Airtac LRM Miniature Linear Guide LRM12L2X445S10BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X445S10BP is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriages. 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 LRM12L2X445S10BP
This LRM12L2X445S10BP is a precision-grade complete set: a 12 mm stainless-steel rail, 445 mm long, carrying two long carriages under light preload (B). Accuracy code P is the tighter of the two grades LRM offers, and it shows up as more consistent running over the full stroke - the reason to pick it over the H version of the same geometry. Top-mount fixing, 10 mm end-hole offset.
Under the outer cover, which hides the fixing screws and shields the seal strip, each carriage runs recirculating balls in Japanese-made ISO 3290 G10 grade - balls only; the guide as a whole is not built to any stated standard - wiped and greased by a double-lip seal. The common-rail design means long and standard carriages share one LRM12 rail profile, so a future carriage of either length fits the same rail. Ambient limit is 80 C continuous, 100 C transient peak. Where a capacity figure would normally sit in a datasheet there is none: LRM load and moment ratings are confirmed per model, so send the RFQ and we will return the numbers for this set.

Where the Airtac LRM Miniature Linear Guide LRM12L2X445S10BP Is Used
Wire-bond alignment stage
A wire-bonder or die-attach station where P-grade accuracy keeps positional scatter down across the full 445 mm of travel on light payloads.
Granite metrology slide
A measuring slide on a small granite surface plate, where the precision grade and smooth ball recirculation support repeatable probe positioning on inspection loads.
Optical sensor calibration bench
Calibrating small optical sensors calls for repeatable, high-grade travel; the two-carriage layout damps pitch so the sensor stays square to the source.
Is the Airtac LRM Miniature Linear Guide LRM12L2X445S10BP the Right Guide?
Sizing starts with accuracy: if the job needs the tighter running consistency of P grade, this set carries it; if H would do, the same geometry is stocked at high accuracy too. Then confirm form (complete set), rail width 12 mm, long carriages, count 2, rail length 445 mm, preload B, and top-mount direction. Preload B trades a little running drag for the removal of play - a good trade on well-ground surfaces; on rougher ones consider preload A. When loads grow or hang off a cantilever, move up to LSH, whose published dynamic, static and moment ratings let you calculate margins - something the LRM catalogue does not offer; for short strokes needing crossed-roller stiffness, cross to LGC. Confirm the load rating with us by RFQ before you commit.
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 LRM12L2X445S10BP FAQ
Rail width 12 mm, rail length 445 mm, two long carriages, light preload (code B), precision accuracy (code P), top-mount rail fixing, 10 mm end-hole offset. Mounting screws: 58.8 N.cm for M2 into steel (39.2 cast iron, 29.4 aluminium) and 196 N.cm for M3 into steel (127 cast iron, 98 aluminium). Ambient temperature limit is 80 C with transient peaks to 100 C; re-grease every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm the figures for this exact set before ordering.
A complete set, not loose parts: the 445 mm stainless-steel rail plus two long carriages shipped mounted on it, with preload B and P accuracy already built in. There is no pairing code to worry about because rail and carriages come together as one matched assembly. If you later want a standalone spare carriage, note that carriage-only LRM stock is very thin - four SKUs in total - so plan ahead or keep a second complete set.
