Airtac LRM Miniature Linear Guide LRM12L2X295S10CH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X295S10CH 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 LRM12L2X295S10CH
This ordering code describes a ready-to-run assembly: an LRM12 stainless-steel rail 295 mm long and 12 mm wide, with two long recirculating-ball carriages already fitted and fixed from above (no trailing T in the code, so top-mount). It needs nothing else to form a working axis.
Preload C is the medium grade and the most rigid of the three LRM offers: clearances under reversing loads stay small, at the cost of slightly higher drag and a greater demand on mounting-surface flatness. Accuracy grade H is the standard high grade. The carriages share the common LRM rail profile, so a same-spec replacement block fits the same rail later in the machine's life. The recirculating balls are Japanese-made to ISO 3290 G10 - a ball grade only, not a standard for the guide assembly - with ball retention for handling, double-lip sealing and an outer cover shielding the seal strip from larger debris. Keep ambient temperature at or under 80 C (transient peaks 100 C). Load capacity is confirmed per model before ordering: ask us and we will verify it through the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L2X295S10CH Is Used
Benchtop coordinate measuring fixture
Precision gauging stations on a 12 mm rail benefit from the medium preload's low play when the probe reverses direction between measured features.
Wire-forming and lead-cutting station
Guiding a light forming head over a 295 mm span, the twin long blocks resist the tipping that a single short block would allow at the ends of travel.
Laboratory dispensing robot
A syringe-dispensing axis with medium preload stays repeatable at the start and end of stroke, where a lighter preload grade would show more settle.
Is the Airtac LRM Miniature Linear Guide LRM12L2X295S10CH the Right Guide?
Sizing decision, both directions: step up to LSH when mass or an overhung moment is involved, because LSH carries published per-carriage dynamic, static and moment ratings in its catalogue and LRM has none - those figures end with a confirmation from us instead. Step across to LGC when the travel is short and stiffness per millimetre of stroke is the priority. Then tick the checklist for this SKU: complete set, 12 mm rail, long carriage, block count 2, rail 295 mm, preload C (rigid, least tolerant of flatness errors), accuracy H, top-mount mounting. Send the RFQ and we will confirm the load rating for this exact configuration.
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 LRM12L2X295S10CH FAQ
A 12 mm rail cut to 295 mm with a 10 mm end-hole offset, two long carriages, medium preload C, high accuracy H, top-mount fixing. Torque M3 screws to 196 N.cm in steel, 127 N.cm in cast iron and 98 N.cm in aluminium; M2 screws take 58.8, 39.2 and 29.4 N.cm in the same materials. Ambient must not exceed 80 C, with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months without mixing lubricant types. AirTAC publishes no basic dynamic or static load ratings, no moment ratings and no speed limit for LRM; we confirm the figures per model - add that request to your RFQ.
Choose LSH when the load is heavy or cantilevered, because it publishes per-carriage dynamic, static and moment ratings you can size against - LRM publishes none, so its load figures must be confirmed with us per model. Stay with LRM, as with this set, when the envelope is small and the duty is light-precision: you get a 12 mm rail, 295 mm of travel and two long carriages in the smallest practical section.
