Airtac LRM Miniature Linear Guide LRM12N2X195S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X195S10AP 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.

About the Airtac LRM Miniature Linear Guide LRM12N2X195S10AP
LRM12N2X195S10AP is a complete AirTAC LRM miniature guide set. In the box is a single 195 mm stainless-steel rail, 12 mm wide, with two standard-length recirculating-ball carriages already fitted - nothing to assemble before bolting down. The final letters decode as precision (P) accuracy with preload code A, which means no preload, and the rail is drilled for top mounting.
AirTAC gives the range a common rail, so any LRM12 carriage will mount on this same profile if you extend the system later. The carriages run on Japanese-made balls graded ISO 3290 G10 - a specification for the balls only - held by a retainer so they stay put during handling. A double-lip seal scrapes lubricant back and keeps contamination out, and the outer cover protects the seal strip from larger debris while concealing the screws. The published environmental limit is 80 C ambient, with transients to 100 C, so site the axis away from hot surfaces. Load and moment ratings are not published for this series; we confirm the figures for this exact model when you send an RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X195S10AP Is Used
Vision inspection stage
A camera carriage on a benchtop optical inspection rig: the P accuracy grade and two bearing points keep the sensor path repeatable over the 195 mm rail.
SMT pick-and-place head
Light pick-and-place heads in small electronics assembly cells suit this 12 mm set; two standard carriages spread a light load and resist tipping along the stroke.
Compact XY positioning stage
Building a two-axis miniature stage, 195 mm ships as one piece, so there is no spliced-joint alignment to worry about on either axis.
Is the Airtac LRM Miniature Linear Guide LRM12N2X195S10AP the Right Guide?
Size the axis in two directions. If the load is substantial or cantilevers off the carriage, step up to AirTAC LSH, which publishes per-carriage dynamic, static and moment ratings you can calculate against - LRM offers no such table, so an LSH design is verifiable on paper. If the travel is short and the priority is crossed-roller rigidity, LGC is the better fit. For this set, work the checklist: complete-set form, 12 mm rail width, standard carriage length, two carriages, 195 mm rail, preload A (the freest-running, least stiff choice), accuracy P, top-mount direction, and a load rating confirmed with us before you commit.
Two buying notes: size 12 is the deepest-stocked LRM width (924 of 988 stocked sets), so lead times here are short; and since stocked prices run about $66 to $831 across only two rail widths, it is rail length and carriage count - not width - that drives the cost.
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 LRM12N2X195S10AP FAQ
Rail width 12 mm, rail length 195 mm, two standard-length carriages, no preload (A), precision accuracy (P), top-mount rail. M2 screws torque to 58.8 N.cm in steel, 39.2 in cast iron, 29.4 in aluminium; M3 to 196, 127 and 98 N.cm. Ambient temperature must not exceed 80 C, with peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months; carriages arrive filled with Kyodo Yushi PS No. 2. AirTAC publishes no load or moment ratings for LRM, so we confirm them per model via RFQ before you order.
Use LRM where the envelope and duty are light, as here: a 12 mm stainless rail with two standard blocks at precision grade. Move to LSH when the load is heavy or overhung, because LSH publishes dynamic, static and moment ratings per carriage that you can plug into a calculation - LRM publishes none of these. With LRM, send us the load, moment and duty details by RFQ and we confirm the rating for the exact model before you commit.
