Airtac LRM Miniature Linear Guide LRM12L2X295S10AHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X295S10AHT 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 LRM12L2X295S10AHT
The trailing T in LRM12L2X295S10AHT changes how the rail is fixed: this is a bottom-mount set, where bolts reach the rail through its base, leaving the top face clear for the carriages and any tooling bolted to them. You get a 295 mm length of 12 mm wide stainless-steel rail with two long recirculating-ball carriages fitted, preload-free (grade A) and machined to high accuracy H.
Choose bottom-mount when the machine table hides the rail's top edge or when screw heads cannot run across the rail surface - a slot in a compact base plate, for instance. Note the handling caveat: the ball retainer helps, but tilting a carriage onto the rail or swapping it hastily can still drop balls, so work deliberately and consider a dummy rail. The carriage carries a double-lip seal, an outer cover and Japanese ISO 3290 G10 balls (a grade applying to the balls only). Ambient temperature must stay at or below 80 C, with short excursions to 100 C. Load and moment ratings are not published for LRM; send the RFQ and we confirm them for this configuration.

Where the Airtac LRM Miniature Linear Guide LRM12L2X295S10AHT Is Used
Lab gantry base slide
A small three-axis laboratory gantry takes its Z-column base on this bottom-mounted rail, so no screw heads interrupt the surface the carriage sweeps.
Measuring instrument retrofit
Replacing a worn dovetail slide in an older height gauge or profilometer with a 12 mm rail brings smoother, longer-wearing travel, and fixing through the rail base suits a housing tapped from below.
Compact dosing head
A micro-dosing pump head on a small packaging machine rides two long carriages, holding the nozzle steady through each 295 mm fill cycle.
Is the Airtac LRM Miniature Linear Guide LRM12L2X295S10AHT the Right Guide?
If the load is significant or sticks out on a cantilever, choose AirTAC LSH instead - LSH publishes the dynamic, static and moment ratings per carriage that LRM omits, so an overhung design can be checked numerically. For short, stiff travels, LGC's crossed rollers are the better fit. On this set, confirm each item: complete-set form with the rail supplied, 12 mm rail, long carriage, two blocks on one rail, 295 mm length, preload A (adding grade B or C stiffens the carriage but increases drag), accuracy H, bottom-mount rail direction, and a load rating confirmed with us per model. Bottom-mount also demands holes in the table that reach the rail base - plan them before machining.
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 LRM12L2X295S10AHT FAQ
Confirmed figures: 12 mm rail width, 295 mm rail, two long carriages, no preload (grade A), high accuracy H, bottom-mount rail and a 10 mm end offset. Screw torque: M2 at 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 at 196, 127 and 98 N.cm respectively. Ambient limit is 80 C with brief excursions to 100 C, and lubrication is due every 100 km of travel or every 3 to 6 months. Basic dynamic, static and moment ratings are not published for this series; request them per model through the RFQ and we confirm before you commit.
The set includes the 295 mm stainless-steel rail with both long carriages fitted, pre-filled with Kyodo Yushi PS No. 2 grease. Because the rail is bottom-mount, plan machine holes that let bolts reach the rail base from underneath and keep the top surface unobstructed. Spare carriages are rarely held on the shelf - we stock only four carriage-only part numbers - so if a future swap is likely, order a spare now or keep a dummy rail for safe refitting, since balls can drop if a carriage is tilted onto the rail.
