Airtac LRM Miniature Linear Guide LRM12N1X70S10CPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X70S10CPT 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 LRM12N1X70S10CPT
AirTAC's LRM12N1X70S10CPT is a 12 mm-wide, 70 mm-long miniature guide set in which the rail is fastened from underneath - the trailing T in the code - leaving the top face free for travelling tooling, covers or product. One standard recirculating-ball carriage runs on the stainless rail at accuracy grade P for precision work, with preload C for a firm, low-rocking feel. Both parts arrive pre-assembled and pre-greased.
Bottom-mounting puts the machining burden on a seated groove or shoulder you can locate from below; whichever side of the rail you choose as the datum face, keep the datum on the same side for every carriage on shared assemblies to protect running accuracy. ISO 3290 G10 Japanese balls inside the carriage, a double-lip seal and an outer cover over the screw line keep the raceway clean and greased. The ambient ceiling is 80 C, with 100 C as a short peak. Because AirTAC publishes no load or moment table for LRM, the ratings for this exact model are confirmed with us before ordering - just send the duty.

Where the Airtac LRM Miniature Linear Guide LRM12N1X70S10CPT Is Used
Microscope sample stage
Beneath a benchtop inspection microscope, the bottom-fixed 70 mm rail advances samples under the objective with the mechanism hidden below the stage plate.
Fibre alignment fixture
A precision-P carriage nudges an optical fibre into a coupler by fractions of a millimetre, with the C preload holding position once aligned.
Probe carriage on a gauge bench
A dial or electronic probe rides the 12 mm rail across a workpiece, the bottom-mount fixing keeping the measuring line low and clear of clamps.
Is the Airtac LRM Miniature Linear Guide LRM12N1X70S10CPT the Right Guide?
Treat LRM as the light-duty, small-envelope end of the range. A heavy or overhung load belongs on LSH, whose catalogue lists dynamic, static and moment ratings per carriage - numbers LRM simply does not have. Crossed-roller rigidity over a short travel is LGC territory. For this SKU tick off: set form, 12 mm rail width, standard carriage, single block, 70 mm rail, preload C (rigid but intolerant of poor seats), accuracy P, bottom-mount direction, then confirm the load rating with us.
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 LRM12N1X70S10CPT FAQ
Rail 12 mm wide by 70 mm long, one standard carriage, preload C, accuracy P, bottom-mount rail, 10 mm first-hole offset. Screw torque into steel: 58.8 N.cm for M2 and 196 N.cm for M3 screws, less for cast iron and aluminium. Re-grease after each 100 km of travel or every 3 to 6 months; the ambient must not exceed 80 C with 100 C peaks. Load and moment ratings are not published for LRM - we confirm them per model.
Stay with LRM12 when space is tight and the positioning duty is light; move to LSH when you need a manufacturer-published load, static or moment rating to calculate against, since LRM's capacity is only confirmed per model through us. Note that LRM12 is what we stock in depth - 924 stocked sets - so this configuration typically ships faster than an equivalent special-order build.
