Airtac LRM Miniature Linear Guide LRM12L2X195S10BPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X195S10BPT 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 LRM12L2X195S10BPT
LRM12L2X195S10BPT combines the two premium choices in one code: accuracy grade P for tighter tolerances, and a bottom-mount rail - the trailing T - that fixes from below through the machine table. The set itself is a 12 mm wide stainless rail, 195 mm long, carrying two long recirculating-ball carriages at light preload, delivered assembled and pre-filled with Kyodo Yushi PS No. 2 grease.
Fixing from below leaves the rail's top face uninterrupted, which matters when a cable harness or a guard runs along the travel path. Because grade P only shows its value on a well-prepared seat, machine the mounting faces ground or finish-milled, and put the datum edge on the same side for both carriages. Keep the ball-retainer's limits in mind when servicing: it holds the ISO 3290 G10 balls during normal handling, but an angled insertion or a rushed swap can still drop balls, and only a handful of carriage-only SKUs exist in our stock, so plan swaps with a dummy rail. Ambient temperature must stay at or below 80 C, peaks to 100 C. The 100 km re-grease interval binds before the calendar on fast machines: a 200 mm travel cycling once per second covers 100 km in roughly three weeks of continuous running. Load and moment ratings are not published for LRM; we confirm them per model - include this code in your RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L2X195S10BPT Is Used
Wafer-handling sub-stage
A semiconductor test cell builds a small wafer-transport sub-stage on this bottom-mount set, keeping the top surface clear for the wafer boat while the precision grade holds the transfer path true.
Laser diode test fixture with top-routed harness
A photonics test station routes its sensor harness along the top of the travel; because the rail fixes from below, the harness never crosses a screw head or the rail foot.
Enclosed microscope inspection stage
A quality lab fits an inspection microscope's sample stage inside a protective shroud; the double-lip seals and outer covers on both long carriages keep dust out where the enclosure is opened for loading.
Is the Airtac LRM Miniature Linear Guide LRM12L2X195S10BPT the Right Guide?
Specify this code when you need the precision grade and the fixing screws must live underneath the table. For heavier or cantilevered loads, move to LSH - its catalogue publishes the per-carriage dynamic, static and moment ratings you can calculate against, which LRM deliberately does not, so capacity here is confirmed per model through us. For short travel where crossed-roller rigidity beats travel length, LGC is the alternative to price. Checklist: set form (rail included), 12 mm rail width, long carriage, two carriages, 195 mm rail length, preload B (light - compliant and easy to mount rather than the stiffer C), accuracy P, bottom-mount direction, and a load-rating confirmation from us before the order is placed. This configuration is stocked, so no special build is needed.
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 LRM12L2X195S10BPT FAQ
Rail width 12 mm; rail length 195 mm; two long carriages; preload B (light); accuracy P (precision); bottom-mount rail with a 10 mm end-hole offset. Torques: M2 screws - 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 screws - 196, 127 and 98 N.cm. 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 specific model before ordering.
Choose the trailing-T version when screws cannot be reached from above or when the top face must stay clear - for a flush rail in a slot or a harness running over the travel. Accuracy grade P adds tighter tolerances than grade H, but only pays off on ground or finish-milled mounting surfaces with a consistent datum side. Compared with LSH: LSH publishes per-carriage dynamic, static and moment ratings you can size against, while LRM publishes none and its capacity is confirmed per model through us - so if the load is substantial or cantilevered, LSH is the sounder engineering choice. For short travel needing crossed-roller rigidity, price LGC alongside both.
