Airtac LRM Miniature Linear Guide LRM12N2X470S10CHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X470S10CHT 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 LRM12N2X470S10CHT
This is one of the longer single-piece layouts in the LRM12 selection: the catalogue tops the size 12 rail out at 1005 mm, and at 470 mm this set delivers close to half of that in one piece, with two standard carriages sharing the run. The trailing T specifies bottom-mount fixing, so the rail is clamped through its base and the machine builder can keep the top face uninterrupted. The rail is stainless steel; the carriages run on recirculating balls and arrive pre-greased with Kyodo Yushi PS No. 2.
Two carriages on one rail do more than double the mounting points - they resist tipping along the direction of travel, which matters when the load sits above the slide or leans over its edge. The C preload here is the firm grade: minimal play under changing load direction, at the cost of sensitivity to imperfect mounting surfaces, so plan on a ground or finish-milled seat. The ball circuit uses ISO 3290 G10 grade balls - the grade covers the balls only - retained in the carriage, scraped by a double-lip seal and shielded by an outer cover. Keep ambient temperature at or below 80 C with peaks no higher than 100 C. LRM carries no published load or moment ratings, so confirm the capacity of this exact set with us via the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X470S10CHT Is Used
Semiconductor die handler
A small die-pick head traverses a wafer tray on a twin-carriage slide; the two blocks resist tipping as the head lifts and lowers parts at the rail edge.
Wafer inspection fixture
In a cleanroom inspection bench, a covered miniature rail carries a wafer stage under a microscope, with bottom fixing leaving the top surface clear for the chuck.
Packaging-line pusher
A light pusher finger on a small packaging machine is guided on a twin-carriage slide, where the firm C preload keeps the finger square as it kicks product off a belt.
Is the Airtac LRM Miniature Linear Guide LRM12N2X470S10CHT the Right Guide?
Before locking this code in, weigh rigidity against fit-up. C preload rewards careful machining of the seat and punishes a bowed plate with tight spots along the 470 mm; if your base is likely to be less than perfect, A or B preload may run more freely. If the load is heavy, overhung or otherwise beyond what a miniature guide should be asked to do, size the axis in LSH instead - that series publishes basic dynamic, static and moment ratings per carriage, the numbers LRM withholds - or, for short travels where crossed-roller stiffness is the priority, go to LGC. Then confirm every element of the order with us: complete-set form, 12 mm rail width, standard carriage length, two carriages, 470 mm rail, C preload, H accuracy, bottom-mount direction, and the load rating for this specific configuration, which we check per model. Staying at 12 mm rail width also pays off in range: the overwhelming majority of listed LRM sets are size 12, and long-carriage versions are carried as widely as standard ones, so a later switch to a long carriage is easy to source.
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 LRM12N2X470S10CHT FAQ
Rail: 12 mm wide, 470 mm long, bottom-mount fixing. Carriages: two, standard length, with preload grade C (medium) and accuracy grade H (high). Assembly torques for the mounting screws: M2 - 58.8 N.cm steel, 39.2 N.cm cast iron, 29.4 N.cm aluminium; M3 - 196 N.cm steel, 127 N.cm cast iron, 98 N.cm aluminium. Environment: no more than 80 C ambient, transient peaks to 100 C. Maintenance: re-grease every 100 km of travel or every 3-6 months. What you will not find published is a load or moment rating - LRM has none - so we confirm the figures for this exact model when you contact us.
Choose LRM when the driving reasons are a 12 mm envelope, smooth light-duty travel and a long slender rail like this 470 mm one. Choose LSH when you need published engineering data to size against: it lists basic dynamic load, static load and moment ratings per carriage, none of which exist for LRM. A practical habit is to shortlist LRM for the layout, then send us the actual load, moment and duty of the application - we confirm what this specific LRM set can take, or recommend LSH if the numbers say so. For short travels where rigidity matters more than reach, LGC with crossed rollers is the other alternative.
