Airtac LRM Miniature Linear Guide LRM15L1X110S15BHT
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X110S15BHT 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 LRM15L1X110S15BHT
LRM15L1X110S15BHT is a complete miniature linear guide set with a difference in fixing direction: the trailing T makes this a bottom-mount rail, so the screws go in through the rail's underside and the top face stays clear for the carriage to travel and for your own top-side fixings. Otherwise the set is the 15 mm stainless-steel rail, 110 mm long, with one long recirculating-ball carriage fitted, light preload B and accuracy grade H.
Bottom mounting earns its keep in underslung designs: a stage hung under a plate, or an axis where the rail top must present a clean running surface with no screw heads beside it. Seat the rail on a ground or finish-milled surface, and if you later add a second rail with its own carriages, keep the datum edges on the same side for better running accuracy. The balls are ISO 3290 G10 grade, the seal is a double-lip wiper under a protective outer cover, and ambient temperature must stay at or below 80 C with peaks to 100 C. No load or moment figure is published for LRM, so we confirm the rating for this exact model via the RFQ before you order.

Where the Airtac LRM Miniature Linear Guide LRM15L1X110S15BHT Is Used
Underslung camera axis
A measurement camera riding beneath a granite or aluminium plate: bottom-mount fixing leaves the upper surface free for the optics and the workpiece.
High-cycle parts feeder
A short, fast shuttle indexing small components into a nest, where the light preload of grade B keeps running resistance down over millions of cycles.
Instrument sample tray
A slide-out tray in an analyser that extends for loading and retracts into a sealed measurement position, guided from below so the tray top stays flat.
Is the Airtac LRM Miniature Linear Guide LRM15L1X110S15BHT the Right Guide?
If the duty escalates - heavier mass, a cantilever, shock - switch to LSH, which publishes per-carriage dynamic, static and moment ratings, the one thing LRM's catalogue withholds, so sizing on LRM always ends with us confirming figures for your model. Where travel is short and the priority is crossed-roller stiffness rather than ball smoothness, LGC is the cross-check to run. Checklist for this SKU: set form, 15 mm rail width, long carriage, one carriage, 110 mm rail length, preload B, accuracy H, bottom-mount rail, and a confirmed load rating from us before you cut metal.
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 LRM15L1X110S15BHT FAQ
Rail width 15 mm, rail length 110 mm, one long carriage, preload B (light), accuracy H, and bottom-mount fixing via the trailing T. Torque the fixing screws to 58.8 N.cm (M2) or 196 N.cm (M3) in steel, 39.2 or 127 N.cm in cast iron, 29.4 or 98 N.cm in aluminium. Ambient temperature must not exceed 80 C, with transient peaks to 100 C, and the grease should be renewed every 100 km of travel or every 3 to 6 months, never mixing lubricant types. Load and moment ratings are not published for LRM, so confirm the figure for this model with us before ordering.
When the load is more than light duty or hangs off a bracket. LSH publishes dynamic, static and moment ratings per carriage, and LRM publishes none, so a serious or cantilevered load cannot be sized from this page and instead ends with us confirming figures for the exact model. LRM's strengths are the tight 15 mm envelope, the extended bearing span of the long carriage, and smooth light-duty travel; if the travel is short and stiffness matters more than smoothness, compare LGC's crossed-roller guides as well.
