Airtac LRM Miniature Linear Guide LRM12N1X370S10BPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X370S10BPT 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 LRM12N1X370S10BPT
A precision-grade slide for a base you fasten from underneath: the LRM12N1X370S10BPT pairs accuracy grade P with a bottom-mount rail. The set is one 12 mm wide stainless rail, 370 mm long with a 10 mm end-hole offset, carrying a single standard-length recirculating-ball carriage, assembled and pre-lubricated before it ships. At 370 mm it sits comfortably inside the 1005 mm full-length size 12 rail, so it is cut from one piece - no spliced joint, no matching of engraved serial pairs, and none of the joint alignment work a two-section rail demands.
Bottom-mount fixing earns its place when the top of the machine bed is finished, slotted or simply unreachable: the screws are set from below the rail, so the layout suits a base drilled from the back or the underside, such as a plate sitting in a channel where you cannot get a driver over the top. Accuracy P is the tighter of the two grades offered on LRM, worth specifying when a second axis stacks above this one. Inside, the balls are grade G10 to ISO 3290 and Japanese-made; the double-lip seal works lubricant back along the track while the outer cover keeps debris off the seal strip. Keep the environment at or below 80 C, with brief peaks to 100 C. Load and moment ratings are not published for this series; tell us the duty via RFQ and we will confirm the figures for this exact configuration.

Where the Airtac LRM Miniature Linear Guide LRM12N1X370S10BPT Is Used
Semiconductor test fixture indexer
A socket indexer stepping test heads across a small handler; a bottom-mount rail suits a fixture plate machined and tapped from its underside.
Fiber-optic coupler alignment slide
A manual adjustment slide that walks a fiber coupler along a 370 mm path while a power meter watches the coupling; precision grade P smooths the sweep.
Small-parts feeder on a packaging line
A light pusher indexing vials or connectors along a packaging machine bed, where a 12 mm rail fits the narrow frame of the machine section.
Is the Airtac LRM Miniature Linear Guide LRM12N1X370S10BPT the Right Guide?
Before ordering, run the series check. Substantial or overhung loads belong on LSH, whose catalogue publishes per-carriage dynamic, static and moment ratings - the sizing table LRM does not have. Short travel that demands crossed-roller stiffness points across to LGC. For this SKU, confirm: complete set with one carriage, 12 mm rail width, standard carriage length, 370 mm rail with S10 end offset, light preload B (a touch more compliant than medium grade C, but more forgiving of an imperfect mounting surface), precision accuracy P, bottom-mount fixing. Remember the mounting rules that protect travel accuracy: the surface should be ground or finish-milled, and where more than one carriage rides a rail, keep the datum edge on the same side for all of them. Most importantly, send the expected load and we will confirm the rating for this model - LRM publishes none.
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 LRM12N1X370S10BPT FAQ
In the box: one 370 mm stainless rail, 12 mm wide, with a single standard-length carriage mounted and pre-greased - a complete set, not a rail or carriage sold separately. Mounting is bottom-mount, so plan clearance beneath the rail for the fasteners and prepare your base accordingly; either long edge of the rail can serve as the datum face. The mounting surface should be ground or finish-milled to achieve the rated travel accuracy. Note the handling cautions too: never strike or drop the rail, and hold the carriage on an inclined rail so it cannot slide off under its own weight. Spares are best ordered as complete sets, since our carriage-only stock is just four SKUs.
Rail width 12 mm; rail length 370 mm with a 10 mm end-hole offset; one standard-length carriage; preload B, light; accuracy P, precision; bottom-mount fixing. Ambient limit: 80 C continuous, 100 C transient peaks. Lubrication: ships with Kyodo Yushi PS No. 2, re-grease every 100 km of travel or every 3 to 6 months - and note that a 200 mm stroke cycling once a second covers 100 km in roughly three weeks of continuous running, so the distance limit usually binds before the calendar does. Screw torque depends on the base material: M2 is rated 58.8 N.cm in steel, 39.2 in cast iron and 29.4 in aluminium, with M3 at 196, 127 and 98 N.cm. Load and moment ratings are not published for LRM; we confirm them for this model on request.
