The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X395S10CH 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.
LRM12N1X395S10CH is a complete AirTAC LRM set - one 12 mm wide, 395 mm long stainless-steel rail with a single standard-length recirculating-ball carriage fitted, so nothing else is needed to mount and run it. The C preload grade is the medium option on LRM: it tightens the internal clearances for a firmer-feeling slide, at the cost of a little extra running drag.
Outer covers conceal the fixing screws and shield the double-lip seal strip from larger debris, which suits a bench near chips, fibres or spilled granules. The balls are ISO 3290 G10 Japanese grade, retained in the carriage so they stay put during careful handling. Ambient temperature must not exceed 80 C, peaking at 100 C - worth remembering beside a heater or inside a warm enclosure. LRM publishes no load or moment ratings, so we confirm them for this exact model on request; send the RFQ and we will reply with the figures.

Rail and carriage(s) supplied together, matched as a set. If you are not sure which form you need, send us the machine or the original part number and we will confirm it before you order.
A light press-fit fixture in a small-parts cell uses the medium preload for a firmer, less forgiving slide that resists drift under repeated positioning.
A labelling head tracks a narrow web on a 12 mm rail; the 395 mm stroke covers a full label pitch while the sealed carriage shrugs off paper dust.
A tensile-test jig aligns slender specimens before a pull; the single standard carriage lets an operator nudge the clamp into line with predictable, damped movement.
Preload C trades free running for rigidity, so pick it when a stage must not drift, and choose B instead when a light, easy slide matters more. If the load is genuinely substantial or cantilevered, LSH publishes per-carriage dynamic, static and moment ratings you can size against, which LRM does not; for short travels wanting crossed-roller stiffness, look at LGC. Checklist for this SKU: complete set with rail included, 12 mm rail width, standard carriage length, one carriage, 395 mm rail, medium preload C, accuracy H high, top-mount fixing. Install on a ground or finish-milled surface and confirm the load rating with us before committing - the RFQ covers it.
Quick checklist
A 12 mm wide stainless-steel rail of 395 mm with a single standard carriage, medium preload C, high accuracy H and top-mount rail fixing. Install on a ground or finish-milled surface, and torque M3 screws to 196 N.cm into steel, 127 N.cm into cast iron or 98 N.cm into aluminium; M2 screws take 58.8, 39.2 or 29.4 N.cm. Ambient temperature must stay at or below 80 C, peaking at 100 C, and re-greasing is due every 100 km of travel or every 3 to 6 months. Load and moment ratings are not published; we confirm them for this model before ordering.
LRM12N1X395S10CH is a complete set - rail and fitted carriage, pre-filled with Kyodo Yushi PS No. 2 grease - so no pairing code applies. Carriage-only codes end in BK and carry a pairing letter A to E that must match the rail, so a replacement carriage needs the letter taken off the original part. We hold very few carriage-only SKUs, so most spares are special orders - one more reason to handle this set's carriage carefully and keep it on the rail.
