Airtac LRM Miniature Linear Guide LRM12L2X470S10BPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X470S10BPT is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriages. 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 LRM12L2X470S10BPT
LRM12L2X470S10BPT combines the two premium choices in one 12 mm code: accuracy grade P for tight tracking along the stroke, and a bottom-mount (T) rail that clamps from beneath so the top face stays clear of fasteners. The set is one 470 mm stainless-steel rail, 12 mm wide, with two long carriages, preload B, and a 10 mm end offset. Two carriages spaced along the travel are what resist tipping along the direction of motion - the load sits between them rather than hanging off a single block - and the long bodies add bearing span on top of that.
Handle the assembly with care: on an inclined rail a carriage can slide off under its own weight, and although ball retention holds the ISO 3290 G10 balls (a grade for the balls only) in place, careless insertion can still shed them. The double-lip seal manages lubrication and dust, the outer cover shields it, and the common-rail profile lets other LRM12 carriages share the same rail. Ambient temperature must stay at or below 80 C, peaking at 100 C briefly. Load and moment ratings are not published for the series; we confirm them per model - ask through the RFQ before ordering.

Where the Airtac LRM Miniature Linear Guide LRM12L2X470S10BPT Is Used
OLED panel transfer stage
A slim transfer section in flat-panel handling where the glass rides above the rail and no protruding screw heads may mark or shadow the panel.
Optical bench camera rail
A machine-vision camera sliding along an optical breadboard for focus sweeps, guided beneath the mounting plate so the working surface stays clean.
Retrofit for a small CNC gantry
Replacing a worn round-shaft slide on a compact router retrofit, where the flat stainless rail bolts into a machined channel under the carriage plate.
Is the Airtac LRM Miniature Linear Guide LRM12L2X470S10BPT the Right Guide?
This is a specification where every line of the checklist matters, because two of them cost money: accuracy P, and the machined pocket your base needs for bottom fixing. Verify the form (complete set, rail included), rail width 12 mm, long carriages, count of two, 470 mm rail length, preload B (light - smooth running with clearance mostly removed, but not the stiffest option; C exists if you want firmer), accuracy P, bottom-mount direction. If the load is anything beyond light, or it cantilevers, switch to LSH - it publishes dynamic, static and moment ratings per carriage that you can actually size against, which LRM does not, so we confirm LRM loads per model. Short travel needing crossed-roller rigidity points to LGC. Confirm the load rating with us first, whatever you choose.
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 LRM12L2X470S10BPT FAQ
Yes: 12 mm stainless-steel rail, 470 mm long, two long (L) carriages, 10 mm end-hole offset, preload B (light), accuracy P, bottom-mount rail. Screw torques: M3 - 196 N.cm steel, 127 N.cm cast iron, 98 N.cm aluminium; M2 - 58.8, 39.2 and 29.4 N.cm. Ambient limit 80 C with 100 C peaks; re-grease every 100 km of travel or every 3 to 6 months, with grease quantities varying per model. Load and moment ratings are not published for LRM; we confirm them for this exact SKU before any order.
A complete set: the 470 mm rail and both long carriages, assembled and preloaded - there is no separate carriage to pair. Because the rail is bottom-mount, plan the counterbores and tapped holes in your base first, and grind or finish-mill both mating surfaces for the rated travel accuracy. Keep the carriage square when fitting or removing it - the ball retainer helps, but angled or hurried handling drops balls, and a dummy rail makes swaps safe. Our carriage-only stock is very thin, so treat any future carriage replacement as a special order.
