Airtac LRM Miniature Linear Guide LRM12L2X170S10BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X170S10BP 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 LRM12L2X170S10BP
This SKU is a complete assembled set from AirTAC's LRM miniature guide series: one stainless-steel rail 12 mm wide and 170 mm long, drilled with a 10 mm end-hole offset for top-mount fixing, carrying two long recirculating-ball carriages that arrive already running on the rail. It is a mechanical rolling guide for light-duty precision positioning, not a pneumatic part - no bore, no air, no stroke in the cylinder sense.
Precision (P) accuracy combined with light (B) preload is the pairing to choose when straight, free-running travel matters more than maximum rigidity, and the long carriage spreads the load over more balls and a longer bearing span, which helps any tipping component. The carriages run on balls graded ISO 3290 G10 (the grade applies to the balls only, not the assembly), protected by a double-lip seal for oil scraping and dust exclusion beneath an outer cover that hides the screws and keeps out larger debris. Keep the ambient temperature at or below 80 C, with transient peaks no higher than 100 C. AirTAC publishes no load or moment ratings for LRM, so the figures for this exact model are confirmed per model - send us the RFQ. Worth knowing: long carriages are supplied as widely as standard ones in this range, so specifying the L body costs nothing in sourcing.

Where the Airtac LRM Miniature Linear Guide LRM12L2X170S10BP Is Used
PCB inspection XY stage
A benchtop printed-circuit-board metrology machine moves its camera between test points on two of these guides; the P accuracy grade and free-running light preload keep the travel repeatable across a 170 mm span.
Laboratory optics slider
On a photonics bench, a detector or lens holder rides a single long carriage so the researcher can translate a component along the optical axis without disturbing its alignment.
Vision camera glide rail
A small parts-inspection fixture slides its camera head over a tray of components; the long block resists the pitching of the camera as it stops and starts at each inspection position.
Is the Airtac LRM Miniature Linear Guide LRM12L2X170S10BP the Right Guide?
Choose this code when you want the smooth side of precision: light preload paired with the P accuracy grade for measuring-type motion on a compact stage. If the load is substantial or hangs on a cantilever, step up to AirTAC LSH instead - LSH publishes per-carriage dynamic, static and moment ratings you can size against, while LRM's are confirmed model by model through us. For very short travel where crossed-roller rigidity matters, LGC is the right cross-over. Order checklist: set form, 12 mm rail width, long carriages, two per rail, 170 mm rail length, 10 mm end offset, preload B, accuracy P, top-mount - and confirm the load rating 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 LRM12L2X170S10BP FAQ
Rail width 12 mm, rail length 170 mm, two long carriages, light (B) preload, precision (P) accuracy, top-mount rail, 10 mm end-hole offset. Mount with M3 screws at 196 N.cm into steel, 127 N.cm into cast iron or 98 N.cm into aluminium; M2 screws take 58.8, 39.2 and 29.4 N.cm respectively. Ambient temperature must stay at or below 80 C, with peaks to 100 C, and the carriages should be re-greased with Kyodo Yushi PS No. 2 every 100 km of travel or every 3 to 6 months. AirTAC publishes no load, moment, running-parallelism or speed ratings for LRM - we confirm those per model on request.
Pick LRM when the envelope is small and the duty is light precision positioning, as here: a 12 mm rail, two long carriages and 170 mm of travel in a low-profile package. Choose LSH when the load is heavy or overhung, because LSH has published per-carriage dynamic, static and moment ratings to size from, whereas LRM ratings are confirmed model by model through us. If the travel is very short and you need crossed-roller stiffness, LGC is the third option. Size 12 is the backbone of the LRM range, so a configuration like this is the easiest in the series to source.
