Airtac LRM Miniature Linear Guide LRM12L1X160S5AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X160S5AH is a miniature linear guide on a 12 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 LRM12L1X160S5AH
This LRM12L1X160S5AH set pairs a 160 mm stainless rail, 12 mm wide, with a single long recirculating-ball carriage; the 5 mm end-hole offset places the first mounting hole close to each rail end, useful when every millimetre of baseplate counts. It ships as one factory-assembled set in plain finish - rail and carriage together, greased with Kyodo Yushi PS No. 2.
Specifying the long carriage costs nothing in availability here: long blocks are stocked as deeply as standard ones (512 against 475 sets), so the extended bearing span of the L body is readily on hand. Price across our LRM stock runs about $66 to $831, and with only two rail widths on sale that spread is almost entirely rail length and carriage count - trimming travel saves money faster than changing size. Ambient temperature limit is 80 C with 100 C transient peaks. No load or moment ratings are published for LRM; we confirm them per model via the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X160S5AH Is Used
Laser diode collimator slide
Setting a collimating lens against a laser diode takes fine, repeatable axial slides; the grade H rail and long carriage keep the lens axis steady while you tune for beam quality.
Vision camera track on a sorter
A machine-vision camera riding a 160 mm track above a fast parts feeder needs smooth starts; the recirculating-ball design keeps the image steady frame after frame.
Vial indexing on a micro filler
On a laboratory micro-filler, a short rail indexes vial carriers into filling position; the long block resists the tipping of a tall, light vial under quick stops.
Is the Airtac LRM Miniature Linear Guide LRM12L1X160S5AH the Right Guide?
Take a moment before fixing the size: on a 12 mm rail the job is clearly light-duty, and if it ever grows a cantilever or a heavier payload, LSH is the series with published dynamic, static and moment ratings to size against - LRM offers no load table at all. If travel is short and rigidity per millimetre matters more than load, crossed-roller LGC is the alternative to compare.
For this exact set, confirm: complete-set form (rail plus one long carriage), 12 mm rail width, 160 mm rail length, preload A (smoothest running, least rigid), accuracy H, top-mount, 5 mm end offset, and a load rating checked with us before you order.
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 LRM12L1X160S5AH FAQ
Confirmed data: 12 mm stainless rail, 160 mm long, one long carriage, preload A, accuracy H, top-mount with a 5 mm end-hole offset. Fixing screws torque to 196 N.cm into steel or 98 N.cm into aluminium for M3 (M2: 58.8 N.cm into steel). The ambient limit is 80 C, peaks 100 C, and re-greasing is due every 100 km of travel or every 3 to 6 months. Dynamic load, static load and moment ratings are deliberately absent from the LRM catalogue - we confirm the rating for this model individually, so include it in your RFQ.
It is the complete set: one 12 mm by 160 mm stainless rail with one long carriage factory-fitted and pre-greased. If you ever need a spare block on its own, carriage-only LRM12 codes exist, but our carriage-only stock is very thin, so plan on a special order or keep a whole spare set.
