Airtac LRM Miniature Linear Guide LRM15L1X190S15BPT
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X190S15BPT 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 LRM15L1X190S15BPT
This is a complete LRM15 miniature linear guide set: one stainless-steel rail, 15 mm wide and 190 mm long, carrying a single long recirculating-ball carriage. The code also fixes a 15 mm end-hole offset, light preload (B), precision accuracy grade (P) and a bottom-mount rail, so the rail is drilled for fastening from below through its base. Fixing screws and lubricant are not part of the delivery.
Because the carriage is the long L version, the balls run over a longer effective footprint, which steadies any tipping tendency at the cost of a slightly longer installed length. The balls inside are ISO 3290 G10 grade Japanese balls - the grade applies to the balls themselves - running behind a double-lip seal that scrapes oil back and excludes dust, while an outer cover shields the seal strip and screw line. Ambient temperature must stay at or below 80 C, with brief peaks to 100 C - worth remembering near warm optics or a curing lamp. LRM has no published load or moment ratings, so we confirm the figures for this exact model when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM15L1X190S15BPT Is Used
Die inspection microscope stage
A compact semiconductor inspection microscope moving over a 190 mm scan line benefits from the smooth, lightly preloaded travel and precision P grade on a 15 mm stainless rail.
Optical fiber alignment slide
Aligning a fiber to a laser diode calls for fine, steady translation; the long carriage resists pitch and the P accuracy grade keeps the path true across the 190 mm rail.
Laser power meter carriage
Sweeping a small power meter head across a beam path on a miniature stage suits light preload B, which glides with minimal stiction for delicate positioning.
Is the Airtac LRM Miniature Linear Guide LRM15L1X190S15BPT the Right Guide?
If the load is substantial or hangs off a cantilever, step up to AirTAC LSH: that series publishes per-carriage dynamic, static and moment ratings you can actually size against, which LRM does not. For short travels needing crossed-roller rigidity, LGC is the closer match. Before ordering, check the form (this is a complete set), 15 mm rail width, long carriage, one carriage, 190 mm rail, light preload B - the smoothest-running grade on offer here, with slightly more float under load - precision P accuracy, bottom-mount direction, and confirm the load rating with us first.
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 LRM15L1X190S15BPT FAQ
Rail width 15 mm, rail length 190 mm, one long carriage, light preload B, precision P accuracy, bottom-mount rail fixing with a 15 mm end-hole offset. Assembly torque: M2 screws 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 screws 196 N.cm into steel, 127 into cast iron, 98 into aluminium. Ambient limit is 80 C with transient peaks to 100 C, and 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 before ordering.
Choose LRM when the envelope is tight and the duty is light; LRM15 gives you a 15 mm stainless rail in a small footprint with precision P travel. Choose LSH when the load is heavier or overhung, because LSH publishes dynamic, static and moment ratings per carriage that you can size against, while LRM's ratings are confirmed per model through us. Send the RFQ with your load and moment conditions and we will tell you honestly which series fits.
