Airtac LRM Miniature Linear Guide LRM12N1X195S10BPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X195S10BPT 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 LRM12N1X195S10BPT
This code stacks the two premium options into one set: LRM12N1X195S10BPT pairs the precision accuracy grade (P) with a bottom-mount rail (T). The hardware is a 12 mm wide stainless steel rail, 195 mm long, with a single standard-length recirculating-ball carriage, end holes offset 10 mm, and fixing from beneath so the top face of the rail stays clear - useful in metrology and optical builds where a flush surface matters as much as travel straightness.
Precision grade is specified when straightness of travel drives the machine's accuracy, and light preload (B) keeps that travel smooth rather than stiff. Balls are ISO 3290 G10, Japanese made - a grade for the balls only, never a rating for the assembly. A double-lip seal scrapes oil and excludes dust while an outer cover keeps larger debris off the seal strip. Keep ambient at or below 80 C, peaks to 100 C. Availability is a genuine strength here: 924 of the 988 sets we stock are LRM12, both accuracy grades and both mounting directions are held, so this combination is normally quick to ship. Load and moment ratings are not published for LRM - send the RFQ and we confirm the figures for this exact model.

Where the Airtac LRM Miniature Linear Guide LRM12N1X195S10BPT Is Used
Electronics test traverse
Carrying a lightweight probe head across connector rows on a functional-test fixture, with the guide recessed below the work surface on a bottom-mount rail.
Autosampler feed
Driving a small sampling needle between vial positions on a compact laboratory autosampler, with travel straightness set by the precision-grade rail.
Metrology jig building block
A precision-grade, bottom-mount rail kept on the shelf for building custom measuring jigs, where both accuracy and a flush top face are wanted.
Is the Airtac LRM Miniature Linear Guide LRM12N1X195S10BPT the Right Guide?
Two choices come bundled in this code, so check both are wanted: precision accuracy for travel straightness, and bottom-mount fixing for a rail fastened from beneath. Availability is good - 924 of the 988 stocked sets are LRM12, both grades and both mounting directions are held, and long carriages are stocked as deeply as standard ones. Price follows length rather than width, so cutting travel saves more than changing any other option on the code. Substantial or overhung loads belong on LSH, which publishes per-carriage dynamic, static and moment ratings you can size against; LRM does not, so we confirm the figure for the specific model. Short travel needing crossed-roller stiffness points to LGC. Confirm form, rail width, carriage length, count, rail length, preload, accuracy, mounting direction - and the load rating with us before ordering.
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 LRM12N1X195S10BPT FAQ
Rail width 12 mm, rail length 195 mm, one standard-length carriage, light preload (B), precision accuracy (P), bottom-mount rail. Screw torques: 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 limit is 80 C with peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months; the carriage ships with Kyodo Yushi PS No. 2. Load and moment ratings are not published for LRM - we confirm both per model on request.
It is a complete set: the 12 mm x 195 mm stainless steel rail and one standard-length carriage, pre-assembled and pre-greased, needing only screws to suit your base. Carriage-only codes in this series (with BK in them) are the opposite - no rail included, matched to a rail by a pairing code, and only a few are stocked. As with every LRM part, load and moment ratings are confirmed per model, so send the RFQ before finalising the design.
