The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X195S10AH 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.
This is a complete, ready-to-mount LRM miniature guide set: one stainless-steel rail 12 mm wide and 195 mm long, drilled with a 10 mm end-hole offset for top-mount screws, with two long recirculating-ball carriages factory-fitted. It is a mechanical rolling guide for light precision duty - nothing in it moves air, so there is no bore, pressure or thrust figure to quote.
Preload A is the free-running option: the internal clearance is left in place, giving the lowest drag in the series, which suits hand-light manual stages and fast cycling - though the trade-off is that clearance rather than rigidity. The long carriages spread contact over more balls and a longer bearing span, helpful where the carried head wants to pitch. Balls are graded ISO 3290 G10 (the grade covers the balls alone, not the guide), the double-lip seal scrapes oil and shuts out dust, and the outer cover keeps larger debris away from the seal strip. Ambient temperature must stay at or below 80 C with transient peaks to 100 C - a genuine limit next to a laser module or a heated fixture. No load or moment ratings are published for LRM; we confirm the figures for this exact model via the RFQ. On cost: rail length and carriage count drive the price across this series, not the 12 mm width, and this 195 mm span sits well below the 1005 mm full length available for size 12.

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 small CO2 or fiber marking cell slides its focusing head along the workpiece; the no-preload carriage runs with minimal drag so the servo on a compact machine like this is not oversized, and the 80 C ceiling keeps the guide safe beside the laser tube.
A compact screwdriving spindle in an electronics assembly cell feeds forward to set M1 and M2 fasteners; two long carriages on one rail resist the tipping of the spindle head through the press stroke.
Rebuilding a compact engraving mill or desktop router, a maker replaces a worn slide with this 195 mm set; the long carriages and stainless rail give the light table a smoother, better-sealed axis than the original.
Rail length is what moves the price on this series, so a 195 mm span is a deliberate middle choice - long enough for a real stroke, well short of the 1005 mm full length offered in size 12. For substantial or overhung loads the right step is LSH, whose per-carriage dynamic, static and moment ratings are published and can be sized against, unlike LRM's; very short travel with crossed-roller rigidity is LGC territory. Order checklist: set form, 12 mm rail width, long carriages, two per rail, 195 mm rail length, 10 mm end offset, preload A, accuracy H, top-mount - and confirm the load rating with us before committing.
Quick checklist
Rail width 12 mm, rail length 195 mm, two long carriages, preload A (none), high (H) accuracy, top-mount rail, 10 mm end-hole offset. Mount with M3 screws at 196 N.cm into steel, 127 N.cm into cast iron or 98 N.cm into aluminium; M2 screws take 58.8, 39.2 and 29.4 N.cm. Ambient temperature must not exceed 80 C, with peaks to 100 C, and re-greasing with Kyodo Yushi PS No. 2 is due every 100 km of travel or every 3 to 6 months - a point that matters, since a 200 mm stroke cycling once a second covers that distance in about three weeks. Load, moment, parallelism and speed ratings are not published for LRM; we confirm them per model.
It is the right choice when the envelope is small and the duty is light precision positioning - two long carriages on a 12 mm rail with 195 mm of travel and no preload for the smoothest running. Step up to LSH when the load is heavy or cantilevered, because LSH publishes per-carriage dynamic, static and moment ratings you can size against, while LRM ratings are confirmed model by model through us. If the travel is very short and crossed-roller stiffness is what you need, LGC is the better match. Size 12 is the most widely listed LRM size, so a set in this configuration is among the easiest to order.
