Airtac LRM Miniature Linear Guide LRM12L1X470S10CH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X470S10CH 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 LRM12L1X470S10CH
LRM12L1X470S10CH is the stiffer sibling in this group: a complete set with a 12 mm wide, 470 mm long stainless-steel rail, one long recirculating-ball carriage, medium preload C and high accuracy H, fixed from the top with mounting holes 10 mm in from each rail end.
Preload C removes more internal clearance than the light B grade, so the carriage feels tighter in the hand and deflects less under small side loads. The trade-off is higher drag and a less forgiving fit, which is why the catalogue calls for ground or finish-milled mounting surfaces before the rated travel accuracy means anything. Either side of the rail can be the datum face; if a second carriage is added later, keep the datum on the same side for all of them. The build includes retained Japanese-made ISO 3290 G10 balls (balls only), a double-lip seal and an outer cover, and the ambient must stay at or below 80 C. Two planning facts: the 100 km re-grease interval binds by distance, not calendar - a 200 mm stroke at one cycle per second reaches it in about three weeks of continuous running - and, as everywhere in LRM, load and moment ratings are not published, so we confirm the figure for this code when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X470S10CH Is Used
High-cycle lab dispensing head
A pipetting head cycling short strokes all day; because 100 km of travel arrives in weeks at one cycle per second, plan greasing by distance, not by calendar.
Connector press slide
A light pressing slide seating small connectors in an electronics assembly cell, where medium preload C keeps the tooling steady at the end of stroke.
Micro-stage retrofit
Replacing a worn slide in an aging positioning table; the long carriage and the series' common-rail design keep the mechanical upgrade simple.
Is the Airtac LRM Miniature Linear Guide LRM12L1X470S10CH the Right Guide?
Start from the checklist: complete-set form, 12 mm rail width, long carriage, single block, 470 mm rail, preload C and its trade-off, accuracy H, top-mount direction. If the mechanism carries a real load or a cantilever, size up to LSH instead - its catalogue gives dynamic, static and moment ratings per carriage, numbers LRM does not publish. For short travel with crossed-roller rigidity, LGC is the closer match. On cost: across this listing, price climbs with rail length and carriage count far more than with rail width, and the 12 mm size is the most broadly listed in the range, so an uncommon length like 470 mm is easy to match. Confirm the load rating with us before you commit.
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 LRM12L1X470S10CH FAQ
A complete guide set: 12 mm wide stainless-steel rail, 470 mm long, one long carriage, medium preload C, high accuracy H, top-mount fixing, mounting holes 10 mm from the rail ends. Torque M3 screws to 196 N.cm in steel, 127 N.cm in cast iron, 98 N.cm in aluminium (M2: 58.8 / 39.2 / 29.4 N.cm). Ambient temperature limit is 80 C, briefly peaking to 100 C; re-grease every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them for this specific model on request.
It is a complete set: the 470 mm rail arrives with the long carriage already fitted and pre-greased with Kyodo Yushi PS No. 2. No pairing code is involved - pairing letters apply only to carriage-only codes such as LRM12BK-..., where a rail and a replacement carriage must share the same letter, and carriage-only listings are few, so most replacement carriages are ordered specially.
