Airtac LRM Miniature Linear Guide LRM12L1X495S10CHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X495S10CHT 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 LRM12L1X495S10CHT
This is the same 12 mm, 495 mm stainless-steel rail and single long carriage as the plain LRM12L1X495S10CH, but the trailing T in LRM12L1X495S10CHT changes the installation: the rail clamps from beneath, leaving the top face clean so nothing obstructs the carriage sweep. It is the version to pick when screw heads cannot sit proud of the running surface.
Design points for this build: the long carriage spreads contact over more recirculating balls, preload C (medium) removes internal clearance for a firm slide, and the rolling elements are Japanese-made ISO 3290 G10 balls - a ball grade, not a standard the whole guide is certified to. A double-lip seal and an outer cover guard the raceway from oil loss and debris, and the guide must run in an ambient of 80 C or less. The catalogue publishes no load or moment rating for LRM, so we confirm those numbers for this exact bottom-mount configuration when you enquire.

Where the Airtac LRM Miniature Linear Guide LRM12L1X495S10CHT Is Used
Under-deck shuttle for small wafers
Where a clean top surface matters on a semiconductor bench, the bottom-mount rail hides beneath a compact wafer shuttle deck, with no screw heads exposed to the particles above.
Benchtop adhesive-dispensing axis
A low-profile dispensing gantry for electronics adhesive benefits from the long carriage, whose extended span resists the pitching of a head mounted off the rail centreline.
Connector test fixture slide
A fixture sliding a connector stack into a test head uses preload C for zero lost motion, so repeated mating cycles stay aligned with the socket.
Is the Airtac LRM Miniature Linear Guide LRM12L1X495S10CHT the Right Guide?
A bottom-mount rail earns its keep inside a housing, under a worktable or anywhere the fixing screws must be invisible from above - verify that you can actually reach underneath before ordering it. If the load grows beyond light duty, or the part cantilevers, move to LSH, which publishes per-carriage dynamic, static and moment ratings; LRM does not, and we confirm its figures per model. Short travels that need crossed-roller stiffness point to LGC instead. Tick the list: set or carriage, 12 mm width, long block, one carriage, preload C (rigid but less forgiving than A), accuracy H, bottom-mount direction, and our load confirmation.
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 LRM12L1X495S10CHT FAQ
Published facts: 12 mm stainless rail, 495 mm long, one long carriage, preload C (medium), H accuracy, bottom-mount rail. Tighten M3 screws to 196 N.cm in steel, 127 N.cm in cast iron and 98 N.cm in aluminium. Keep the ambient at 80 C maximum with 100 C peaks, and re-grease every 100 km of travel or every 3 to 6 months. Basic dynamic load, static load, moment ratings, running parallelism and speed limits are not published for LRM - send an RFQ and we confirm them for this model.
You receive one matched complete set: the 495 mm rail and one long carriage, pre-filled at the factory with Kyodo Yushi PS No. 2 grease. The ball-retention design holds the balls during normal handling, but tilting the carriage onto the rail or swapping it hastily can still drop them - the manufacturer suggests a dummy rail if you expect frequent carriage changes, and we stock only a handful of carriage-only SKUs, so a swap usually means a special order. Never dismantle the carriage or strike the rail; damage can be invisible and still cost accuracy.
