Airtac LRM Miniature Linear Guide LRM12L1X495S10BH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X495S10BH 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 LRM12L1X495S10BH
LRM12L1X495S10BH is a complete AirTAC LRM miniature linear guide set: one 495 mm stainless-steel rail, 12 mm wide, carrying a single long recirculating-ball carriage. The end-hole offset is 10 mm, the preload grade is B (light) and the accuracy grade is H (high). The carriage arrives fitted to the rail, pre-filled with grease, and bolts down from above with cap screws.
The long body spreads the ball contact over a greater footprint and lengthens the bearing span, which helps when a small overhung load tries to tip the carriage. Like every LRM carriage, this one shares the common LRM rail profile, keeps its balls captive for handling through the ball-retention design (though the maker warns balls can still drop if the carriage is angled on or swapped hastily), and runs on ISO 3290 G10 grade balls - a grade that applies to the balls themselves, not to the guide assembly. A double-lip seal scrapes oil and excludes dust, and an outer cover hides the screws and shields the seal strip. Ambient temperature must stay at or below 80 C, with peaks no higher than 100 C, which matters beside a heater or a warm enclosure wall. Load and moment ratings are not published for LRM; we confirm the figures for your exact model before ordering - send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X495S10BH Is Used
SMT pick-and-place gantry
A tabletop SMT prototype placer moving a lightweight vacuum head along a 495 mm axis; the long carriage keeps the head square over the board.
Optical inspection bench
Sliding a small camera or microscope objective across a PCB sample on a benchtop metrology rig, where smooth, repeatable H-grade travel matters more than raw capacity.
Laser alignment slide
Fine-positioning a compact laser diode module in an optics lab setup; the light B preload keeps motion easy while limiting slop on reversal.
Is the Airtac LRM Miniature Linear Guide LRM12L1X495S10BH the Right Guide?
Size up when the load is substantial or cantilevered: AirTAC LSH publishes per-carriage dynamic, static and moment ratings you can calculate against, while LRM does not, so a real load case should be checked with us first. Step across to LGC when travel is short and the job needs crossed-roller rigidity. Before ordering this set, work the checklist: form (complete set), rail width 12 mm, long carriage, one carriage, 495 mm rail, light B preload - the trade-off is a little play in exchange for lower drag - accuracy H, top-mount rail, and the load rating confirmed with us. On availability: size 12 makes up the great majority of the LRM sets we list, so a design laid out around a 12 mm rail is the easiest to source, and long carriages are listed about as widely as standard ones here, so choosing L for a tipping load costs nothing in availability.
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 LRM12L1X495S10BH FAQ
Rail width 12 mm; rail length 495 mm; one long carriage; end-hole offset 10 mm; preload B (light); accuracy H (high); top-mount rail. Use M3 cap screws - 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium. Ambient temperature must not exceed 80 C, with peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months. Basic dynamic load, static load and moment ratings are not published for LRM - we confirm them per model, so ask us before committing.
Choose LRM for a tight envelope and light-duty precision travel; choose LSH when the load is heavier or overhung, because LSH publishes dynamic, static and moment ratings per carriage that you can size against, and it gives you a wider rail for stiffness. If travel is short and you need crossed-roller rigidity instead, look at LGC. For either alternative, send us the load sketch and we will confirm the right part.
