Airtac LRM Miniature Linear Guide LRM12N1X370S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X370S10CP 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 LRM12N1X370S10CP
LRM12N1X370S10CP is a complete AirTAC LRM set built around a 12 mm wide stainless-steel rail, 370 mm long, carrying one standard-length ball carriage. The carriage ships captive on the rail thanks to the ball-retention design, and the top-face mounting holes let you screw the rail down from above. This is the precision-grade version of the set - the P code in the ordering string.
Precision grade tightens the manufacturing tolerances on the pair, which matters when two of these guides run together on a measurement axis or a small XY stage: the travelling carriage tracks straighter over the 370 mm span. Preload grade C adds an interference fit of the balls, trading a little rolling drag for stiffness. The recirculating balls are ISO 3290 G10 Japanese balls for roundness, the double-lip seal manages lubrication and contamination, and an outer cover keeps chips off the seal strip. Keep the ambient at 80 C or below. AirTAC lists no load or moment rating for LRM anywhere in the catalogue, so we confirm the figures for this exact SKU before you commit - ask via the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X370S10CP Is Used
Compact XY inspection stage
A benchtop vision system pairing two precision-grade 12 mm guides gets repeatable camera positioning over a 370 mm axis without a full-size profile rail.
Small pick-and-place head
A PCB depaneling or IC pick-and-place slide benefits from the preloaded carriage resisting the tilt that would misalign a vacuum cup at pick.
Probe station axis
Laboratory wafer and substrate probe stations need repeatable, low-play travel; precision grade and medium preload both push repeatability in the right direction.
Is the Airtac LRM Miniature Linear Guide LRM12N1X370S10CP the Right Guide?
The P accuracy grade earns its keep when straightness of travel is the specification, not raw speed. Match this code on: complete set form, 12 mm rail width, standard carriage, single block, 370 mm rail, preload C (stiffer but less forgiving of imperfect seats), precision accuracy and top-mount holes. Mount on a ground or finish-milled face; either rail side can be the datum, and with a second guide alongside, keep both datum edges on the same side. When the payload is heavy or overhung, move up to LSH - it publishes dynamic, static and moment ratings per carriage that LRM simply does not have. For short travels needing crossed-roller rigidity, look at LGC. And before ordering, confirm the load rating with us; we will pull the per-model figure.
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 LRM12N1X370S10CP FAQ
Rail: stainless steel, 12 mm wide, 370 mm long, top-mount holes. Carriage: one, standard length. Preload: C (medium). Accuracy: P (precision). Screw torque: for M3 screws, 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium; M2 equivalents are 58.8, 39.2 and 29.4 N.cm. Ambient limit: 80 C, with transient 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 the LRM series - we confirm them per model, so ask us before you size the surrounding structure.
You receive the complete matched set: one rail with a single preloaded standard carriage already fitted. There is no separate carriage to pair and no pairing code to worry about. Handle the assembly flat and keep the carriage square to the rail - the ball-retention design reduces the risk of dropped balls but does not eliminate it, especially if the carriage is slid off at an angle or hastily. Wipe off the rust-preventive oil and charge the carriage with grease before first use.
