Airtac LRM Miniature Linear Guide LRM12N2X295S10BH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X295S10BH 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 LRM12N2X295S10BH
The LRM12N2X295S10BH is a complete AirTAC LRM set: a 295 mm stainless-steel rail, 12 mm across, top-mount fixing, carrying two standard-length carriages set to light preload B. Unlike the A-grade sets, preload B removes a little internal clearance, so play under reversing loads tightens up at the cost of slightly higher running drag.
Two blocks sharing one rail spread the carried mass and resist tipping along the travel direction. The recirculating balls are Japanese-made to ISO 3290 G10 for roundness and wear life; ball retention holds them in the carriage during handling, though a square, unhurried fit is still the rule since a hasty swap can drop balls. A double-lip seal works with an outer cover to keep lubricant in and debris out. Keep the surroundings at or below 80 C. On upkeep: the 100 km re-grease interval arrives sooner than it sounds - a 200 mm stroke cycling once per second covers 100 km in roughly three weeks of continuous running, so distance binds before the calendar does. Load and moment ratings are not published for LRM; send an RFQ and we will confirm the figures for this exact preload and accuracy combination.

Where the Airtac LRM Miniature Linear Guide LRM12N2X295S10BH Is Used
Small engraving head slide
A light-duty engraving or marking head reverses direction constantly; light preload B tightens out the play that would otherwise show at each stroke reversal.
Vision inspection gantry axis
A benchtop camera gantry over a PCB line, where two preloaded carriages on a 295 mm rail keep the lens plane steady through stop-start moves.
Optical bench tuning stage
Fine positioning of a mirror or beamsplitter mount, where light preload damps float without stiffening the stage beyond easy manual adjustment.
Is the Airtac LRM Miniature Linear Guide LRM12N2X295S10BH the Right Guide?
Decide the preload first, because it is the real trade in this SKU: B light preload firms up reversed-motion play but adds drag versus the A option, and LRM offers no heavier grade than B. Then check the rest - complete set form, 12 mm rail width, standard carriages, two of them, 295 mm rail, accuracy H, top-mount, and the load figure, which you must confirm with us because the series publishes no ratings. If your mass or overhang goes beyond light duty, LSH is the step up: its catalogue gives per-carriage dynamic, static and moment ratings for real sizing. For a short axis where crossed-roller rigidity beats stroke, LGC is the cross-series alternative. Worth noting: long carriages are stocked almost as deeply as standard ones, so if tipping becomes a concern later, switching to an L-suffix carriage costs little in availability.
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

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 LRM12N2X295S10BH FAQ
Rail width 12 mm, rail length 295 mm, two standard carriages, preload B (light), accuracy H (high), top-mount rail. Screw torques are 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium for M2, and 196, 127, 98 N.cm for M3. Ambient temperature must stay at or below 80 C with peaks to 100 C; re-grease every 100 km of travel or every 3 to 6 months. Note that LRM publishes no dynamic, static or moment ratings - we confirm the load figures for this exact model when you enquire.
You receive the complete axis: the 295 mm stainless-steel rail with both preloaded standard carriages fitted. Not included: spare carriages, rail-only sections or bolt caps (a bolt-cap pack exists in the catalogue for LRM9 but is order-only, and we stock none of these extras). Carriage-only stock is limited to a handful of SKUs, so if you expect to swap blocks in the field, add a spare set or a dummy rail to the order and fit carriages squarely to avoid dropping balls.
