Airtac LRM Miniature Linear Guide LRM12L1X445S10BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X445S10BP 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 LRM12L1X445S10BP
This LRM12L1X445S10BP is a matched miniature guide set built for measurement work: a 12 mm wide stainless-steel rail, 445 mm long, topped by a single long recirculating-ball carriage. Accuracy grade P (precision) is one grade finer than the standard high grade, and preload B keeps running drag low. The rail fixes from above; the box contains rail and carriage assembled and ready to bolt down.
The precision grade matters most when the mounting surface is prepared properly - AirTAC specifies ground or finish-milled surfaces to achieve the rated travel accuracy, and either side of the rail can serve as the datum face. The long carriage spreads load over more balls and lengthens the bearing span, a real advantage for a vertically loaded probe or sensor head. The balls inside are Japanese-made to ISO 3290 G10 - that grade covers the balls only - and a double-lip seal plus outer cover protect the raceways from swarf and dust. Expect an ambient limit of 80 C with 100 C transient peaks. One budget note: across the stocked LRM12 range the price spread is driven almost entirely by rail length and carriage count rather than size, so this 445 mm rail sits well above the shortest stocked sets. Load and moment ratings are not published for LRM; we confirm the exact figures for this model through your RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12L1X445S10BP Is Used
Connector-pin measuring fixture
A precision-grade 12 mm rail carries a height gauge carriage along electronics connector rows, where grade P supports repeatable probe positioning.
Laboratory microscope stage retrofit
A light-preload long carriage moves sample trays smoothly under the objective, with the 80 C ambient limit comfortably above lamp-heated stage conditions.
Precision glue-dispensing head
The dispensing needle rides the 445 mm rail across PCB batches; the long carriage stabilises the vertically mounted head against tipping along the travel.
Is the Airtac LRM Miniature Linear Guide LRM12L1X445S10BP the Right Guide?
Before locking in this precision-grade set, check what you actually need to size against. When the load is heavy or overhung, the LSH series is the better tool because it publishes dynamic, static and moment ratings per carriage - figures LRM simply does not list, so on LRM we verify ratings model by model. For short travels where crossed-roller rigidity outweighs stroke, compare LGC instead. Run this checklist against your drawing: complete-set form, 12 mm rail width, long carriage, one carriage on a 445 mm rail, preload B light (easier running, a little more compliance), accuracy P precision, top-mount direction. Grinding or finish-milling the mating surfaces is part of the deal at precision grade. If a future carriage-only replacement is planned, its pairing code must match the rail - we stock very few carriage-only items, so treat that as a special order. Send your load, moment and stroke figures with the RFQ and we will confirm suitability for this exact model.
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 LRM12L1X445S10BP FAQ
You receive a complete set: one 445 mm stainless-steel rail, 12 mm wide, with a single long carriage, top-mount fixing, preload B (light) and accuracy grade P (precision). Torque figures from the catalogue: M2 screws at 58.8 N.cm into steel, 39.2 into cast iron, 29.4 into aluminium; M3 screws at 196, 127 and 98 N.cm respectively. Ambient limit is 80 C, peaking to 100 C momentarily. Re-grease every 100 km or every 3 to 6 months. AirTAC publishes no load or moment ratings for the LRM series - we confirm those numbers for this specific model through your RFQ before you order.
Prepare the mounting surface by grinding or finish milling - the rated travel accuracy of a grade P guide assumes it. Either side of the rail may be used as the datum face; pick one and reference all measurements from it. Drive the top-mounted screws to the torque figures for your screw size and base material, checking alignment over the full 445 mm before final tightening. Do not strike the rail to nudge it into place - hidden damage can spoil accuracy and life. Wipe off the rust-preventive oil and charge the carriage with fresh lubricant before first use, and never mix lubricant types.
