Airtac LRM Miniature Linear Guide LRM15L1X190S15CPT
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X190S15CPT is a miniature linear guide on a 15 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 LRM15L1X190S15CPT
The LRM15L1X190S15CPT is a complete miniature linear guide set: a 190 mm stainless-steel rail 15 mm wide, carrying one long recirculating-ball carriage that bolts down from underneath, since the trailing T in the code specifies bottom-mount fixing. The carriage length code L gives a longer body than the standard block, spreading contact across more recirculating balls and stretching the span that resists tipping. Preload is grade C (medium) and accuracy grade P (precision). Rail and carriage ship together, greased and ready to fix down.
Medium preload is the rigid choice - it takes out play firmly but forgives less installation error, so grind or finish-mill the mounting face and keep the datum side consistent. Inside the carriage, Japanese-made balls graded ISO 3290 G10 recirculate in the LRM common-rail profile, behind a double-lip seal and an outer cover that hides the screws and shields the seal strip. Ambient temperature must stay at or below 80 C, with 100 C peaks tolerated only briefly. No load or moment figure is published for LRM; send the RFQ and we will confirm the ratings for this exact set before you order.

Where the Airtac LRM Miniature Linear Guide LRM15L1X190S15CPT Is Used
Optical inspection fixture
Bottom fixing leaves the rail's top face completely clear, so a camera or vision sensor can travel over PCB samples without brackets crossing the optics.
Semiconductor test handler
A long carriage under medium preload carries a light test head across a socket array, resisting the tipping that a shorter block would allow over the 190 mm span.
Laser alignment slide
Precision-grade travel trims a fold-mirror position in a compact lab laser, with underside mounting keeping every fastener out of the beam path.
Is the Airtac LRM Miniature Linear Guide LRM15L1X190S15CPT the Right Guide?
If the load is substantial or cantilevered, step up to the LSH series, which publishes per-carriage dynamic, static and moment ratings you can size against - numbers LRM never prints. For short travel where crossed-roller rigidity matters more than stroke, LGC is the better fit. Before committing, run the checklist: complete-set form, 15 mm rail width, long carriage, single block, 190 mm rail, medium preload C (stiff, but less tolerant of mounting error), precision accuracy P, bottom-mount direction, and a confirmed load rating from us for this model. Also budget for grease: the 100 km interval is nearer than it sounds, since a 190 mm stroke cycling once per second covers it in about three weeks of continuous running.
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 LRM15L1X190S15CPT FAQ
Rail width 15 mm, rail length 190 mm, one long carriage, medium preload C, precision accuracy P, bottom-mount rail. Screw torques: M2 at 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 at 196, 127 and 98 N.cm. The ambient limit is 80 C with 100 C peaks. Carriages ship filled with Kyodo Yushi PS No. 2 grease and need renewing every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them per model through the RFQ.
Go to LSH when the load is heavy or overhung: it publishes dynamic, static and moment ratings per carriage, so capacity can be checked on paper, whereas LRM publishes none and we confirm figures model by model instead. Stay with this LRM set when the 15 mm rail width, low profile and 190 mm long-carriage travel fit the envelope better. For genuinely short strokes needing crossed-roller stiffness, LGC is the third option.
