Airtac LRM Miniature Linear Guide LRM15L1X200S20AH
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X200S20AH 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 LRM15L1X200S20AH
The LRM15L1X200S20AH is a complete miniature guide: one 200 mm stainless-steel rail, 15 mm across, carrying a single long recirculating-ball carriage and fixed from above. The S20 segment sets the end-hole offset at 20 mm, so the first and last mounting holes sit 20 mm in from the rail ends - a different drilling pattern from the otherwise identical S14 version, so check it against your frame before ordering. Preload is grade A (none), accuracy grade H (high).
The longest catalogue rail for size 15 is 990 mm, and our stock spans 102 different rail lengths from 40 to 995 mm, which makes a 200 mm set like this a shelf item rather than a special cut. Inside the carriage, Japanese-made balls graded ISO 3290 G10 recirculate along the common LRM rail profile, behind a double-lip seal and an outer cover that hides the screw line and protects the seal strip. Ambient temperature must stay at or below 80 C, with only brief excursions to 100 C. Since no load or moment rating is published for the LRM range, describe the duty in your RFQ and we will confirm the figures for this exact model.

Where the Airtac LRM Miniature Linear Guide LRM15L1X200S20AH Is Used
Electronics assembly gantry
Carrying a small vacuum pick head between feeders on an electronics bench, with the 20 mm end offset letting the rail bolt flush to pre-drilled frame rails.
Measuring-slide alignment
A high-accuracy single-axis slide for squaring a dial indicator or vision system against a workpiece in a small quality-control cell.
Vial capping press guide
Guiding a light press head that seats caps onto vials at a packaging bench, its long body resisting the tipping a short block would see at full extension.
Is the Airtac LRM Miniature Linear Guide LRM15L1X200S20AH the Right Guide?
If the duty involves meaningful loads or an overhung mass, choose LSH instead - it prints per-carriage dynamic, static and moment ratings that LRM simply does not publish, so sizing becomes arithmetic rather than a conversation with us. If travel is short and you need crossed-roller stiffness, look at LGC. Before ordering this set, tick off: complete-set form, 15 mm rail width, long carriage, one block, 200 mm rail with a 20 mm end-hole offset (the S14 version shares everything else), preload A, accuracy H, top-mount fixing - and confirm the load rating with us for this model. Bear in mind size 15 makes up only 63 of the 988 sets we stock, so plan ahead if your frame is fixed on 15 mm.
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 LRM15L1X200S20AH FAQ
Published data covers a 15 mm wide, 200 mm long stainless rail with one long carriage, preload A, high accuracy H, top-mount fixing and mounting holes 20 mm from each end. M2 screws torque to 58.8 N.cm into steel (39.2 cast iron, 29.4 aluminium); M3 screws to 196, 127 and 98 N.cm. Running ambient must stay at or below 80 C. The carriage leaves the factory greased with Kyodo Yushi PS No. 2, refreshed every 100 km of travel or every 3 to 6 months. LRM load and moment ratings are not published; we confirm them for this model via the RFQ.
LSH is the larger series and publishes dynamic, static and moment ratings per carriage, letting you verify capacity on paper; LRM publishes none, which is why we confirm the numbers for you model by model. This LRM set wins where a 15 mm rail, a low long carriage and a 200 mm stroke fit a tight envelope, while LGC remains the pick for short strokes that need crossed-roller rigidity.
