Airtac LRM Miniature Linear Guide LRM12L1X495S10APT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X495S10APT 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 LRM12L1X495S10APT
LRM12L1X495S10APT combines two specification choices in one set: precision (P) accuracy and bottom-mount rail fixing. You receive one 12 mm wide, 495 mm long stainless rail drilled for M3 screws in its base, and one long recirculating-ball carriage riding it. Preload code A: the factory fits no interference, so travel stays light. Nothing pneumatic is involved - this is a purely mechanical sliding guide.
The pairing of P grade with underside fixing suits instruments where the measuring axis is concealed beneath a plate: think a wafer-transport drawer or a metrology slide under a granite table, where the top surface must stay unbroken. Since only one carriage rides this rail, align its datum face deliberately; if you ever add a second block on the same rail, put both datum references on the same side to preserve running accuracy. The carriage carries ISO 3290 G10 Japanese balls (a ball grade, not an assembly standard), held by ball retention, wiped by a double-lip seal under an outer cover. Keep the environment at 80 C or cooler, peaks 100 C. AirTAC publishes no load or moment ratings for LRM, so we confirm them for this model before you order - use the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X495S10APT Is Used
Cable-and-harness test traverser
A bench tester flexing wiring looms along a 495 mm stroke benefits from precision travel so the connector gauge stays aligned; underside fixing keeps the rail's top clear of the harness.
Desktop marking and plotting gantry
A small plotting or dot-peen marking axis over paperwork or small parts uses the long carriage to resist pen-head tipping, with P grade holding the line path true.
Microscope specimen drawer
A slide-in specimen drawer beneath a laboratory microscope conceals the rail under the drawer floor; bottom-mount screws and precision travel suit both the layout and the optics.
Is the Airtac LRM Miniature Linear Guide LRM12L1X495S10APT the Right Guide?
Three-way check before you buy. Heavy or overhung loads: go to LSH, the series with published per-carriage dynamic, static and moment ratings you can calculate against - LRM offers no such table, which is why we confirm figures individually. Short travel, maximum stiffness: LGC's crossed rollers beat ball guides for rigidity over a short stroke. Light-duty, space-limited, precision-travel: this LRM set.
Specification to confirm: complete set form; 12 mm rail width; long (L) carriage; one block; 495 mm rail length; preload A (freest motion, least rigid); accuracy P; bottom-mount direction; no pairing code required. A practical note on carriage swaps: ball retention helps, but fitting a carriage at an angle or in a hurry can still drop balls, and with only four carriage-only SKUs stocked, field replacements usually mean a special order - keep a dummy rail if you swap often. Confirm the load rating for this exact model with us before design freeze.
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 LRM12L1X495S10APT FAQ
Published and quotable: 12 mm rail width, 495 mm rail length, one long (L) carriage, preload A (none), accuracy P (precision), bottom-mount mounting direction, 80 C ambient limit with 100 C transient peaks, re-grease interval of 100 km of travel or 3 to 6 months, M3 screw torque of 196 N.cm into steel, 127 into cast iron and 98 into aluminium. Not published by AirTAC for LRM: basic dynamic and static load ratings, moment ratings, running-parallelism tolerance and maximum speed. We confirm the load figures for this specific model through the RFQ before you order.
Prepare the mating surface by grinding or finish milling - travel accuracy depends on it - and observe the catalogue's edge-distance and shoulder-height rows as a set, since they are listed without size assignments. The trailing T puts the screw holes in the rail's underside, so fix it upward into the deck. Either side of the rail can serve as the datum face; whatever you choose, mark it and keep any future carriages' datums on the same side. Finally, never strike the rail during fitting - invisible damage can still degrade accuracy and service life.
