Airtac LRM Miniature Linear Guide LRM12L1X470S10APT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X470S10APT 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 LRM12L1X470S10APT
LRM12L1X470S10APT is a single-carriage miniature guide set built around a 12 mm stainless-steel rail, 470 mm long, with the long (L) carriage fitted. Two choices define this code: the P accuracy grade for tighter travel tolerances, and the bottom-mount T format, where the rail is clamped from below so nothing protrudes above the running surface. What you receive is the assembled pair, greased with Kyodo Yushi PS No. 2.
The range's design points carry over: one rail profile shared by every LRM carriage, a ball retainer holding the recirculating balls during fitting, double-lip sealing, and covers over the screws. The balls are Japanese ISO 3290 G10 - a statement about the balls alone, not the guide assembly. Retention is a handling aid, not a promise: fit the carriage square and slowly, and use a dummy rail for repeated swaps. The guide must stay below 80 C ambient, peaking to 100 C. Load and moment ratings are not in the public data for LRM, so we will confirm them for this model through the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X470S10APT Is Used
Laser alignment carriage
Trimming the focusing lens position on a compact laser marker; the precision grade holds the beam axis steady across the travel, and bottom-mount fixing keeps the optical deck above free of screw heads.
Fibre connector polish fixture
Carrying a ferrule jig that sweeps across a polishing film in small, precise strokes at a maintenance bench, where fine control and light duty matter far more than force.
Probe station XY slide
Positioning a test probe over a die on a small semiconductor probe station, with the rail recessed into the base plate so the working plane above stays unobstructed.
Is the Airtac LRM Miniature Linear Guide LRM12L1X470S10APT the Right Guide?
When the load is heavy or overhung, step to LSH, which publishes the dynamic, static and moment figures per carriage that LRM's catalogue omits. Short travel demanding maximum rigidity points across to LGC and its crossed rollers. Before ordering this set, work the checklist: complete set, 12 mm rail, long carriage, single block on a 470 mm rail, preload A (none - the forgiving choice over ground or finish-milled surfaces), accuracy P, bottom-mount direction, and a per-model load rating we confirm together.
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 LRM12L1X470S10APT FAQ
You get a 12 mm wide, 470 mm long stainless-steel rail with one long carriage, precision grade P accuracy, preload A (none) and bottom-mount fixing. Drive M2 screws at 58.8 N.cm (steel), 39.2 N.cm (cast iron) or 29.4 N.cm (aluminium); M3 screws take 196, 127 and 98 N.cm. The ambient must not exceed 80 C, briefly 100 C. Re-grease through the rear lubrication hole every 100 km of travel or every 3 to 6 months, never mixing lubricant types. Load and moment ratings are not published for LRM - we confirm them for this model via the RFQ.
This set arrives with the carriage on the rail; leave it there unless removal is unavoidable. The ball-retention design reduces the risk, but fitting the carriage at an angle or sliding it on quickly can still drop balls, and AirTAC advises a dummy rail for repeated swaps. Do not dismantle the carriage or strike the rail - hidden damage can cost accuracy without any visible sign. On a tilted rail the carriage can slide off under its own weight, so keep a hand on it. We stock only a handful of carriage-only SKUs, so a replacement carriage is normally a special order.
