Airtac LRM Miniature Linear Guide LRM12L1X195S10BH
The AirTAC Airtac LRM Miniature Linear Guide LRM12L1X195S10BH 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 LRM12L1X195S10BH
LRM12L1X195S10BH is a complete miniature linear guide set: one 12 mm wide stainless steel rail, 195 mm long, carrying a single long-series recirculating-ball carriage. The S10 code sets the 10 mm offset of the tapped end holes, and the absence of a trailing T means the rail fixes from the top. Preload is grade B, the light option, so the carriage runs noticeably freer than a medium-preload block - a good match for smooth hand or motor-driven moves rather than rigid loaded positioning.
The long carriage stretches the bearing span and spreads the running load over more recirculating balls, giving any tipping component a longer, steadier footprint. Like every LRM guide it uses a common rail profile shared by other LRM12 carriages, ball retention to keep the ISO 3290 G10 Japanese balls in place during handling, a double-lip seal for grease retention and dust exclusion, and an outer cover over the screw line. Ambient temperature must stay at or below 80 C, with peaks no higher than 100 C. AirTAC publishes no load or moment rating for the LRM series, so we confirm the figures for this exact model before you order - send the RFQ and we will come back with the datasheet values.

Where the Airtac LRM Miniature Linear Guide LRM12L1X195S10BH Is Used
Benchtop microscope stage
A sample carrier gliding under a stereo microscope in an electronics lab, where the long carriage keeps a small inspection fixture level across the 195 mm stroke.
Micro-dispensing head
A nozzle carrier on a small conformal-coating or glue-dot machine, guided at light preload so bead placement stays repeatable pass after pass.
Compact XY positioning stage
The linear axis of a small two-axis benchtop stage moving a laser-diode or camera module between test positions in an optics lab.
Is the Airtac LRM Miniature Linear Guide LRM12L1X195S10BH the Right Guide?
Size up to the LSH series when the applied load is substantial or cantilevered: LSH publishes per-carriage dynamic, static and moment ratings you can put straight into a calculation, which LRM does not. If travel is short and the job needs crossed-roller rigidity, LGC is the better cross-over. Before committing, check the whole code: form (this is a set with the rail included), 12 mm rail width, long carriage, one block, 195 mm rail, preload B (free-running, less rigid, more forgiving of mounting error), accuracy H, top-mount rail - and confirm the load rating with us first. A practical bonus: 924 of the 988 LRM sets we stock are size 12, so this configuration usually ships faster than any other in the range.
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 LRM12L1X195S10BH FAQ
The rail is 12 mm wide and 195 mm long, high accuracy grade H, top-mounted, with one long carriage and light preload B. M2 screws torque to 58.8 N.cm into steel, 39.2 N.cm into cast iron and 29.4 N.cm into aluminium (M3: 196, 127 and 98 N.cm). The carriage ships greased with Kyodo Yushi PS No. 2 and needs re-greasing every 100 km of travel or every 3 to 6 months. Ambient temperature must not exceed 80 C, with transient peaks to 100 C. Load and moment ratings are not published for LRM; we confirm them per model - ask via RFQ.
Both parts come in the box: the 195 mm stainless steel rail and one long carriage, factory-matched with light preload B. It is not a carriage-only spare, and it is not interchangeable with the bottom-mount (T) version of the same size. If you later need a replacement block, note that we stock only four carriage-only SKUs, so most swaps are a special order matched by pairing code.
