Airtac LRM Miniature Linear Guide LRM12L1X495S10BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X495S10BP 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 LRM12L1X495S10BP
This is the precision-grade version of the 495 mm size-12 set: LRM12L1X495S10BP is one 12 mm wide stainless-steel rail finished to accuracy grade P, cut to 495 mm with a 10 mm end-hole offset, carrying a single long recirculating-ball carriage that ships fitted and pre-greased with Kyodo Yushi PS No. 2.
Grade P is the tighter of the two accuracy grades stocked for LRM, the right pick when a measurement or alignment axis has to hold its line without reworking the mounting bench. Common-rail design means other LRM12 carriages share this rail profile if you extend the axis later. Note what actually drives price in this family: stocked LRM sets span roughly $66 to $831 across only two rail widths, so rail length and carriage count dominate the bill, not the width. Ball retention keeps the ISO 3290 G10 Japanese balls in the carriage during handling; a double-lip seal and outer cover keep grease in and debris out. Keep ambient temperature at or below 80 C. Load and moment ratings are not published for this series - we confirm them per model, so raise an RFQ before ordering.

Where the Airtac LRM Miniature Linear Guide LRM12L1X495S10BP Is Used
Semiconductor die inspection stage
Stepping a microscope between die on a wafer piece: grade P tolerances support repeatable positioning, and the stainless rail suits a clean bench environment.
Fiber-optic coupling fixture
Bringing a fiber chuck to a lens or detector in small increments, where the precision-grade rail and long carriage give a steadier platform than a short standard block.
Connector test rack slide
Sliding a test head across board-to-board connectors in a rack: the 495 mm rail covers a multi-connector pitch in one piece, with no rail joint in the middle of the pitch.
Is the Airtac LRM Miniature Linear Guide LRM12L1X495S10BP the Right Guide?
Price in this range follows length, not width: stocked LRM sets run from about $66 to $831 across only two rail widths, so a 495 mm rail with a single long carriage sits mid-span and trimming travel is the quickest saving. Around that, confirm the rest of the code against your drawing: complete-set form, 12 mm rail, long carriage, one block, preload B, precision grade P, top-mount fixing.
Step up to AirTAC LSH when the load is real or cantilevered - LSH gives you published dynamic, static and moment ratings per carriage to calculate with, which LRM never does. Step across to LGC when the travel is short and crossed-roller rigidity is the priority. Before ordering, send the RFQ so we confirm the load and moment figures for this exact precision-grade model.
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 LRM12L1X495S10BP FAQ
Rail width 12 mm; rail length 495 mm with a 10 mm end-hole offset; one long carriage; preload B (light); accuracy grade P (precision); top-mount rail fixing. Screw torque table from the datasheet: M2 screws 58.8 N.cm into steel (39.2 cast iron, 29.4 aluminium); M3 screws 196 N.cm into steel (127 cast iron, 98 aluminium). Ambient temperature limit 80 C, transient peaks 100 C. Re-grease with Kyodo Yushi PS No. 2 every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM; the figures are confirmed for this exact model on request.
If the load is heavy or hangs off the carriage, LSH is the safer engineering choice: it publishes dynamic, static and moment ratings per carriage, so you can size it on paper, whereas LRM publishes none and the rating has to be confirmed with us per model. If travel is short and you need the stiffness of crossed rollers, LGC fits better. Keep LRM where space is tight and duty is light. For this precision-grade set in particular, confirm the load figure by RFQ before you finalize the design.
