Airtac LRM Miniature Linear Guide LRM12L2X495S10BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X495S10BP 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 LRM12L2X495S10BP
The LRM12L2X495S10BP pairs familiar LRM12 hardware with a tighter accuracy grade: a 12 mm stainless-steel rail cut to 495 mm, two long recirculating-ball carriages, light preload B, and P for precision rather than H for high. The S10 end offset and the top-mount screw pattern stay the same, and one box holds the rail plus both factory-lubricated blocks.
Choosing precision grade is about what you will not have to do afterwards: the tighter P tolerances on carriage geometry and travel accuracy mean less shimming and scraping when you bed the rail onto a ground or finish-milled surface. The ball-retaining design keeps the ISO 3290 G10 Japanese balls in their raceways during handling, and a double-lip seal plus outer cover protect the track from dust and oil loss. Note also that most of the listed LRM range sits at size 12, so this configuration is the well-served heart of the series. Ambient temperature must stay at or below 80 C, briefly up to 100 C. No load or moment rating is published for LRM; ask us on the RFQ and we will confirm the figure for this exact code.

Where the Airtac LRM Miniature Linear Guide LRM12L2X495S10BP Is Used
Watch and medical part measuring fixture
A granite-based inspection fixture probing watch bridges or bone screws, where precision-grade running accuracy keeps the probe path true without post-installation shimming.
Fiber-optic component alignment stage
Aligning ferrules and lensed fibers under power-meter feedback: the light-preload carriage glides in small increments while the precision grade holds the optical axis repeatable.
Digital microscope cross-slide
A fine X-axis under a bench microscope traversing circuit boards or fracture surfaces, where P-grade travel parallelism keeps depth of field stable across the full 495 mm.
Is the Airtac LRM Miniature Linear Guide LRM12L2X495S10BP the Right Guide?
Match the series to the mechanics before the code. If the plate carries real weight or a cantilevered load, LSH is the honest step up - it publishes dynamic, static and moment ratings per carriage that you can actually calculate against, which LRM deliberately does not. If the travel is short and you need crossed-roller stiffness in a small footprint, look at LGC. For this set, tick off: complete-set form, 12 mm rail width, long carriage, two blocks on one 495 mm rail, light preload B (free-running, less rigid than C), precision accuracy P, top-mount direction, and the 10 mm hole offset. Then confirm the load rating with us - it is settled per model, never assumed.
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 LRM12L2X495S10BP FAQ
Published and quotable: 12 mm rail width, 495 mm rail length, long carriages, two per rail, light preload B, precision accuracy P, top-mount fixing and a 10 mm end-hole offset. Screw torque is 58.8 N.cm for M2 and 196 N.cm for M3 into steel (39.2 and 127 N.cm into cast iron, 29.4 and 98 N.cm into aluminium). Regrease with Kyodo Yushi PS No. 2 every 100 km of travel or every 3 to 6 months, and keep the ambient at or under 80 C with peaks to 100 C. What is deliberately not published: load and moment ratings. We confirm them for this exact model when you enquire.
Decide by what you need to verify. LRM is built for miniature, light-duty positioning and gives you no published load table - the rating is confirmed per model through us. LSH, the larger series, publishes dynamic, static and moment ratings per carriage, so if your sizing depends on working those numbers, or the load is simply beyond miniature scale, start there instead. For compact, low-load stages, this LRM set is the right order of magnitude.
