Airtac LRM Miniature Linear Guide LRM12L1X370S10BP
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X370S10BP 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 LRM12L1X370S10BP
The P in LRM12L1X370S10BP sets this item apart from the high-accuracy version: precision grade tightens the manufacturing tolerances of the guide pair, which matters when a measurement probe or optical axis must land repeatably. You receive a 12 mm wide stainless-steel rail, 370 mm long, with one long recirculating-ball carriage already fitted, mounted from the top in the standard way.
AirTAC builds the LRM carriage around ISO 3290 G10 Japanese steel balls for roundness, retained in the carriage so they cannot fall out during handling, with a double-lip seal and an outer cover doing the oil-scraping and dirt-exclusion work. Worth knowing before you buy: across our stocked range the price is driven far more by rail length and carriage count than by rail width, so a 370 mm rail sits well above the short-run end of the scale. Ambient temperature must stay at or below 80 C with only transient peaks to 100 C - keep it clear of oven walls and laser heads. As with every LRM item, load capacity is confirmed per model from the datasheet; ask us via the RFQ and we will return the figure.

Where the Airtac LRM Miniature Linear Guide LRM12L1X370S10BP Is Used
Gauge comparator stand
A small workshop comparator slides its dial-indicator carriage along the rail; precision P grade keeps the indicator position repeatable from one measured part to the next.
Laser diode test bench
Aligning a diode package to a fibre takes sub-millimetre nudges; the long carriage on light preload glides with low drag so fine adjustments do not fight the operator.
Wire-feed guide head
A compact wire-processing machine carries its feed head on this rail; the double-lip seal keeps wire dust out of the raceways between lubrication rounds.
Is the Airtac LRM Miniature Linear Guide LRM12L1X370S10BP the Right Guide?
This is the precision-grade, top-mount, light-preload build of a complete set: 12 mm rail, 370 mm long, one long carriage. Precision P grade buys tighter running tolerances than H; light preload B keeps drag low but leaves a little more play than grade C would. If your sizing depends on published numbers, LSH is the step up - it lists per-carriage dynamic, static and moment ratings that LRM omits. If the travel is short and you need crossed-roller rigidity instead, look at LGC. Before ordering, tick off the checklist: form (set), rail width, carriage length, carriage count, rail length, preload, accuracy, mounting direction - and confirm the load rating with us, since LRM publishes none.
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 LRM12L1X370S10BP FAQ
It is a complete set: one 12 mm wide, 370 mm long stainless-steel rail with a single long carriage fitted, top-mount, light preload B, precision P accuracy. No separate rail or dummy parts are needed. If you later want only a spare carriage, be aware we carry just four carriage-only SKUs from stock, and rails and carriages must share a pairing code - send the full model code when you enquire.
Confirmed from the code: rail width 12 mm, rail length 370 mm, one long carriage, preload B (light), accuracy P (precision), top-mount rail. Installation limits we can state: M2 screws torque at 58.8 N.cm and M3 at 196 N.cm into steel, with lower values into cast iron and aluminium; ambient temperature must not exceed 80 C, briefly 100 C; re-grease every 100 km or 3 to 6 months. What is not published is any load or moment rating for LRM - we confirm those per model, so request them with your RFQ.
