Airtac LRM Miniature Linear Guide LRM12L2X295S10BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X295S10BP 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 LRM12L2X295S10BP
The LRM12L2X295S10BP is a complete miniature linear guide: a 12 mm wide stainless-steel rail, 295 mm long, carrying two long-body carriages with recirculating ball circulation and a 10 mm end-hole offset for the mounting screws. No trailing T in the code means the rail fixes from the top, screws through the crown, and one matched assembly arrives ready to bolt down.
The long carriages ride on more circulating balls than a standard body, which lengthens the bearing span and steadies any tipping component on the stage. Light preload B trims play without the drag of a heavier grade - a sensible match for precision P accuracy. The balls themselves are Japanese-made to ISO 3290 G10 for roundness and wear, a double-lip seal scrapes oil and excludes dust, and an outer cover shields the seal strip from larger debris. Keep ambient temperature at or below 80 C, with transient peaks no higher than 100 C. AirTAC publishes no load or moment rating for LRM, so include your load case with the RFQ and we confirm the figures for this exact configuration.

Where the Airtac LRM Miniature Linear Guide LRM12L2X295S10BP Is Used
PCB inspection XY stage
A compact imaging head sweeping over printed circuit boards on a 295 mm axis benefits from precision P accuracy and the steadier bearing span of two long carriages.
Microplate handling deck
Laboratory automation shuttling microplates between reader and stacker suits a 12 mm miniature guide running light, precise strokes without dominating the deck.
Laser diode alignment fixture
Aligning optics along a bench axis calls for smooth, play-free travel; light preload B keeps the carriage controllable while the precision grade holds the line.
Is the Airtac LRM Miniature Linear Guide LRM12L2X295S10BP the Right Guide?
Size 12 is the centre of gravity of the LRM range: 924 of the 988 stocked sets are LRM12, so a layout built on a 12 mm rail is the easiest configuration to satisfy. Because the price span of roughly $66 to $831 across stocked sets is driven by rail length and carriage count rather than width, trimming the 295 mm of travel is the lever worth pulling before upsizing. When the load is substantial or hangs on a cantilever, step up to LSH, which publishes per-carriage dynamic, static and moment ratings you can size against - the very figures LRM does not provide. Where travel is short and crossed-roller rigidity matters more than stroke, look across to LGC. Before ordering, confirm the full checklist: complete-set form, 12 mm rail width, long carriages, two blocks, 295 mm rail length, preload B light, accuracy P precision, top-mount fixing - and a load rating we verify per model when you enquire.
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 LRM12L2X295S10BP FAQ
Rail width 12 mm, rail length 295 mm, two long carriages, 10 mm end-hole offset, preload B (light), accuracy P (precision), top-mount rail fixing. Mounting screws follow the catalogue torques: M2 at 58.8 N.cm into steel, 39.2 N.cm into cast iron and 29.4 N.cm into aluminium; M3 at 196, 127 and 98 N.cm respectively. Ambient temperature must not exceed 80 C, with peaks to 100 C, and re-greasing falls due every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them for this model before you order.
One 295 mm stainless-steel rail with two long carriages fitted and pre-filled with Kyodo Yushi PS No. 2 grease - that is the whole set. Fasteners and mounting plates are your own, and a spare carriage is not part of this code; carriage-only SKUs are thin in the range, so a replacement usually means a special order. The ball-retention design keeps balls captive during handling, but the maker warns that angling the carriage onto the rail or swapping it hastily can still drop balls - a dummy rail makes carriage changes safe.
