Airtac LRM Miniature Linear Guide LRM15L1X270S15BP
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X270S15BP 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 LRM15L1X270S15BP
The LRM15L1X270S15BP arrives as a complete miniature guide: a 270 mm long, 15 mm wide stainless-steel rail with a single long-body (L) recirculating-ball carriage on it, a 15 mm end-hole offset (S15), light preload B and - the difference from its H-grade sibling - precision accuracy grade P, on a plain top-mount rail that bolts down through its top face.
Precision grade is the tighter of the two accuracy grades offered on LRM, which helps when paired rails must run true together in a twin-rail layout. The long carriage carries its Japanese ISO 3290 G10 balls (the grade covers the balls only) over a longer footprint, and the double-lip seal plus outer cover keep grease in and debris out. Keep the ambient temperature at or under 80 C, with peaks no higher than 100 C. Load and moment ratings are not published for this series; describe the duty in your RFQ and we confirm the figures for this exact model before you order. One cost note worth knowing: rail length drives the price of stocked LRM sets far more than rail size does, so trimming unnecessary travel is the cheapest saving available.

Where the Airtac LRM Miniature Linear Guide LRM15L1X270S15BP Is Used
Vision measuring stage
A compact XY visual-inspection stage benefits from precision grade P, where two matched rails must carry the camera bridge without yaw drift between them.
Laboratory autosampler X-bridge
In a lab autosampler the long carriage supports the sampling arm across the 270 mm span, while light preload keeps drag low for fast, repeatable probe moves.
Laser beam-path alignment slider
A fine-adjust slider for optical alignment uses the tighter precision grade to hold repeatable positioning, and the outer cover shields the seal strip from airborne dust near the source.
Is the Airtac LRM Miniature Linear Guide LRM15L1X270S15BP the Right Guide?
Three questions decide it. First, load: if the duty is substantial or overhung, AirTAC LSH publishes dynamic, static and moment ratings per carriage that you can size against, which LRM does not - so step up rather than guess. Second, travel and rigidity: for short strokes needing crossed-roller stiffness, LGC fits better. Third, this exact configuration: complete set with rail included, 15 mm rail width, long carriage, one carriage, 270 mm rail, light preload B (quickest to install, but it leaves the most clearance under load reversal), precision grade P, top-mount rail - and confirm the load rating with us before committing. Also note that long carriages are stocked as deeply as standard ones, so specifying the L body here costs nothing in availability.
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 LRM15L1X270S15BP FAQ
Complete set: 15 mm rail width, 270 mm rail length, one long carriage, preload B (light), accuracy P (precision), top-mount rail, 15 mm end-hole offset. Screw torques: M2 at 58.8 N.cm into steel, 39.2 N.cm into cast iron, 29.4 N.cm into aluminium; M3 at 196, 127 and 98 N.cm respectively. Re-grease every 100 km of travel or every 3 to 6 months and keep ambients at or below 80 C, peaks to 100 C. Load and moment ratings are not published for LRM - we confirm them per model through the RFQ.
Pick LRM when a tight envelope, smooth running and a 15 mm miniature section matter more than published ratings. Pick LSH when the load is heavy or overhung, because LSH publishes dynamic, static and moment ratings per carriage that you can verify in a calculation, while LRM ratings are confirmed per model only. If the stroke is short and you need crossed-roller rigidity instead, LGC is the third option worth comparing.
