Airtac LRM Miniature Linear Guide LRM12N1X495S10BPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X495S10BPT is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriage. 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 LRM12N1X495S10BPT
This bottom-mount version of the LRM12 set carries a trailing T in the code: the rail is fixed from underneath, so the screw heads sit on the far side and the top face stays completely unbroken. You get the same 12 mm wide, 495 mm long stainless rail with a single standard recirculating-ball carriage, light preload B and precision accuracy P as the top-mount variant - only the fixing direction differs.
Mounting quality decides how accurately a guide like this actually runs: the catalogue calls for a ground or finish-milled seat, and lists the counterbore depth, throat and edge-radius values as a set of five rows per size, so plan the machining before the rail arrives. The carriage ships pre-filled with Kyodo Yushi PS No. 2 grease and needs topping up every 100 km of travel or every 3 to 6 months - on a 200 mm stroke cycling once per second, the distance comes round in roughly three weeks of continuous running, so the calendar rarely binds first. Load ratings are confirmed only per model; ask us with this exact code and we will return the figure.

Where the Airtac LRM Miniature Linear Guide LRM12N1X495S10BPT Is Used
Laboratory pipetting gantry
A compact liquid-handling head traversing microplates keeps a flush top surface, because no screw heads protrude above the rail to snag tubing or tips.
Metrology fixture slide
Precision-grade travel accuracy supports a measuring probe carriage, and either rail edge can serve as the datum face, keeping machine layout flexible.
Cable flex-life test rig
Continuous-flex cable testing over a long stroke uses the full 495 mm travel, and the clean top face lets the carrier track lie flat against the rail.
Is the Airtac LRM Miniature Linear Guide LRM12N1X495S10BPT the Right Guide?
LRM fits here when the envelope is tight and the duty is light. If the load is heavy or cantilevered, move up to LSH, which publishes dynamic, static and moment ratings per carriage so you can run a proper sizing calculation - something LRM's data does not allow. If travel is short but stiffness is everything, LGC's crossed-roller construction is the better cross-series choice. Before ordering: confirm the set form, 12 mm width, standard carriage, single carriage, 495 mm length, preload B against its trade-off (light slides easiest but flexes more under offset loads), accuracy P, bottom-mount direction - and get the load rating confirmed with us.
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 LRM12N1X495S10BPT FAQ
The T suffix fixes the rail from below, leaving the running surface free of protruding screws - useful wherever something must slide or sit flush above the rail. Machine the seat to a ground or finish-milled finish, because achieved travel accuracy depends on it. This set is 12 mm wide, 495 mm long, with one standard carriage, light preload and precision accuracy. Load and moment figures are not published for LRM; we confirm them per model.
Rail width 12 mm, rail length 495 mm, stainless-steel rail, one standard carriage, preload grade B (light), accuracy grade P (precision), bottom-mount fixing. Maximum ambient temperature 80 C with 100 C transient peaks. Lubricate with Kyodo Yushi PS No. 2 and top up every 100 km or every 3 to 6 months. M3 fixing screws take 196 N.cm into steel. No load rating is published - request confirmation from us before committing to the design.
