Airtac LRM Miniature Linear Guide LRM12L1X195S10BHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X195S10BHT 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 LRM12L1X195S10BHT
LRM12L1X195S10BHT is the bottom-mount version of the 12 mm LRM set with a 195 mm stainless steel rail, one long recirculating-ball carriage and light preload B. The trailing T changes how the rail is fixed: fastening happens from beneath, so the top face stays clear and the screw line is hidden inside the assembly - handy where nothing may project above the rail. Accuracy is grade H and the end holes carry a 10 mm offset.
Because the fasteners sit under the rail, the outer cover matters double: it shields the exposed seal strip and keeps larger debris out of the screw line. The balls in the circuit are ISO 3290 G10, Japanese made, held by the ball-retention design - though the manufacturer is clear that inserting the carriage at an angle or swapping it hastily can still drop balls, so a dummy rail is worth planning for. Keep ambient temperature at or below 80 C with peaks no higher than 100 C. The re-grease interval of 100 km arrives sooner than it sounds: a 200 mm stroke cycling once per second covers it in about three weeks of continuous running, so high-cycle machines bind on distance long before the calendar. Load and moment ratings are confirmed per model - request them through the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X195S10BHT Is Used
Desktop pick-and-place gantry
The y-axis of a small SMT prototyping machine moving a vacuum head between reel and PCB, with the guide set into a slot so no fasteners rise above the rail.
Laser optics alignment slide
A focusing lens carrier on a benchtop laser rig, where the free-running light preload makes fine alignment adjustments easy to trim by hand.
Autosampler transport rail
A syringe head travelling along a compact autosampler in a water-testing laboratory, re-greased on the 100 km interval between scheduled services.
Is the Airtac LRM Miniature Linear Guide LRM12L1X195S10BHT the Right Guide?
When the load is heavy or overhung, step up to LSH - that series publishes dynamic, static and moment ratings per carriage you can calculate against, whereas LRM gives you no published numbers to work from. For short travels that need crossed-roller stiffness, look at LGC instead. Your checklist for this code: complete set form, 12 mm rail, long carriage, one block, 195 mm rail length, preload B (smooth but less rigid than C - the trade-off is free motion versus installed stiffness), accuracy H, bottom-mount fixing, which must agree with the mating surface you designed. Confirm the load rating with us before ordering; an RFQ gets you the datasheet figure for this exact model.
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 LRM12L1X195S10BHT FAQ
Rail width 12 mm, rail length 195 mm, one long carriage, preload B (light), accuracy H, bottom-mount (T). Screw torque: M2 - 58.8 N.cm steel, 39.2 cast iron, 29.4 aluminium; M3 - 196, 127, 98 N.cm. Factory grease is Kyodo Yushi PS No. 2; re-grease every 100 km of travel or every 3 to 6 months, whichever comes first. Ambient limit is 80 C with 100 C transient peaks. Basic dynamic and static load ratings and allowable moments are not published for LRM; we confirm them per model via RFQ.
The T code fixes the rail from beneath, keeping the top surface clear and the screw line covered by the outer cover - a clean arrangement inside a channel or under a plate. Two handling cautions: on an inclined or vertical rail the carriage can slide off under its own weight, so hold it; and although the ball retainer helps, fitting the carriage at an angle or swapping it quickly can still drop balls, so work carefully and consider a dummy rail for carriage changes.
