Airtac LRM Miniature Linear Guide LRM15L1X270S15BHT
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X270S15BHT 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 LRM15L1X270S15BHT
The trailing T in LRM15L1X270S15BHT changes where the fasteners live: this 15 mm rail fixes through the underside, a design where you cannot reach screw heads from above because the top face is the working surface. The set itself is a 270 mm stainless-steel rail with one long recirculating-ball carriage, built for light-duty precision positioning in a compact envelope.
Preload grade B adds a light internal pre-stress on the balls, removing clearance for a firmer feel than the unloaded A grade while staying easier to mount than medium C. The balls are Japanese ISO 3290 G10 grade - that grade describes the balls only, not the guide assembly. A double-lip seal plus outer cover protect the raceway, the common-rail profile lets other LRM15 carriages share this rail, and the ambient limit is 80 C with 100 C transient peaks. One timing note: the 100 km re-grease interval arrives faster than it sounds, because a 200 mm stroke cycling once per second covers that distance in roughly three weeks of continuous running. Load and moment figures are confirmed per model - send us the RFQ and we quote the rating for this exact code.

Where the Airtac LRM Miniature Linear Guide LRM15L1X270S15BHT Is Used
Desktop gantry cross-slide
Serving as the cross-slide rail of a small desktop gantry, where underside fixing keeps the top of the rail completely clear for the moving plate.
Laser marker head track
Carrying a low-power laser marker head along a 270 mm path inside a compact marking unit, with light preload damping any play at the head.
Microscope lens turret slide
Sliding a lens carrier in an automated microscope station, where the long body spreads the overhanging optics load across more recirculating balls.
Is the Airtac LRM Miniature Linear Guide LRM15L1X270S15BHT the Right Guide?
Because LRM publishes no load or moment ratings, size the machine against LSH when the load is heavy or hangs on a cantilever - LSH lists dynamic, static and moment ratings per carriage that you can plug straight into a calculation. When travel is short and crossed-roller rigidity is the goal, look at LGC instead. For this code, check: complete-set form, 15 mm rail width, long carriage, one block on a 270 mm rail, light preload B (a stiffer feel, but the mounting surfaces must be ground or finish-milled to hold travel accuracy), accuracy H, bottom-mount direction, and a confirmed load rating from us before you commit.
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 LRM15L1X270S15BHT FAQ
Rail width 15 mm, rail length 270 mm, one long carriage, preload grade B (light), accuracy grade H (high), and bottom-mount fixing through the rail underside. Assembly torque runs from 58.8 N.cm for M2 screws in steel up to 196 N.cm for M3 screws in steel, and the ambient limit is 80 C with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months. Dynamic, static and moment ratings are not published for LRM; we confirm them for this model on request.
Choose LRM15 when the envelope is tight and the duty is light - the value here is precision, smoothness and a slim 15 mm profile. Choose LSH when the load is substantial or cantilevered, because LSH publishes per-carriage dynamic, static and moment ratings you can size against, while LRM ratings are confirmed per model through us. Whichever you pick, grind or finish-mill the mating surfaces: the rated travel accuracy depends directly on the surface quality under the rail.
