Airtac LRM Miniature Linear Guide LRM12L1X470S10CPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X470S10CPT 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 LRM12L1X470S10CPT
LRM12L1X470S10CPT is the rigid, less forgiving choice in the LRM12 family: a 470 mm long, 12 mm wide stainless-steel rail carrying one long carriage, with medium preload (C), precision (P) accuracy and bottom-mount (T) rail fixing so the clamp screws are worked from underneath. Medium preload removes the clearance a free-running carriage has, which holds position under vibration and direction changes at the cost of slightly higher drag. The carriage arrives mounted on the rail, pre-filled with grease, ready to be bolted down from below.
Like the rest of the series it runs Japanese ISO 3290 G10 balls - the grade belongs to the balls themselves - inside the common-rail profile, behind a double-lip seal and an outer cover that keeps chips off the seal strip. One caution is worth planning for: the ball-retention design helps during handling, but angling the carriage onto the rail or swapping it hastily can still drop balls, so keep a dummy rail at hand if the carriage will ever come off. Ambient temperature is capped at 80 C, with momentary peaks to 100 C. Load and moment figures are absent from the published data because AirTAC publishes none for LRM; send the RFQ and we confirm them for this model.

Where the Airtac LRM Miniature Linear Guide LRM12L1X470S10CPT Is Used
Miniature pick-and-place head guide
A long carriage gives a small vacuum pick-and-place head a longer bearing span over a 470 mm axis, steadying the head as it reaches past the guide centreline.
High-cycle sample shuttle in an electronics lab
A shuttle cycling a 200 mm stroke once per second covers 100 km in roughly three weeks of continuous running - the point where the LRM re-grease interval (every 100 km or 3 to 6 months) binds before the calendar does.
Sample shuttle in a microplate autosampler
A small shuttle carries microplates between wash and read stations on a 470 mm axis; the medium preload keeps it from drifting when it stops and starts.
Is the Airtac LRM Miniature Linear Guide LRM12L1X470S10CPT the Right Guide?
Sizing starts from the fact that LRM carries no published dynamic, static or moment ratings. Where a real load calculation is needed - a heavy head or a long overhang - move to LSH and use its per-carriage dynamic, static and moment tables; where travel is short and you want crossed-roller stiffness rather than ball smoothness, pick LGC instead. For this exact code check: set form (rail included), 12 mm rail width, long carriage, one carriage, 470 mm rail, preload C (firm, slightly stiffer running), precision accuracy, bottom-mount fixing, plus the 10 mm end-hole offset. Whatever the payload, confirm the load and moment figures with us for this model before committing. If your layout can spare the space, note that a second carriage on the same rail resists tipping along the travel - a common upgrade on this kind of axis.
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 LRM12L1X470S10CPT FAQ
A 12 mm wide, 470 mm long stainless rail with one long carriage, medium preload (C), precision accuracy (P), bottom-mount (T) fixing and a 10 mm end-hole offset. Greasing follows Kyodo Yushi PS No. 2, topped up through the rear lubrication hole every 100 km of travel or 3 to 6 months. Keep ambient temperature at or below 80 C, peaks 100 C. Tighten M2 screws to 58.8 N.cm in steel, 39.2 in cast iron, 29.4 in aluminium; M3 to 196, 127 and 98 N.cm. Load and moment ratings are deliberately absent from our data because AirTAC publishes none for LRM - we confirm them per model on enquiry.
Yes - the X in the code marks a complete set: rail and one long carriage, mounted and greased together as delivered. A spare carriage is a different matter: carriage-only LRM codes are scarce on our side, so most spares are special orders, and a carriage-only code carries a pairing letter (A to E) that must match the rail it runs on. Handling matters too - the ball-retention design limits, but does not guarantee against, dropped balls if the carriage is angled onto the rail, so a dummy rail is the careful way to swap carriages in the field.
