The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X195S10AH 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.
LRM12N2X195S10AH is the full-set form of the AirTAC LRM range: one 195 mm stainless rail, 12 mm across, with two standard-length ball carriages supplied already mounted. The S10 offset leaves 10 mm between the rail end and the first hole, giving room for screw heads and tool access right at the stroke limits.
An installation detail that pays off with this configuration: with more than one carriage on a rail, set the datum face on the same side for both so running accuracy stays consistent across the stroke. LRM uses a common-rail profile so carriage types share one rail shape, retains its Japanese ISO 3290 G10 balls so they do not spill during handling, and seals each carriage with a double lip beneath an outer cover. Ambient heat is capped at 80 C with 100 C transient peaks allowed briefly. This family's load and moment figures are confirmed per model rather than published - include the load case in your RFQ and we reply with the numbers for this exact set.

Specifications follow the official AirTAC LRM catalogue. The catalogue does not publish load or moment ratings, running parallelism, speed limits, or carriage base material for LRM. We will not quote a figure we cannot source — ask us and we will confirm it for your model.

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 bench fixture that seats delicate board connectors indexes under a 12 mm rail; setting the datum on one side for both carriages keeps the press head square to the board through every stroke.
A workshop measuring microscope carries samples on a sliding plate; the 195 mm rail gives enough span for the sample holder and the counter-run of the carriage pair on one rail.
A wafer-handling tray step-feeder advances pockets one station at a time on short 12 mm guides, where the outer cover keeps packing debris away from the seal strips.
Before ordering, size the alternatives too. LSH suits substantial or cantilevered loads because its ratings table gives dynamic, static and moment figures per carriage; LRM offers no published table to size against. LGC covers short-travel work where crossed-roller rigidity matters more than stroke length. Match this model against your layout: it is a complete set, 12 mm rail width, standard carriages, two of them, 195 mm rail, preload A which runs free and tolerates mounting imperfections best, high accuracy H, top-mount rail, no pairing code. Note also that size 12 is by far the deepest stocked width - 924 of 988 stocked LRM sets - so availability here is the best in the range. Send the load case with the RFQ and we confirm the rating for this set.
Quick checklist
Specification highlights: 12 mm rail width, 195 mm rail length, two standard carriages, no preload (grade A), high accuracy (grade H), top-mount rail, first hole 10 mm from each end. Installation torque: M2 screws 58.8 N.cm into steel, 39.2 N.cm into cast iron, 29.4 N.cm into aluminium; M3 screws 196, 127 and 98 N.cm. Keep ambient temperature at or below 80 C (transient peaks 100 C) and re-grease after every 100 km of travel or every 3 to 6 months, whichever comes first. Load and moment ratings are not published for LRM - we confirm them for this exact set before ordering.
The LRM12N2X195S10AH ordering code describes the complete assembled guide: one 195 mm stainless-steel rail with both standard carriages mounted and factory-lubricated with Kyodo Yushi PS No. 2. It is not a carriage-only order and needs no pairing code. If you later want a spare carriage, remember carriage-only SKUs are thin on the ground - only a handful are stocked - so plan on a special order, and refit carriages carefully or use a dummy rail so balls are not dropped.
