Airtac LRM Miniature Linear Guide LRM12N1X150S10BH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X150S10BH 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 LRM12N1X150S10BH
LRM12N1X150S10BH is a complete matched set: one standard-length carriage on a 150mm stainless rail, 12mm wide, with end mounting holes offset 10mm from each rail end and fixing from the top. The carriage ships pre-filled with Kyodo Yushi PS No. 2 grease, so it is ready to run once you wipe off the rust-preventive oil and confirm an even film on the rail.
The B preload grade splits the difference on LRM: enough interference to settle the carriage under reversing loads, without the strict seating flatness the stiffest grade demands. Accuracy is H, the high grade. Note the maintenance arithmetic before you commit: at a 200mm stroke cycling once per second, the 100km re-grease interval passes in roughly three weeks of continuous running, so the distance limit binds long before the calendar's 3 to 6 months does. Inside the carriage are double-lip seals, an outer cover over the screws, and ISO 3290 G10 Japanese balls - that grade describes the balls only, not the guide assembly. The ambient limit is 80C with peaks to 100C. Load and moment ratings are absent from the LRM catalogue; we confirm them for this model via an RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X150S10BH Is Used
Benchtop adhesive dispensing gantry
A small glue-dot dispenser traversing a short line across a PCB panel, where light preload settles the head between direction changes without stiff, druggy travel.
Fiber-optic alignment slide
Fine positioning of a fiber chuck against a waveguide on a photonics lab bench, where smooth high-accuracy travel over 150mm supports repeatable coupling work.
Label applicator head slide
A light label head stepping along a packaging line infeed, wiping off old grease habits by scheduling re-grease on the 100km interval rather than the calendar alone.
Is the Airtac LRM Miniature Linear Guide LRM12N1X150S10BH the Right Guide?
Length, not width, drives the price across stocked LRM sets - the roughly $66 to $831 spread covers rail lengths from 40mm upward at only two rail widths - so trimming travel is the first lever on cost if the budget is tight. If the duty turns out heavier than light positioning, LSH publishes per-carriage dynamic, static and moment ratings that LRM does not, making it the safer sizing platform; and for short travel needing crossed-roller rigidity, LGC is the cross-over choice. Checklist: complete set form, 12mm rail width, standard carriage, one block, 150mm rail, light preload (B) and its smoother-running trade-off, H accuracy, top-mount direction, plus a load rating 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 LRM12N1X150S10BH FAQ
Key figures: 12mm rail width, 150mm rail length, one standard carriage, light preload (B), high accuracy (H), top-mount rail, 10mm end-hole offset. Screw torques run from 58.8 N.cm (M2 in steel) down to 29.4 N.cm (M2 in aluminium), and 196 to 98 N.cm for M3. The ambient temperature cap is 80C with transient peaks to 100C, and re-greasing is due every 100km of travel or every 3 to 6 months. Load and moment ratings do not appear in the LRM catalogue - we confirm the numbers for this model before you order.
Decide on load, not size. If the duty is heavy or the load sits on a cantilever, LSH is the defensible choice because it publishes per-carriage dynamic, static and moment ratings you can check; LRM publishes none, so its capacity is confirmed model by model through us. If the travel is short and crossed-roller rigidity is what the design needs, LGC fits better. This 150mm LRM12 set suits light-duty positioning in a tight envelope - send the load, stroke and mounting details and we will confirm the series and model.
