Airtac LRM Miniature Linear Guide LRM12N2X245S10BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X245S10BP 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 LRM12N2X245S10BP
This is LRM12N2X245S10BP, a complete set: 12 mm stainless rail, 245 mm of travel, two standard-length carriages, machined to precision (P) accuracy rather than the standard high (H) grade. Rail and carriages are supplied together, greased and ready to bolt down. Note how the price of this range behaves: stocked sets run from about $66 to $831 across only two rail widths, so rail length and carriage count - not size - drive the cost.
P grade is the choice when the stage has to hold position without visible drift along the travel: inspection fixtures, alignment work, anything that gets measured against. The balls inside each carriage are ISO 3290 G10 Japanese balls, held by the retention design during handling; a double-lip seal and outer cover protect the raceway and the seal strip from oil loss and debris. Keep the surroundings at or below 80 C, with brief peaks to 100 C. Load and moment figures are not published for LRM - confirm with us per model and we will quote them for this exact code.

Where the Airtac LRM Miniature Linear Guide LRM12N2X245S10BP Is Used
Precision lens alignment stage
P-grade tolerances suit a small optic-aligning carriage where position drift along the travel shows up straight away in the image.
Miniature sensor assembly cell
A light epoxy or screwdriver head riding on two standard carriages handles fine electronics assembly, and the 12 mm rail slots into tight cell layouts.
Custom measuring fixture build
When building a one-off inspection jig, the common-rail design lets you pick carriage variants against the same 12 mm rail profile as the layout evolves.
Is the Airtac LRM Miniature Linear Guide LRM12N2X245S10BP the Right Guide?
Match the code to the drawing line by line: set form, 12 mm rail, standard block, two per rail, 245 mm length, preload B (light), accuracy P for tighter tolerance work, top-mount rail. Include the load and moment check last but do not skip it - LRM has no published ratings, so we verify them for this model number before the order goes in.
When to look elsewhere: step up to LSH if the load is substantial or reaches out on a cantilever, because LSH publishes per-carriage dynamic, static and moment figures you can size against. Step across to LGC when travel is short and the job wants crossed-roller rigidity.
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 LRM12N2X245S10BP FAQ
Rail: stainless steel, 12 mm wide, 245 mm long, top-mount. Carriages: two, standard length, preload B (light), accuracy P. Screws: the catalogue table lists M3 at 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium, and M2 at 58.8 / 39.2 / 29.4 N.cm. Ambient temperature: 80 C maximum, transient peaks 100 C. Lubrication: re-grease every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM; we confirm the figures for this model when you send the RFQ.
A complete set: the 245 mm stainless rail plus both carriages mounted and pre-filled with grease. P is the precision grade above H, produced to tighter tolerances for work that gets measured - alignment stages, inspection fixtures, metrology jigs. If you ever need a rail without carriages or a black-chrome finish, those exist in the catalogue but are not stocked; we order them in.
