Airtac LRM Miniature Linear Guide LRM15L1X190S15APT
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X190S15APT 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 LRM15L1X190S15APT
LRM15L1X190S15APT is a complete miniature linear guide set from AirTAC: one 190 mm stainless-steel rail, 15 mm wide, with fixing holes offset 15 mm from each end, supplied with a single long (L) recirculating-ball carriage already fitted. The trailing T in the code sets the bottom-mount format, so the rail is secured from beneath and the running surface stays flush - useful where nothing may stand proud of the rail.
Because the carriage is long, the ball complement is spread over a greater footprint, which steadies any tipping tendency at the tool. The design includes a common rail profile shared by LRM carriages, ball retention that holds the balls during handling, Japanese-made ISO 3290 G10 balls for roundness (a grade for the balls alone), a double-lip seal for grease retention and dust exclusion, and an outer cover over the fixings. Ambient temperature must stay at or below 80 C, with transient peaks no higher than 100 C. Preload grade A gives the lightest running feel, and the finished travel accuracy depends on a ground or finish-milled mounting surface. A load rating is not published for LRM - we confirm the figures for this exact model when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM15L1X190S15APT Is Used
Wafer inspection micro-stage
A 15 mm wide rail under a compact optics head keeps a small wafer-inspection camera on a repeatable line over short samples, in exactly the tight envelope miniature guides are made for.
Laboratory optics alignment fixture
Labs shifting lens holders and detectors between setups use the zero-preload, precision-grade travel for repeatable positioning of light components on the bench.
Machine-vision camera slide
A vision camera traversing above an electronics line benefits from the flush bottom-mounted rail, so nothing on top of the guide obstructs the field of view.
Is the Airtac LRM Miniature Linear Guide LRM15L1X190S15APT the Right Guide?
Size up honestly. If the load is substantial or cantilevered, move to the AirTAC LSH series, which publishes per-carriage dynamic, static and moment ratings you can calculate against - LRM does not, so any sizing here has to be confirmed with us per model. If the travel is short and the job needs crossed-roller rigidity, LGC is the closer match. For this set, check: it is a complete rail-plus-carriage set (not a spare carriage), the rail width is 15 mm, the carriage is long with a single block, the rail is 190 mm, preload is A (none), accuracy is P (precision), and the mounting direction is bottom-mount. Confirm the load rating with us before you commit, and note that size 15 is stocked in smaller volume than size 12 - availability is good but worth checking for repeat orders.
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 LRM15L1X190S15APT FAQ
It is a complete set: 15 mm rail width, 190 mm rail length with a 15 mm end-hole offset, one long (L) carriage, preload grade A (none), accuracy grade P (precision), bottom-mount rail fixing. Screw torques are 58.8 N.cm for M2 into steel (39.2 cast iron, 29.4 aluminium) and 196 N.cm for M3 (127 cast iron, 98 aluminium). Ambient temperature must stay at or below 80 C with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM; we confirm them for this model when you send the RFQ.
LRM wins when the envelope is tight and the duty is light: a 15 mm rail, long carriage and precision-grade travel in a small footprint. But LRM publishes no dynamic, static or moment ratings, so if the load is substantial or cantilevered, AirTAC LSH is the safer choice - its catalogue lists per-carriage ratings you can size against, which LRM cannot. For short travel needing crossed-roller rigidity, LGC is the better match. Tell us the load and we will confirm whether this LRM set is right before you order.
