Airtac LRM Miniature Linear Guide LRM15L1X190S15AP
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X190S15AP 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 LRM15L1X190S15AP
LRM15L1X190S15AP is the precision-grade build of this 15 mm LRM layout: a 190 mm stainless-steel rail, 15 mm wide, carrying one long carriage, end holes offset 15 mm, mounted from the top and supplied with no preload. The P in the code marks accuracy grade P - the tighter of the two grades LRM offers - aimed at work where straightness of travel is the deliverable, such as measurement and inspection duties.
Without preload, the carriage runs at its freest, which suits a hand-moved or lightly driven axis, but it is the least rigid choice if a tipping component leans on it - grade C preload is the stiffer alternative in this series. The long carriage spreads contact across more balls, which helps that stability question. Full-length size 15 rails run to 990 mm in the catalogue, so this 190 mm rail is a trimmed cut, and trimming travel rather than width is what keeps cost down in this range. Balls are Japanese ISO 3290 G10 grade - a ball-grade callout, not a guide standard - behind double-lip seals under an outer cover. Ambient ceiling is 80 C with 100 C transient peaks. Load and moment figures are confirmed per model: raise an RFQ and we will return them for this code.

Where the Airtac LRM Miniature Linear Guide LRM15L1X190S15AP Is Used
Comparator stand build
Building a custom comparator stand where the indicator must track true over 190 mm. Accuracy grade P on a ground or finish-milled seat is the reason this grade exists, and the load rating is confirmed with us per model first.
Measuring microscope refurbishment
Swapping a worn carriage on an older measuring microscope. Only four carriage-only LRM SKUs are stocked, so a replacement is usually a special order - and its pairing code must match the original rail.
Laser cutter shield door
The sliding viewing shield on a small laser cutter. A miniature rail keeps the door light and smooth, the 80 C ambient ceiling sits above typical panel warmth near the cutting zone, and no preload suits a door moved by hand.
Is the Airtac LRM Miniature Linear Guide LRM15L1X190S15AP the Right Guide?
Compare series before comparing codes. LSH answers when the load is real or overhung, because its published per-carriage dynamic, static and moment ratings let you calculate margins - a document LRM simply does not have. LGC answers when the travel is short and crossed-roller rigidity outweighs everything else. For this precision-grade set, run the checklist: complete set, 15 mm rail, long carriage, one block, 190 mm rail, preload A (none) - freest running, lowest rigidity, easiest fitting - accuracy grade P, top-mount fixing, and a load rating confirmed with us per model. If a spare carriage ever enters the picture, note its pairing code from the original. Send the RFQ with your stroke and mounting details and we will close the loop.
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 LRM15L1X190S15AP FAQ
A 15 mm wide, 190 mm long stainless rail with one long carriage, 15 mm end-hole offset, preload A (none), accuracy grade P and top-mount rail fixing. M3 mounting screws torque to 196 N.cm in steel, 127 N.cm in cast iron and 98 N.cm in aluminium. Ambient temperature is capped at 80 C with 100 C transient peaks allowed, and lubrication is refreshed every 100 km of travel or every 3 to 6 months. No load or moment rating is published for LRM - we confirm the figures for this specific model on request.
This set wins when the envelope is tight, the load is light and travel straightness at precision grade matters - a miniature stainless axis that drops into compact fixtures. It loses when the load grows or cantilevers: LSH publishes dynamic, static and moment ratings per carriage for exactly those calculations, and LRM publishes none, so there is nothing to size against. Short travels demanding crossed-roller stiffness belong on LGC instead. If you stay with this code, confirm the load rating with us via RFQ - it is checked per model before ordering.
