Airtac LRM Miniature Linear Guide LRM12N2X295S10CHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X295S10CHT 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 LRM12N2X295S10CHT
The LRM12N2X295S10CHT is a complete AirTAC LRM miniature linear guide set: a 12 mm wide stainless-steel rail, 295 mm long, carrying two standard-length recirculating-ball carriages. This variant carries medium preload (code C) and high accuracy (code H), and the rail is drilled for bottom-mounting, so the fixing screws are reached from underneath the mounting surface. Both carriages ship already fitted on the rail and pre-filled with grease.
Inside each carriage, Japanese-made ISO 3290 G10 balls run in the raceways - the G10 grade applies to the balls themselves, not to the guide assembly as a whole. A double-lip seal scrapes oil back and excludes dust, while an outer cover shields the seal strip and hides the screw heads. The ball-retention design holds the balls during handling, but angling the carriage onto the rail or swapping it hastily can still drop balls, so keep any swap slow and deliberate. Ambient temperature must stay at or below 80 C, with short peaks to 100 C. Load and moment ratings are not published for LRM; we confirm the figures for this exact model before you order - send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X295S10CHT Is Used
PCB pick-and-place head
A compact SMT gantry moving a small vacuum head between component feeders and the placement position, where a 12 mm rail fits a slim crossbeam without stealing machine height.
Connector test fixture
An electronics lab sliding a probe carrier across rows of connectors on a test rig; bottom-mount fixing keeps the top surface flush for the fixture plate and wiring.
Microplate shuttle
A laboratory automation deck ferrying 96-well plates between a plate reader and a stacker, with light loads and smooth, repeatable strokes.
Is the Airtac LRM Miniature Linear Guide LRM12N2X295S10CHT the Right Guide?
Bottom-mounting suits frames where the top face must stay clear, but it means machining the fixings from below and reaching the screws blind - plan the access sequence before you cut metal. If your load is substantial or overhung, step up to AirTAC LSH, which publishes per-carriage dynamic, static and moment ratings you can size against; LRM publishes none of these. For short travels needing crossed-roller rigidity, LGC is the closer cross-series match. Before ordering, tick the checklist: complete set (rail plus two carriages), 12 mm rail width, standard carriage length, 295 mm rail, medium preload C - the rigid choice, but less forgiving of mounting-surface error - high accuracy H, bottom-mount direction. Confirm the load rating with us first; preload changes the running feel, not a published figure, because there is no published figure to change.
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 LRM12N2X295S10CHT FAQ
Yes - this is a complete matched set: one 295 mm stainless-steel rail, 12 mm wide, with two standard carriages factory-fitted and pre-greased. It is not a carriage-only part. If you later need a spare carriage, note that rails and carriages carry a pairing code that must match, and our carriage-only stock is thin - only four SKUs - so most spares are a special order. Quote the code from the original carriage when you ask.
Rail width 12 mm, rail length 295 mm, two standard-length carriages, medium preload (C), high accuracy (H), bottom-mount rail fixing. M3 mounting screws torque to 196 N.cm in steel, 127 N.cm in cast iron and 98 N.cm in aluminium. Ambient temperature is limited to 80 C with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months; grease quantities vary per model. Load, moment and running-parallelism ratings are not published for LRM - we confirm them for this exact model on request.
