Airtac LRM Miniature Linear Guide LRM12L1X60S5AH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X60S5AH 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 LRM12L1X60S5AH
LRM12L1X60S5AH packs the LRM miniature guide concept into 60 mm of stainless-steel rail, 12 mm wide, with one long recirculating-ball carriage, a 5 mm end-hole offset, no preload and H-grade accuracy, mounted from the top. This is the short end of the range: the whole set is barely longer than the carriage itself, so the usable stroke is only a few tens of millimeters and the mechanism envelope should be laid out around that.
Short sets like this sit at the affordable end of the LRM price span, because with only two rail widths in the range it is length and carriage count - not size - that move the price. The design points still apply in full: a common rail profile shared across LRM carriages, ball retention that keeps the ISO 3290 G10 balls (a ball-only grade) captive during fitting, a double-lip seal plus outer cover against dust, and an 80 C ambient ceiling with 100 C transients. One caution suits this SKU especially: the maker notes a carriage on an inclined rail can slide under its own weight, so hold the assembly while handling it. Load and moment ratings are not published for LRM; ask us and we will confirm the numbers for this exact model before you commit.

Where the Airtac LRM Miniature Linear Guide LRM12L1X60S5AH Is Used
Micro-dispensing head
A tiny dispenser valve that lifts and steps across connector pins on a PCB test bench, needing only a few millimeters of precise travel.
Clamp verification slide
A short-stroke positioner that advances a go/no-go gauge onto a machined part inside a compact automated clamping station.
Bench tool-setting fixture
A presetting slide on a benchtop tool-setting fixture, where a short, smooth, repeatable traverse against a dial indicator is the whole job.
Is the Airtac LRM Miniature Linear Guide LRM12L1X60S5AH the Right Guide?
If the load is anything more than light, or it overhangs, move up to AirTAC LSH - it publishes dynamic, static and moment ratings per carriage that LRM does not, and those published tables are the safe way to size a real load. If travel is short but stiffness must come from crossed rollers, LGC is the better match. When specifying this set, fix down: form (complete rail-and-carriage set), rail width 12 mm, long carriage, one carriage, 60 mm rail, preload A (none - smoothest running, but expect a little play on direction reversal), accuracy H, top-mount mounting. Also weigh the long carriage against the short rail: the body occupies much of the 60 mm, so confirm the usable stroke fits the mechanism, and confirm the load rating with us before ordering.
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 LRM12L1X60S5AH FAQ
12 mm stainless rail, just 60 mm long, carrying one long carriage; 5 mm end-hole offset; preload A (none); accuracy H; top-mount rail. Fix with M3 screws at 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium. Ambient temperature limit 80 C, transient peaks 100 C. Re-grease every 100 km of travel or every 3 to 6 months - at a stroke this short the kilometre count accumulates quickly, so the distance binds before the calendar does. Load and moment ratings are not published for LRM; we confirm them per model via RFQ.
Decide by load and envelope. LRM wins when space is tight and duty is light: a 12 mm rail, a miniature carriage and smooth low-drag travel. LSH wins when the load is real or overhung, because its catalogue publishes dynamic, static and moment ratings per carriage - numbers LRM does not publish, so we confirm LRM figures individually. For short travel with crossed-roller rigidity, compare LGC instead. Send us the load and stroke sketch and we will confirm which series and which exact model to order.
