Airtac LRM Miniature Linear Guide LRM12N2X445S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X445S10AH 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 LRM12N2X445S10AH
LRM12N2X445S10AH is a full AirTAC LRM miniature guide set: a 445 mm rail, 12 mm wide and stainless throughout, delivered with a pair of standard-length ball carriages seated on it and a 10 mm offset between the rail ends and the first screw holes. Top-mount fixing, so the fasteners come down through the rail face into the prepared base.
Two carriages on one rail do more than share the duty - they resist tipping along the direction of travel, which steadies any bracket that overhangs the blocks. Preload A keeps the running clearance interference-free and accuracy grade H is the standard high grade offered on LRM. Worth knowing before you build: the ball-retention design helps but does not guarantee against dropped balls if a carriage is angled onto the rail or swapped hastily, so plan a dummy rail for any field change. Japanese ISO 3290 G10 balls sit in the raceways (that grade covers the balls alone), under a double-lip seal and an outer cover, on the common LRM rail profile. Ambient stays at or below 80 C with momentary peaks to 100 C. Load and moment ratings are absent from the LRM catalogue; we confirm them for this part number on request.

Where the Airtac LRM Miniature Linear Guide LRM12N2X445S10AH Is Used
Glue-dispensing bridge over a PCB
A small dispensing gantry crossing a populated circuit board, where the dual-carriage arrangement steadies the dispense head against pitch near the ends of travel.
Vial lane actuator on a packaging line
A light-duty lane actuator sorting vials in a packaging hall, where the stainless rail tolerates the ambient and the outer cover keeps debris off the seal strip.
Bond-wire feed slide on a wire bonder
A short feed slide guiding bond wire on a miniature assembly machine, where straight, repeatable travel matters far more than heavy capacity.
Is the Airtac LRM Miniature Linear Guide LRM12N2X445S10AH the Right Guide?
Size across series before anything else: LSH is the step up when loads are real or overhung, because it publishes per-carriage dynamic, static and moment ratings, and LGC covers short travels where crossed-roller stiffness is the priority. Then verify this build line by line: complete set, 12 mm rail width, standard carriage length, two carriages, 445 mm of rail, preload A whose trade-off is effortless running traded against visible internal play, accuracy H, top-mount rail, and a per-model load figure we confirm with you. Price behaves the same way: stocked LRM sets run from about $66 to $831 almost entirely on rail length and carriage count, not rail size, so trimming travel is the lever that trims cost. Replacing a single block requires its pairing letter to match the rail.
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 LRM12N2X445S10AH FAQ
A 12 mm wide rail of 445 mm, two standard carriages, preload A (none), accuracy H (high), top-mount rail, 10 mm end-hole offset. Torque figures are 196 N.cm for M3 screws into steel, 127 N.cm into cast iron and 98 N.cm into aluminium; M2 equivalents are 58.8, 39.2 and 29.4 N.cm. The ambient limit is 80 C with transient peaks to 100 C, and re-greasing falls due every 100 km of travel or every 3 to 6 months, never mixing lubricant types. Load and moment ratings are not published for the LRM series; we confirm the values for this exact model.
LRM is the miniature end of the range, picked for envelope, precision and smoothness in light-duty positioning. LSH is the larger series and the right move when sizing against published numbers is central to your design: it lists basic dynamic, static and moment ratings per carriage, and LRM lists none of those, which is why we confirm LRM figures per model. Short travel needing crossed-roller rigidity points to LGC instead. Tell us the duty and the stroke and we will steer you to the right series before you order.
