Airtac LRM Miniature Linear Guide LRM12N2X295S10CPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X295S10CPT 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 LRM12N2X295S10CPT
Order the LRM12N2X295S10CPT and you receive a finished assembly: one 295 mm stainless rail, 12 mm across, with a pair of standard carriages already seated on it, each pre-filled with grease. The carriage count is the useful part of this configuration - two blocks sharing one rail resist tipping moments along the direction of travel, which matters on any stage carrying an overhanging instrument. Accuracy is precision grade P, preload is medium (C), and the rail mounts from underneath.
Bottom-mount fixing leaves the rail's top face clear for workpieces or brackets, but it demands screw bosses machined into the base structure and reached blind - plan the sequence before cutting metal. Precision grade P is the tighter of LRM's two accuracy classes, so pair it with a ground or finish-milled mounting surface, and put the datum face on the same side for both carriages. The balls in the recirculating circuit are Japanese-made ISO 3290 G10 - a grade for the balls alone. Double-lip seals and an outer cover protect the raceways from oil loss and debris. Ambient temperature must not exceed 80 C, with brief excursions to 100 C. No load or moment figures are published for LRM; we verify them for this exact SKU on RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X295S10CPT Is Used
Laser collimation stage
An optics lab translating a collimating lens along the beam axis in fine increments; precision grade and twin blocks help hold tilt down over the stroke.
Wafer inspection micro-stage
A small inspection stage carrying a sensor head over die regions on a test chuck, where bottom-mount fixing keeps the working plane unobstructed.
Reagent dosing head
An in-vitro diagnostics analyzer moving a dispensing head across a row of reaction wells with smooth, light strokes and consistent positioning.
Is the Airtac LRM Miniature Linear Guide LRM12N2X295S10CPT the Right Guide?
Choose this SKU when precision travel is needed under a structure that can only be fixed from below, and the load stays light. When the mass becomes substantial or hangs off a cantilever, LSH is the series to move to - it lists per-carriage dynamic, static and moment ratings you can calculate against, which LRM does not publish at all. Short travel with a rigidity requirement points across to LGC and its crossed rollers. Run the checklist: complete set with two standard carriages, 12 mm rail width, 295 mm rail length, medium preload C (stiff but sensitive to surface quality), accuracy P, bottom-mount direction. Finally, confirm the load rating with us before ordering - there is no catalogue figure to fall back on.
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 LRM12N2X295S10CPT FAQ
Rail width 12 mm, rail length 295 mm, two standard carriages, medium preload (C), precision accuracy (P), bottom-mount rail fixing. Mount on a ground or finish-milled surface for the rated travel accuracy, and use the same datum side for both carriages. M3 screws: 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium. Ambient limit 80 C with transient peaks to 100 C; re-grease every 100 km of travel or every 3 to 6 months, quantity per model. Load and moment ratings are not published for LRM - we confirm them for this exact model.
The honest answer is that LRM carries no published load, moment or speed figures, so the question is settled per model rather than from a table - send the RFQ and we confirm the capacity of this exact 295 mm, twin-carriage set. As a rule for the family, LRM is the light-duty, tight-space end of the range. If your mass is substantial, overhung, or you need numbers to calculate with today, AirTAC LSH publishes dynamic, static and moment ratings per carriage. For short strokes where rigidity matters more than travel, LGC with crossed rollers is the alternative.
