Airtac LRM Miniature Linear Guide LRM12L1X295S10BH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X295S10BH 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 LRM12L1X295S10BH
LRM12L1X295S10BH is a complete AirTAC LRM miniature linear guide: one 295 mm stainless-steel rail, 12 mm wide, drilled for top-mount screws with a 10 mm end-hole offset, and a single long (L) recirculating-ball carriage factory-fitted to it. The set arrives pre-greased and preloaded to light grade B, ground to high accuracy H. Bolt it to a ground or finish-milled face to realize the rated travel accuracy.
The long carriage is the working feature here: more recirculating balls sit under the load and the bearing span stretches out, which steadies any head that wants to tip. The balls themselves are Japanese-made to ISO 3290 G10 - a grade that covers the balls only, not the guide assembly - held in by ball retention so they stay put during handling, wiped by a double-lip seal and shielded by an outer cover over the screw line. Keep ambient heat at or below 80 C with peaks no higher than 100 C. AirTAC publishes no load or moment ratings for LRM, so tell us your application through the RFQ and we confirm the figures for this exact model. It helps that LRM12 is the most widely carried size in the range, and long carriages are offered as deeply as standard ones, so this configuration is well supported.

Where the Airtac LRM Miniature Linear Guide LRM12L1X295S10BH Is Used
Compact glue-dispensing XY stage
A two-axis dispensing head on a small electronics assembly bench, where the long carriage keeps a slightly overhung nozzle steady along the 295 mm sweep.
Optical inspection fixture
Carrying a small camera or probe across a PCB sample under a benchtop microscope, with high accuracy H keeping image registration repeatable pass after pass.
Laboratory microplate handler
A single-axis pusher stepping microplates between stations in a compact analyzer; light preload keeps the motion easy on a small stepper motor.
Is the Airtac LRM Miniature Linear Guide LRM12L1X295S10BH the Right Guide?
Size this part both ways before you commit. If the load is substantial or cantilevered, step up to AirTAC LSH: its catalogue publishes per-carriage dynamic, static and moment ratings you can size against, numbers LRM never lists, so LRM capacity is always confirmed by us per model. If travel is short and the job wants crossed-roller rigidity, LGC is the closer match. Match-checklist for this SKU: complete set (rail included), 12 mm rail width, long carriage, one block on the rail, 295 mm rail length, light preload B - the smooth-running choice that leaves a trace of internal play - high accuracy H, and top-mount fixing. Confirm the load rating with us through the RFQ 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 LRM12L1X295S10BH FAQ
Rail width 12 mm; rail length 295 mm; one long (L) carriage; end-hole offset 10 mm; preload B (light); accuracy H (high); top-mount rail fixing. M3 mounting screws take 196 N.cm into steel, 127 N.cm into cast iron and 98 N.cm into aluminium. Ambient temperature must not exceed 80 C with transient peaks to 100 C, and re-greasing is due every 100 km of travel or every 3 to 6 months. AirTAC publishes no load or moment ratings for the LRM series, so we confirm those figures for this exact model on request.
Pick LRM when the envelope is tight and the duty is light - this set gives a 12 mm rail and a 295 mm stroke in a small footprint. Move to LSH when the load is substantial or cantilevered: LSH publishes dynamic, static and moment ratings per carriage that you can size against, while LRM has none, so capacity is confirmed by us model by model. If travel is short and you need crossed-roller rigidity, compare LGC. Either way, send the RFQ and we will check the figures for your build.
