Airtac LRM Miniature Linear Guide LRM12L1X145S10CPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X145S10CPT 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 LRM12L1X145S10CPT
LRM12L1X145S10CPT pairs the two specification choices that trade least in availability: a bottom-mount rail and a precision P accuracy grade. The set is a 12 mm wide, 145 mm long stainless steel rail with one long carriage, medium preload C, screws entering the rail from underneath, and a 10 mm end-hole offset.
A practical point for anyone planning service swaps: the ball-retention design reduces but does not remove the risk of dropped balls, so slide the carriage on square and avoid hurried removal - a dummy rail is the manufacturer's suggested aid. The carriage rides on Japanese ISO 3290 G10 balls (balls only, not an assembly standard) behind a double-lip seal and outer cover, and the ambient limit is 80 C with 100 C peaks allowed briefly. Load capacity is confirmed per model rather than published; ask us and we will verify the figure before you order.

Where the Airtac LRM Miniature Linear Guide LRM12L1X145S10CPT Is Used
Optical assembly cell
A lens-assembly station in a small optics production cell, with the rail sunk into the table so fixtures can sit flush across the working deck.
Vinyl cutter carriage
The blade-carriage upgrade path for a desktop vinyl or pen plotter, where a precision-grade long carriage steadies the tool across a 145 mm sweep.
Autofocus slide
A microscope autofocus stage on an optical breadboard, mounted from underneath so the sample area above stays unobstructed.
Is the Airtac LRM Miniature Linear Guide LRM12L1X145S10CPT the Right Guide?
Run through the checklist before ordering: complete set, 12 mm rail width, 145 mm rail length, one long carriage, medium preload C (the rigid choice, but it punishes uneven mounting faces), precision P accuracy, bottom-mount fixing, 10 mm end-hole offset. Then settle the sizing question: LRM has no published load or moment ratings, so confirm the figure with us for this model. If the load turns out heavy or sits on a cantilever, AirTAC LSH is the upgrade - it publishes per-carriage dynamic, static and moment ratings. Where travel is short and crossed-roller rigidity matters more than ball smoothness, LGC is the alternative.
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.

Yes - this code is a complete set with the carriage already on the rail. A spare, though, is a different story: carriages are coded A to E to pair with their rail, and a replacement must carry the same letter, which you read off the original part. Our carriage-only stock currently runs to only a handful of SKUs, so most spare carriages are ordered in specially rather than pulled from the shelf.
