Airtac LRM Miniature Linear Guide LRM12L2X170S10AP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X170S10AP is a miniature linear guide on a 12 mm stainless-steel rail with recirculating-ball carriages. 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 LRM12L2X170S10AP
LRM12L2X170S10AP is the precision-grade version of this set: one 12 mm wide stainless-steel rail, cut to 170 mm, carrying two long (L) ball carriages, top-mounted, with no preload (grade A). Accuracy grade P sits above H with tighter dimensional and running tolerances, so the useful trade here is buying parallelism between paired rails when a two-rail stage must stay flat along the stroke.
Inside the carriages, the recirculating balls are Japanese-made to ISO 3290 G10 - that grade applies to the balls alone, not to the guide assembly. The double-lip seal does the oil-scraping and dust-exclusion work while the outer cover hides the screw heads and keeps larger debris off the seal strip. Carriages arrive pre-filled with Kyodo Yushi PS No. 2; re-grease every 100 km of travel or every 3 to 6 months, and never mix lubricant types. Keep ambient temperature under 80 C (transient peaks to 100 C). Load and moment figures are confirmed per model rather than published - send the RFQ and we will verify them for this code.

Where the Airtac LRM Miniature Linear Guide LRM12L2X170S10AP Is Used
PCB inspection camera rail
An AOI camera slide over a printed circuit board: precision grade P keeps the rail-to-rail parallelism of a twin-rail stage tight, so focus stays consistent along the 170 mm scan.
Optical bench translator
A small translator moving a photodiode or sample holder across a laser path on an optical table: no preload (grade A) means low, even drag for fine positioning by hand or micrometer drive.
Semiconductor jig micro-stage
A wafer-handling micro-stage inside a tight fixture envelope: the 12 mm rail width and stainless rail suit cleanroom jigs, provided ambient temperature stays at or below 80 C.
Is the Airtac LRM Miniature Linear Guide LRM12L2X170S10AP the Right Guide?
Run through the spec list: set form, 12 mm rail, long carriages, two per rail, 170 mm length, preload A (none - simple fitting, though with no preload you accept a little play), precision accuracy P, top-mount. Send the RFQ so we can confirm the load rating for this specific model - LRM has no published figures. If your load is significant or cantilevered, move up to LSH, which publishes per-carriage dynamic, static and moment ratings that LRM does not. If the stroke is short and crossed-roller rigidity matters more, LGC fits. Price note: across the two stocked rail widths, sets run from roughly $66 to $831, and nearly all of that spread is rail length - trimming travel beats resizing.
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 LRM12L2X170S10AP FAQ
A 12 mm wide stainless-steel rail, 170 mm in length, top-mount fixing, two long carriages, no preload (A) and precision accuracy P. Screw torques: M2 - 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 - 196, 127 and 98 N.cm in the same order. Ambient temperature ceiling is 80 C, transient peaks 100 C. Grease interval: 100 km of travel or 3 to 6 months, whichever comes first. LRM carries no published load or moment ratings, so we confirm the figures for this exact model - send the RFQ.
Step up when the load or the overturning moment grows beyond what a miniature guide can be comfortably trusted with. LSH publishes dynamic, static and moment ratings per carriage in its catalogue, so you can run the numbers yourself; LRM publishes none, which is why we confirm the rating for your specific model before ordering. Stay with this LRM12 set when the envelope is tight, the duty is light and positioning smoothness is the priority, and consider LGC when the stroke is short and crossed-roller rigidity is what the application needs.
