Airtac LRM Miniature Linear Guide LRM12L1X370S10CH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X370S10CH 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 LRM12L1X370S10CH
LRM12L1X370S10CH is a complete miniature guide set: a 370 mm long, 12 mm wide stainless-steel rail with one long recirculating-ball carriage, high accuracy grade H, a top-mounted rail and a 10 mm end-hole offset. The C in the preload position is the medium grade - the stiffest offered anywhere on LRM.
Medium preload buys running rigidity and pays for it in fit: the carriage slides onto the rail with more resistance, so clean, correctly torqued mounting surfaces matter more - M3 screws at 196 N.cm into steel, 127 into cast iron, 98 into aluminium. Inside, the carriage runs on Japanese ISO 3290 G10 balls, a grade that applies to the balls only and not to the assembly, behind a double-lip seal and an outer cover, with an 80 C ambient ceiling. One practical note: the 100 km re-grease interval arrives faster than it reads - a 200 mm stroke cycling once per second covers it in roughly three weeks of continuous running, so distance binds before the calendar does. Load ratings are not published for LRM; we confirm them for this model when you enquire.

Where the Airtac LRM Miniature Linear Guide LRM12L1X370S10CH Is Used
Micro-conveyor shuttle positioning
A product shuttle on a lab-scale conveyor line, where medium preload keeps the carrier from rocking as it stops and starts along the 370 mm rail.
Lens focus axis on a vision system
Moving a camera lens along its optical axis; the stiff, preloaded long carriage removes the play that would blur focus at every stop position.
Probe carriage on a test bench
A spring-probe fixture carried across test points; the long bearing span resists the tipping a probe arm applies off to one side of the carriage.
Is the Airtac LRM Miniature Linear Guide LRM12L1X370S10CH the Right Guide?
This code suits a light axis that must not wobble: the medium preload and the long carriage both push against rocking. If your load is genuinely heavy or sits on a cantilever, move to LSH - its per-carriage dynamic, static and moment ratings let you size properly on paper, something the LRM catalogue does not provide, so we verify LRM capacity model by model. Short travel demanding crossed-roller rigidity points to LGC instead. Checklist: set with rail included, 12 mm width, long carriage, one block, 370 mm rail, preload C (rigid but less forgiving of misalignment), H accuracy, top-mount, and a load figure confirmed with us before ordering.
Quick checklist

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 LRM12L1X370S10CH FAQ
Rail width 12 mm, rail length 370 mm, long-type carriage, count 1, preload C (medium), accuracy H (high), top-mount rail, 10 mm end offset. Mounting torque for M3 screws: 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium. Ambient limit 80 C with transient peaks to 100 C. Grease interval: every 100 km of travel or every 3 to 6 months. Basic dynamic and static load ratings, moment ratings and speed limits are not published for LRM - the figure for this exact model is confirmed by us on enquiry.
One stainless-steel rail, 370 mm long, drilled for top-mounting with holes 10 mm in from each end, plus one long carriage pre-greased with Kyodo Yushi PS No. 2 and matched to that rail. Nothing else is needed to run it; wipe off the rust-preventive oil and lubricate before first use. A spare carriage is a separate BK-ordered part, and most carriage-only codes are special-ordered rather than carried.
