Airtac LRM Miniature Linear Guide LRM15L1X160S20AH
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X160S20AH 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 LRM15L1X160S20AH
This AirTAC part number is a complete LRM set: a 15 mm stainless-steel rail trimmed to 160 mm and one long-body recirculating-ball carriage, ordered with preload A (no preload) and accuracy grade H. The end holes sit 20 mm in from each rail end for top-mount screws. Nothing else is required to build the axis - rail, carriage, seals and covers ship fitted together.
Two details are easy to overlook here. First, the carriage ships pre-filled with Kyodo Yushi PS No. 2 grease, and the 100 km re-grease interval arrives faster than it sounds on a short-stroke axis: a 200 mm stroke cycling once per second covers 100 km in roughly three weeks of continuous running, so plan servicing around distance, not just the calendar. Second, the recirculating balls are Japanese ISO 3290 G10 grade, held by the ball-retention design, yet inserting the carriage at an angle can still drop balls, so work square and slowly - a dummy rail helps. Ambient temperature must stay within 80 C, peaking at most 100 C. Load and moment figures are confirmed per model; ask us through the RFQ before you finalise the design.

Where the Airtac LRM Miniature Linear Guide LRM15L1X160S20AH Is Used
Machine-vision camera slide
Mounting an inspection camera on a linear slide to reframe over a compact field of view suits this 160 mm rail; top-mount holes at a 20 mm end offset make the drilling pattern straightforward to plan.
Laser-diode alignment fixture
Aligning a small laser module against a photodetector calls for fine, smooth adjustment without stick-slip; the G10-grade balls and double-lip seal keep motion clean at bench temperatures well under the 80 C limit.
Label-applicator dispensing slide
A compact applicator sweeping labels onto cartons at desktop scale uses the single long carriage to carry the peel edge; carriage swaps are rare, but when one is needed a dummy rail helps seat the replacement.
Is the Airtac LRM Miniature Linear Guide LRM15L1X160S20AH the Right Guide?
Size this series honestly. If the load is substantial or cantilevered, move up to AirTAC LSH, which publishes per-carriage dynamic, static and moment ratings you can calculate against - LRM carries no published figures at all. If the travel is short and the priority is crossed-roller rigidity, LGC is the better cross-series choice. When specifying LRM15L1X160S20AH, confirm: complete-set form, 15 mm rail width, long carriage, one carriage on a 160 mm rail, preload A, accuracy H, top-mount fixing, and the 20 mm end-hole offset against your hole pattern. Finally, confirm the load rating with us before committing. Price note: across our stocked range the spread runs roughly $66 to $831, and rail length, not width, is what drives it.
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 LRM15L1X160S20AH FAQ
Rail width 15 mm, rail length 160 mm, one long carriage, preload A (none), accuracy H, top-mount fixing with a 20 mm end-hole offset. Screw tightening: M2 - 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 - 196, 127 and 98 N.cm. Ambient temperature must stay at or below 80 C, with peaks to 100 C, and re-greasing falls due every 100 km of travel or every 3 to 6 months. Basic dynamic, static and moment ratings are not published for LRM; we confirm them per model, so send the RFQ.
Choose LRM when the envelope is small and the duty light - this set is a 15 mm rail just 160 mm long with a single carriage. Choose LSH when the load is substantial or cantilevered, because LSH publishes per-carriage dynamic, static and moment ratings you can size against; LRM publishes none, and we confirm the figures per model instead. If travel is short and you need crossed-roller rigidity, compare LGC. Whatever you pick, confirm the load with us before ordering rather than estimating.
