Airtac LRM Miniature Linear Guide LRM12N1X120S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X120S10CP 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 LRM12N1X120S10CP
LRM12N1X120S10CP is a complete miniature guide set built for measurement-grade work: a 12 mm wide stainless-steel rail, 120 mm long, with one standard-length recirculating-ball carriage, medium preload (grade C) and precision accuracy (grade P). Top-mount fixing means the screws pass through the top face of the rail. The P grade is the tighter of the two accuracy classes offered on LRM, chosen where the running accuracy of the travel feeds directly into the process result.
Both H and P grades are stocked in this width, so specifying precision does not slow the order - and because rail length rather than width drives the price of stocked sets (roughly $66 to $831 across just two widths), a short 120 mm rail keeps the cost near the bottom of that span. Inside the carriage, Japanese ISO 3290 G10 balls (the grade covers the balls alone) run on retained tracks behind a double-lip seal, with an outer cover over the screw line keeping chips and larger debris off the seal strip. The ambient must stay at or below 80 C, peaking to 100 C at most. Load and moment ratings are not published for LRM; we will confirm the figure for this exact model when the RFQ arrives.

Where the Airtac LRM Miniature Linear Guide LRM12N1X120S10CP Is Used
Optical lens positioning stage
Setting a lens or mirror at a fixed station benefits from the P accuracy grade, which keeps the carried optic truer along the 120 mm travel than the standard H grade.
Die and wafer piece inspection
At a semiconductor piece-part inspection bench, a precision-graded slide supports repeatable repositioning of small dies under a microscope without re-teaching the position.
Benchtop gauge fixture
A go/no-go or comparator fixture built on a 120 mm precision slide holds its setting through the shift, helped by the medium preload taking out clearance.
Is the Airtac LRM Miniature Linear Guide LRM12N1X120S10CP the Right Guide?
Price in this series is driven by rail length far more than by size: stocked sets span roughly $66 to $831 across just two widths, and a 120 mm rail sits near the bottom of that span - trim travel before you upsize. For loads that are heavy or cantilevered, move up to LSH, which publishes per-carriage dynamic, static and moment ratings you can size from; LRM publishes none of these. Where travel is short and crossed-roller rigidity beats ball running, LGC is the alternative. Your checklist for this SKU: complete set, 12 mm rail width, standard carriage, one block, 120 mm rail, preload C (the rigid, less forgiving choice), P accuracy, top-mount direction, and a confirmed load rating from us before you commit.
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 LRM12N1X120S10CP FAQ
A 12 mm wide stainless rail 120 mm long, one standard-length carriage, preload grade C (medium), accuracy grade P (precision) and top-mount fixing. Mounting torques: M2 screws 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 screws 196, 127 and 98 N.cm. Ambient temperature must not exceed 80 C with transient peaks to 100 C. The carriage ships pre-filled with Kyodo Yushi PS No. 2 - re-grease every 100 km of travel or every 3 to 6 months, never mixing lubricant types. Load and moment ratings are not published for LRM; send the RFQ and we confirm the numbers for this model.
No - the 120 mm rail and its single standard carriage arrive as one matched unit, with the carriage already running on the rail. Treat the ball-retention feature as a handling aid only: fitting or removing the carriage at an angle, or quickly, can still drop balls, and the manufacturer suggests a dummy rail for awkward insertions. Note also that we stock only four carriage-only SKUs across the range, so a future spare carriage is usually ordered specially rather than pulled from the shelf.
