Airtac LRM Miniature Linear Guide LRM12L1X445S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X445S10CP 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 LRM12L1X445S10CP
One complete guide set, precision grade: the LRM12L1X445S10CP combines a 12 mm wide stainless-steel rail, 445 mm in length, with a single long recirculating-ball carriage fixed from above. The P in the code marks the precision accuracy grade - the tighter of the two grades offered on LRM - for builds where repeatability of position counts more than keeping cost down. The set arrives pre-lubricated and ready to install.
Long carriages are stocked as deeply as standard ones in this range (512 against 475 live sets), so specifying the extra bearing span for a tipping load costs nothing in availability here. Preload C gives a rigid, clearance-free motion, though it expects a ground or finish-milled mounting surface to deliver its full accuracy. The carriage runs on ISO 3290 G10 grade Japanese balls for roundness, sealed by a double-lip design and shielded by an outer cover that also hides the fixing screws. Keep the ambient at or under 80 C - with peaks no higher than 100 C - which matters if the stage sits near a soldering process or a hot lamp. No load or moment rating is published for LRM; we confirm the numbers for this exact model through the RFQ before you commit.

Where the Airtac LRM Miniature Linear Guide LRM12L1X445S10CP Is Used
Measuring microscope stage
Precision grade P keeps a small part's position repeatable under the optic across the full 445 mm travel, with the long carriage damping any nod of the sample holder.
Semiconductor tray indexer
A chip-tray stepping axis on a 12 mm rail fits cramped machine envelopes, and the precision grade helps the pick head land on the same pocket every cycle.
Fiber-optic coupling fixture
Aligning ferrules and lenses demands positional repeatability rather than brute capacity - exactly where a precision-grade, medium-preload miniature guide earns its keep.
Is the Airtac LRM Miniature Linear Guide LRM12L1X445S10CP the Right Guide?
This is a top-mount complete set: 12 mm rail, 445 mm long, one long carriage, preload C and precision accuracy P. Tick off each against your drawing before ordering - especially accuracy, because P is the grade to pick when the guided axis feeds a measurement or alignment function. If your load is heavy or overhung, move up to LSH, whose catalogue lists per-carriage dynamic, static and moment ratings you can work with; LRM publishes none of these. For very short travels where crossed-roller rigidity is the priority, compare LGC. Whatever the series, confirm the load rating with us before ordering - for LRM that figure is issued per model, and we will supply it against your RFQ.
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 LRM12L1X445S10CP FAQ
Rail width 12 mm, stainless steel, cut to 445 mm; one long recirculating-ball carriage; preload C (medium); accuracy grade P (precision); rail fixed from above (top-mount). Screws torque to 58.8 N.cm into steel with M2 fasteners (39.2 cast iron, 29.4 aluminium) or 196 N.cm with M3 (127 / 98). Ambient limit is 80 C, brief peaks to 100 C. Re-lubricate every 100 km of travel or every 3 to 6 months with a compatible grease. Dynamic load, static load and moment ratings are not published for LRM - we confirm them per model, so include them in your RFQ.
A complete, matched assembly: the 445 mm stainless-steel rail with one long carriage already fitted and pre-greased, ready to bolt to a ground or finish-milled surface. There is no second carriage, no mounting hardware beyond what the design requires, and no rail in a separate carton - this is not a carriage-only code. Note that the carriage is not meant to be slid off for fitting; if you expect to swap carriages in the field, tell us, because carriage-only spares are a thin part of our stock and usually a special order.
