Airtac LRM Miniature Linear Guide LRM12L1X445S10CH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X445S10CH 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 LRM12L1X445S10CH
This LRM12L1X445S10CH set is the stiffest-feeling option in the stocked size-12 long-carriage family: a 445 mm stainless-steel rail, 12 mm wide, with one long recirculating-ball carriage set to preload grade C, the medium grade and the highest offered on LRM. Accuracy is grade H (high), and the rail fixes from above. What arrives is the assembled rail and carriage, ready to bolt to a prepared surface.
Preload C removes most of the internal play, which tightens up reversing motion and any tipping tendency of a vertically loaded head - but it is the less forgiving choice: it runs with more drag, and it rewards a properly prepared seat. AirTAC specifies ground or finish-milled mounting surfaces, and either edge of the rail can be taken as the datum. The long carriage lengthens the bearing span and spreads load across more balls, complementing the firm preload. Sealing is a double-lip design under an outer cover that hides the screws and keeps larger debris away; the balls are Japanese-made to ISO 3290 G10, a grade for the balls themselves only. Keep the ambient at or below 80 C, peaks to 100 C. Availability is strong here: size 12 accounts for 924 of the 988 LRM sets we stock, and long carriages are held as deeply as standard ones. Load and moment ratings are not published for LRM, so we confirm them for this model through your RFQ before you commit.

Where the Airtac LRM Miniature Linear Guide LRM12L1X445S10CH Is Used
Compact pick-and-place head
A vacuum head moving vertically over a 445 mm rail benefits from the long carriage span and medium preload resisting the tipping component on each reversal.
Small-parts sorting slider
The sort finger shuttles parts between lanes with minimal play under direction changes, thanks to grade C preload on the 12 mm rail.
Bench-top marking and engraving head
A stylus head traverses workpieces along the 445 mm travel; the firm preload keeps the tool position steady as it lifts between marks.
Is the Airtac LRM Miniature Linear Guide LRM12L1X445S10CH the Right Guide?
Pick preload C when your motion reverses often and you want the internal play squeezed out - accept the higher running drag and the demand for a clean, ground or finish-milled seat. If the load turns out to be substantial or cantilevered, the honest next step is the LSH series, which publishes dynamic, static and moment ratings per carriage; LRM lists none of these, which is why we confirm ratings model by model. For short strokes needing crossed-roller rigidity, LGC is the alternative to weigh. Checklist for this SKU: complete-set form, 12 mm rail width, long carriage, one carriage on a 445 mm rail, preload C medium (stiffest, least forgiving), accuracy H high, top-mount direction. If the plan includes buying a spare carriage later, its pairing code must match - and since our carriage-only stock is minimal, plan that as a special order. Send load, moment and stroke data with the RFQ and we will confirm this model suits.
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 LRM12L1X445S10CH FAQ
Preload C is the medium grade, the highest offered on LRM: it removes most internal play for a firmer, stiffer feel, at the cost of more running drag and a demand for properly prepared mounting surfaces (ground or finish milled). The set itself: 12 mm wide stainless-steel rail, 445 mm long, one long carriage, top-mount, accuracy grade H. Screw torques from the catalogue run 58.8 N.cm (M2, steel) down to 29.4 N.cm (M2, aluminium) and 196 N.cm (M3, steel) down to 98 N.cm (M3, aluminium). Ambient limit 80 C, transient peaks 100 C; re-grease every 100 km or 3 to 6 months. Load and moment ratings are not published for LRM - we confirm them per model through your RFQ.
Yes - LRM12L1X445S10CH is a complete set: rail plus carriage, assembled and pre-filled with Kyodo Yushi PS No. 2 grease. Before first use, wipe off the rust-preventive oil and apply fresh lubricant; never mix lubricant types. To top up, stroke the carriage back and forth, inject grease through the lubrication hole at the rear of the carriage, and confirm an even film on the rail. The interval is every 100 km of travel or every 3 to 6 months, whichever comes first - on a short, fast stroke the distance can arrive well before the calendar. Do not dismantle the carriage or separate it from the rail unless necessary, and store any spare flat, oiled and sealed away from heat and humidity.
