Airtac LRM Miniature Linear Guide LRM12N1X145S10CH
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X145S10CH 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 LRM12N1X145S10CH
LRM12N1X145S10CH is a complete LRM miniature guide: a 145 mm stainless-steel rail, 12 mm wide, carrying one standard-length recirculating-ball carriage. No trailing letter in the code means top-mount - you fasten the rail from above into its fixing seats, the quickest arrangement to align on a machined base.
Preload C is the firmest grade offered on LRM; it stiffens the carriage against play at the cost of slightly higher drag, a sensible pick where backlash matters more than free sliding. Accuracy grade H suits general precision positioning. The balls circulating in the carriage are Japanese-made to ISO 3290 G10 - that grade covers the balls alone, not the assembled guide. Keep the ambient at or under 80 C, with transient peaks to 100 C. No load or moment rating is published for this series; we will confirm the numbers for this exact configuration when you send the RFQ.

Where the Airtac LRM Miniature Linear Guide LRM12N1X145S10CH Is Used
Small pick-and-place head
Guiding a light vacuum gripper across a PCB panel: 12 mm is the best-stocked size in this range, with well over 900 sets on the shelf, so a build laid out around this rail ships quickly.
Benchtop dispensing axis
The slide under a solder-paste or glue needle on a compact dotting machine, where the firm C preload holds position during the needle dwell.
PCB carrier shuttle
Moving a circuit-board carrier between test and firmware stations on a desktop cell, with the H grade keeping the repeat line consistent station to station.
Is the Airtac LRM Miniature Linear Guide LRM12N1X145S10CH the Right Guide?
AirTAC publishes no load, moment or running-parallelism figures for LRM, so if the axis sees real weight or an overhung arm, step up to LSH - its catalogue lists dynamic, static and moment ratings per carriage that you can size against directly. For short travel where crossed-roller rigidity is the priority, LGC is the alternative family. Ordering checklist for this CH set: form complete with rail, 12 mm rail width, standard carriage, one block on 145 mm of rail, preload C (more rigid, less forgiving of mounting error), accuracy H, top-mount, and a load rating confirmed with us before commit. Note also that stocked price tracks rail length far more than rail width, so trimming travel trims cost.
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 LRM12N1X145S10CH FAQ
Rail width 12 mm, rail length 145 mm, one standard carriage, preload C (medium), accuracy H (high), top-mount mounting. Mounting-surface rows are tabulated per size (Q1 2 to 5 mm, Q2 1.2 to 3.2 mm, H1 1.5 to 3.5 mm, edge R max 0.2 to 0.5 mm) - use the row for your size on a ground or finish-milled surface. Ambient limit 80 C with peaks to 100 C; re-grease every 100 km of travel or every 3 to 6 months. No load or moment rating is published for LRM - we confirm it per model.
Pick LRM12N1X145S10CH when the envelope is tight and the duty is light-precision positioning. Choose LSH when the load is substantial or overhung: LSH publishes dynamic, static and moment ratings per carriage, while LRM publishes none, so an LSH axis can be calculated rather than confirmed case by case. For short travel needing crossed-roller stiffness, compare LGC. Send us the axis details and we will confirm the load rating for this LRM model before you buy.
