Airtac LRM Miniature Linear Guide LRM12N1X170S10BH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X170S10BH 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 LRM12N1X170S10BH
LRM12N1X170S10BH is the light-preload build of the 12 mm miniature set: a stainless-steel rail 170 mm long with a 10 mm end-hole offset, one standard-length carriage and top-mount fixing holes, all to accuracy grade H. Preload code B places a slight interference between the balls and raceways, taking up the internal clearance that a zero-preload carriage leaves behind.
That slight interference is the point of this SKU. If your mechanism reverses direction quickly or must not rock under a small overturning component, light preload removes the rattle without adding much drag. Installation demands more care than the free-running version: the mounting surface should be ground or finish-milled to hold travel accuracy, and the catalogue's surface-preparation rows (Q1 from 2 to 5 mm, Q2 from 1.2 to 3.2 mm, H1 from 1.5 to 3.5 mm, edge R from 0.2 to 0.5 mm, listed per size) tell you what to machine to. The running balls are ISO 3290 G10 Japanese grade, a double-lip seal and outer cover guard the raceways, and the ambient limit is 80 C with 100 C peaks. AirTAC publishes no load or moment rating for LRM; we verify it for this model via the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X170S10BH Is Used
Diode-laser focusing stage
A laser-diode focusing holder adjusted by hand benefits from light preload: the carriage stays where the technician sets it without rocking, yet still glides along its 170 mm rail.
Small-parts feeder pusher
A pusher sorting pins or springs into bins reverses direction thousands of times per shift; preload B takes up the clearance so the pusher does not knock at each reversal.
Vial labeling head guide
A labeling head traversing pharmaceutical vials on a packaging line needs quick, repeatable strokes; the light preload holds position between label cycles without loading the drive.
Is the Airtac LRM Miniature Linear Guide LRM12N1X170S10BH the Right Guide?
Size the purchase by travel and carriage count first: within the LRM line the price runs from about $66 to $831, and almost all of that spread comes from rail length and block count rather than the 12 mm width. If the application pushes beyond light duty - real cantilevers, impacts, heavy payloads - choose LSH instead, because it is the series with published dynamic, static and moment ratings you can design to. For very short travel where crossed-roller rigidity matters, look at LGC. This exact checklist applies: complete set, 12 mm rail, standard carriage, one block, 170 mm length, preload B, accuracy H, top-mount. Send us the load and duty cycle and we will confirm the ratings for the model 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 LRM12N1X170S10BH FAQ
Rail: 12 mm wide, 170 mm long, 10 mm end-hole offset, top-mount. Carriage: one, standard length, light preload (B), accuracy grade H. Installation: grind or finish-mill the mounting face, torque M3 screws to 196 N.cm in steel, 127 N.cm in cast iron or 98 N.cm in aluminium. Environment: 80 C maximum ambient, 100 C transient peaks. Maintenance: first charge and top-up grease quantities are given per model (the range runs from 0.02/0.01 to 1.0/0.50 cm3), with re-greasing every 100 km or 3 to 6 months. Load and moment ratings are not published for LRM and are confirmed per model with us.
One rail and one carriage, assembled as a set and pre-filled with Kyodo Yushi PS No. 2 grease. No screws, bolt caps or second carriage are included - you supply the mounting screws to suit your plate. The carriage is already fitted to the rail, so there is no pairing code to match here; pairing codes only apply to carriage-only codes. Carriage-only replacements are scarce in our range, so if you plan field swaps, order spare blocks at the same time as the set.
