Airtac LRM Miniature Linear Guide LRM12L1X245S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X245S10AP 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 LRM12L1X245S10AP
LRM12L1X245S10AP is a complete set: one 245 mm stainless-steel rail, 12 mm across, with its end holes set 10 mm in from each end, plus a single long recirculating-ball carriage. No trailing T means top-mount fixing - screws go down through the rail into the base, and either long edge of the rail can serve as the datum face.
Preload grade A means none, so this is the freest-running carriage in the LRM12 range: minimal drag, easy manual positioning and less heat build-up in continuous cycling. The price is measurable clearance, which matters if your motion reverses under side load. Accuracy grade P sits at the top of what this series offers. The recirculating balls are Japanese ISO 3290 G10 - a ball-grade statement only, not a standard for the assembly. Keep the ambient under 80 C (transients to 100 C), and note that on an inclined rail the carriage can slide off under its own weight, so hold it during handling. Load and moment ratings are not published for this series; we will confirm the figures for this exact 245 mm configuration when you enquire.

Where the Airtac LRM Miniature Linear Guide LRM12L1X245S10AP Is Used
High-cycle tray indexing
Zero preload keeps drag low on a slide that indexes semiconductor trays every second, limiting heat rise over a 245 mm back-and-forth motion.
Fiber-optic alignment fixture
Precision grade P and a free-running carriage let an operator feather a fiber chuck into position by feel before clamping it down.
Measuring microscope focus
Top-mount fixing suits an instrument base: the rail bolts down onto the milled deck of a small measuring scope's focus stage.
Is the Airtac LRM Miniature Linear Guide LRM12L1X245S10AP the Right Guide?
Choose with the load question open, not closed. If the application turns out to need published sizing numbers - dynamic, static or moment ratings - LSH is the series that publishes them and LRM is not, so step up. If the travel is short and rigidity per millimetre matters most, crossed-roller LGC is worth a look. Confirming this set means agreeing: complete-set form, 12 mm rail, long carriage, one carriage, 245 mm rail length, preload A, precision accuracy, top-mount direction - then a load rating confirmed with 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 LRM12L1X245S10AP FAQ
12 mm rail width; 245 mm rail length with 10 mm end offset; one long carriage; preload A (none); accuracy P (precision); top-mount rail. Fixing screws torque to 58.8 N.cm (M2) or 196 N.cm (M3) in steel, with lower values in cast iron and aluminium. Ambient temperature limit is 80 C with 100 C transients, and lubrication is topped up every 100 km of travel or 3 to 6 months. Load and moment ratings are not published for LRM; we confirm them per model.
One 245 mm stainless rail and one long carriage assembled on it, pre-greased with Kyodo Yushi PS No. 2 - and nothing else. No second carriage, no end stops, no mounting screws. Before first use, wipe off the rust-preventive oil and apply fresh lubricant of the same type; never mix lubricants of different families.
