Airtac LRM Miniature Linear Guide LRM12N2X495S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X495S10CP 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 LRM12N2X495S10CP
This AirTAC LRM12N2X495S10CP is a complete miniature linear guide set: a 495 mm stainless-steel rail, 12 mm wide, carrying two standard-length recirculating-ball carriages with the mounting holes offset 10 mm from each end. Two blocks on one rail resist tipping along the direction of travel, which is why twin-carriage sets are the usual choice for a compact positioning axis. The set arrives assembled and ready to bolt to a ground or finish-milled seat, top-mount style, with fixing from above.
Preload C is the medium grade: it removes play for the firmest travel of the three LRM grades, at the cost of higher drag and a less forgiving attitude to mounting-surface error. The carriages ride on ISO 3290 G10 Japanese balls - the grade applies to the balls alone, not to the guide assembly - held by a ball-retention design that reduces, but does not eliminate, dropped balls during handling. A double-lip seal scrapes oil and excludes dust, and an outer cover shields the seal strip and screw heads. Carriages share one common LRM rail profile, so block types interchange on the same rail. Ambient temperature must stay at or below 80 C, with transient peaks to 100 C. Load and moment ratings are not published for LRM; we confirm them for this exact model when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X495S10CP Is Used
Semiconductor pick-and-place head
A twin-block set on one 495 mm rail resists tipping along the travel axis, and medium preload removes play for repeatable component placement inside a compact head.
Optical inspection camera stage
Precision-grade travel with twin carriages gives a smooth scan for a small camera or sensor on an inspection bench; keep lamp heat under the 80 C ambient limit.
Miniature dispensing nozzle axis
Preload C stiffens the carriage against the tipping effect of an offset nozzle, while the double-lip seal and outer cover keep fluid mist and dust out of the raceway.
Is the Airtac LRM Miniature Linear Guide LRM12N2X495S10CP the Right Guide?
When the load is substantial or overhung, step up to LSH instead: that larger series publishes dynamic, static and moment ratings per carriage, giving you real numbers to size against, which LRM does not offer. If travel is short and the priority is crossed-roller rigidity, LGC is the better cross-over. For this set itself: two standard carriages on a 495 mm rail, preload C trades a little running drag for the least play, accuracy P is the tighter grade, and the top-mount rail bolts down from above. Mind the maintenance angle too - at a 200 mm stroke cycling once a second, the 100 km re-grease point arrives in roughly three weeks of continuous running, so distance rather than the calendar sets the schedule. Replacing a single carriage rather than buying a set? Carriage-only codes carry a pairing letter and our carriage-only stock is thin - confirm the load and moment figures with us before committing.
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 LRM12N2X495S10CP FAQ
The set uses a 12 mm wide, 495 mm long stainless rail in top-mount form, with two standard-length carriages, medium preload (C) and precision accuracy (P). Fixing screws: M2 torque to 58.8 N.cm in steel, 39.2 in cast iron, 29.4 in aluminium; M3 to 196, 127 and 98 N.cm respectively. Carriages ship greased with Kyodo Yushi PS No. 2 and need re-greasing every 100 km of travel or every 3 to 6 months, through the hole at the carriage rear. Ambient temperature must stay at or below 80 C, with peaks to 100 C. Basic dynamic, static and moment ratings are not published for LRM; we confirm them for this model before you order.
Move to LSH when the load is substantial or cantilevered. LSH is a larger series whose catalogue publishes dynamic, static and moment ratings per carriage, so you can run a real sizing calculation - LRM offers no published figures, which is why we confirm the load for each LRM model individually. If the stroke is short and crossed-roller rigidity is what you need, LGC is the alternative. Stay with this LRM12 set for compact, light-duty positioning where a 12 mm rail and twin precision blocks fit the envelope and smoothness matters.
