Airtac LRM Miniature Linear Guide LRM12L1X520S10AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X520S10AH 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 LRM12L1X520S10AH
This LRM12L1X520S10AH ships as a full set: a 520 mm stainless rail, 12 mm wide, with one long recirculating-ball carriage pre-fitted and pre-greased. The S10 code puts the end mounting hole 10 mm from the rail tip, leaving fastener clearance in shallow or crowded frames. Preload grade A leaves the carriage free-rolling, accuracy H is the high grade, and the absence of a trailing T means the rail mounts from the top.
Design points that matter here: the common-rail profile lets other LRM12 carriages share this same rail, the double-lip seal does the oil-scraping and dust-exclusion work, and the outer cover shields both the seal strip and the screw heads. The recirculating balls are Japanese-made and graded ISO 3290 G10 for roundness - that grade applies to the balls alone, not to the guide as a whole. Handling still needs care: despite ball retention, an angled insertion or a hasty carriage swap can drop balls onto the bench. Ambient temperature must stay at or under 80 C, with peaks to 100 C - worth checking near heaters, ovens or laser heads. Since LRM publishes no load or moment ratings, we confirm the figures for this model when you enquire through the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X520S10AH Is Used
Micro-dispenser head
Guiding an adhesive micro-dot dispenser across a 520 mm pass on a small electronics line; preload A keeps running drag low, which suits a head repositioned dot by dot.
Vision camera traverse
Carrying an inspection camera along a 520 mm viewing line on a production tester, with the 10 mm end offset leaving room for the end fixings inside a shallow frame.
Desktop pick-and-place axis
One axis of a compact desktop pick-and-place, where the long carriage gives a steadier footing for a lightweight vacuum head moving between feeders and the board.
Is the Airtac LRM Miniature Linear Guide LRM12L1X520S10AH the Right Guide?
Start the checklist with the figures that are published: rail width 12 mm, rail length 520 mm, one long carriage, preload A, accuracy H, top-mount rail and a 10 mm end offset. Then the figure that is not: LRM carries no published load or moment rating, so confirm it with us for this model before committing. Preload A gives the lowest drag and a free-rolling feel; if the application later needs more rigidity, grade B lightens the play and grade C is the rigid, less forgiving choice - both are stocked in size 12. If the load is substantial or overhangs the carriage, move up to LSH, which publishes per-carriage dynamic, static and moment ratings you can actually size against. For short travel where crossed-roller rigidity matters more than stroke, LGC is the cross-range alternative. Size 12 is the deep end of our stock - 924 of 988 stocked LRM sets - so availability here is the best the series offers.
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 LRM12L1X520S10AH FAQ
Published: 12 mm rail width, 520 mm rail length, one long carriage, preload A (none), accuracy grade H (high), top-mount rail with the first hole 10 mm from the end. Screws: M2 at 58.8 N.cm into steel, 39.2 N.cm into cast iron, 29.4 N.cm into aluminium; M3 at 196, 127 and 98 N.cm respectively. Carriages leave the factory with Kyodo Yushi PS No. 2 grease; top up every 100 km of travel or every 3 to 6 months, in the quantity listed per model. Ambient temperature limit is 80 C with transient peaks to 100 C. Not published: load and moment ratings - we confirm them per model.
Pick LSH when the load is substantial or cantilevered, because LSH publishes per-carriage dynamic, static and moment ratings you can size against; LRM publishes none of these, so with this LRM12L1X520S10AH we confirm the figures for the model before you order. Pick LRM when the priority is a small envelope, smooth light-duty motion and a 12 mm rail in a 520 mm length. For short travel needing crossed-roller rigidity, LGC is the cross-range alternative. Either way, send the application details and we will confirm the rating for the exact model.
