Airtac LRM Miniature Linear Guide LRM12L1X495S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X495S10AH 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 LRM12L1X495S10AH
LRM12L1X495S10AH trades location stiffness for glide: the A in the code means no preload, so the single long carriage runs with the least drag the series can offer, over a 495 mm stainless rail 12 mm wide, at high (H) accuracy with top-mount fixing. At 495 mm this rail sits close to the 1005 mm full length AirTAC lists for size 12, giving generous travel in one piece without moving to the spliced two-section format used for longer runs (which is limited to H accuracy in any case).
Inside the long carriage, Japanese-made ISO 3290 G10 balls recirculate in the shared LRM rail profile - the grade describes the balls only - wiped by a double-lip seal and sheltered by an outer cover. The 80 C ambient limit (transient peaks to 100 C) is the one environmental figure the catalogue publishes, and it is a real constraint next to an oven door or a lamp housing. With no preload the carriage can be nudged by hand, so on an inclined mount hold it during handling; the manufacturer warns it can slide off under its own weight. Load and moment ratings are not published for LRM; we will confirm them for this model number before you commit.

Where the Airtac LRM Miniature Linear Guide LRM12L1X495S10AH Is Used
Low-drag camera rail for microscope inspection
With no preload, the long carriage glides by hand under a PCB inspection microscope, letting an operator sweep the 495 mm travel with two fingers and stop exactly where the defect sits.
Flex-cycle test sled for flat cables
A reciprocating sled that bends a flat flexible cable back and forth runs on the free-rolling A-preload carriage; log distance travelled, because the 100 km re-grease mark arrives before three calendar months pass on a fast rig.
Gate guide in a small-parts sorter
A lightweight sorting gate beneath a parts chute slides on the 495 mm rail, where the stainless rail and sealed, covered carriage tolerate the dust shed by moulded plastic parts.
Is the Airtac LRM Miniature Linear Guide LRM12L1X495S10AH the Right Guide?
Because AirTAC publishes no load or moment ratings for LRM, sizing is a conversation rather than a table lookup: send the payload, its overhang and the duty cycle, and we will confirm the figures for this model. If the numbers turn out to be beyond a miniature guide, LSH is the step up - it publishes dynamic, static and moment ratings per carriage that you can design against - and LGC is the sideways step when travel is short and crossed-roller rigidity matters more than low friction. Checklist for LRM12L1X495S10AH: complete set, 12 mm rail, long carriage, one carriage, 495 mm length, preload A (none), accuracy H, top-mount fixing, 10 mm end-hole offset. One budgeting note: across our LRM range the price is driven almost entirely by rail length and carriage count rather than rail width, so trimming travel length is the first cost lever.
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 LRM12L1X495S10AH FAQ
Rail width 12 mm; rail length 495 mm; one long carriage; preload A (none); accuracy H (high); top-mount fixing; 10 mm end-hole offset. It ships greased with Kyodo Yushi PS No. 2 and is topped up through the rear lubrication hole every 100 km of travel or every 3 to 6 months. Ambient temperature must not exceed 80 C, with transient peaks to 100 C. Screw torques: M2, 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3, 196, 127 and 98 N.cm. Load and moment ratings are not published for the LRM series, so we confirm them for this exact model on enquiry.
Decide on ratings, not on size. LRM publishes no dynamic, static or moment load figures, so it is the choice when the envelope is tight and the duty is light precision positioning, with capacity confirmed per model before ordering. LSH is the step up when the load is heavy or overhung and you need published per-carriage ratings to design against. LGC fits short travels that demand crossed-roller rigidity. If you stay with this 495 mm A-preload set, remember the carriage can slide on an inclined rail under its own weight - hold it during installation and never strike or drop the rail, since accuracy can suffer with no visible damage.
