Airtac LRM Miniature Linear Guide LRM15L1X190S15CP
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X190S15CP 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 LRM15L1X190S15CP
LRM15L1X190S15CP is a complete miniature linear guide: one 15 mm wide stainless rail, 190 mm long, carrying a single long ball carriage with medium preload and precision accuracy grade P, top-mounted. In this configuration the P grade tightens the travel tolerance while preload C holds the carriage firmly against the raceways, and the set is delivered assembled, ready to screw down from above.
The firm pairing suits work where both repeatability and absence of play matter - though the tighter grade and preload raise running drag slightly and demand a properly prepared, ground or finish-milled seat. Ball-retention construction keeps the ISO 3290 G10 Japanese balls - a grade for the balls themselves, not the assembly - from spilling during routine handling, backed by a double-lip seal and an outer cover over the screw line. The published ambient limit is 80 C, transients to 100 C. Load capacity is confirmed per model: send the RFQ and we will return the figure for this exact code.

Where the Airtac LRM Miniature Linear Guide LRM15L1X190S15CP Is Used
Laser marking stage axis
One axis of a compact laser-marking table, where repeatability between marks matters, gains from the P accuracy grade and play-free medium preload over a 190 mm stroke.
Gauge block comparison slide
A metrology lab comparing gauge blocks under a comparator moves the anvil on a short, true path; precision P travel keeps measurement drift low between settings.
Small parts feeder escapement
Indexing tiny parts into a test nest with light linear motion, the long carriage resists rocking and preload C removes play at every stop position.
Is the Airtac LRM Miniature Linear Guide LRM15L1X190S15CP the Right Guide?
When loads become substantial or overhang the carriage, step up to LSH, whose catalogue lists per-carriage dynamic, static and moment ratings that LRM does not publish at all. For short strokes where crossed-roller rigidity is the priority, compare LGC. This item is a complete set: 15 mm rail width, long carriage, one carriage, 190 mm rail, medium preload C, precision P accuracy, top-mount. If you are trimming cost, remember that rail length - not the 15 mm width - drives the price across the stocked 40-995 mm span, so cut travel before you cut size, then confirm the load rating with us.
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 LRM15L1X190S15CP FAQ
Yes - LRM15L1X190S15CP arrives as an assembled guide: a 15 mm stainless rail, 190 mm long, with one long carriage already on it, preloaded C and finished to P accuracy. It is a mechanical guide, not a pneumatic part, so there is no bore, air or pressure involved. Against LSH: choose LSH when load ratings must drive the design, because LSH publishes dynamic, static and moment figures per carriage; LRM's ratings are confirmed only per model through us. For light, compact, precise travel in a tight space, this LRM15 set is the smaller, more economical choice - just verify the load with our RFQ first.
Rail width 15 mm; rail length 190 mm; single long carriage; preload C (medium); accuracy P (precision); top-mount rail; 15 mm end-hole offset. Installation torque: M2 screws 58.8 N.cm (steel), 39.2 (cast iron), 29.4 (aluminium); M3 screws 196, 127 and 98 N.cm. Ambient limit 80 C, brief peaks 100 C; re-grease every 100 km or every 3-6 months with Kyodo Yushi PS No. 2. Load, moment and speed ratings are not published for LRM - we confirm the load rating for this model before you order.
