Airtac LRM Miniature Linear Guide LRM12N1X195S10CHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X195S10CHT 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 LRM12N1X195S10CHT
LRM12N1X195S10CHT is the bottom-mount version of this AirTAC LRM complete set: a stainless-steel rail 195 mm long and 12 mm wide with one standard-length recirculating-ball carriage, medium preload (C) and high accuracy grade (H). The trailing T in the code is what matters to your drawing - the fixing holes are arranged so the rail bolts down from beneath, into a base you cannot reach from above.
Because the screws sit under the rail, plan the counterbore depth and access before cutting the base plate, and have the mating surface ground or finish-milled so the high accuracy grade shows up in travel. The ball-retention design keeps the balls captive during normal handling, but the manufacturer is clear that inserting the carriage at an angle or swapping it hastily can still drop balls - on a bottom-mount installation, where access is awkward by definition, work slowly or use a dummy rail. The carriage runs on Japanese-made ISO 3290 G10 balls (a ball-grade specification only, not a standard for the assembly) behind a double-lip seal and outer cover. Keep ambient temperature at or below 80 C, peaks to 100 C. No load or moment rating is published for LRM; we confirm the figures for this model on request - send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X195S10CHT Is Used
Inverted microscope focus slide
On an optical bench where the top face must stay clear for samples, a bottom-mount rail is fixed from beneath, leaving an uninterrupted working surface above.
PCB test fixture slide
A fixture pressing boards into edge connectors cycles all day; medium preload resists play while the double-lip seal keeps flux dust out of the raceway.
Compact dispensing valve carrier
Mounting a small glue or solder-paste dispenser on a 12 mm rail keeps the head light; the 195 mm stroke clears a strip of boards in one pass.
Is the Airtac LRM Miniature Linear Guide LRM12N1X195S10CHT the Right Guide?
Pick bottom-mount only when the machine design forces it: an enclosed base, a top face that must stay clear, or a cover over the rail. Everything else follows the same checklist - form (complete set), rail width 12 mm, standard carriage, one block, 195 mm rail length, preload C, accuracy H, mounting direction, and the code off the old part if this is a replacement. Note that size 12 is by far the deepest stocked LRM size, so availability is strong here. For heavy or overhung loads, move to AirTAC LSH, which publishes dynamic, static and moment ratings per carriage - LRM does not, so those numbers cannot be quoted. For short travel needing crossed-roller rigidity, compare LGC. Either way, confirm the load rating for this exact model with us before ordering.
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 LRM12N1X195S10CHT FAQ
The set is a 12 mm wide stainless rail, 195 mm long, one standard carriage, medium preload (C), high accuracy (H), bottom-mount holes, 10 mm end-hole offset. M3 screws torque to 196 N.cm in steel, 127 N.cm in cast iron and 98 N.cm in aluminium. Do not exceed 80 C ambient, with 100 C as the transient peak. Factory grease is Kyodo Yushi PS No. 2, topped up via the rear lubrication hole every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM, so capacity is confirmed per model - contact us before you commit.
The box holds one complete matched set: a 195 mm stainless rail and one pre-fitted standard carriage with medium preload and high accuracy. Nothing else is needed, but the T in the code means the rail is fixed from below - screws go up through the base plate into the rail's underside holes, so design the counterbores and access first. The mounting surface should be ground or finish-milled for the rated travel accuracy. If you ever remove the carriage, keep it on the rail unless necessary; angled refitting can drop balls.
