Airtac LRM Miniature Linear Guide LRM12L2X170S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X170S10AH is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriages. 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 LRM12L2X170S10AH
LRM12L2X170S10AH is a complete size 12 LRM set built around a 170 mm stainless-steel rail, 12 mm wide, with two long (L) carriages running on it. The A preload code means no preload at all, the H grade means high accuracy, and the absence of a trailing T puts the mounting holes on top, with a 10 mm end-hole offset. In the box: the rail with both carriages assembled, each charged with Kyodo Yushi PS No. 2 grease.
With no preload the balls roll free and the running drag is the lowest of the three grades, which suits axes you want to move with a light touch or drive with a small motor; the trade-off is a little internal play. This set is also a lesson in maintenance planning: the 100 km re-grease interval sounds long, but a 200 mm stroke cycling once per second covers that distance in roughly three weeks of continuous running, so the distance binds before the calendar does. Series design points include one rail profile shared by all carriage types, ball retention for safer handling, ISO 3290 G10 Japanese balls for roundness and wear, and a double-lip seal beneath an outer cover. The ambient limit is 80 C with transients to 100 C. No load or moment rating is published for LRM - request the confirmed per-model figures through the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L2X170S10AH Is Used
Cable and hose flex tester
A test carriage that cycles back and forth to exercise a cable or tubing sample. With preload A the drag stays minimal, so the drive sees only the test load, and the 170 mm stroke sets a repeatable bend cycle.
Micro dispensing head slide
A fluid dispensing head on a small gantry depositing adhesive dots on connector housings. The no-preload carriage glides with little resistance, letting a compact stepper position it precisely without overshoot.
Label applicator micro slide
A label applicator head swept across a 170 mm web path. Zero preload keeps friction low for fast cycling, and the double-lip seal holds grease in despite the dust that paper webs shed.
Is the Airtac LRM Miniature Linear Guide LRM12L2X170S10AH the Right Guide?
Match the checklist to your drawing: complete-set form, 12 mm rail width, 170 mm rail, two long carriages, preload A (zero - smoothest running, some internal play), accuracy H, top-mount. If the sizing maths stalls because you need numbers to calculate against, that is the signal to move to LSH, whose catalogue carries dynamic, static and moment ratings per carriage - figures LRM does not publish. LGC answers short-travel jobs where crossed-roller rigidity beats ball smoothness. Size 12 is the deepest part of the LRM range, so staying at 12 mm rather than 15 mm generally eases sourcing. Either way, confirm the load rating with us for this model 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 LRM12L2X170S10AH FAQ
Size 12 geometry: 12 mm rail width, 170 mm rail length, two long (L) carriages, 10 mm end-hole offset, no preload (A), high accuracy (H), top-mount fixing. Screws are M3: 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium. The ambient limit is 80 C with transients to 100 C. Re-lubricate every 100 km of travel or every 3 to 6 months; carriages arrive filled with Kyodo Yushi PS No. 2. There is no published load or moment rating for LRM - we confirm the figure for this model before you order.
If the carried mass is substantial or overhung, move to LSH: that series publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not. LRM12 earns its place when the envelope is tight and the duty is light - here a 170 mm rail with two long, no-preload carriages gives smooth, free-rolling travel for a small stage. For short travels needing crossed-roller rigidity, look at LGC instead. Send us the load sketch and we will confirm the LRM rating for this model.
