Airtac LRM Miniature Linear Guide LRM12L2X295S10BPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X295S10BPT 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 LRM12L2X295S10BPT
LRM12L2X295S10BPT is a complete miniature linear guide set: one 295 mm stainless-steel rail, 12 mm wide, carrying two long (L) recirculating-ball carriages. The set arrives assembled, with end fixing holes offset 10 mm from each rail end (S10) and bottom-mount fixing (trailing T), so the screws sit beneath the rail and the top surface stays clear.
Light preload (B) keeps sliding drag and stiction low, which matters where a small motor or a hand knob must move the stage smoothly, while precision accuracy (P) tightens travel tolerance for repeatable positioning. The long carriage spreads its balls over a greater span, lengthening the effective bearing base against pitching. Inside, the balls are Japanese-made ISO 3290 G10 grade (the grade applies to the balls only, not the assembly), held by the ball-retention design and wiped by a double-lip seal beneath an outer cover. Ambient temperature must stay at or below 80 C, with brief peaks to 100 C. Size 12 is by far the deepest stocked part of the LRM range, so this configuration is normally the quick-ship choice. Load and moment ratings are not published for LRM; we confirm them for this exact model - include it in your RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L2X295S10BPT Is Used
Semiconductor inspection microscope stage
A 12 mm rail under a small optics-carrying stage keeps the profile shallow inside a microscope's light path, and the precision grade suits repeatable repositioning of the sample.
SMT pick-and-place head
Twin long carriages on one rail resist tipping when the head lifts and places small components, and light preload keeps drive losses down on a lightly powered axis.
Benchtop laser engraver gantry
Bottom-mount fixing leaves the rail's top face flush for clamping workpieces or routing a belt in a compact engraver frame.
Is the Airtac LRM Miniature Linear Guide LRM12L2X295S10BPT the Right Guide?
Compare upward first: if the load is substantial or hangs off the carriage, AirTAC LSH is the series that publishes per-carriage dynamic, static and moment ratings you can size against - LRM publishes none of these, so cantilevered or heavy duties belong on LSH. Compare across: for very short travel where crossed-roller rigidity beats ball recirculation, LGC is the better fit. For this set, confirm: complete-set form (rail included), 12 mm rail width, long carriage, two blocks, 295 mm rail, light preload B - smoother but with more play under reversing loads than C - precision P accuracy, and bottom-mount fixing. Before ordering, confirm the load rating with us 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 LRM12L2X295S10BPT FAQ
Rail width 12 mm, rail length 295 mm, two long carriages, light preload (B), precision accuracy (P), bottom-mount rail, 10 mm end-hole offset. Fixing torque: M3 screws 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium (M2: 58.8, 39.2 and 29.4 N.cm respectively). Ambient limit 80 C with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months, never mixing lubricant types. Basic dynamic and static load ratings, allowable moments and speed limits are not published for LRM; we confirm the relevant figures per model before you order - request them with your RFQ.
The complete set: one 295 mm stainless-steel rail with both long carriages pre-fitted and pre-greased with Kyodo Yushi PS No. 2, so the box contains a working axis rather than a parts kit. Before first use, wipe off the rust-preventive oil and apply lubricant. Carriages are not drop-proof despite the ball-retention design: present them straight onto the rail, and hold the assembly flat, since a carriage on an inclined rail can slide off under its own weight.
