Airtac LRM Miniature Linear Guide LRM12N1X195S10BH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X195S10BH 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 LRM12N1X195S10BH
LRM12N1X195S10BH is a complete miniature linear guide set from AirTAC: a 12 mm wide stainless steel rail, 195 mm long, with one standard-length recirculating-ball carriage running on it. End mounting holes are offset 10 mm from each rail end and the rail fixes from the top, with screws passing down through the rail into the mating surface. Rail and carriage arrive as one matched, pre-greased set.
Preload code B is the light grade - the choice when you want low rolling resistance and free-moving strokes rather than maximum rigidity. The carriage rolls on ISO 3290 G10 balls, a grade that applies to the balls themselves, held by a retention design so they stay put during handling, with a double-lip seal for grease scraping and dust exclusion and an outer cover shielding the screw line. Ambient temperature must stay at or below 80 C, with brief peaks to 100 C. One practical note: the 100 km re-grease interval is nearer than it sounds, since a 200 mm stroke cycling once a second covers that distance in roughly three weeks of continuous running. Load and moment ratings are not published for LRM - send the RFQ and we confirm the figures for this exact model.

Where the Airtac LRM Miniature Linear Guide LRM12N1X195S10BH Is Used
Micro-dispense carriage
Carrying a dispensing needle across a 195 mm stroke on a benchtop conformal-coating rig, where light preload keeps the start and finish of each bead consistent.
Optical alignment slider
Positioning a small mirror or beam-splitter mount along a photonics breadboard, where the 12 mm rail width leaves room for neighbouring optics.
Benchtop pick-and-place
Shuttling a lightweight vacuum gripper between feeder and board on a prototype SMT cell built around a single compact guide.
Is the Airtac LRM Miniature Linear Guide LRM12N1X195S10BH the Right Guide?
Size 12 is where this range actually lives: 924 of the 988 complete sets we stock are LRM12, so a 195 mm rail in common configurations ships quickly. Price tracks length, not width - stocked sets run about $66 to $831 across only two rail widths - so trim travel before you upsize. Light preload B rolls easier than medium C but tolerates less deflection; that is the usual trade-off. If the load is substantial or cantilevered, step up to LSH, which publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not. For short travel needing crossed-roller rigidity, look across at LGC. Before ordering, confirm the form, rail width, carriage length, count and rail length, preload, accuracy grade, mounting direction - and the load rating with us for this exact model.
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 LRM12N1X195S10BH FAQ
It is a complete set: 12 mm rail width, 195 mm rail length, one standard-length carriage, light preload (code B), high accuracy (code H), top-mount rail. Screw torques are M2 - 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 - 196, 127 and 98 N.cm respectively. Ambient limit is 80 C with peaks to 100 C. Carriages ship pre-filled with Kyodo Yushi PS No. 2; re-grease every 100 km of travel or every 3 to 6 months, whichever comes first. No load or moment rating is published for LRM - we confirm both for this model on request.
Choose LRM when the envelope is tight and the duty is light precision positioning - it is the small end of the range. Choose LSH when the load is substantial or overhung: LSH publishes per-carriage dynamic, static and moment ratings you can plug into a calculation, while LRM publishes none, so sizing an LRM means confirming the figure with us for the specific model. If travel is short and you need crossed-roller rigidity, LGC is the third option worth quoting.
