Airtac LRM Miniature Linear Guide LRM15L1X115S17.5AH
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X115S17.5AH 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 LRM15L1X115S17.5AH
LRM15L1X115S17.5AH is a complete set: a 15 mm wide stainless rail, 115 mm long, carrying a single long recirculating-ball carriage with no preload (A) and high accuracy (H), fixed from the top. The distinctive segment is S17.5 - the end mounting holes sit 17.5 mm in from each rail end instead of the 15 mm offset used elsewhere in the range, shifting where your end screws land relative to the carriage travel.
That offset matters most when you are matching an existing tapped plate: if the holes are already drilled at 17.5 mm, this is the code that lines up without re-machining. The ball-retention design keeps the carriage's balls in place during handling, the balls themselves are Japanese-made to ISO 3290 G10, and the outer cover hides the screw heads while shielding the double-lip seal from debris. Ambient temperature must stay at or below 80 C, briefly to 100 C. As with every LRM model, load and moment ratings are not published - we confirm them per model, so include your duty on the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM15L1X115S17.5AH Is Used
Retrofit onto an existing drilled plate
When a machine plate is already tapped 17.5 mm from each end, this offset code bolts straight on without re-drilling the fixture.
High-cycle vision sorting table
A short-stroke table indexing thousands of times a shift under a vision camera benefits from the free-running carriage - and remember the 100 km re-grease interval arrives faster than the calendar on duty like that.
Small-parts feeder slide
A compact feeder that nudges components onto a belt uses the 115 mm rail as a low-friction guide for its pusher arm, with no preload to fight on each stroke.
Is the Airtac LRM Miniature Linear Guide LRM15L1X115S17.5AH the Right Guide?
Start from the hole pattern: if your plate is already drilled for a 17.5 mm end offset, this set saves re-machining that no other code in the range matches. When the load outgrows light duty or hangs off a cantilever, LSH is the right step - it publishes dynamic, static and moment ratings per carriage, which LRM never does; short-travel work needing crossed-roller rigidity belongs on LGC. Confirm the full checklist: complete set, 15 mm width, long carriage, single block, 115 mm rail, preload A, high accuracy, top-mount direction, and the load rating confirmed with us. Stocked rail lengths run 40-995 mm, so non-standard cuts like this are usually straightforward.
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 LRM15L1X115S17.5AH FAQ
A 15 mm wide stainless rail of 115 mm, one long carriage with no preload, high accuracy (H) and top-mount fixing, with end mounting holes 17.5 mm in from each rail end. Use M3 screws torqued to 196 N.cm in steel, 127 in cast iron and 98 in aluminium. Keep the ambient at or below 80 C (brief peaks to 100 C) and re-grease every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them per model before ordering.
You receive the complete matched set: the 115 mm rail with its long carriage already fitted and pre-filled with Kyodo Yushi PS No. 2 grease. Mounting screws are not included. Before first use, wipe off the rust-preventive oil and apply lubricant, and never mix lubricants of different types. Size 15 sets like this one are stocked, though size 12 remains the deep end of our range; carriage-only replacements are a special order, so if a spare carriage might be needed later, say so on the RFQ.
