Airtac LRM Miniature Linear Guide LRM12N1X650S12.5AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X650S12.5AH 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 LRM12N1X650S12.5AH
LRM12N1X650S12.5AH is a complete miniature linear guide: a 650 mm long, 12 mm wide stainless-steel rail with one standard-length recirculating-ball carriage mounted on it. The S12.5 segment sets a 12.5 mm end-hole offset, so check your base-plate hole pattern against this dimension before machining.
Preload grade A (none) gives the freest-running travel in the range, trading stiffness for smoothness, while accuracy grade H is high. Japanese-made balls to ISO 3290 G10 - that grade applies to the balls only - recirculate behind a double-lip seal, and an outer cover keeps screws and seal strip out of the debris path. Do not slide the carriage off quickly or at an angle; the retainer reduces, but does not remove, the risk of dropped balls. Ambient temperature must stay at or below 80 C, peaking no higher than 100 C. AirTAC publishes no load or moment ratings for LRM, so send the RFQ and we confirm the figures for this exact model.

Where the Airtac LRM Miniature Linear Guide LRM12N1X650S12.5AH Is Used
Connector pin assembly slide
A half-metre-plus indexing slide presenting PCB connectors to an insertion head; the 650 mm rail covers long parts trays without splicing, and grade H keeps pitch alignment honest.
Laser focus axis
A focusing carriage riding the length of a marking or engraving bench; preload A gives friction-free travel while the 12.5 mm end offset helps match the machine's existing hole pattern.
Chromatography autosampler axis
The sampling arm of a benchtop HPLC sweeping across a vial tray; smooth, lightly loaded travel and the double-lip seal suit the clean but daily-cycled demands of a laboratory.
Is the Airtac LRM Miniature Linear Guide LRM12N1X650S12.5AH the Right Guide?
Substantial or cantilevered loads should be sized on AirTAC LSH, which publishes per-carriage dynamic, static and moment ratings - the engineering numbers LRM leaves out. Where travel is short and crossed-roller rigidity is the priority, LGC is the alternative. Ordering this 650 mm set, work through: complete-set form, 12 mm rail width, standard carriage, single carriage, preload A (none) and its clearance trade-off, high accuracy (H), top-mount fixing, a matching pairing code for any future spare carriage, and a load rating confirmed with us first. At 650 mm this is among the longer stocked rails; designs needing more can go to 995 mm from stock, with spliced two-section sets available to order beyond that.
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 LRM12N1X650S12.5AH FAQ
Rail width 12 mm; rail length 650 mm; one standard-length carriage; preload grade A (none); accuracy grade H (high); top-mount rail; end-hole offset 12.5 mm. Fix with M3 screws at 196 N.cm into steel, 127 N.cm into cast iron or 98 N.cm into aluminium. The ambient temperature limit is 80 C, transient peaks 100 C. Grease is Kyodo Yushi PS No. 2 from the factory; refresh every 100 km of travel or every 3 to 6 months. AirTAC publishes no load, moment or speed ratings for LRM - request them and we confirm for this exact model.
Yes. Stocked LRM12 rails run up to 995 mm and the catalogue lists a 1005 mm full-length option; beyond that, spliced two-section rails extend the travel further and can be ordered in, accuracy grade H only. Spliced sets assemble by matching the joint marks and pairing the engraved serials, such as A001 with B001. Whatever length you land on, confirm the load rating with us for the exact model before finalising the design.
