Airtac LRM Miniature Linear Guide LRM12L1X145S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X145S10AP 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 LRM12L1X145S10AP
LRM12L1X145S10AP is the precision-grade version of a compact AirTAC miniature guide set: a single 12 mm wide stainless-steel rail, 145 mm end to end, running one long recirculating-ball carriage. The P in the code selects precision accuracy rather than the high grade, so the guide's geometric tolerances are held to a tighter band than the H equivalent. You receive rail and carriage assembled, greased and ready to mount on a ground or finish-milled surface.
Size 12 is where the LRM range actually lives: 924 of the 988 complete sets in our stock are LRM12, which makes this the best-supported width for both availability and price. The balls inside the carriage are Japanese-made and graded ISO 3290 G10 - a ball grade only, not an assembly standard - while the double-lip seal and outer cover protect the raceways from chips and dust. Keep the surroundings below 80 C ambient, with only brief excursions to 100 C. Because LRM has no published load or moment table, capacity is confirmed per model: send the mass, lever arms and cycle over RFQ and we will come back with the answer for this exact set.

Where the Airtac LRM Miniature Linear Guide LRM12L1X145S10AP Is Used
Wafer probe positioning
A small probe-card slide on a test bench: the precision grade holds the probe line steady over the stroke while the 12 mm rail fits the tight fixture envelope.
Fibre alignment stage
Truing a fibre collimator to a lens axis: grade P tolerances and recirculating balls graded ISO 3290 G10 give the smooth, repeatable motion fine alignment work demands.
Optical bench trim slide
A manual trim axis for tweaking a mirror position on an optical bench: with no preload the slide takes only fingertip force, so the setting is not disturbed.
Is the Airtac LRM Miniature Linear Guide LRM12L1X145S10AP the Right Guide?
A short 145 mm rail keeps this set at the low end of the stocked price span, which runs about $66 to $831 and is driven almost entirely by rail length and carriage count rather than width - trim travel before you widen the rail. If your load is heavy or overhung, LSH is the step up: it publishes per-carriage dynamic, static and moment ratings you can plug into a calculation, something LRM deliberately does not. If the travel is very short and crossed-roller rigidity beats cost, compare LGC. One maintenance note: the 100 km re-grease interval arrives faster than it reads, since a slide cycling a short stroke continuously covers that distance in a few weeks, so calendar top-ups every 3 months are the safer habit on busy machines. Before ordering, settle the checklist: set versus carriage-only, rail width, carriage length, carriage count, rail length, preload (none here - free running, lowest drag, least rigidity), accuracy grade, mounting direction, and a load rating confirmed 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 LRM12L1X145S10AP FAQ
Confirmed details: 12 mm rail width, 145 mm rail length, one long carriage, preload A (none), accuracy grade P (precision), top-mount rail, 10 mm end-hole offset. Installation: mount on a ground or finish-milled face; M3 screw torque is 196 N.cm into steel, 127 N.cm into cast iron and 98 N.cm into aluminium (M2: 58.8, 39.2 and 29.4 N.cm). Environment: 80 C ambient maximum with brief peaks to 100 C. Service: pre-filled with Kyodo Yushi PS No. 2; re-grease every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them per model.
Grade P tightens the geometric tolerances of the guide, but it does not add load capacity - LRM has no published dynamic, static or moment ratings at either grade, and we confirm capacity for the specific model on request. If your sizing calculation needs published per-carriage ratings because the load is heavy or cantilevered, step up to LSH, which provides them. If the travel is very short and you need crossed-roller stiffness, LGC is the alternative. For this precision set itself: 12 mm rail, 145 mm long, one long carriage, top-mount, no preload.
