Airtac LRM Miniature Linear Guide LRM12L1X145S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X145S10AH 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 LRM12L1X145S10AH
This is the complete LRM12L1X145S10AH set from AirTAC: one long recirculating-ball carriage riding a 145 mm stainless-steel rail, 12 mm wide, cut with a 10 mm end-hole offset for the fixing screws. The long body spreads the ball contact over a greater length than the standard carriage, which helps any part of the load that wants to tip. The box contains exactly what the code says - rail and carriage, assembled and pre-greased, nothing else to buy.
Design points worth knowing: the ball-retention feature holds the recirculating balls (rated ISO 3290 G10, Japanese made) captive during handling, a double-lip seal scrapes oil and excludes dust, and the outer cover shields the seal strip and screw line. Ambient temperature must stay at or below 80 C with brief peaks to 100 C - a real limit if the stage sits beside a heater or a lamp. No load rating is published for the LRM series, so we confirm the capacity of this exact model before you order; send the RFQ and we will come back with the figure.

Where the Airtac LRM Miniature Linear Guide LRM12L1X145S10AH Is Used
Microscope camera stage
A benchtop inspection microscope carries its camera head along this 145 mm rail; the long carriage steadies the overhanging camera and grade H accuracy keeps the image plane true through the stroke.
SMD prototype pick-and-place
A small pick-and-place head placing 0402 passives on prototype boards runs on this set; with no preload the head glides freely under its own weight, which suits a light friction drive.
Optical bench alignment slide
An alignment laser is trammed along a 145 mm track on the optical bench; the 12 mm stainless rail bolts straight to the tapped bench plate using the top-mount holes.
Is the Airtac LRM Miniature Linear Guide LRM12L1X145S10AH the Right Guide?
Start the match with the form: this is a complete set, not a carriage alone. Fix rail width at 12 mm, carriage length long, one carriage, 145 mm of rail, no preload (grade A), accuracy H, top-mount fixing. Grade A gives the freest-running motion of the three LRM preload grades, at the cost of a little clearance - if the play must come out, look at grade B or C. When the load is substantial or cantilevered, step up to LSH instead: it publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not. For short travel where crossed-roller rigidity matters, LGC is the closer match. Whatever you choose, confirm the load rating with us before committing.
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 LRM12L1X145S10AH FAQ
Rail width 12 mm, rail length 145 mm, one long carriage, preload grade A (none), accuracy grade H (high), top-mount rail with a 10 mm end-hole offset. Mounting screws take M2 at 58.8 N.cm into steel (39.2 cast iron, 29.4 aluminium) or M3 at 196 N.cm into steel (127 cast iron, 98 aluminium). The carriage ships pre-filled with Kyodo Yushi PS No. 2 grease; re-grease every 100 km of travel or every 3 to 6 months. Ambient temperature must not exceed 80 C, with transient peaks to 100 C. Basic dynamic and static load ratings and moment ratings are not published for LRM - we confirm them for this specific model on request.
Choose LRM when the envelope is tight and the duty is light, as here: a 12 mm rail on a 145 mm track suits compact stages. Choose LSH when the load is heavy or overhung, because LSH publishes dynamic, static and moment ratings per carriage that you can calculate against, while LRM publishes no load figures at all. If the design needs a calculated margin, LSH is the safer pick; if it needs the small footprint, send us the RFQ and we will confirm what the LRM12L1X145S10AH can carry.
