Airtac LRM Miniature Linear Guide LRM12L1X195S10CPT
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X195S10CPT 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 LRM12L1X195S10CPT
LRM12L1X195S10CPT pairs the two demanding choices in the LRM catalogue on one axis: preload C, the medium grade that removes the most internal clearance, and accuracy P, the precision tier. The hardware is a 12 mm wide stainless-steel rail of 195 mm with a 10 mm end-hole offset, bottom-mounted per the trailing T, carrying a single long recirculating-ball carriage whose extra length spreads contact over more balls - useful where a carried part must not rock along the travel. Rail and carriage arrive assembled and grease-filled.
This is the configuration that rewards careful installation. Mounting surfaces should be ground or finish-milled, and the catalogue's seat-preparation figures (Q1 2 to 5 mm, Q2 1.2 to 3.2 mm, H1 1.5 to 3.5 mm, corner radius 0.2 to 0.5 mm, listed per size) should be checked as a set against your drawing. The recirculating balls are Japanese-made to ISO 3290 G10 - a grade for the balls themselves, not an assembly standard. Keep ambience below 80 C. A C preload is less forgiving of imperfect seating than the lighter grades, so torque the screws properly: 196 N.cm for M3 into steel. AirTAC publishes no load or moment table for LRM; ask us and we will return the confirmed figures for this configuration.

Where the Airtac LRM Miniature Linear Guide LRM12L1X195S10CPT Is Used
Optical fibre alignment slide
A single-axis slide aligning a fibre collimator to a photonic chip in a packaging station, where the medium preload and P-grade accuracy hold position between bonding steps.
Wafer metrology micro-stage
An inspection micro-stage inside a semiconductor metrology tool, carrying a small sensor head over 195 mm with bottom-mount fixing that keeps the top deck flush for optics above.
Lab-built camera bridge fixture
A measurement fixture on the lab bench where the long carriage supports a small camera bridge, and the firm preload keeps the bridge from rocking as it traverses the rail.
Is the Airtac LRM Miniature Linear Guide LRM12L1X195S10CPT the Right Guide?
Size up to AirTAC LSH whenever the load is heavy or overhung - LSH gives you published per-carriage dynamic, static and moment ratings to calculate against, while LRM offers no such table of its own. Choose LGC when the stroke is short and crossed-roller stiffness matters more than ball-smooth motion. For this SKU, tick through: complete set form; 12 mm rail width; long carriage; one carriage; 195 mm rail; preload C, which installs with less clearance but demands better surface preparation than the lighter grades; accuracy P; bottom-mount fixing. No pairing code applies to a set. Before you lock the design, confirm the load rating with us - the manufacturer states none, and we will verify the figure for this exact configuration against your duty.
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 LRM12L1X195S10CPT FAQ
Specifications at a glance: 12 mm rail width, 195 mm rail length, one long carriage, preload C (medium), accuracy P (precision), bottom-mount fixing, 10 mm end-hole offset. Screw torque: M3 196 N.cm into steel, 127 N.cm into cast iron, 98 N.cm into aluminium; M2 58.8, 39.2 and 29.4 N.cm respectively. Ambient limit 80 C, brief peaks to 100 C. Re-lubricate every 100 km of travel or every 3 to 6 months through the rear lubrication hole, using one grease type only. Load and moment ratings are not published for this series; we confirm them per model.
Choose LRM when the envelope is miniature and the duty is light - this set gives you a 12 mm rail with P-grade accuracy in a compact footprint. Choose LSH when you need published load, moment and rating data to run real sizing calculations, because LSH's catalogue lists per-carriage dynamic, static and moment values and LRM's does not. If you are unsure which side your duty falls on, send us the load, stroke and cycle rate and we will confirm figures for both routes.
