Airtac LRM Miniature Linear Guide LRM15L1X160S20AHT
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X160S20AHT 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 LRM15L1X160S20AHT
LRM15L1X160S20AHT is the bottom-mount version of this 15 mm miniature guide: a stainless-steel rail 160 mm long, its fixing holes positioned for screws driven from below, carrying a single long recirculating-ball carriage at preload A (none) and accuracy grade H. The complete set arrives assembled - rail, carriage, double-lip seal and outer cover.
Bottom-mounting matters where the top face of the machine deck must stay clear or flush, since the screws hide under the rail instead of running along it. Prepare the seating surface by grinding or finish-milling so the travel accuracy is actually achieved, and pick either rail edge as the datum; with more than one carriage, keep the datum on the same side for better running accuracy. Inside the carriage, Japanese ISO 3290 G10 balls run under the double-lip seal. Hold the carriage when working on an inclined rail, as it can slide off under its own weight, and keep ambient temperature at or under 80 C (100 C transient peaks). Load and moment ratings are published nowhere for LRM; we confirm them for this exact model via the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM15L1X160S20AHT Is Used
Slim measurement jig base
A flat measurement jig with no space above the deck for screw heads takes the rail from below, leaving the top surface uninterrupted for the workpiece and the probe.
Enclosed cuvette-handler axis
Inside a sealed analytical instrument housing, screws cannot be reached from above after assembly; bottom-mounting the 160 mm rail lets the builder close the cover and never revisit the fixing.
Optics-bench filter slider
A small optics bench moving filters or mirrors between positions gains from the smooth low-friction travel of a preload-A long carriage, and the underside fixing keeps the optical plane clear.
Is the Airtac LRM Miniature Linear Guide LRM15L1X160S20AHT the Right Guide?
Choose LRM for miniature, smooth, light-duty positioning; choose LSH when loads grow or hang off a cantilever, because LSH publishes per-carriage dynamic, static and moment ratings to size against while LRM does not; choose LGC for short travel where crossed-roller rigidity wins. Before ordering LRM15L1X160S20AHT, run the checklist: complete set (rail plus one carriage), 15 mm rail, long carriage, 160 mm rail length, preload A (none), accuracy H, bottom-mount rail with a 20 mm end offset - then confirm the load rating with us, per model, before committing. The mounting surface must be ground or finish-milled for the accuracy grade to mean anything in service.
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 LRM15L1X160S20AHT FAQ
A 15 mm stainless rail 160 mm long, one long recirculating-ball carriage, preload A (none), accuracy grade H and bottom-mount rail fixing with a 20 mm end-hole offset. Tighten M2 screws to 58.8 N.cm in steel (39.2 cast iron, 29.4 aluminium) and M3 to 196 N.cm (127, 98). Ambient temperature limit is 80 C with 100 C transient peaks; re-grease every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for this series - confirmed per model through us.
This SKU is a complete set: the 160 mm stainless-steel rail with one fitted long carriage - not a bare carriage and not a rail alone. Spare carriages are ordered with a BK code that ends in a pairing letter which must match the rail; read it off the original part before ordering. Our carriage-only stock is limited to a handful of SKUs, so most replacement carriages are special orders, and fitting one is safest done square and slowly - ideally on a dummy rail - because even the ball-retention design can drop balls on a hasty swap.
