriage arrives on the rail, greased and ready to fix.
Inside the carriage the balls are Japanese-made to ISO 3290 G10 for roundness and wear - that grade describes the balls only, not the assembly. A double-lip seal manages oil scraping and dust exclusion, and an outer cover keeps larger debris off the seal strip while concealing the screws. Size 12 is where this range runs deepest: the large majority of listed LRM sets are 12 mm, so a design laid out around this rail width has the widest choice of lengths and configurations. Ambient temperature must stay at or below 80 C, peaking no higher than 100 C. LRM load and moment ratings are confirmed per model rather than published - send the RFQ and we will return the figures for this configuration.

Where the Airtac LRM Miniature Linear Guide LRM12N1X445S10AP Is Used
Semiconductor handler track
A chip handler moves trays or sockets along a straight path; precision-grade travel keeps the pick points aligned down the full 445 mm without recalibration.
Metrology gauge fixture
A measuring fixture carries a dial indicator or vision camera; the P accuracy grade supports repeatable readings without a compensation routine.
PCB vision alignment stage
A camera-based alignment axis slides a circuit board into register; the smooth ball circulation and double-lip sealing suit a clean electronics bench.
Is the Airtac LRM Miniature Linear Guide LRM12N1X445S10AP the Right Guide?
Decide by data, not by habit. If the load is heavy or hangs off a cantilever, move up to AirTAC LSH, which publishes dynamic, static and moment ratings per carriage that you can size against directly - LRM publishes none, so a heavier axis on LRM depends on our per-model confirmation. If the travel is short and the job needs crossed-roller stiffness rather than ball smoothness, look at LGC instead. For this set the checklist reads: complete set with rail included, 12 mm rail width, standard carriage, one carriage, 445 mm rail length, preload A (none), accuracy P (precision), top-mount fixing, plus a load rating confirmed with us before you commit. One planning note: spliced two-section rails are supplied in grade H only, so a P-grade axis must be a single-section rail - as this 445 mm one is.
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 LRM12N1X445S10AP FAQ
The set is a 12 mm wide, 445 mm long stainless rail with one standard-length carriage, no preload (A), precision accuracy (P), top-mount fixing and a 10 mm end-hole offset. Catalogue screw torques are 196 N.cm for M3 screws into steel, 127 N.cm into cast iron and 98 N.cm into aluminium, with M2 at 58.8, 39.2 and 29.4 N.cm. Regrease every 100 km of travel or every 3 to 6 months, and keep the ambient at or below 80 C. Basic dynamic load, static load and moment ratings are not published for LRM; we confirm them for this model on request.
Choose LRM when the envelope is tight and the duty is light - this 12 mm rail set is built for compact, precise positioning. Choose LSH when the load is substantial or overhung, because LSH carries published per-carriage dynamic, static and moment ratings that let you size on paper, while LRM has no published ratings and sizing stops at our confirmation. For short travels needing crossed-roller stiffness rather than ball smoothness, LGC is the third option.
