Airtac LRM Miniature Linear Guide LRM12N2X470S10BH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X470S10BH 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 LRM12N2X470S10BH
LRM12N2X470S10BH is a complete miniature linear guide set from AirTAC's LRM line. In the box: a single 470 mm stainless-steel rail 12 mm wide, with two standard-length recirculating-ball carriages mounted, top-mount fixing, 10 mm end-hole offset, high accuracy grade H, and preload code B - the light preload grade.
Light preload is the middle choice on LRM: it takes the float out of the carriage so the axis feels firmer under small reversing loads, at the cost of slightly more running drag than a preload-A set. Because long and standard carriages are stocked in near-equal depth, choosing the standard block here is purely a geometry decision, not an availability one. The design package is the same across the series - common-rail profile, ball retention (with the caveat that angled or hurried carriage fitting can still shed balls), Japanese ISO 3290 G10 balls in the recirculating circuit only, double-lip seals, and outer covers over the screws. Ambient temperature is limited to 80 C with transient peaks of 100 C. Mind the re-grease clock: a 200 mm stroke cycling once per second covers 100 km in roughly three weeks of continuous running, so the distance interval can bind well before the 3 to 6 month calendar one. Load and moment ratings are not published for LRM; we will confirm them for this exact model - just raise the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X470S10BH Is Used
Automated screwdriving station
A benchtop screwdriving head reverses direction at every fastener; light preload B removes the lash that would otherwise let the bit wander at each reversal.
Laser autofocus stage
A compact autofocus slide for a cutting laser wants firm, repeatable motion near the optics; the 80 C ambient cap and double-lip seals suit the warm, dusty head zone.
Sample-handling mini gantry
A two-axis sample handler in a lab analyzer uses paired rails; mounting both datum faces on the same side of each rail keeps running accuracy consistent across the pair.
Is the Airtac LRM Miniature Linear Guide LRM12N2X470S10BH the Right Guide?
Think in this order: if the carried mass is significant or overhung, go up to LSH, whose published dynamic, static and moment ratings per carriage let you verify the case numerically - LRM offers no such table. If the travel is short and you need crossed-roller stiffness, cross to LGC. For this set itself, confirm: complete-set form, 12 mm rail width, standard carriage length, two carriages on a 470 mm rail, preload B with its drag-versus-rigidity trade-off, accuracy H (the cost-saving grade against P), top-mount rail, and a load rating confirmed with us for this model. If your machine frame is loosely toleranced, H accuracy matched to a finish-milled or ground mounting surface is the realistic pairing.
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 LRM12N2X470S10BH FAQ
Complete set: 12 mm wide stainless rail, 470 mm long, two standard-length carriages, 10 mm end offset, preload code B (light), accuracy grade H, top-mount fixing. Fixing torque for M3 screws is 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium; for M2 screws, 58.8 / 39.2 / 29.4 N.cm. Ambient limit is 80 C with transient peaks to 100 C. Carriages ship with Kyodo Yushi PS No. 2 grease; re-grease after every 100 km of travel or every 3 to 6 months, whichever comes first. Dynamic load, static load and moment ratings are not published for LRM - we confirm those per model.
Preload B is worth it when the axis reverses often and you want firm motion without the running drag of a heavier fit - on LRM, light is as far as the preload range goes. For servicing, keep the carriage on the rail unless you must remove it: the ball-retention design helps, but a hasty or angled refit can still drop balls, and a dummy rail makes safe carriage swaps far easier. Note that only a handful of carriage-only spares are stocked, so a replacement carriage is usually a special order - and the load ratings, again, are confirmed per model rather than published.
