Airtac LRM Miniature Linear Guide LRM12L1X220S10CP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X220S10CP 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 LRM12L1X220S10CP
LRM12L1X220S10CP arrives as a matched pair of parts from AirTAC: a 220 mm stainless rail, 12 mm across, closed at each end with 10 mm hole offsets, and one long (L) carriage running on it. This is a top-mount set - the screws go down through the rail into your base plate. The carriage ships pre-filled with Kyodo Yushi PS No. 2 grease.
The P in the code is the precision accuracy grade, a step tighter than H, which earns its keep when carriages must track consistently or when the driven axis feeds a measuring function. Preload C biases the balls for minimal play; expect a touch more rolling resistance than a grade-A set. Japanese ISO 3290 G10 balls sit inside the circuit - that ball grade is the only standards claim here, and it covers the balls alone. A double-lip seal and outer cover protect the raceways, and the guide tolerates 80 C ambient with 100 C transients. Load and moment ratings are not published for this series; tell us your duty and we will confirm the figure for this model before you order.

Where the Airtac LRM Miniature Linear Guide LRM12L1X220S10CP Is Used
Electronics pick-and-place head
A lightweight placement head stepping across component reels; the long carriage damps the tipping that a head arm can introduce.
Laser module alignment stage
Fine positioning of an optics carrier where P-grade consistency matters between repeated approaches.
Automated optical inspection travel
An AOI camera riding a 220 mm rail over a PCB panel, returning to datum between panels.
Is the Airtac LRM Miniature Linear Guide LRM12L1X220S10CP the Right Guide?
Rail length, not rail width, drives most of the price spread across our stocked sets, so trimming a few millimetres of travel often beats downsizing the guide. Availability is strongest at size 12 - 924 of our stocked LRM sets are 12 mm - and long carriages are stocked just as deeply as standard ones, so this L-specification carries no availability penalty. If your load is heavy or overhung, move to LSH, which publishes dynamic, static and moment ratings per carriage for proper sizing; if the travel is short and you need crossed-roller stiffness, LGC is the better cross-grade. Check: complete set, 12 mm rail, long carriage, one per rail, 220 mm length, preload C, accuracy P, top-mount, and confirm loads with us via RFQ.
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 LRM12L1X220S10CP FAQ
Choose LRM when the priority is a 12 mm envelope, smooth light-duty motion and a compact footprint, accepting that its datasheet publishes no dynamic, static or moment ratings - we confirm capacity for the specific model on request. Choose LSH when the load is substantial or cantilevered and you need published per-carriage ratings to size against; it is a larger series with a fuller load table. For short travels where crossed-roller rigidity matters more than travel length, LGC is the third option.
One 12 mm wide, 220 mm long stainless rail with 10 mm end-offset holes and one long carriage fitted to it - a complete set, top-mounted, preload C, precision P grade. M3 screws take 196 N.cm into steel, 127 into cast iron, 98 into aluminium; M2 screws 58.8, 39.2 and 29.4 N.cm. Re-grease every 100 km of travel or every 3 to 6 months through the rear lubrication hole, never mixing grease types, and keep the ambient at or below 80 C with peaks to 100 C. Dynamic, static and moment load ratings are not published for LRM; we confirm them per model when you ask.
