Airtac LRM Miniature Linear Guide LRM12N1X295S10BHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X295S10BHT 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 LRM12N1X295S10BHT
LRM12N1X295S10BHT combines two choices in one code: preload B, which takes up the ball clearance for a firmer, play-free feel, and a trailing T, meaning the 12 mm stainless-steel rail bolts down from below through a machined seat. The rail is 295 mm long with a 10 mm end-hole offset and carries one standard-length carriage; accuracy grade H is the standard LRM finish.
This is the version to specify for a hidden axis where lost motion would show up in the readout but you cannot put screw heads on the visible face. Handle the carriage with care: the ball-retention design helps, yet inserting it at an angle or swapping it quickly can still drop balls, and on an inclined rail the carriage can slide off under its own weight - a dummy rail makes field swaps safer, though our carriage-only stock is thin, so spares are usually ordered specially. The ambient limit is 80 C with transient peaks to 100 C. No load or moment rating is published for LRM; we confirm the figure for this exact code through your RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X295S10BHT Is Used
Optical breadboard delay line
A delay line built under an optical breadboard keeps the beam path clear because the rail fixes from beneath; preload B removes the lost motion that would blur a position readout.
Semiconductor test socket slide
A benchtop station sliding a device under a probe head on a small handler benefits from a play-free carriage, so the repeat position does not drift between contact cycles.
Compact labeling machine rebuild
Rebuilding the table slide of a small labeling machine, a bottom-mount rail leaves the working face unbroken where labels and product pass over.
Is the Airtac LRM Miniature Linear Guide LRM12N1X295S10BHT the Right Guide?
Choose this code when the seat sits under an overhang and lost motion matters more than absolute seat flatness - preload B stiffens the feel while H accuracy keeps the finish standard. If the load turns out to be substantial or cantilevered, step up to LSH: it publishes per-carriage dynamic, static and moment ratings you can design against, which LRM does not. Short travel with a demand for crossed-roller rigidity points to LGC instead.
Confirm against the checklist: complete set, 12 mm rail width, 295 mm rail length, one standard carriage, preload B (light - stiffer than A, more forgiving than C), accuracy H, bottom-mount fixing, 10 mm end-hole offset. LRM12 is the best-stocked width by a wide margin - 924 of 988 stocked sets - so this configuration ships from a deep position. Confirm the load rating with us before committing.
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 LRM12N1X295S10BHT FAQ
Rail width 12 mm, rail length 295 mm, 10 mm end-hole offset, one standard-length carriage, light preload (code B), accuracy grade H, bottom-mount holes. Torque the fixing screws: M3 at 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium; M2 at 58.8, 39.2 and 29.4 N.cm. Keep ambient temperature at or below 80 C (peaks 100 C). Factory-filled with Kyodo Yushi PS No. 2, topped up every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM; we confirm them per model via the RFQ.
The box holds the matched set: the 295 mm stainless-steel rail with its single standard carriage already fitted and pre-greased. No spare carriage, no rail-only section and no pairing code are involved. For a future replacement, remember the carriage-only range we keep on the shelf is only a handful of SKUs, so expect a special order; and although the ball-retention design holds the Japanese-made ISO 3290 G10 balls in place during handling, fitting a carriage onto a rail at an angle or quickly can still drop balls - work slowly or use a dummy rail.
