Airtac LRM Miniature Linear Guide LRM12L2X470S10APT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X470S10APT 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 LRM12L2X470S10APT
This LRM12L2X470S10APT set pairs a 470 mm, 12 mm wide stainless rail with two long carriages at precision (P) grade, and the trailing T puts the fixing holes to work from below. Machine the mounting seats, offer the rail up from underneath, clamp it, and the top face stays completely clear - nothing for swarf or spilled media to catch on, and no screw heads beside the seal strip.
A long carriage engages more recirculating balls than the standard body and lengthens the effective bearing span, which helps any load that wants to tip the carriage as it travels. The ISO 3290 G10 grade applies to the balls; the double-lip seal and outer cover handle oil retention and dust exclusion. Keep the ambient under 80 C, with peaks of at most 100 C. Load and moment ratings do not appear in the LRM catalogue - tell us this model number and we will confirm the figures for you before ordering.

Where the Airtac LRM Miniature Linear Guide LRM12L2X470S10APT Is Used
Machine-vision camera rail
A camera sliding along a production line on a hidden underside-mounted rail keeps the optical axis clean, with no fasteners protruding into the field of view or the debris path.
Connector durability test sled
A sled that cycles a cable-and-connector assembly back and forth runs on a light-duty miniature guide, where the 470 mm stroke covers a realistic flexing length in a small footprint.
Labelling head slide
A print-and-apply labelling head on a compact packaging machine travels on two long carriages, spreading the overhanging head load and keeping the guide flush beneath the frame.
Is the Airtac LRM Miniature Linear Guide LRM12L2X470S10APT the Right Guide?
An underslung rail does not change the sizing logic: LRM gives you no published load figures, so anything with meaningful weight or an overhang belongs on LSH, where dynamic, static and moment ratings are tabulated per carriage. Short-travel work that needs crossed-roller stiffness points to LGC instead. Match list: set form, 12 mm rail, L-length carriage, two on one rail, 470 mm, preload A, P accuracy, bottom-mount. Ask us to confirm the load and moment figures for this model before you commit 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 LRM12L2X470S10APT FAQ
Rail width 12 mm, rail length 470 mm, two long carriages, preload A (none), precision accuracy grade P, bottom-mount fixing. Mounting screws: M2 torque 58.8 N.cm into steel, 39.2 N.cm into cast iron, 29.4 N.cm into aluminium; M3 torque 196 N.cm, 127 N.cm and 98 N.cm into the same materials. Ambient temperature limit is 80 C with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months. Basic dynamic, static and moment ratings are not published for LRM - we confirm them per model via RFQ.
A pre-assembled, pre-greased set: the 470 mm stainless rail and both precision-grade long carriages on it, drilled for underside clamping. It is not a carriage-only item and needs no pairing code. One planning note: AirTAC offers carriages separately in only a few configurations, so if you expect to replace a carriage in service, order a spare set or ask us about a carriage-only option - and use a dummy rail when fitting it, since quick or angled insertion can still drop balls despite the retention design.
