Airtac LRM Miniature Linear Guide LRM12N1X495S10BHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X495S10BHT 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 LRM12N1X495S10BHT
This is a complete LRM12 set: one 12 mm wide stainless-steel rail, 495 mm long, carrying a single standard-length recirculating-ball carriage. The trailing T in the code means the rail is fixed from below, so screw heads sit inside the section and the upper face stays completely clear for carriage travel. It arrives as a matched, pre-greased assembly - nothing else to order.
Preload B removes the internal clearance lightly, so the carriage runs with minimal play without demanding a perfect deck. Inside, the balls are made in Japan to ISO 3290 G10 for roundness, a double-lip seal scrapes oil back and keeps dust out, and the outer cover shields the seal strip from larger debris while hiding the fixings. Note that 495 mm is close to half the 1005 mm catalogue full length for size 12, so this is a serious travel in a 12 mm envelope. LRM publishes no load or moment rating, so we confirm the figures for this exact model before you order - send the RFQ. Keep ambient temperature at or below 80 C, with peaks no higher than 100 C.

Where the Airtac LRM Miniature Linear Guide LRM12N1X495S10BHT Is Used
Compact pick-and-place head
A small benchtop gantry moving a suction head over a PCB tray. Bottom-mount fixing keeps the top of the 12 mm rail unobstructed, and light preload B keeps play out of the vertical move between picks.
Vision inspection camera slide
Carrying a compact camera across a 400 mm inspection window, the 495 mm rail leaves travel in reserve, while grade H accuracy holds the image plane steady frame to frame.
Micro-dosing pump carriage
A laboratory dosing head shuttling between reagent bottles. Re-grease every 100 km of travel or every 3-6 months - at a 200 mm stroke cycling once per second, the distance lands in about three weeks, so calendar time alone will not tell you when.
Is the Airtac LRM Miniature Linear Guide LRM12N1X495S10BHT the Right Guide?
Choose the form first: this is a set, so rail and carriage come together and no separate block purchase is needed. If the load is substantial or cantilevered, step up to AirTAC LSH instead - it publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not. For short travels where crossed-roller rigidity matters more than travel length, LGC is the cross-check worth costing. Then verify the checklist against your layout: set form, 12 mm rail width, standard carriage, one block, 495 mm rail, preload B, grade H accuracy, bottom-mount direction - and confirm the load rating with us before committing. Because bottom-mounting makes the mounting face itself the running reference, have that surface ground or finish-milled.
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 LRM12N1X495S10BHT FAQ
Rail width 12 mm, rail length 495 mm, one standard-length carriage, preload B (light), accuracy grade H, bottom-mount rail. Fastening torque: M2 screws 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 screws 196, 127 and 98 N.cm respectively. Ambient temperature must stay at or below 80 C with peaks no higher than 100 C, and re-greasing falls due every 100 km of travel or every 3-6 months. Load and moment ratings are not published for LRM - we confirm them for this model on request.
Pick LRM when the envelope is tight and the duty is light: a 12 mm rail with bottom-mount fixings suits a compact deck where a larger guide block simply will not fit. Pick LSH when the load is heavy, offset or cantilevered, because LSH publishes dynamic, static and moment ratings per carriage that you can size against on paper - LRM has no such table, so we verify its capacity model by model before you commit.
