Airtac LRM Miniature Linear Guide LRM12N1X495S10APT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X495S10APT is a miniature linear guide on a 12 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 LRM12N1X495S10APT
Order code LRM12N1X495S10APT breaks down as a 12 mm stainless rail 495 mm long with one standard recirculating-ball carriage, and the trailing T changes the mounting story: fixing holes are taken from underneath, so a table can be drilled and bolted from below while the top face stays uninterrupted.
Because the screws sit underneath, surface preparation matters even more - the seat should be ground or finish-milled for the P grade to deliver its tighter travel accuracy. The double-lip seal and outer cover protect the raceway and seal strip in a machining environment, and the ball-retainer design keeps the balls with the carriage during handling. Balls are ISO 3290 G10 Japanese steel, a ball-only grade. Keep the ambient at or under 80 C (100 C transient). We hold no published load or moment figures for LRM; ask us and we confirm them per model before you order.

Where the Airtac LRM Miniature Linear Guide LRM12N1X495S10APT Is Used
IC tray-to-tube handler
A pick head moving QFP devices from JEDEC tray to output tube; the bottom-mount rail sits in a milled pocket, leaving no screw heads for the gripper to foul.
Laser diode focus carriage
A miniature optics bench racks a collimating lens along 495 mm while a power meter logs the sweet spot; P accuracy holds the setting between runs.
Cable-flex test sled
A lab rig drags a sample harness back and forth over a mandrel; the 12 mm stainless rail shrugs off the light side pull of the cable loop.
Is the Airtac LRM Miniature Linear Guide LRM12N1X495S10APT the Right Guide?
Before you order, check the seating: LRM travel accuracy is only as good as the mounting face, which should be ground or finish-milled, and either rail edge can serve as the datum. This P-grade, bottom-mount set suits a table machined and bolted from underneath. Sizing caution: when the load is heavy or cantilevered, LSH is the better series because it publishes per-carriage dynamic, static and moment ratings - LRM does not, and we confirm each LRM figure individually. For short travel where crossed rollers give the stiffness, LGC fits. Checklist: set form, 12 mm rail, standard carriage, count 1, 495 mm length, preload A, accuracy P, bottom-mount direction. Send the RFQ and we will confirm the load rating for this exact SKU.
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 LRM12N1X495S10APT FAQ
A 12 mm wide stainless rail 495 mm long, 10 mm hole offset, one standard carriage, preload A (none), P precision accuracy, bottom-mount hole pattern. Screw torque in steel is 58.8 N.cm for M2 and 196 N.cm for M3; in cast iron 39.2 and 127; in aluminium 29.4 and 98. Keep ambient temperature at or under 80 C with no sustained peaks above 100 C. Grease interval: 100 km of travel or 3 to 6 months, whichever comes first. The manufacturer publishes no load or moment ratings for LRM, so we confirm those figures for this SKU when you enquire.
This is a complete set: one bottom-mount 12 mm rail cut to 495 mm plus one standard recirculating-ball carriage, factory-filled with Kyodo Yushi PS No. 2. The ball-retention design helps during handling, but fitting the carriage at an angle or rushing a removal can still drop balls, so a dummy rail is worth planning for. Carriages ordered alone use the LRM12BK- code shape with a pairing letter that must match the rail; we stock only four carriage-only SKUs, so most replacement carriages are a special order.
