Airtac LRM Miniature Linear Guide LRM12N2X95S10BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12N2X95S10BP 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 LRM12N2X95S10BP
The LRM12N2X95S10BP combines the two tightest options on this rail: P precision accuracy and B light preload, on a complete set built around a 95 mm stainless-steel rail that is 12 mm wide, carrying two standard carriages with top-mount fixing. It leaves us assembled and pre-greased, ready for a ground or finish-milled seat.
Handling is where miniature guides are won or lost: the ball retainer holds the ISO 3290 G10 Japanese-made balls captive, yet the maker warns that tilting the carriage onto a rail, or swapping it in a hurry, can still drop balls - a dummy rail is the careful way to service a spare. Store any unused set flat, coated with rust-preventive oil and sealed in its bag, away from heat and humidity. Never strike the rail; hidden dents shorten accuracy and life without visible marks. Standard and long LRM12 carriages share this rail profile, and the double-lip seal plus outer cover keep the raceway clean. Ambient must stay at or below 80 C, briefly to 100 C - keep it clear of oven doors and laser heads. Load and moment ratings are not published for LRM; we confirm them per model when you submit the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N2X95S10BP Is Used
AOI camera rail on a PCB inspector
A scanning camera darts back and forth over populated boards; the light preload lets the servo reverse sharply without the carriage lagging or drifting.
Web-edge sensor track on a label printer
The edge-sensor sled shifts across a 95 mm rail to follow different label web widths; P accuracy keeps the sensor position repeatable between changeovers.
Screw-driving bridge in a micro-assembly cell
Two carriages carry the driver bridge across fastener positions; the twin-block layout keeps the bit perpendicular to the part at both ends of the stroke.
Is the Airtac LRM Miniature Linear Guide LRM12N2X95S10BP the Right Guide?
Compare honestly before buying: LSH, the larger series, publishes the per-carriage dynamic, static and moment ratings that let you calculate margins with confidence - LRM has no such table, so for anything beyond light duty or with an overhung mass, LSH is the defensible choice. For short travel where crossed-roller rigidity wins, LGC is the cross-series alternative. Staying with this code, confirm: form - complete set with rail included; 12 mm rail width; standard carriage; two blocks; 95 mm rail length; preload B light; accuracy P; top-mount direction. If you will match a spare carriage later, the pairing code on the original part decides the fit - and since carriage-only stock here is only four SKUs, plan spares as special orders. Either way, the load rating for this exact SKU is confirmed with us before ordering.
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 LRM12N2X95S10BP FAQ
Use these: 12 mm rail width, 95 mm rail length, two standard carriages, preload B (light), accuracy P (precision), top-mount rail. Screw torques - M2: 58.8 N.cm steel, 39.2 N.cm cast iron, 29.4 N.cm aluminium; M3: 196, 127 and 98 N.cm. Ambient limit 80 C, transient peaks 100 C. Lubrication: ships with Kyodo Yushi PS No. 2; re-grease every 100 km of travel or every 3-6 months. What you will not find published for LRM: load, moment, running parallelism and speed - we confirm those per model, so put this SKU on an RFQ and we will reply with verified numbers.
Decide on the ratings, not the price. LSH gives you per-carriage dynamic, static and moment ratings in its catalogue, so a calculation stands on published numbers; LRM gives you a 12 mm-class miniature envelope and no published table at all, which is why every LRM order here ends with us confirming the load per model. Keep LRM for compact, light-duty precision motion like this 95 mm two-block set; take LSH when the mass is real or the load hangs off an arm; short travels wanting crossed-roller stiffness belong to LGC.
