Airtac LRM Miniature Linear Guide LRM12N2X895S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X895S10AH is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriages. 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 LRM12N2X895S10AH
The LRM12N2X895S10AH is a long, single-piece miniature guide set: a 12 mm wide stainless-steel rail of 895 mm carrying two standard carriages, preload-free, accuracy H, mounted from the top. At 895 mm it sits just below the 1005 mm catalogue full length for size 12, so it delivers nearly the longest continuous stroke a single LRM12 rail can give you without resorting to a spliced two-section rail.
A long stroke changes the service maths. The re-grease interval is every 100 km of travel or every 3 to 6 months, whichever comes first - and a 200 mm stroke cycling once per second covers 100 km in roughly three weeks of continuous running, so on a rail like this the distance binds long before the calendar does. The set uses ISO 3290 G10 Japanese balls (the grade refers to the balls alone), a double-lip seal and an outer cover along the screw line. Never strike or drop the rail: accuracy and life can suffer with no visible damage. Stiffness and load capacity are confirmed per model - the maker publishes no load table for LRM, so send the RFQ with your duty cycle and we will confirm the figures.

Where the Airtac LRM Miniature Linear Guide LRM12N2X895S10AH Is Used
Inkjet printer carriage
A wide-format inkjet carriage sweeping an 895 mm print width matches this near-full-length rail; long strokes are exactly the case where rail length, not rail width, dominates the price.
Wafer inspection shuttle
A semiconductor inspection shuttle carrying wafers between stations uses the long single-piece rail to avoid joints anywhere in the travel; spliced sections only become necessary beyond the catalogue full length.
Clinical analyzer sampler
An automated clinical analyzer moving a sampling arm over reagent trays must respect the 80 C ambient limit found near lab heat sources, and the double-lip seal keeps the factory-filled grease working between top-ups.
Is the Airtac LRM Miniature Linear Guide LRM12N2X895S10AH the Right Guide?
If the application carries meaningful weight or a cantilevered arm, LSH is the honest step up: it publishes per-carriage dynamic, static and moment ratings you can drop straight into a calculation, something LRM does not offer. Short-travel jobs demanding crossed-roller rigidity belong with LGC instead. Check this set against your layout: 12 mm rail width, 895 mm rail, two standard carriages, preload A, accuracy H, top-mount fixing, S10 end offset. Confirm the load and moment rating with us at RFQ stage - that confirmation is part of specifying LRM properly.
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 LRM12N2X895S10AH FAQ
Rail width 12 mm, rail length 895 mm, two standard-length carriages on one rail, preload A (none), accuracy H (high), top-mount rail, 10 mm end-hole offset. Fixing torque: M2 screws 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminum; M3 screws 196, 127 and 98 N.cm respectively. Ambient limit 80 C, transients 100 C. Re-grease every 100 km of travel or every 3-6 months through the hole at the rear of each carriage. Load and moment ratings are not published for LRM; we confirm them per model.
One 895 mm stainless-steel rail with both standard carriages assembled on it, shipped coated in rust-preventive oil - wipe it off and lubricate before first use. Before storing, coat evenly with rust-preventive oil, seal in the bag, lay flat and keep away from heat and humidity. On an inclined surface the carriages can slide under their own weight, so hold them when handling. Note the mounting surface should be ground or finish-milled, and with two carriages put the datum face on the same side for better running accuracy.
