Airtac LRM Miniature Linear Guide LRM15L1X190S15CH
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X190S15CH 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 LRM15L1X190S15CH
LRM15L1X190S15CH is a complete AirTAC LRM miniature linear guide in the size 15 series: one stainless-steel rail 15 mm wide and 190 mm long, carrying a single long recirculating-ball carriage. The C suffix is the medium preload grade - the firmest option offered on LRM - so the carriage runs with minimal internal play at the cost of slightly higher sliding resistance than a grade A or B block. The set arrives assembled, greased with Kyodo Yushi PS No. 2 and ready for top-mount fixing.
Underneath, the construction is LRM standard: a common rail profile shared by all carriages in the series, ball retention that keeps the Japanese-made ISO 3290 G10 balls (a ball-only grade) from spilling during handling, a double-lip seal, and an outer cover that conceals the screws and keeps larger debris off the seal strip. Two practical points for a C-preload block: the stiffer feel earns its place only where play genuinely hurts, and the re-grease clock runs at 100 km of travel or 3 to 6 months, whichever comes first - a 190 mm stroke cycling once per second covers that distance in under a month of continuous running, so distance binds before the calendar does. No dynamic, static or moment figure is published for LRM; we confirm the rating for this exact model when you enquire.

Where the Airtac LRM Miniature Linear Guide LRM15L1X190S15CH Is Used
Semiconductor test socket indexer
A fixture that steps a small device carrier between test sockets benefits from the C-preload block holding position without drift between steps.
Digital microscope stage translation
A 190 mm axis under a benchtop digital microscope moves slides and small boards smoothly past the objective; grade H keeps the image steady across the travel.
Compact adhesive dispensing gantry
A light dispensing head traverses a short axis over a PCB; the long carriage keeps the head square when the nozzle overhangs the mounting face.
Is the Airtac LRM Miniature Linear Guide LRM15L1X190S15CH the Right Guide?
Preload C is the rigid, less forgiving choice: it removes most of the internal play but asks for clean, well-aligned mounting surfaces - ground or finish-milled - to run at its best. If your load is heavy or cantilevered, do not try to solve it with preload; step up to LSH, which publishes per-carriage dynamic, static and moment ratings you can size against, or cross-check LGC where travel is short and crossed-roller rigidity is the priority. Before ordering, tick off: complete-set form, 15 mm rail width, long carriage, one block per 190 mm rail, preload C, accuracy H, top-mount direction, and a load rating confirmed with us. Worth knowing: long carriages are held as deeply as standard ones across this range, and a set's price is driven mainly by rail length and carriage count, not by the 15 mm width.
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 LRM15L1X190S15CH FAQ
Published for LRM15L1X190S15CH: 15 mm rail width, 190 mm rail length, a single long carriage, medium preload (grade C), high accuracy (grade H), top-mount rail. Screw torque is 196 N.cm into steel, 127 into cast iron and 98 into aluminium for M3 screws (58.8, 39.2 and 29.4 N.cm for M2). Ambient temperature must not exceed 80 C, peaking briefly at 100 C, and re-greasing falls due every 100 km or 3 to 6 months. Deliberately absent: dynamic, static and moment load ratings, which AirTAC does not publish for LRM - we verify them per model before your order is confirmed.
The complete set: one 190 mm stainless rail and one long carriage fitted to it, pre-greased. There is no second carriage, no mounting screws and no mating plate in the box. If you later need a spare carriage, remember that LRM carriage-only items are ordered separately under their own pairing code, and only a handful of those are held - most spare blocks are a special order, so it pays to note the pairing letter of your rail when you first buy.
