Airtac LRM Miniature Linear Guide LRM12L1X170S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X170S10AP 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 LRM12L1X170S10AP
LRM12L1X170S10AP is the precision-grade version of this layout: a 12 mm wide stainless-steel rail, 170 mm long, carrying a single long recirculating-ball carriage, preload A (none), accuracy P (precision) rather than the standard high grade, and top-mount rail fixing. Where a drawing calls out tighter control of travel accuracy instead of just a smooth-running axis, P is the grade that answers it.
Precision grade only pays off on a prepared base: the mounting surface must be ground or finish-milled to realize the rated travel accuracy, and the rail must never be struck or dropped - accuracy and service life can suffer with no visible damage. Inside, Japanese-made balls graded ISO 3290 G10 (a grade for the balls themselves, not the assembly) run under a double-lip seal with an outer cover protecting the seal strip and screws. Ambient temperature must stay at or below 80 C, with transient peaks to 100 C. Load and moment ratings are not published for LRM; ask us and we confirm the figures for this exact model before you order.

| L | Long carriage. |
| 1X170 | 1 carriage on a 170 mm rail. |

Where the Airtac LRM Miniature Linear Guide LRM12L1X170S10AP Is Used
Small-part measuring fixture
A bench fixture positioning small machined parts under an indicator; the precision grade supports repeatable comparison measurements.
Optical bench filter slider
Sliding filters or neutral-density mounts across a laser path in a laboratory setup; precise, repeatable travel keeps beam alignment intact.
Connector test head slide
Lowering a small test head onto electronics assemblies; the long carriage keeps the head square to the board through the stroke.
Is the Airtac LRM Miniature Linear Guide LRM12L1X170S10AP the Right Guide?
Start from the tolerance stack: if your machine genuinely needs the tighter P grade, this is the right SKU; if high accuracy H suffices, the H version of the same code is the more economical route. Then check the neighbours - AirTAC LSH when loads are substantial or cantilevered (LSH publishes per-carriage dynamic, static and moment ratings; LRM does not), and LGC when the travel is short and crossed-roller rigidity matters. Before ordering, tick off: complete set form, 12 mm rail width, long carriage, one block, 170 mm rail length, preload A for the freest running feel, accuracy P, top-mount direction, and a load rating confirmed 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 LRM12L1X170S10AP FAQ
Published here: 12 mm rail width, 170 mm rail length, one long carriage, preload A (none), accuracy P (precision), top-mount rail fixing, and an ambient temperature limit of 80 C with transient peaks to 100 C. Carriages are pre-filled with Kyodo Yushi PS No. 2; re-grease every 100 km of travel or every 3 to 6 months without mixing lubricant types. Mounting surfaces must be ground or finish-milled. What is not published: load and moment ratings for LRM. We confirm them for this specific model through the RFQ before you commit.
For a miniature envelope with light duty, LRM in P grade is the sharper tool - the range exists for small, smooth, accurate positioning. Once the load becomes substantial or overhung, LSH is the better engineering choice because it publishes per-carriage dynamic, static and moment ratings you can size against, whereas LRM figures are confirmed per model. Short travel with crossed-roller rigidity in mind points to LGC instead. Send the load case with your enquiry and we will settle the series with you.
