The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X150S10AH 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.
LRM12L1X150S10AH is a complete AirTAC LRM miniature linear guide: a 12 mm wide stainless-steel rail, 150 mm long, with one long (L) recirculating-ball carriage running on it. The set arrives assembled, rail and carriage together, so installation is a matter of bolting the rail down through its end mounting holes with M2 or M3 screws. Preload is grade A (none) and accuracy is grade H (high), with top-mount rail fixing.
What makes this configuration work is the long carriage on a short rail: a longer block engages more recirculating balls and stretches the bearing span, which steadies any tipping component on a compact axis. Inside, the balls are Japanese made to ISO 3290 G10 - a grade that applies to the balls themselves, not to the guide assembly - and a ball-retention design keeps them captive during handling. A double-lip seal scrapes lubricant and excludes dust, while an outer cover hides the screw heads and protects the seal strip. Ambient temperature must not exceed 80 C, with transient peaks to 100 C. Load and moment ratings are not published for LRM, so we confirm the figures for this exact model before you commit - send the RFQ and we will come back with them.

Rail and carriage(s) supplied together, matched as a set. If you are not sure which form you need, send us the machine or the original part number and we will confirm it before you order.
A two-axis miniature stage carrying mirror or lens mounts over a short, defined travel; the long carriage keeps the optic from rocking as it moves.
A benchtop prototype placer moving small components between tray and board; the 12 mm rail fits a tight gantry envelope.
Moving well plates between reader and stacker positions; smooth, light-duty travel suits delicate liquid-handling equipment.
Size in two directions before committing. If the load is substantial or cantilevered, step up to AirTAC LSH: that range publishes per-carriage dynamic, static and moment ratings you can calculate against, which LRM does not. If the travel is short and the priority is crossed-roller rigidity, LGC is the better fit. For this set, check the form (complete rail plus carriage), the 12 mm rail width, the long carriage, one block, the 150 mm rail length, preload A (the freest running, most forgiving of mounting imperfections), accuracy H and top-mount fixing - and confirm the load rating with us before ordering.
One practical note: across this range, rail length - not rail width - is what moves the price, so trimming travel to what the process actually needs is the cheapest lever you have.
Quick checklist
This set has a 12 mm rail width, a 150 mm rail, one long carriage, preload A (none), accuracy H (high) and top-mount rail fixing. Carriages ship pre-filled with Kyodo Yushi PS No. 2 grease; re-grease through the rear lubrication hole every 100 km of travel or every 3 to 6 months. M2 screws torque to 58.8 N.cm in steel (39.2 cast iron, 29.4 aluminium); M3 to 196 N.cm (127, 98). The ambient temperature limit is 80 C with peaks to 100 C. Load and moment ratings are not published for LRM - we confirm them per model, so ask before ordering.
Choose LRM when the envelope is miniature and the duty is light, smooth positioning - the range is built around size and running quality rather than raw capacity. Choose LSH when the load is substantial or overhung, because LSH publishes per-carriage dynamic, static and moment ratings you can size against, while LRM figures are confirmed per model. If in doubt, send us the load case with your RFQ and we will point you at the right series.
