Airtac LRM Miniature Linear Guide LRM12L1X70S10AHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X70S10AHT 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 LRM12L1X70S10AHT
The trailing T in LRM12L1X70S10AHT means the rail is fixed from below instead of from above - the right choice when the deck above the guide must stay clear. Everything else is standard LRM12 fare: a 12 mm wide stainless rail cut to 70 mm, one long recirculating-ball carriage, high accuracy, no preload, and a 10 mm screw-hole offset at each end. The set ships assembled, seals and covers in place.
Two installation notes earn their place here. Mounting surfaces should be ground or finish-milled to reach the rated travel accuracy, and if a second carriage is added later, the datum edge goes on the same side of the rail for both. Handle the carriage on an inclined rail with a hand on it - it can slide off under its own weight. Balls are Japanese-made and graded ISO 3290 G10 (the balls alone), the seal is a double lip, and the ambient limit is 80 C. Load and moment values are not published for LRM, so we confirm them for this model against your RFQ before you commit.

| L | Long carriage. |
| 1X70 | 1 carriage on a 70 mm rail. |
| S… | End-hole offset from the rail end, in mm. |
| A | A — no preload — higher preload raises rigidity and tightens how flat the mounting surface must be. |

Where the Airtac LRM Miniature Linear Guide LRM12L1X70S10AHT Is Used
Under-deck sensor bracket
A through-beam sensor bracket mounts beneath a small conveyor deck; the bottom-mount rail fixes from below so the working surface above the guide stays clear for product flow.
Gauge fixture slide
A first-article inspection fixture on a milling bench slides a part in front of a height gauge; a ground fixture plate gives the mounting accuracy this guide expects to hold its travel precision.
Dispenser head retrofit
Retrofitting an older glue-dispensing bench: the underside fixing lets the new 70 mm rail drop into a slot machined in the base plate without touching the top deck of the machine.
Is the Airtac LRM Miniature Linear Guide LRM12L1X70S10AHT the Right Guide?
Start by asking whether you need published numbers: if the answer is yes, the LSH series carries them (per-carriage dynamic, static and moment ratings) while LRM does not, so substantial or cantilevered duties belong on LSH. If the stroke is short and the priority is crossed-roller rigidity rather than ball smoothness, LGC is the alternative. For this bottom-mount set, check: complete-set form, 12 mm rail width, 70 mm rail length, long carriage, preload A (lowest drag, lowest rigidity), accuracy H, underside fixing. The load rating is confirmed per model - include the duty in your 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 LRM12L1X70S10AHT FAQ
The rail is 12 mm wide and 70 mm long, with one long carriage, preload A (none), H-grade accuracy and fixing from below via 10 mm offset holes. Use 58.8 N.cm for M2 screws in steel (39.2 cast iron, 29.4 aluminium) or 196 N.cm for M3 (127, 98). Keep ambient at 80 C or less, peaks 100 C. Grease - Kyodo Yushi PS No. 2 - is refreshed every 100 km of travel or every 3 to 6 months; with this axis's short stroke, the calendar will usually arrive first. Load and moment ratings are not published for LRM: we confirm them for this exact model via the RFQ.
You receive one assembled set: a 70 mm stainless rail and a single long carriage, pre-filled with grease, seals and covers in place - no separate parts to order. The T in the code means the mounting direction is bottom-mount: the rail fixes from below, which suits frames where the top face must remain unobstructed. Prepare the mounting surface by grinding or finish milling, and if you add a second carriage later, keep both datum edges on the same side of the rail.
