Airtac LRM Miniature Linear Guide LRM12N2X495S10AHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X495S10AHT 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 LRM12N2X495S10AHT
In this code the trailing T changes one thing from LRM12N2X495S10AH: the 495 mm, 12 mm wide stainless rail mounts from below, its top face left unbroken for the carriage sweep - handy where the design cannot expose screw heads or a tool cannot work over the rail. Two standard-length carriages ride the rail on recirculating balls, and the box holds rail plus carriages only, with no fixing screws included.
With no preload (grade A) and high accuracy H, the set runs freely while still tracking straight - but remember the mounting surface does the accuracy work, so the seat should be ground or finish-milled to the catalogue's per-size surface requirements. Handling notes from the manufacturer: the ball-retention design helps, yet an angled or hurried carriage insertion can still shed balls, and on an inclined rail a carriage can slide off under its own weight, so keep a hand on it. The balls are Japanese-made ISO 3290 G10 grade; the seals are double-lip, and the outer cover hides the screws. The ambient ceiling is 80 C with 100 C transient peaks. Load and moment ratings are confirmed per model - ask via the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X495S10AHT Is Used
Shop-floor measuring fixture for micro-turned parts
A bench gauge that slides an indicator or camera along micro-machined shafts: bottom-mounting keeps the gauge top clear for the part and probe, and grade H keeps the slide tracking true.
Thermal print-head slide in a lab label printer
Carrying the thermal print head along a 495 mm print path; mount the drive away from the head, since the ambient ceiling for LRM is 80 C with transient peaks of 100 C.
Glovebox sample-transfer stage
Inside a sealed glovebox, fastening the rail from below through a baseplate is far easier than reaching over it with gauntlets, and the stainless rail suits a wiped-down environment between batches.
Is the Airtac LRM Miniature Linear Guide LRM12N2X495S10AHT the Right Guide?
For anything with a serious or overhung load, LSH is the honest answer: its catalogue lists basic dynamic, static and moment ratings per carriage, while LRM publishes none, so capacity here is always confirmed with us before ordering. Short travel where crossed-roller rigidity beats ball smoothness points to LGC. Match checklist: complete set (rail included), 12 mm rail width, standard carriage, two blocks, 495 mm rail, preload A, accuracy H, bottom-mount rail. Two practical notes: size 12 is where our stock is deepest - 924 of 988 stocked LRM sets - so this rail length ships quickly; and if a carriage is ever damaged, carriage-only replacements are thin (we stock just four such SKUs), so it pays to order a spare alongside the original set.
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 LRM12N2X495S10AHT FAQ
12 mm rail width, 495 mm rail length, two standard-length carriages, no preload (grade A), high accuracy (grade H), bottom-mount rail with a 10 mm end-hole offset. M3 screws torque to 196 N.cm into steel, 127 N.cm into cast iron and 98 N.cm into aluminium. The ambient temperature ceiling is 80 C with transient peaks of 100 C, and re-lubrication falls due every 100 km of travel or every 3 to 6 months. AirTAC publishes no basic dynamic, static or moment rating for LRM, so load capacity is confirmed per model - ask us.
You receive the 495 mm, 12 mm wide stainless rail and two standard-length carriages - no fixing screws and no end caps. Handling deserves care: the ball-retention design keeps balls captive in normal use, but fitting a carriage at an angle or swapping it hastily can still drop a ball, so a dummy rail helps for field swaps - and carriage-only replacements are thin on our shelf (four SKUs stocked), so consider a spare with the original order. On an inclined rail the carriage can also slide off under its own weight, so keep a hand on it while handling.
