Airtac LRM Miniature Linear Guide LRM12N2X445S10CH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X445S10CH 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 LRM12N2X445S10CH
This is the firmest standard configuration in the S10 family of 445 mm LRM12 rails: LRM12N2X445S10CH pairs medium preload C with high accuracy H, on one 12 mm wide stainless rail, 445 mm long, carrying two standard carriages and fixed from the top.
Preload C removes most internal play, which pays off wherever a direction reversal would otherwise show as lost motion - but it also runs with more drag and forgives a poorer mounting surface less, so grind or finish-mill the base and keep the datum edge on one side for both carriages. Inside, the double-lip seal manages the Kyodo Yushi PS No. 2 grease, the outer cover keeps chips off the seal strip, and the recirculating balls are Japanese ISO 3290 G10 grade. Ambient must stay at or below 80 C. Load and moment ratings are not published for LRM, so the working figures for this set are confirmed per model - raise an RFQ and we will supply them.

Where the Airtac LRM Miniature Linear Guide LRM12N2X445S10CH Is Used
Vial sorting tray
A light sorting head sweeping across vial lanes; medium preload C removes reversal play so the head returns to each lane stop without drift.
Micro dispensing cell
Guiding a syringe dispenser over a small pad grid on a PCB; the two-block arrangement resists tipping at the dispense point where the needle meets the board.
Workshop jig slide rebuild
Replacing a worn slide in a small workshop jig: the pre-assembled twin-carriage set drops onto a milled plate and needs only M3 screws and a grease top-up.
Is the Airtac LRM Miniature Linear Guide LRM12N2X445S10CH the Right Guide?
Choose this code when repeatability through reversal matters more than a free-sliding feel. Then size it honestly: LRM publishes no C, C0, moment or parallelism figures, so the capacity question ends with us - describe the duty and we confirm the rating for this exact model. A heavy or overhung load belongs on the LSH series, which publishes dynamic, static and moment ratings per carriage that you can plug into a calculation; never scale those onto an LRM code. Short travel demanding crossed-roller rigidity points to LGC instead. Before ordering, tick through: set or carriage (this is a set), 12 mm rail width, standard carriage, two blocks, 445 mm rail, 10 mm end offset, preload C medium with its firmer feel, accuracy H high, top-mount holes. Two further notes: 445 mm sits well short of the 1005 mm catalogue maximum for size 12, so the same rail can serve a longer stroke if the machine grows, and only four carriage-only SKUs exist across the listing - if this rail might ever need a spare block, order it early.
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 LRM12N2X445S10CH FAQ
From the code and catalogue: rail width 12 mm, rail length 445 mm, two standard carriages, 10 mm end-hole offset, preload C (medium), accuracy H (high), top-mount rail, plain finish. Fixing: M3 screws at 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminum, into a ground or finish-milled face. Lubrication: Kyodo Yushi PS No. 2 pre-filled, re-greased every 100 km of travel or every 3 to 6 months. Environment: 80 C ambient maximum, brief excursions to 100 C. What cannot be stated: any load, moment or running-parallelism figure - LRM publishes none, and we confirm the real numbers for this model through the RFQ.
Start from the ratings, because only one series has them. LSH publishes dynamic, static and moment ratings for each carriage, so a sizing calculation can be written down and defended; LRM, including this 445 mm twin-block set, publishes none, which is why its selection ends with a confirmed per-model figure from us. Pick LRM when the envelope is small, the duty is light and smoothness matters more than a number on a datasheet; pick LSH when the load is real or hangs off an arm. If the run is short and crossed rollers would stiffen it, compare LGC too.
