Airtac LRM Miniature Linear Guide LRM12N1X395S10BHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X395S10BHT 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 LRM12N1X395S10BHT
This AirTAC LRM12N1X395S10BHT is a complete miniature linear guide set: one 395 mm stainless-steel rail, 12 mm wide, carrying a single standard-length recirculating-ball carriage. The trailing T in the code matters at the bench - the rail is drilled for bottom-mounting, so the fixing screws are reached from underneath the rail rather than through the top. Everything you need for one axis of travel is in the box; there is no second carriage and no rail splicing to do.
The LRM design uses a common rail profile so different carriages share the same rail, and a ball-retention feature that stops the balls spilling out during normal handling - though the manufacturer is clear that inserting the carriage at an angle or swapping it quickly can still drop balls, so keep a dummy rail on hand if you expect field replacements. The balls themselves are ISO 3290 G10 grade, Japanese made, chosen for roundness and wear, and the carriage carries a double-lip seal with an outer cover to exclude dust. Ambient temperature must stay below 80 C, with brief peaks to 100 C. A light preload (code B) removes most of the play without the stick-slip stiffness of a heavier grade - a fair middle setting for a 395 mm axis. Where a datasheet would normally list load and moment ratings, this series publishes none: the figure for your exact model is confirmed on request before you order, so send us the RFQ and we will size it with you.

Where the Airtac LRM Miniature Linear Guide LRM12N1X395S10BHT Is Used
Optical inspection microscope stage
A 395 mm travel axis carries a camera or sensor head over sample trays on an inspection bench, where the 12 mm rail width keeps the stage frame slim and the light preload keeps positioning repeatable.
Laser alignment slide in a marking cell
Bottom-mount fixing suits an enclosed beam path where the top face of the rail must stay clean and unobstructed; the standard carriage gives a compact bearing footprint for the mirror or lens holder.
Small pick-and-place head on a benchtop robot
A single-carriage 12 mm axis moves a lightweight gripper between component feeders; the ball-retention design survives routine handling and the 80 C ambient ceiling fits most electronics workcells.
Is the Airtac LRM Miniature Linear Guide LRM12N1X395S10BHT the Right Guide?
Start by asking whether a 12 mm miniature guide is genuinely the right class. If the load is substantial or cantilevered off the carriage, step up to the AirTAC LSH series instead - LSH publishes per-carriage dynamic, static and moment ratings you can actually calculate against, which LRM does not. If the travel is short and the priority is crossed-roller rigidity in a tight footprint, the LGC series is the better cross-check. Before committing to this set, work the checklist: complete set or carriage only, rail width, carriage length, carriage count, rail length, preload grade (B here means light - note that lighter preload installs easier but allows a little more play), H versus P accuracy, and bottom-mount versus top-mount rail. Then confirm the load rating with us for this exact configuration - that last step is the one that prevents an expensive mis-specification.
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 LRM12N1X395S10BHT FAQ
This is a complete set: one standard-length carriage on a single 395 mm rail, 12 mm rail width, bottom-mount rail fixing (screws from below), light preload (code B) and H high accuracy. M3 fixing screws torque to 196 N.cm into steel, 127 N.cm into cast iron and 98 N.cm into aluminium. The ambient temperature limit is 80 C with transient peaks to 100 C, and re-greasing is due every 100 km of travel or every 3 to 6 months, whichever comes first. Basic dynamic load rating, static load rating and moment ratings are not published for the LRM series - we confirm the figures for this exact model before you order.
The trailing T in the ordering code means the mounting holes are tapped for fixing from underneath the rail. You bolt the guide to the machine from below, which keeps the top face free - useful where covers, guards or moving parts sit above the rail. The mounting surface still needs to be ground or finish-milled to hold the rated travel accuracy, and either long edge of the rail can serve as the datum face. Note that carriage-only replacements for this set are mostly special orders, since our carriage-only range is very thin - plan any field swap with a dummy rail and ask us about availability early.
