Airtac LRM Miniature Linear Guide LRM12L1X98S24AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X98S24AH 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 LRM12L1X98S24AH
The LRM12L1X98S24AH is a complete miniature linear guide from AirTAC, delivered as one item: a 12 mm wide stainless-steel rail, cut to 98 mm, with a single long recirculating-ball carriage fitted. Fixing holes sit on top of the rail, with the first hole 24 mm in from the rail end, so a compact slide can run close up to a machine wall on one side.
Because the carriage is the long type, its ball circuit has a longer footprint than a standard block, which steadies the ride on the short 98 mm rail. AirTAC fits a double-lip seal plus an outer cover for oil retention and dust exclusion, and the recirculating balls themselves are Japanese-made to ISO 3290 G10. Ambient temperature must stay at or below 80 C, with transient peaks no higher than 100 C - worth checking on any benchtop build with warm electronics nearby. Do not expect load figures from a datasheet summary: LRM publishes none, so we confirm the rating for this exact code before you order. Send the RFQ and we will reply with the confirmed numbers.

Where the Airtac LRM Miniature Linear Guide LRM12L1X98S24AH Is Used
Laser diode alignment slide
A compact alignment slide carrying a laser diode and lens on a benchtop optics rig, where the 98 mm rail keeps the stage footprint small and the long carriage damps vibration on short moves.
Desktop SMD prototyping head
A light pick-up head on a desktop SMD prototyping station: the single long carriage gives a small nozzle a steadier platform, and preload A leaves the travel at its smoothest for gentle placement.
Microscope sample positioning
A sample table under a stereo microscope in a QC lab, where high-accuracy grade H travel and the 80 C ambient ceiling suit quiet, room-temperature inspection work.
Is the Airtac LRM Miniature Linear Guide LRM12L1X98S24AH the Right Guide?
At 12 mm rail width, this is the small end of AirTAC's guide range, chosen for precision travel in a tight envelope rather than for heavy carry. When the load is substantial or cantilevered, move up to LSH instead: that series publishes per-carriage dynamic, static and moment ratings you can plug straight into a sizing calculation, which LRM cannot offer. Where travel is short and crossed-roller stiffness matters more than long runs, LGC is the cross-series alternative. Your checklist for this code: complete set form, 12 mm rail width, long carriage, one block, 98 mm rail length, 24 mm end offset, preload A (none - the easiest to install and the loosest feel), accuracy H, top-mount rail - then confirm the load rating with us before committing.
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 LRM12L1X98S24AH FAQ
It is a complete set: 12 mm rail width, 98 mm rail length, one long carriage, preload A (none), accuracy grade H (high), top-mount rail, and a 24 mm offset between the rail end and the first hole. Fit M2 screws at 58.8 N.cm into steel, 39.2 N.cm into cast iron or 29.4 N.cm into aluminium, and keep ambient temperature at or below 80 C with peaks no higher than 100 C. Re-grease every 100 km of travel or every 3 to 6 months. Basic dynamic, static and moment load ratings are not published for the LRM series, so we confirm them for this exact model before you order.
No. LSH is a larger series that publishes per-carriage dynamic, static and moment ratings, so you can check a load against a table. LRM publishes no ratings at all - it is picked for size, precision and smoothness in light-duty positioning, and the load for this code is confirmed with us per model. If your machine carries a real working load or a cantilever, LSH is the safer sizing path; if the envelope is tight and the duty is light, this 12 mm set is the quicker one to buy.
