Airtac LRM Miniature Linear Guide LRM12N1X245S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X245S10CP 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 LRM12N1X245S10CP
This code orders a matched set, not a spare part: the AirTAC LRM12N1X245S10CP arrives as one 12 mm wide, 245 mm stainless-steel rail with one standard-length ball carriage already fitted, precision grade accuracy, medium preload and a top-mount rail.
Precision grade P is the tighter of the two accuracy options on LRM, and it pairs here with medium preload - the stiffer, less forgiving choice, which trades a little running drag for reduced play. The carriage ships greased with Kyodo Yushi PS No. 2; top up through the rear lubrication hole every 100 km of travel or every 3 to 6 months, whichever comes first, and never mix lubricant types. The recirculating balls are ISO 3290 G10 Japanese-made, a grade that applies to the balls alone rather than to the assembled guide. No load or moment rating is published for the LRM series - describe your application in the RFQ and we will confirm the numbers for this exact model before you commit.

Where the Airtac LRM Miniature Linear Guide LRM12N1X245S10CP Is Used
Vision inspection camera slide
Carrying a small machine-vision camera along a scanned part, the slide must track straight enough that the lens stays square to the workpiece. Precision grade travel keeps the image repeatable between cycles.
Measuring fixture for machined parts
A bench gauge that slides a dial indicator or sensor across a finished part benefits from precision grade travel accuracy. Mount the rail on a ground or finish-milled surface to keep the reading honest.
Fiber-optic connector assembly stage
Positioning ferrules during connector assembly needs repeatable, light-touch motion. Medium preload reduces play so the alignment does not wander between cycles.
Is the Airtac LRM Miniature Linear Guide LRM12N1X245S10CP the Right Guide?
Match the guide to the task in two directions. Upward: if the payload is heavy or overhung, move to LSH, whose catalogue lists dynamic, static and moment ratings per carriage - figures LRM does not publish, so LSH lets you do the arithmetic. Across: for very short travel needing crossed-roller stiffness, LGC fits better. Checklist for this set: 12 mm rail width, 245 mm rail, one standard carriage, medium preload (rigid but less forgiving to install), precision grade accuracy, top-mount rail. Ask us to confirm the load rating for this exact model - we do it with every RFQ.
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 LRM12N1X245S10CP FAQ
Rail width 12 mm, rail length 245 mm, one standard-length carriage, precision grade accuracy, preload C (medium), top-mount rail. M3 fixing screws torque to 196 N.cm in steel, 127 N.cm in cast iron and 98 N.cm in aluminium; keep ambient temperature at or below 80 C, peaks to 100 C, and re-grease every 100 km of travel or every 3 to 6 months. What the catalogue does not give is any load, moment or speed rating for LRM - those are confirmed per model, so send us the RFQ and we will check your application.
A complete set: one 12 mm wide, 245 mm long stainless-steel rail with one standard-length ball carriage already fitted, precision grade, medium preload, mounting from the top. Nothing else is in the box - no extra carriages, no rail-only sections. If you later need a spare carriage on its own, carriage-only codes carry a pairing letter that must match the rail; we stock only four carriage-only SKUs, so most spares are special orders.
