Airtac LRM Miniature Linear Guide LRM12L2X170S10CPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L2X170S10CPT 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 LRM12L2X170S10CPT
The LRM12L2X170S10CPT combines the two ends of LRM's precision story: grade P accuracy and bottom-mount fixing on one 12 mm, 170 mm stainless-steel rail with two long carriages. The T suffix moves the clamping holes to the underside, so the rail bolts up under a plate or inside a channel where the top face stays unobstructed - a layout common in semiconductor test heads and optical benches.
Long carriages spread the load across more balls and stretch the bearing span, while the twin-block layout resists pitch along the 170 mm of travel; medium preload removes play where repeatability counts, though it demands well-finished seats. The recirculating balls are Japanese-made ISO 3290 G10 - that grade covers the balls only, not the assembly - behind double-lip seals under a screw-hiding outer cover. Ambient temperature must stay at or below 80 C, briefly to 100 C. LRM carries no published load or moment ratings; we confirm the figures for this exact model through the RFQ before you order.

Where the Airtac LRM Miniature Linear Guide LRM12L2X170S10CPT Is Used
Probe-card indexer
A die-level test bench indexing a socketed device between probe contacts uses bottom-mount fixing to tuck the rail beneath the chuck plate; precision grade P keeps the contact pattern registered stroke after stroke.
Lab dosing module
A fluid-dosing slide for laboratory diagnostics needs smooth, well-sealed motion; the double-lip seals retain grease and exclude splashes, though the assembly itself carries no published ingress rating - confirm suitability with us.
Laser marker focus axis
A compact laser marker's focus axis makes fast, short Z strokes over the workpiece; because the head sits near a warm source, respect the 80 C ambient ceiling, and precision accuracy holds the focal plane position.
Is the Airtac LRM Miniature Linear Guide LRM12L2X170S10CPT the Right Guide?
Step up to LSH as soon as the load becomes substantial or hangs off a cantilever: LSH tables give dynamic, static and moment figures per carriage to calculate with, whereas LRM's ratings are unpublished and confirmed per model. Step across to LGC when the travel is short and crossed-roller rigidity matters more than stroke. For this SKU confirm the form (complete set), 12 mm rail width, long carriage, two blocks on a 170 mm rail, medium preload with its stiffness-versus-forgiveness trade-off, precision grade P and the bottom-mount hole pattern; a spare block ordered separately must carry a matching pairing letter. Send the RFQ so we confirm the rating - and note that size 12 makes up 924 of the 988 LRM sets we hold, so this one ships fastest.
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 LRM12L2X170S10CPT FAQ
Take the LRM12L2X170S10CPT when space is tight and duty is light: 12 mm rail, 170 mm long, two long carriages, precision accuracy, bottom-mount fixing. Take LSH when loads or cantilevers get serious - its catalogue publishes dynamic, static and moment ratings per carriage, which is exactly what LRM lacks, so we confirm LRM load figures per model instead. LGC covers short-travel work where crossed-roller rigidity is the priority.
Published: rail width 12 mm, rail length 170 mm, two long carriages, preload C (medium), accuracy P, bottom-mount (T) fixing, an 80 C ambient limit with 100 C peaks, re-grease every 100 km or 3 to 6 months, and catalogue screw torques (M2: 58.8 N.cm into steel, M3: 196 N.cm). Not published: load, moment and speed ratings - those are confirmed per model, so send the RFQ and we will size it with you.
