Airtac LRM Miniature Linear Guide LRM12L1X445S10APT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X445S10APT 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 LRM12L1X445S10APT
LRM12L1X445S10APT is a complete AirTAC LRM miniature linear guide set: one 12 mm wide stainless-steel rail, 445 mm long, with a single long carriage running on it. The long body spreads the recirculating balls over a greater footprint than the standard carriage, and the set arrives factory-filled with Kyodo Yushi PS No. 2 grease.
The trailing T in the code means a bottom-mount rail, so it bolts up from underneath - useful when the top face of your table has to stay clear for the workpiece or the optics. This is a precision-grade (P) set with no preload (A), so it runs as freely as the series allows. The carriage uses Japanese balls graded ISO 3290 G10 - that grade applies to the balls only - inside a double-lip seal under an outer cover that shields the screws and seal strip. Ambient temperature must stay at or below 80 C, with brief peaks no higher than 100 C. Basic dynamic and static load ratings and moment figures are not published for LRM; we confirm the figures for this exact model when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X445S10APT Is Used
Compact XY inspection stage
A benchtop microscope stage where the underside is the only accessible mounting face; the bottom-mount rail fixes from below and the long carriage keeps the stage plate level as it travels.
Semiconductor handler slide
A die-orienting slide in a small component handler, where a precision-grade 12 mm rail gives repeatable positioning in a tight envelope without overshadowing the rest of the mechanism.
Optics lab alignment slide
A manual alignment slide carrying a lens holder or beam-fold mirror, where free-rolling no-preload motion and a precision rail let an operator set position with a light touch.
Is the Airtac LRM Miniature Linear Guide LRM12L1X445S10APT the Right Guide?
If the load is substantial or overhung, step up to the LSH series instead: LSH publishes per-carriage dynamic, static and moment ratings you can actually size against, which LRM does not, and LRM is aimed at light-duty positioning. Where travel is short but you need crossed-roller rigidity, LGC is the better match. Before committing, run this checklist against your layout: form (complete set, not a carriage), 12 mm rail width, long carriage, one block, 445 mm rail, preload A - the easiest rolling but any play must be taken up elsewhere in the design - accuracy P, bottom-mount fixing, and a confirmed load rating from us, since no LRM figure is published. If you may need a spare carriage later, keep the pairing code from the original.
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 LRM12L1X445S10APT FAQ
Rail width 12 mm; rail length 445 mm; one long carriage; preload A (none); accuracy P (precision); bottom-mount rail. Screw torque for fixing: M2 screws 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 screws 196, 127 and 98 N.cm respectively. Ambient temperature must not exceed 80 C, with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months, topping up through the rear lubrication hole with Kyodo Yushi PS No. 2. Basic dynamic load, static load and moment ratings are not published for LRM; we confirm them per model before you order.
Yes - the X in the code marks a complete set: one 445 mm stainless-steel rail plus one long carriage already fitted to it, greased at the factory. Nothing else is included, and there is no rail-only or carriage-only content in this SKU. If you later want a replacement carriage on its own, note that very few carriage-only LRM part numbers are listed, so most spares are ordered to match the pairing code of your original set.
