Airtac LRM Miniature Linear Guide LRM12L1X495S10CH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X495S10CH 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 LRM12L1X495S10CH
The LRM12L1X495S10CH is a complete miniature linear guide: a 495 mm stainless-steel rail, 12 mm wide, carrying one long-series recirculating-ball carriage. Mounting holes run along the rail with a 10 mm offset from each end, and you fasten the rail down from above with M3 screws. Everything needed for one light-duty axis ships together in the box.
The long body is the point of this code: it spreads contact over more recirculating balls and stretches the bearing span, which is the cheapest way to steady a tipping or overhanging component. Preload C (medium) takes up the internal clearance, so the slide feels firm, but it punishes sloppy mounting - the manufacturer expects a ground or finish-milled surface. The balls inside are Japanese-made to ISO 3290 G10 for roundness and wear, a grade that applies to the balls themselves and not to the assembly. A double-lip seal scrapes oil and dust, an outer cover hides the screws and screens larger debris, and the ambient temperature must stay at or below 80 C. Load and moment ratings are not published for LRM; we confirm the figures for your exact model when you send an RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X495S10CH Is Used
Desktop pick-and-place head
A long carriage on a 495 mm rail suits the main axis of a compact desktop pick-and-place, where the head overhangs the guide and the extended bearing span limits tipping near the ends of stroke.
Optics alignment bench
Laboratory beam-alignment fixtures gain from preload C: with no internal play, a mirrored carriage returns to the same position cycle after cycle across the full half-metre of travel.
PCB camera inspection slide
A vision camera traversing a populated circuit board needs smooth, repeatable motion; the H grade and stainless rail keep the image path consistent over hundreds of passes.
Is the Airtac LRM Miniature Linear Guide LRM12L1X495S10CH the Right Guide?
At 495 mm, this rail is roughly half the 1005 mm catalogue maximum for size 12, so it arrives as a single section - no splice marks to align and no accuracy penalty from a joint. If your load is substantial or hangs off a cantilever, step up to the LSH series instead: it publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not. For short travels that need crossed-roller rigidity, look at LGC. Before committing, check off: complete set or carriage only, 12 mm rail width, long carriage, one block on this rail, preload C versus the easier-to-install A or B, accuracy grade H, top-mount rail, and a confirmed load rating from us.
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 LRM12L1X495S10CH FAQ
Rail width 12 mm, rail length 495 mm, one long carriage, preload C (medium), accuracy grade H, rail bolted from above (top-mount). M3 fixing screws torque to 196 N.cm in steel, 127 N.cm in cast iron and 98 N.cm in aluminium. Ambient temperature must not exceed 80 C, with transient peaks to 100 C. Re-grease with Kyodo Yushi PS No. 2 or equivalent every 100 km of travel or every 3 to 6 months, whichever comes first. Basic dynamic and static load ratings and allowable moments are not published for LRM; request them per model and we will confirm before you order.
Choose LRM when the envelope is tiny and the duty is light: a 12 mm rail and a long but small carriage fit where a full-size guide cannot. Choose LSH when the load is heavy or cantilevered, because LSH publishes dynamic, static and moment ratings you can calculate with, while LRM ratings must be confirmed per model. It also helps that size 12 is the deepest-stocked LRM size - 924 of the 988 complete sets we hold - so a 495 mm length like this one ships fastest.
