Airtac LRM Miniature Linear Guide LRM12N1X170S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X170S10CP 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 LRM12N1X170S10CP
This is the stiffest, most tightly graded version of the 170 mm size-12 set: LRM12N1X170S10CP runs a single standard-length carriage on a 12 mm stainless rail with medium preload (code C) and precision accuracy (code P), fixed from the top. Medium preload puts the balls under real interference, so the carriage resists rocking and play along the travel.
The trade-offs are deliberate. Preload C is the least forgiving grade to install: it wants a flat, ground or finish-milled seat and clean, evenly torqued screws, and it runs with slightly more drag than grades A or B. Grade P tightens travel accuracy for measurement and alignment work. The running balls are ISO 3290 G10 Japanese grade, a double-lip seal and outer cover protect the raceways, and the common-rail profile means any LRM12 carriage fits this rail. Keep the ambient at or below 80 C, with peaks to 100 C. AirTAC publishes no load or moment figures for LRM, so capacity is confirmed model by model - raise an RFQ and we will return the confirmed numbers for this part.

Where the Airtac LRM Miniature Linear Guide LRM12N1X170S10CP Is Used
Gauge fixture clamp slide
In a metrology fixture, a clamped gauge or workpiece slides into the measuring position; medium preload keeps the clamp station from shifting while the operator works on it.
Custom metrology XY stage build
Machine builders assembling a compact measuring stage pick the P grade for its tighter travel accuracy, pairing the 12 mm rail with a precision carriage under a probe or camera.
Parcel dimensioning scanner
A scanning head measuring small parcels on a sortation line traverses a fixed 170 mm path; grade P keeps the sensor alignment stable, and the seals handle corridor dust.
Is the Airtac LRM Miniature Linear Guide LRM12N1X170S10CP the Right Guide?
Check the duty before choosing this grade. Medium preload and P accuracy pay off in metrology and fine positioning; for a free-running slide moving light parts, preload A costs less and glides easier. Size 12 is the most widely held LRM size in our range, so availability is strongest here - a layout around a 12 mm rail is the practical choice. If the load is genuinely substantial or overhung, step to AirTAC LSH, which publishes dynamic, static and moment ratings per carriage so you can calculate margins; LRM offers no such table. For short strokes needing crossed-roller stiffness, LGC is the cross-over pick. Then work the checklist: set or carriage only, 12 mm width, standard block, count of one, 170 mm rail, preload C, grade P, top-mount fixing - and confirm the load rating for this model with us before committing.
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 LRM12N1X170S10CP FAQ
Rail width 12 mm; rail length 170 mm with a 10 mm end-hole offset; one standard-length carriage; medium preload (C); precision accuracy (P); top-mount mounting. Screw torque: M3 at 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium. Maximum ambient temperature is 80 C with transient peaks to 100 C; re-grease every 100 km of travel or every 3 to 6 months. LRM has no published load, moment, parallelism or speed ratings - we confirm the load figures for this specific model on request.
Choose this set when the envelope is tight and the load is light: a 12 mm rail and a single compact carriage give precise, smooth travel in a small footprint, and the P grade plus medium preload deliver tight, play-free motion. Choose LSH when you need a published rating table - dynamic, static and moment loads per carriage - to prove the margin; LRM offers no such table and each model's capacity is confirmed with us. For very short travel with high rigidity demands, also price LGC crossed-roller guides.
