Airtac LRM Miniature Linear Guide LRM12N1X70S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X70S10AH 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 LRM12N1X70S10AH
The LRM12N1X70S10AH is a complete miniature linear guide: a single 70 mm stainless-steel rail, 12 mm wide, carrying one standard recirculating-ball carriage fitted at the factory and greased for first use. Top-mount fixing, with the end holes offset 10 mm.
Where this code earns its place is next to warm machinery. The published ambient ceiling is 80 C, with only brief excursions to 100 C allowed - a real constraint beside an oven door, a curing lamp or a laser head, and one of the very few hard figures LRM publishes. The 100 km re-grease interval is shorter than it sounds: a 70 mm stroke cycling once per second covers 100 km in under three weeks of continuous running, so the distance binds well before the 3 to 6 month calendar does. Carriages run on Japanese-made ISO 3290 G10 balls (the grade covers the balls only), retained in the carriage, sealed by a double lip and shielded by an outer cover. Load and moment ratings are confirmed for this model individually - ask us via the RFQ.

| N | Standard 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 LRM12N1X70S10AH Is Used
Compact label applicator head
A desktop label applicator pressing labels onto cartons or vials uses a short, light guide; 70 mm of rail covers the typical press-and-release stroke.
Cable and harness test traverse
Continuity test fixtures that traverse along a small cable or harness gain smooth, repeatable motion from a 70 mm miniature rail.
Vial sorting slide on a benchtop sorter
A benchtop vial sorter nudging vials between lanes runs a short slide all day; planning the 100 km re-grease point keeps the motion accurate.
Is the Airtac LRM Miniature Linear Guide LRM12N1X70S10AH the Right Guide?
Before you settle on a miniature ball guide, test two alternatives. LSH publishes per-carriage dynamic, static and moment ratings you can plug into a sizing calculation - the honest route when the load is heavy, offset or shock-loaded, because LRM offers no published figures at all. LGC answers a different question: very short travel where crossed-roller rigidity beats ball smoothness. Then verify this exact build: complete set with rail, 12 mm rail width, standard carriage, one carriage, 70 mm rail length, preload A (none), accuracy H, top-mount direction, end-hole offset 10 mm. Close the loop by confirming the load rating with us - send the RFQ and we will return the figures for this model.
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 LRM12N1X70S10AH FAQ
Respect the 80 C ambient limit (brief peaks to 100 C), bolt the rail down with correct torque - M2 screws 58.8 N.cm into steel, 39.2 N.cm into cast iron, 29.4 N.cm into aluminium; M3 screws 196, 127 and 98 N.cm - and re-grease every 100 km of travel or every 3 to 6 months through the rear lubrication hole. This set is a 12 mm wide stainless rail, 70 mm long, one standard carriage, preload A (none), accuracy H, top-mount, end holes offset 10 mm. Note that load and moment ratings are not published for LRM, so confirm them with us for this model.
When the duty stops being light. LRM publishes no load or moment ratings, so a heavy, cantilevered or shock-loaded mechanism should move to LSH, whose catalogue lists dynamic, static and moment ratings per carriage you can calculate against. A very short stroke needing crossed-roller stiffness points to LGC instead. If your sketch still fits a 12 mm rail with one standard carriage, send us the load and stroke and we will confirm whether the LRM12N1X70S10AH holds up.
