Airtac LRM Miniature Linear Guide LRM15L1X125S22.5AH
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X125S22.5AH is a miniature linear guide on a 15 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 LRM15L1X125S22.5AH
LRM15L1X125S22.5AH is a complete set: a stainless-steel rail 15 mm wide and 125 mm long, with one long recirculating-ball carriage supplied fitted. What sets it apart is the 22.5 mm end-hole offset - the first mounting hole sits 22.5 mm in from the rail end, a less common position that suits base plates with a wider set-back at the edge. Verify the figure against your machine drawing before ordering.
Because replacing a carriage later usually means a special order - we stock only a handful of carriage-only SKUs - it pays to get this exact configuration right the first time. The carriage's ISO 3290 G10 balls are held by the ball-retention design, but the manufacturer is clear that angled insertion or rapid fitting and removal can still drop balls; a dummy rail makes safe swaps much easier. The double-lip seal retains grease and excludes dust, the outer cover protects the seal strip, and the common LRM15 rail profile means any LRM15 carriage shares this rail. Keep the ambient temperature at or below 80 C, with transient peaks to 100 C. No load or moment ratings are published for LRM; we confirm capacity for this exact model through the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM15L1X125S22.5AH Is Used
Small dispenser head carriage
A benchtop adhesive dispenser on a 125 mm axis deposits beads along a housing seam; the long carriage lengthens the bearing span and steadies the head against tip load.
Wire feed guide on a cut-and-strip machine
A wire processing bench guides stripped leads to the terminal press; the stainless rail shrugs off workshop conditions while the carriage tracks light pulling loads.
Compact pill counting shuttle
A pharmacy automation shuttle makes short, fast strokes between a hopper and a vial; cycled continuously, a stroke this short still reaches the 100 km re-grease point in weeks, so the distance binds before the calendar does.
Is the Airtac LRM Miniature Linear Guide LRM15L1X125S22.5AH the Right Guide?
The deciding question is always the load, and LRM gives you no published rating to size against - we confirm it per model. For heavy or cantilevered duty, choose LSH instead: its catalogue lists per-carriage dynamic, static and moment ratings. For a short stroke needing crossed-roller rigidity, LGC is the cross-series answer. Before ordering, work through: complete set (rail included), 15 mm rail width, long carriage, one block, 125 mm rail, preload A (none - least running resistance and easiest fitting, at the cost of rigidity), accuracy H, top-mount fixing, 22.5 mm end offset. A future carriage-only replacement must match the pairing code marked on the original part. Confirm the load rating with us via RFQ 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 LRM15L1X125S22.5AH FAQ
Rail width 15 mm; rail length 125 mm; one long (L) carriage; preload A (none); accuracy grade H; top-mount rail mounting; end-hole offset 22.5 mm. Fixing torque: M3 screws 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium; M2 screws 58.8, 39.2 and 29.4 N.cm respectively. The ambient temperature must not exceed 80 C, with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months, whichever comes first. Dynamic load, static load and moment ratings are not published for LRM - we confirm them for this specific model via the RFQ.
It is one of the less common catalogue positions - most LRM15 sets in our stock use smaller offsets - so measure your base plate's first hole row before ordering. On handling: the ball-retention design keeps the ISO 3290 G10 balls captive during normal care, but inserting the carriage at an angle or swapping it quickly can still drop balls, and on an inclined rail the carriage can slide off under its own weight. Use a dummy rail for carriage changes and hold the carriage at all times. Replacing the carriage later usually means a special order, since our carriage-only stock is very small.
