Airtac LRM Miniature Linear Guide LRM12N1X145S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X145S10AH 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 LRM12N1X145S10AH
LRM12N1X145S10AH is a complete miniature linear guide set from AirTAC's LRM range: one standard-length ball carriage running on a 12 mm wide stainless-steel rail cut to 145 mm, top-mounted, with no preload (code A) and high accuracy (grade H). What you receive is the rail and the carriage, greased at the factory and sealed by a double-lip wiper with an outer cover over the screw line.
Size 12 is the centre of gravity of this range: 924 of the 988 LRM sets we stock are LRM12, so this configuration sits where availability is deepest and lead times are shortest. The common-rail profile means other LRM12 carriages share the same rail, which simplifies later spares. Note that the re-grease interval - every 100 km of travel or every 3 to 6 months - binds on distance sooner than expected: a 200 mm stroke cycling once per second reaches 100 km in roughly three weeks of continuous running. As with all LRM models, load and moment ratings are not published by the manufacturer; tell us your duty via the RFQ and we will confirm the figures for this set.

Where the Airtac LRM Miniature Linear Guide LRM12N1X145S10AH Is Used
PCB inspection camera axis
Second axis of a compact XY camera stage that scans populated circuit boards at a benchtop workstation, with the 145 mm rail fitting a small aluminium frame.
Suction-head slide
Guiding the suction head of a miniature pick-and-place unit placing 0402 components, where a standard-length carriage keeps the head plate compact.
Reciprocating dosing slide
Driving a pipetting head back and forth in laboratory automation; the 100 km re-grease interval arrives in weeks on a fast short stroke, so plan access to the lubrication hole.
Is the Airtac LRM Miniature Linear Guide LRM12N1X145S10AH the Right Guide?
Because 12 mm is the heavily stocked LRM size, this set is the safe pick when the schedule matters - a design laid out around LRM12 usually ships faster than one held on LRM15, which we do not stock in depth. If the load is substantial or cantilevered, move up to LSH, which publishes dynamic, static and moment ratings per carriage that you can size against; LRM offers no published figures to calculate from. For a short travel needing crossed-roller rigidity, compare LGC.
Before ordering, confirm: complete set form, 12 mm rail width, standard carriage length, one carriage, 145 mm rail, preload A (none - simplest to mount, but the least resistance to an overturning load), accuracy H, top-mount rail, and confirm the load rating with us first.
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 LRM12N1X145S10AH FAQ
Rail width 12 mm, rail length 145 mm, one standard-length carriage, top-mount rail, preload A (none), accuracy H (high). Screw torque: M2 screws 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 screws 196, 127 and 98 N.cm. Ambient limit 80 C, transient peaks to 100 C. Lubrication: factory-filled, top up every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for this series - we confirm them for the specific model on request.
You receive the complete set: one 145 mm stainless-steel rail, 12 mm wide, with one standard carriage pre-fitted and pre-greased. No mounting screws, end brackets or limit switches are part of the delivery, and there is no second carriage - the code specifies one. Rail mounting is top-mount, so the fixings sit in the rail root and you bolt down from above. If you ever need a replacement carriage alone, note that our carriage-only stock is very thin (four SKUs), so plan ahead or keep a spare set.
