Airtac LRM Miniature Linear Guide LRM12L1X495S10AHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X495S10AHT 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 LRM12L1X495S10AHT
LRM12L1X495S10AHT is a complete AirTAC LRM miniature guide: one 495 mm stainless rail, 12 mm wide, carrying a single long (L) ball carriage. The trailing T in the code switches the fixing to bottom-mount - the screw holes sit in the base of the rail - so the guide bolts up from underneath, into your machine deck. Preload A means the manufacturer adds no interference between balls and raceway, favouring free running.
Bottom-mount pays off wherever the top of the rail is buried: a cover strip, a mating slide or a crowded deck leaves no room to reach screw heads from above, and this variant solves that. The carriage rides on ISO 3290 G10 Japanese balls (that grade describes the balls only), retained so they will not spill during routine handling, behind a double-lip seal and an outer cover. Two handling cautions worth planning around: on an inclined mounting the carriage can slide under its own weight, so hold it during fitting, and never strike the rail - damage that shortens accuracy and life is not always visible. There is no published load or moment rating for LRM; we verify the numbers for this model via the RFQ before purchase.

Where the Airtac LRM Miniature Linear Guide LRM12L1X495S10AHT Is Used
Under-bench autosampler transport
A laboratory autosampler sliding sample vials beneath a sealed work surface can only be serviced from below; bottom-mount screws make the 495 mm rail reachable without stripping the deck.
Conveyor-mounted sensor carriage
A small inspection sensor tracking along a production line bolts to the long carriage; the underside fixing keeps the rail's top face clear for guards and product flow.
Retrofit slide inside a machine base
Adding motion to an existing fixture often means working in a closed cavity; a rail you screw in from beneath, holding 80 C ambient maximum, suits that cramped retrofit reality.
Is the Airtac LRM Miniature Linear Guide LRM12L1X495S10AHT the Right Guide?
Before settling here, weigh the alternatives. For meaningful loads or an overhung mass, LSH is the honest choice - its catalogue lists dynamic, static and moment ratings per carriage, giving you real numbers to calculate with, whereas LRM leaves those to be confirmed case by case. For short travel needing crossed-roller rigidity, look at LGC. This LRM set fits light-duty, space-starved positioning where the underside is the only accessible face.
Confirm: complete set form; 12 mm rail width; long carriage; one block; 495 mm rail length; preload A (smoothest, least rigid of the three grades); accuracy H; bottom-mount direction. Mounting surfaces should be ground or finish-milled to hold travel accuracy, and the quench-edge and shoulder dimensions differ per size - quote the catalogue rows as a set rather than assuming one row for 12 mm. Ask us to confirm the load rating for this exact model before you freeze the design.
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 LRM12L1X495S10AHT FAQ
Choose LRM when the envelope is small and the duty is light; choose LSH when you need published numbers to size against, because LSH lists basic dynamic load, static load and moment ratings for each carriage while LRM publishes none - every load question on this 12 mm, 495 mm, long-carriage, bottom-mount set has to be confirmed with us per model. If travel is short and rigidity per millimetre matters most, LGC's crossed-roller construction is the third option. Getting the decision right before ordering beats swapping series after the machine is cut.
It flips the rail mounting direction to bottom-mount: the fixing holes sit in the rail's underside so you screw it up into the deck from below, instead of dropping screws into the top face. Everything else in LRM12L1X495S10AHT matches its top-mount sibling - 12 mm stainless rail, 495 mm long, one long carriage, preload A, accuracy H. Both directions are stocked, so the choice is purely about which face of your machine you can reach with a screwdriver.
