Airtac LRM Miniature Linear Guide LRM12N1X470S10BH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X470S10BH 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 LRM12N1X470S10BH
LRM12N1X470S10BH is a complete set built around preload grade B: one standard LRM12 carriage running on a 470 mm stainless rail, 12 mm wide, arranged for top mounting. Light preload tensions the balls slightly, taking up clearance so the carriage feels firmer than a grade A set while still rolling easily by hand.
The trade-off deserves stating plainly: preload B reduces play but adds a touch of running resistance and is less forgiving of imperfect mounting surfaces than the unloaded grade. Accuracy grade H suits positioning work that does not demand precision-grade straightness. The rolling elements are ISO 3290 G10 balls - that specification applies to the balls themselves - protected by a double-lip seal and an outer cover. AirTAC publishes no load or moment ratings for LRM, so the capacity question is settled per model: ask us with your RFQ and we confirm the figure before you commit.

Where the Airtac LRM Miniature Linear Guide LRM12N1X470S10BH Is Used
Wire-feed pick-and-place head
A small gripper shuttles between a wire feeder and a crimp station; light preload keeps the head from rocking at each indexing stop.
Laboratory dosing axis
A pipetting head tracks along a microplate row, where grade H accuracy and a play-free stroke keep tip placement consistent well to well.
Benchtop engraver slide
Guiding a compact spindle over small nameplates on a workshop bench, with the 100 km re-grease interval setting a service rhythm that fits light daily use.
Is the Airtac LRM Miniature Linear Guide LRM12N1X470S10BH the Right Guide?
Choose this set when you want the middle of the LRM preload range on a size 12 rail. If the load is heavy or overhung, move up to LSH, whose catalogue gives per-carriage dynamic, static and moment ratings you can design against - LRM offers no such table. If the travel is short and stiffness matters more than reach, LGC with crossed rollers is the stronger cross-series option. Checklist for this code: complete set, 12 mm rail width, standard carriage, one carriage, 470 mm length, preload B (light - firmer feel, slight drag), accuracy H, top-mount, and a load rating confirmed with us in writing first.

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 LRM12N1X470S10BH FAQ
Rail 12 mm wide and 470 mm long, one standard carriage, preload grade B (light), accuracy grade H, top-mount rail. Mounting screws: M2 takes 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 takes 196, 127 and 98 N.cm in the same order. Ambient temperature must not exceed 80 C, peaking at 100 C briefly. Grease is Kyodo Yushi PS No. 2 from the factory, topped up every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM; we confirm them per model via RFQ.
A matched pair: the 470 mm rail and its single standard carriage, pre-greased, with no fasteners and no mounting plate included. One practical heads-up: even with the ball-retention design, fitting the carriage at an angle can drop balls, so slide it on square - and if you plan repeated carriage swaps, budget for a dummy rail, because carriage-only LRM parts are a special order here with only four SKUs kept on the shelf.
