Airtac LRM Miniature Linear Guide LRM12N1X170S10CPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X170S10CPT 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 LRM12N1X170S10CPT
LRM12N1X170S10CPT is a complete AirTAC LRM miniature linear guide: one 170 mm stainless-steel rail, 12 mm wide, carrying a single standard-length recirculating-ball carriage, delivered as a factory-matched set. Because LRM uses a common-rail profile, other carriages in the LRM12 range share this same rail, but this code ships as one complete matched unit.
This configuration pairs precision (P) accuracy with medium (C) preload, the stiffest grade offered on LRM: less clearance on direction change, but more sensitivity to mounting-surface quality, so the seat should be ground or finish-milled. The carriage runs on ISO 3290 G10 Japanese balls held by a ball-retention design, and a double-lip seal plus outer cover guard the raceways. Ambient temperature must stay at or below 80 C, with peaks no higher than 100 C. Load and moment ratings are not published for LRM; we confirm them for this exact model before you order - send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X170S10CPT Is Used
Benchtop optical inspection stage
A benchtop inspection stage for PCB solder joints uses the 170 mm travel and precision P grade, with the bottom-mount rail leaving the top plate free of screw heads for cameras and fixtures.
SMT offload pick-and-place head
A small SMT offload head crossing a 12 mm rail gains steadier cornering from the medium preload C, which takes up clearance as the head reverses over the feeder bay.
Microdispensing gantry in a lab
A laboratory microdispensing gantry sitting near a curing oven is checked against the 80 C ambient limit, while the stainless rail cleans easily between runs.
Is the Airtac LRM Miniature Linear Guide LRM12N1X170S10CPT the Right Guide?
Where the load is substantial or cantilevered, step up to LSH - that series publishes dynamic, static and moment ratings per carriage, which you can size against, while LRM publishes none. If travel is short and the priority is crossed-roller rigidity, LGC is the better fit. Check before ordering: this is a complete set; rail width 12 mm; standard carriage, one on the rail; rail cut to 170 mm; preload C - medium, the rigid choice that asks more of the mounting surface; accuracy P - precision; bottom-mount fixing. Send us the load case so we can confirm the rating for this model first.
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 LRM12N1X170S10CPT FAQ
This set has a 12 mm wide rail, 170 mm long, with one standard-length carriage, a 10 mm end-hole offset, preload C (medium), precision (P) accuracy and bottom-mount fixing. Screw torque: M2 - 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 - 196 N.cm into steel, 127 into cast iron, 98 into aluminium. The ambient temperature limit is 80 C with 100 C peaks. Re-grease every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them per model, so ask before ordering.
The rail and carriage arrive factory-assembled and pre-greased, so you need only mounting screws and a ground or finish-milled seat. Either side of the rail can be the datum face. Do not strike or drop the rail - accuracy can suffer with no visible damage - and when two or more carriages share a rail, put the datum on the same side for better running accuracy.
