Airtac LRM Miniature Linear Guide LRM15L1X190S15BHT
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X190S15BHT 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 LRM15L1X190S15BHT
This is the bottom-mount (T) version of the 15 mm LRM set: a 190 mm long, 15 mm wide stainless-steel rail, end holes 15 mm from each rail end, carrying one long (L) carriage. Bottom-mount fixing suits frames where the top of the rail has to stay clear or the screws cannot be reached from above - the fasteners are installed from the underside.
Fit it to a mounting face that has been ground or finish-milled; the catalogue's surface-preparation table, listed as five rows per size, gives the Q1, Q2, H1 and R limits to work to. Inside the carriage, Japanese ISO 3290 G10 balls - the grade covers the balls only - run in a retention design that stops them falling out during handling, behind a double-lip seal and an outer cover. Light preload (grade B) trims the free play without much running drag. Ambient temperature must not exceed 80 C, with brief peaks to 100 C, and if the machine sits the rail on an incline, remember the carriage can slide under its own weight during fitting. Load and moment ratings are not published; request them through the RFQ and we confirm them for this model.

Where the Airtac LRM Miniature Linear Guide LRM15L1X190S15BHT Is Used
Pouch heat-seal station guide
A light sealing or crimping head near warm tooling suits this format - just keep the ambient at or below 80 C, the one published environmental limit, with peaks no higher than 100 C.
Retrofit slide in a slim machine frame
Maintenance teams adding a light traverse to an existing frame bolt this bottom-mount rail in from below, leaving the running surface flush with the frame.
Vial-tracking slide on a lab conveyor
A small gate or sensor carrier indexing vials on a laboratory conveyor line rides the single long carriage over the 190 mm rail.
Is the Airtac LRM Miniature Linear Guide LRM15L1X190S15BHT the Right Guide?
Match the form to the frame first: this is a complete set, rail and fitted carriage, with bottom-mount fixing for frames serviced from below. Then check the numbers we can state - 15 mm rail width, 190 mm rail length, long carriage, single block, preload B (light), accuracy H (high). The trade-off with light preload is a slightly firmer running feel in exchange for less play. When the load is substantial or cantilevered, do not size this guide by guesswork: LRM publishes no dynamic, static or moment ratings, whereas AirTAC LSH publishes per-carriage values you can design against - move up to LSH there, or across to LGC where travel is short and crossed-roller rigidity is the priority. Confirm the load rating with us per model through the 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 LRM15L1X190S15BHT FAQ
Design to: 15 mm rail width, 190 mm rail length, 15 mm end-hole offset, one long carriage, light preload (grade B), high accuracy (grade H), bottom-mount fixing. Use 58.8 N.cm for M2 screws in steel (39.2 cast iron, 29.4 aluminium) and 196 N.cm for M3 (127 cast iron, 98 aluminium). Keep the ambient 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. Dynamic, static and moment ratings are not published for this series; we confirm them for the exact model via your RFQ.
Pick LRM when the space is tight and the duty is light-precision; that is what this 15 mm, 190 mm bottom-mount set is for. Pick AirTAC LSH when the load is heavy or overhangs the carriage, because LSH publishes per-carriage dynamic, static and moment ratings that LRM simply does not have. Pick LGC when the travel is short and you want crossed-roller stiffness. Either way, send us the load case and we confirm the rating for the exact model before you commit.
