Airtac LRM Miniature Linear Guide LRM12N1X245S10CPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X245S10CPT 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 LRM12N1X245S10CPT
The LRM12N1X245S10CPT combines two specification choices on one 245 mm, 12 mm wide stainless-steel rail: precision grade accuracy and a bottom-mount rail, with a single standard-length carriage. Nothing else comes in the box - one rail, one carriage, fitted and ready to bolt down from underneath.
Bottom mounting suits frames where the top face must stay clear for the moving payload or a cover; you reach the fixing screws from below, through the rail. Precision grade tightens travel tolerance, so the mounting surface matters more: grind or finish-mill it, and if you ever add carriages, keep the datum face on the same side of the rail for each one. Ball retention keeps the balls in place during handling but is not a guarantee - angle the carriage onto the rail and balls can still escape, so a dummy rail helps when fitting carefully. Do not strike or drop the rail, since accuracy can suffer without visible damage. AirTAC publishes no load or moment ratings for LRM; tell us the duty in your RFQ and we confirm the figures for this exact model.

Where the Airtac LRM Miniature Linear Guide LRM12N1X245S10CPT Is Used
Tape-and-reel inspection bench
An electronics bench that pulls components from tape for inspection can run a small camera slide on this guide. The bottom-mount rail leaves the benchtop clear for fixtures and trays.
Wire-feed tensioning slide
A compact slide that guides fine wire under light tension benefits from precision travel and a stiff, preload-C carriage. Keep ambient heat sources away - the guide is rated to 80 C with brief peaks to 100 C.
Benchtop dispensing head
A low-volume glue or solder-paste dispenser mounted on a short X-axis gains repeatable needle positioning from precision grade travel. Wipe the rust-preventive oil off and lubricate before first use.
Is the Airtac LRM Miniature Linear Guide LRM12N1X245S10CPT the Right Guide?
Choose with the checklist, then step sideways if the maths gets tight. LSH is the series to step up to when loads grow or the carriage works on a cantilever, because LSH publishes the dynamic, static and moment ratings LRM withholds. LGC wins when travel is short and you need crossed-roller rigidity. Here: confirm you want a complete set, 12 mm wide rail, 245 mm long, one standard carriage, preload C, precision grade P, bottom-mount. Precision grade rewards a properly prepared mounting surface. Send the load details with your RFQ and we confirm the ratings for this model.
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 LRM12N1X245S10CPT FAQ
Rail width 12 mm, rail length 245 mm, one standard-length carriage, preload C (medium), accuracy grade P, rail mounted from below. Use M2 screws at 58.8 N.cm into steel, 39.2 N.cm into cast iron and 29.4 N.cm into aluminium. The ambient limit is 80 C with transient peaks to 100 C, and the grease interval is every 100 km of travel or every 3 to 6 months, whichever comes first. Load, moment and speed ratings are not published for the LRM series - we confirm them for this specific model before you order.
One rail and one carriage, nothing more: a 245 mm, 12 mm wide stainless-steel rail, bottom-mount, with a single standard carriage fitted at the factory. Handle the assembly carefully - the ball retainer limits ball loss, but tipping the carriage onto the rail or swapping it quickly can still drop balls, and a dummy rail makes safe fitting easier. Do not strike the rail or dismantle the carriage. Spare carriages alone are ordered by a pairing code matched to the rail; our carriage-only stock is thin, so most are special orders.
