Airtac LRM Miniature Linear Guide LRM12L2X395S10BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X395S10BP 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 LRM12L2X395S10BP
A top-mount miniature guide set: one stainless-steel rail 12 mm wide and 395 mm long, dressed with two long carriages. The P in the code is the accuracy grade - precision, a step above the high grade - which matters when the tracked position itself has to be repeatable across the full stroke, not merely when the carriage has to roll smoothly. Screws fasten through the top of the rail, the conventional arrangement that makes installation and alignment checks straightforward.
The long carriages give a longer bearing span than standard blocks on the same rail, useful wherever a load sits off to one side of the travel line. Inside each carriage, ISO 3290 G10 Japanese-made balls run in retained circuits, kept clean by a double-lip seal and an outer cover that also shields the seal strip. Keep ambient temperature at or below 80 C. Load and moment figures are not published for LRM; we confirm the specific values for this configuration by RFQ before you order.

Where the Airtac LRM Miniature Linear Guide LRM12L2X395S10BP Is Used
Calibration stage for a CMM fixture
A small measuring fixture that repositions gauge parts under a probe. Precision-grade travel keeps the reference line trustworthy across the 395 mm stroke, with two long blocks damping any pitch.
Micro-dispensing head on an electronics line
A fluid-dispensing head tracing glue paths across PCB assemblies. The long carriage stabilises the head over its nozzle, and top-mount screws make swapping the rail between fixtures quick.
Optics bench translator
A laser-lab translator sliding a mirror mount along an optical rail. Precision accuracy preserves beam alignment over the full travel; light preload keeps adjustment fluid during tuning.
Is the Airtac LRM Miniature Linear Guide LRM12L2X395S10BP the Right Guide?
Precision accuracy is what separates this SKU from its H-grade sibling: choose P when the application references the rail as a measuring datum, and save money with H when it only carries a payload. Everything else to verify: complete-set form, 12 mm rail width, long carriages, two per rail, 395 mm length, light preload B - the grade that rolls easiest, at the cost of a little rigidity versus C - and top-mount fixing. No pairing code applies; the set ships matched. Ask us to confirm the load and moment ratings for this exact model before you commit - LRM does not publish them.
Where the load is heavy or badly offset, LSH is the better tool because it publishes dynamic, static and moment ratings per carriage for formal sizing. For short travel needing crossed-roller stiffness, LGC fits instead. Note that rail length, not rail width, drives the price across stocked sets - trimming travel is the cheapest saving.
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 LRM12L2X395S10BP FAQ
In the box: one 12 mm stainless rail, 395 mm long, top-mount, fitted with two long carriages, light preload (B), precision accuracy (P). Grease at delivery is Kyodo Yushi PS No. 2; top up every 100 km or 3-6 months via the rear lubrication hole. Operating ambient: 80 C maximum, 100 C transient. Torque M2 screws to 58.8 N.cm (steel) and M3 screws to 196 N.cm. LRM publishes no load, moment or running-parallelism figures - request them from us per model and we confirm before dispatch.
Pick P when the rail doubles as a positional reference - metrology fixtures, optics work, anything where deviation along the travel is specified. Pick H when the guide only supports a moving load and the machine tolerances are looser; H costs less and is stocked just as widely. Preload, carriage length and rail mounting are all configurable independently of accuracy, so tell us the full picture and we will quote the right combination.
