Airtac LRM Miniature Linear Guide LRM12N1X135S17.5AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X135S17.5AH 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 LRM12N1X135S17.5AH
This AirTAC LRM12N1X135S17.5AH code specifies a matched miniature guide: a 12 mm stainless-steel rail cut to 135 mm, whose first mounting hole sits 17.5 mm in from each rail end, carrying one standard carriage. The generous S17.5 offset spreads the end fixings further along the rail than the usual short offsets, which matters when your base plate already has a fixed hole pitch.
Like every LRM carriage, this one shares the common LRM rail profile, so a standard or long carriage from the same series can run on the same rail if you reconfigure later. Ball retention holds the balls in during handling - the balls are ISO 3290 G10 grade - and a double-lip seal plus outer cover keep grease in and debris out. Keep ambient temperature at or under 80 C, with brief peaks to 100 C. The wider end-fixing pitch also gives a 135 mm rail a more anchored footing at each end. Load and moment capacities are confirmed per model rather than published; send the RFQ and we will return the figures for this exact code.

Where the Airtac LRM Miniature Linear Guide LRM12N1X135S17.5AH Is Used
Semiconductor fixture transport
A short 135 mm axis moving trays or sockets between stations on a test bench, where the 17.5 mm end offset matches a standard fixture hole pitch.
Optical alignment stage
Fine positioning of a small mirror or lens holder, benefiting from H-grade accuracy and the free running of an unloaded preload A carriage.
Wire and harness routing guide
Guiding a lightweight camera or probe along a 135 mm path during cable assembly and inspection work.
Is the Airtac LRM Miniature Linear Guide LRM12N1X135S17.5AH the Right Guide?
If your application carries a substantial or cantilevered load, LRM will not let you verify it on paper - the AirTAC LSH series publishes dynamic, static and moment ratings for each carriage and is the better sizing tool. For very short travel where rigidity per millimetre matters, the crossed-roller LGC series is the alternative. Match checklist for this code: complete set (rail and carriage together), 12 mm rail width, standard carriage length, single carriage, 135 mm rail, S17.5 end offset, preload A (smoothest running, lowest rigidity of the three grades), accuracy H, top-mount installation - and confirm the load rating with us before you commit.
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 LRM12N1X135S17.5AH FAQ
Rail width 12 mm, stainless steel; rail length 135 mm; end-hole offset 17.5 mm; one standard-length carriage; preload A (none); accuracy H (high); top-mount rail. The carriage ships greased with Kyodo Yushi PS No. 2 and needs re-greasing every 100 km or 3 to 6 months. Screw torques are 58.8 N.cm for M2 and 196 N.cm for M3 into steel, lower into cast iron and aluminium. Maximum ambient temperature is 80 C, with brief peaks to 100 C. Load and moment ratings are not published for LRM; we confirm them for the specific model on request.
LSH is the larger series and it publishes basic dynamic load, static load and moment ratings per carriage, so a calculation can back the selection. LRM does not publish those figures; its case rests on a 12 mm envelope, smooth H-grade running and a stainless rail. If your customer wants documented load margins, move up to LSH. If the driver is size and smoothness in a light-duty stroke, LRM fits - and we will confirm the LRM figures per model via the RFQ.
