Airtac LRM Miniature Linear Guide LRM12L1X295S10APT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X295S10APT 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 LRM12L1X295S10APT
This AirTAC part number describes a factory-matched LRM miniature guide set: a 295 mm stainless-steel rail 12 mm wide, one long recirculating-ball carriage, preload code A (none), precision accuracy grade P, and bottom-mount drilling indicated by the trailing T. The carriage arrives on the rail; the set is complete as supplied.
The combination of grade P and bottom mounting points squarely at metrology-style hardware: a measuring or inspection fixture where the guide is let into a machined pocket from below, keeping the top surface clear for the workpiece, while precision grade holds travel straightness tighter than the standard H grade. Note that the 100 km re-grease interval arrives faster than it sounds - a 200 mm stroke cycling once a second covers 100 km in roughly three weeks of continuous running, so calendar time alone will not tell you when to grease. AirTAC's design features on this carriage include the double-lip seal, the outer cover over the screws and seal strip, ball retention holding the ISO 3290 G10 Japanese balls captive, and a rail profile shared across the LRM carriage family. Ambient temperature must stay at or below 80 C, briefly to 100 C. LRM load and moment ratings are not published; we confirm them per model - include this SKU in an RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X295S10APT Is Used
Gauge block inspection carriage in a QC lab
Bottom-mounted flush into a granite or steel surface plate adapter, the precision-grade rail carries a dial-indicator fixture along the 295 mm stroke for repeatable part checks.
Probe positioner on a semiconductor wafer bench
A light-touch, unpreloaded long carriage lets a technician advance a needle probe toward a test pad with minimal overshoot on the 12 mm stainless rail.
Lens turret traverse in an optical inspection machine
Grade P travel accuracy keeps the lens axis steady as the turret slides along the recessed, underside-fixed rail, so focus does not drift across the stroke.
Is the Airtac LRM Miniature Linear Guide LRM12L1X295S10APT the Right Guide?
When the load is significant or cantilevered, LSH is the honest upgrade: it publishes per-carriage dynamic, static and moment ratings, which no LRM datasheet does. For very short travels demanding crossed-roller stiffness, compare LGC. For this exact code, verify: set form (rail included), 12 mm rail width, long carriage, single carriage, 295 mm rail, preload A (freest running, least rigid), accuracy P, bottom-mount (T), and that any replacement carriage later matches this rail. Confirm the load rating with us before committing the design.
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 LRM12L1X295S10APT FAQ
One stainless-steel rail, 12 mm wide and 295 mm long, one long carriage, preload A (none), accuracy grade P (precision), bottom-mount drilling. Mounting screws: M2 at 58.8 N.cm into steel, 39.2 N.cm into cast iron, 29.4 N.cm into aluminium; M3 at 196, 127 and 98 N.cm respectively. Ambient temperature must not exceed 80 C (peaks 100 C). Re-grease after every 100 km of travel or every 3 to 6 months, whichever comes first. Load and moment ratings are not published for the LRM series; the rating for this specific model is confirmed with us before you order.
This is a complete set: the long carriage ships fitted to the 295 mm rail, pre-greased with Kyodo Yushi PS No. 2, so there is no pairing code to match and no separate rail purchase. Only carriage-only codes (marked BK) omit the rail. Two handling cautions: hold the carriage on inclined rails, since it can slide off under its own weight, and do not force it off at an angle - the ball retainer reduces but does not eliminate the chance of dropped balls. Storage is flat, oiled and bagged, away from heat and humidity.
