Airtac LRM Miniature Linear Guide LRM12N1X445S10CH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X445S10CH 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 LRM12N1X445S10CH
This LRM12N1X445S10CH is a complete AirTAC LRM miniature linear guide: one 445 mm stainless-steel rail, 12 mm wide, with a single standard-length recirculating-ball carriage pre-fitted at the factory. The code also fixes a 10 mm end-hole offset, medium preload (grade C), high accuracy (grade H) and a rail fastened through its top face. What arrives is the matched rail-and-carriage assembly, already charged with grease.
Preload C is the tightest grade offered on LRM, so the carriage runs with minimal play along the full 445 mm span - a good match where backlash would show up in the process, provided the mounting face is ground or finish-milled, because a medium-preload carriage is the least forgiving of surface error. Inside, the carriage runs on Japanese-made balls graded ISO 3290 G10 for roundness, a double-lip seal scrapes oil and excludes dust, and an outer cover shields the seal strip from larger debris. Keep the ambient temperature at or below 80 C, with peaks no higher than 100 C. Load and moment ratings are not published for the LRM series; we confirm the figures for this exact configuration when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X445S10CH Is Used
Compact glue-dispensing stage
A desktop dispensing machine laying beads on small housings benefits from the near-zero play of the medium-preload carriage across the 445 mm span.
SMT pick-and-place head
A light gantry axis carrying a vacuum head between feeder and board, where the 12 mm rail keeps the cross-section slim and the top-mount fixings stay accessible.
Microplate shuttle in a lab analyzer
Short, repeatable plate moves inside analytical instruments suit a light-duty miniature guide of this width and accuracy grade.
Is the Airtac LRM Miniature Linear Guide LRM12N1X445S10CH the Right Guide?
Choose LRM when the envelope is tight and the motion is light-duty precision positioning; step up to LSH when the load is substantial or cantilevered, since LSH publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not. If travel is short and crossed-roller rigidity matters more than stroke, LGC is the better fit. Size 12 dominates the LRM range listings, so a layout built on a 12 mm rail is the easiest configuration to source in this series. Before ordering, tick off: form (this is a complete set, not a spare carriage), 12 mm rail width, standard carriage length, one carriage, 445 mm rail, 10 mm end offset, preload C, accuracy H, top-mount direction, and a load rating confirmed with us. Within LRM12, price tracks rail length and carriage count far more than rail width, so trimming travel is the first lever on cost.
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 LRM12N1X445S10CH FAQ
Rail width 12 mm, rail length 445 mm, one standard-length carriage, 10 mm end-hole offset, medium preload C, high accuracy H, top-mount rail. Screw torque is 58.8 N.cm for M2 screws and 196 N.cm for M3 screws into steel, with lower values into cast iron and aluminium. Ambient temperature must stay at or below 80 C, peaking no higher than 100 C. Re-grease with Kyodo Yushi PS No. 2 every 100 km of travel or every 3 to 6 months, whichever comes first. Load and moment ratings are not published for LRM; we confirm them per model before you order.
Grade C pulls the internal clearance down to almost nothing, so positioning is crisp and the carriage shows no perceptible rock. The cost is higher sliding resistance than the light-preload grades and a stricter demand on the mounting surface: grind or finish-mill the rail seat, and plan your hole pattern around the 10 mm end offset. If the machine can tolerate a little free play in exchange for freer-running motion, the same 445 mm rail is offered with light preload B.
