Airtac LRM Miniature Linear Guide LRM12N1X295S10BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X295S10BP 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 LRM12N1X295S10BP
LRM12N1X295S10BP is a complete miniature linear guide set from AirTAC: a 12 mm wide stainless-steel rail, cut to 295 mm, carrying a single standard-length recirculating-ball carriage. The S10 segment places the end fixing holes 10 mm in from each rail end, and the blank mounting code means the rail bolts down from the top. Everything ships as one pre-greased assembly, ready to fix to a ground or finish-milled surface.
This set carries a light preload (code B), which keeps travel smooth and low in drag while still removing play - a good fit for small positioning axes where feel matters more than outright stiffness. The recirculating balls inside the carriage are Japanese-made ISO 3290 G10 grade, chosen for roundness, and a double-lip seal works against the rail to hold grease in and push dust out, while an outer cover shields the seal strip from larger debris. Ball retention keeps the balls captive during handling, though the maker still warns against angling the carriage onto the rail or swapping it hastily. Keep the ambient temperature at or below 80 C, with brief peaks to 100 C. Load and moment ratings are not published for the LRM range; tell us your application and we confirm the figures for this exact model before you order.

Where the Airtac LRM Miniature Linear Guide LRM12N1X295S10BP Is Used
Optics alignment stage
A 295 mm axis under a bench-top optical alignment jig, where the light preload keeps hand-adjusted positioning smooth and free of stick-slip on a 12 mm rail.
Microplate sampling head
Guiding a sampling head across a microplate in a small laboratory analyzer, where the miniature envelope leaves room for tubing and sensors on the deck.
Connector test fixture
Carrying a probe block along a ribbon-cable connector during continuity testing in an electronics workshop, with a single-carriage layout keeping the fixture compact.
Is the Airtac LRM Miniature Linear Guide LRM12N1X295S10BP the Right Guide?
If the load is substantial or sits on a cantilever, step up to LSH instead: it publishes per-carriage dynamic, static and moment ratings you can actually size against, which LRM does not. For short travel that needs crossed-roller rigidity, compare LGC. To lock in this SKU, run the checklist: complete set (not a carriage alone), 12 mm rail width, standard carriage length, one carriage, 295 mm rail, preload B - smooth and low-drag rather than rigid - accuracy H, top-mount fixing, and confirmation of the load rating with us before you commit.
A cost note worth knowing before you finalise travel: stocked LRM sets span roughly $66 to $831 across only two rail widths, and nearly all of that spread comes from rail length and carriage count, so trimming the 295 mm travel is the fastest route to a lower price.
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 LRM12N1X295S10BP FAQ
This set uses a rail 12 mm wide and 295 mm long, with the end holes offset 10 mm from each end. It carries one standard-length carriage, preloaded to grade B (light) and made to accuracy grade H (high), and the rail fixes from the top. Recommended screw torque is 58.8 N.cm into steel, 39.2 N.cm into cast iron and 29.4 N.cm into aluminium for M2 screws, or 196, 127 and 98 N.cm for M3. Keep the ambient temperature at or below 80 C, with transient peaks to 100 C, and 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 for this model on request.
You receive the complete set: the 295 mm stainless-steel rail and one pre-greased standard-length carriage already fitted to it. Mounting screws and top-up grease are not included - grease is injected through the lubrication hole at the rear of the carriage, and different lubricant types must never be mixed. Note this is a mechanical guide, not a pneumatic part, so there is no air connection to plan for. If you later want a spare carriage on its own, our carriage-only stock is very thin - just a handful of SKUs - so a spare usually means a special order.
