Airtac LRM Miniature Linear Guide LRM15L1X200S14AH
The AirTAC Airtac LRM Miniature Linear Guide LRM15L1X200S14AH 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 LRM15L1X200S14AH
LRM15L1X200S14AH is a complete set in the AirTAC LRM miniature series: a 15 mm wide stainless-steel rail, 200 mm of it, carrying one long recirculating-ball carriage. Grade A means no preload, so this is the freest-running version of the block - the pick when low sliding resistance matters more than eliminating every trace of internal play. It arrives assembled and pre-filled with Kyodo Yushi PS No. 2 grease, ready for top-mount fixing.
The ball-retention design is a handling aid, not a guarantee: even with the balls held captive, seating the carriage at an angle or swapping it in a hurry can still drop them, so plan on a dummy rail if your maintenance routine involves frequent carriage changes - and note that carriage-only LRM items are thin on the ground, with most spare blocks needing a special order. The balls are Japanese-made to ISO 3290 G10, a grade that covers the balls alone; the double-lip seal and outer cover handle oil retention, dust and screw concealment. Keep ambient temperature at or under 80 C, with brief peaks to 100 C. AirTAC publishes no load or moment rating for LRM, so we confirm the figures for this exact set when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM15L1X200S14AH Is Used
Fiber-optic alignment stage
A 200 mm axis walks a fiber chuck into alignment with a photonic component; the free-running A-grade block gives the fine, low-friction motion manual alignment demands.
Gauge and fixture rebuilds
Workshops rebuilding small measuring jigs fit this stainless set where the old worn slide sat; grade H accuracy brings the fixture back into spec without redesigning it.
Small dispensing head traverse
A lightweight glue nozzle crosses a 200 mm span over an electronics panel, with the long carriage resisting the tipping pull of an offset hose and head.
Is the Airtac LRM Miniature Linear Guide LRM15L1X200S14AH the Right Guide?
Because grade A carries no preload, match it to a mechanism that tolerates a little play - if the duty needs zero-play stiffness, this same geometry exists with preload B or C. If the real problem is a heavy or overhung load, no preload grade will fix it: move up to LSH, whose per-carriage dynamic, static and moment ratings are published and can be checked on paper, or look at LGC for short-travel crossed-roller rigidity. The ordering checklist for this SKU: complete set, 15 mm rail, long carriage, one block, 200 mm rail length, no preload, accuracy H, top-mount fixing, and a load rating confirmed with us. Mounting surfaces should be ground or finish-milled - the catalogue lists edge-distance and flatness rows (Q1, Q2, H1 and corner radius) per size, so ask us for the row that applies to your rail.
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.

Specified: 15 mm rail width, 200 mm rail length, one long carriage, no preload (grade A), high accuracy (grade H), top-mount rail, stainless rail. Fixing torque: M3 screws 196 N.cm into steel, 127 into cast iron, 98 into aluminium; M2 screws 58.8, 39.2 and 29.4 N.cm. Ambient limit 80 C with transient peaks to 100 C. Re-grease every 100 km of travel or every 3 to 6 months, with the grease volume stated per model. Not specified anywhere in the catalogue: dynamic, static and moment load ratings for LRM - we confirm those for this model before you order.
Reasonably careful, even though the ball-retention design holds the balls in place during normal handling. The manufacturer is explicit that inserting the carriage onto the rail at an angle, or fitting and removing it in a hurry, can still release balls, and that a dummy rail makes safe carriage swaps much easier. Also hold the carriage when the rail is inclined, since it can slide off under its own weight, and never dismantle the block - dismantling risks lost balls, raceway damage and lost accuracy. For spares, ask us: carriage-only LRM parts are rarely held and usually need a special order with the pairing code off your rail.
