Airtac LRM Miniature Linear Guide LRM12N1X470S10AHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X470S10AHT 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 LRM12N1X470S10AHT
LRM12N1X470S10AHT is the bottom-mount version of AirTAC's 470 mm LRM12 set: one 12 mm wide stainless-steel rail, one standard recirculating-ball carriage, preload A, accuracy H, 10 mm end-hole offset, and a trailing T that moves the fixing screws to the underside of the rail. It arrives as an assembled rail-and-carriage set.
Bottom-mount fixing earns its place where the top face of a frame is unreachable or must stay flush - the screws sit in covered channels beneath the rail, protected by the outer cover. The rest of the LRM design package still applies: the common rail profile shared by all LRM carriages, ball retention that helps during handling, ISO 3290 G10 Japanese balls (a grade for the balls alone), and a double-lip seal for oil scraping and dust exclusion. Do not leave the carriage unheld on an inclined rail; it can slide off under its own weight. Ambient must stay at or below 80 C, peaks to 100 C. Load and moment ratings are confirmed per model - raise an RFQ and we will confirm them for this configuration.

Where the Airtac LRM Miniature Linear Guide LRM12N1X470S10AHT Is Used
Underslung vision rail in a frame
When a camera rail must hang inside a machine frame with its top face covered, bottom-mount fixing clamps the 470 mm rail from below and leaves the visible surface clean.
Panel-mounted metrology scanner
A scanner carriage travelling along a recessed panel channel cannot be bolted from above; the T suffix puts the screws underneath, where a cap rail or sheet covers them.
Compact label applicator slide
Carrying a small applicator head across a 470 mm web with the guide fixed inside an enclosed body suits bottom mounting, and the outer cover shields the seal from label dust along the run.
Is the Airtac LRM Miniature Linear Guide LRM12N1X470S10AHT the Right Guide?
Because the T suffix flips the fixing to bottom-mount, start the check there: confirm your frame lets you torque screws from underneath, and remember the lower face becomes the datum side. Then the series. A heavy or cantilevered load needs LSH, whose catalogue publishes per-carriage dynamic, static and moment ratings - numbers LRM deliberately leaves out, so we confirm capacity for this exact model instead. Short travel demanding crossed-roller rigidity points to LGC.
Finish the checklist: complete set, 12 mm rail width, standard carriage, one carriage, 470 mm rail length, preload A, accuracy H, bottom-mount direction. Torque carefully if fixing into aluminium - M2 screws take 29.4 N.cm there against 58.8 N.cm into steel - and keep the ambient under 80 C. Send the RFQ with load, moment and duty details and we will confirm the rating before you commit.
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 LRM12N1X470S10AHT FAQ
Rail width 12 mm; rail length 470 mm; one standard-length carriage; preload A (none); accuracy grade H; bottom-mount fixing with a 10 mm end-hole offset. Fastener torques: M2 at 58.8 N.cm in steel, 39.2 in cast iron, 29.4 in aluminium, and M3 at 196, 127 and 98 N.cm. Ambient temperature is capped at 80 C with transient peaks to 100 C, and lubrication is refreshed every 100 km of travel or every 3 to 6 months. What the catalogue does not publish is any load, moment, running-parallelism or speed figure for LRM; we confirm the load rating for this model when you raise an RFQ.
The trailing T switches the rail mounting from top to bottom: fixing screws pass through the rail and clamp from the underside, which suits frames where the top face is unreachable or has to stay clear. The box holds the 470 mm, 12 mm wide stainless rail with one standard carriage fitted, grade A preload, H accuracy - no separate carriage, no pairing letter, no mounting screws. Load and moment ratings are not published for LRM and are confirmed per model via RFQ. Handling tip: never leave the carriage free on an inclined rail, because it can slide off under its own weight.
