Airtac LRM Miniature Linear Guide LRM12L1X295S10CPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X295S10CPT 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 LRM12L1X295S10CPT
LRM12L1X295S10CPT is a complete AirTAC LRM set: 295 mm of 12 mm wide stainless-steel rail carrying one long recirculating-ball carriage, ordered in the precision P accuracy grade, medium preload C, with the rail drilled for bottom mounting so fasteners are fitted from below. The carriage stays on the rail in transit thanks to the ball-retention design, and the set ships pre-greased.
The combination of precision grade and bottom mounting suits machines where the guide lives inside a housing with an unbroken outer surface - the running accuracy of P without visible screw heads on the top face. Handle the assembly with care: ball retention is a handling aid, not a guarantee, and the manufacturer warns that inserting the carriage at an angle or fitting and removing it quickly can still drop balls. Keep ambient temperature at or below 80 C, with peaks no higher than 100 C, and re-grease every 100 km of travel or every 3 to 6 months - at a 200 mm stroke cycling once a second, that distance arrives in about three weeks of continuous duty. LRM has no published load or moment ratings; send the RFQ and we will confirm the rating for this specific configuration before you order.

Where the Airtac LRM Miniature Linear Guide LRM12L1X295S10CPT Is Used
Probe stage inside a metrology fixture
Precision-grade travel and a concealed bottom-mounted rail keep the working surface of an inspection fixture smooth and easy to wipe down.
Semiconductor test-head positioning slide
The long carriage supports an overhanging connector block, while preload C holds position against the reversal shocks of a test cycle.
Fastener-feed shuttle in a small assembly cell
Light screw-and-nut payloads suit a 12 mm miniature rail, and the stainless rail surface tolerates the oily environment around feed tracks.
Is the Airtac LRM Miniature Linear Guide LRM12L1X295S10CPT the Right Guide?
Bottom mounting changes how you service the guide, not how you choose it. The long carriage spreads the load over more balls and extends the bearing span, which is welcome where tooling overhangs the block; precision P is worth specifying when the guide positions something that is measured, imaged or bonded. If the load is substantial or cantilevered, however, move up to LSH - it publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not. For short travel with a crossed-roller rigidity requirement, compare LGC.
Checklist before ordering: form (complete set), 12 mm rail width, long carriage, one block, 295 mm rail length, preload C - rigid but less forgiving of imperfect mounting surfaces, so grind or finish-mill the seats - accuracy P, bottom-mount direction, and a confirmed load rating from us. Note that either side of the rail can serve as the datum face; with two or more carriages, keep the datum on the same side for each.
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 LRM12L1X295S10CPT FAQ
Complete set with a 12 mm wide, 295 mm long stainless-steel rail, one long carriage, preload C (medium), accuracy P (precision), bottom-mount rail. M3 screw torque is 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium; M2 screws take 58.8, 39.2 and 29.4 N.cm. Ambient limit is 80 C with transient peaks to 100 C; re-grease every 100 km of travel or every 3 to 6 months. Load, moment and running-parallelism ratings are not published for LRM - we confirm them per model via the RFQ.
Decide on the load question. If you can size the application from published dynamic, static and moment ratings - which LSH publishes per carriage and LRM does not - and the duty is heavy or overhung, LSH is the engineering-safe answer. If the envelope is tight, the payload light and smooth precision travel is the goal, this 12 mm, 295 mm LRM set fits. Short travel needing crossed-roller rigidity points to LGC instead. Send load, orientation and stroke in the RFQ and we will confirm which series and which ratings apply.
