Airtac LRM Miniature Linear Guide LRM15L1X170S25AH
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X170S25AH is a miniature linear guide on a 15 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 LRM15L1X170S25AH
This AirTAC LRM complete set pairs a 170 mm stainless-steel rail, 15 mm wide, with a single long recirculating-ball carriage. What makes LRM15L1X170S25AH distinctive in the code is the S25 segment: the first fixing hole at each rail end is offset 25 mm from the tip, a wider end spacing than the common 5, 10 or 15 mm options. Check that dimension against your baseplate drilling before you release the drawing, because it changes where your screws land relative to the stroke you actually get. The rail is drilled for top-mount fixing and the carriage arrives fitted, greased and ready to run.
Inside the carriage, ISO 3290 G10 balls (the grade covers the balls only, not the assembly) circulate in a retained path, so they will not scatter during routine handling. The double-lip seal handles oil retention and dust exclusion, and the outer cover protects the seal strip from larger debris while concealing the screw line. Do not mount this set where ambient heat pushes past 80 C - near an oven door or a laser head the 100 C transient peak is the absolute ceiling. Load and moment ratings are not published for LRM; ask us and we will confirm the figures for this exact model before ordering.

Where the Airtac LRM Miniature Linear Guide LRM15L1X170S25AH Is Used
Electronics assembly feed slide
A component feed slide on a small SMT bench machine indexes parts to a pickup point; the 25 mm end offset gives extra fixing purchase at the rail ends where the accel/decel loads land.
Laser diode alignment slide
Aligning a diode module in an optical test fixture calls for fine, smooth adjustment; the unloaded long carriage on a 170 mm rail gives repeatable positioning without stick-slip.
Fibre connector polish fixture
A polish fixture indexing fibre connectors across a lapping film uses a light, precise slide; the long carriage keeps the connector head level through the polishing stroke.
Is the Airtac LRM Miniature Linear Guide LRM15L1X170S25AH the Right Guide?
Start from the mounting hole pattern: the 25 mm end-hole offset on this set must line up with your baseplate, so verify it against the drawing first. Then step up to LSH if the load is heavy or overhung - LSH gives you published dynamic, static and moment ratings per carriage to size against, which LRM simply does not provide. If the travel is short and the priority is crossed-roller rigidity, LGC is the closer match. Checklist for this SKU: complete set (not carriage only), 15 mm rail width, long carriage, one carriage, 170 mm rail, preload A (lightest grade, easiest installation, least rigidity), accuracy H, top-mount, and confirm the load rating with us before you commit.
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 LRM15L1X170S25AH FAQ
Stainless-steel rail 15 mm wide and 170 mm long, one long carriage, preload A (none), accuracy H (high), top-mount rail, end fixing holes offset 25 mm from each rail end. Screw torques: M2 at 58.8 N.cm into steel (39.2 cast iron, 29.4 aluminium); M3 at 196 N.cm into steel (127 cast iron, 98 aluminium). Maximum ambient temperature 80 C, transient peaks 100 C. Ships pre-greased with Kyodo Yushi PS No. 2; re-grease every 100 km or every 3 to 6 months, whichever comes first. Note that load and moment ratings are not published for LRM at all - we confirm them per model through the RFQ.
Choose LRM when the envelope is tight and the duty is light precision positioning - that is what this 15 mm rail and long carriage are built for. Choose LSH when the load is substantial or cantilevered, because LSH publishes basic dynamic, static and moment ratings per carriage that you can put straight into your sizing calculation; LRM has no published ratings, so sizing means confirming figures with us per model. If travel is short and you need crossed-roller rigidity instead, look at LGC. Send the application details and we will confirm the LRM rating or recommend the right series.
