Airtac LRM Miniature Linear Guide LRM12N1X95S10BHT
The AirTAC Airtac LRM Miniature Linear Guide LRM12N1X95S10BHT 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 LRM12N1X95S10BHT
LRM12N1X95S10BHT is a bottom-mount version of the LRM12 miniature guide: a 95 mm stainless rail, 12 mm across, with one standard recirculating-ball carriage, preloaded to grade B. Bottom-mounting is chosen when the machine deck gives no access from above - the rail bolts through its underside, leaving the top face unobstructed.
Accuracy grade H is the practical choice for a working machine axis that wants high precision without the cost of P grade. Ball retention keeps the ISO 3290 G10 balls (a ball-only grade) captive during handling, yet the maker still warns that angling the carriage on or yanking it off can shed balls, so work slowly. The double-lip seal and outer cover keep chips and swarf away from the raceways. Ambient heat must not exceed 80 C, with short peaks to 100 C. No load or moment figures are published for LRM; request them per model through our RFQ and we will confirm.

Where the Airtac LRM Miniature Linear Guide LRM12N1X95S10BHT Is Used
Packaging line sensor rail
A form-fill-seal packaging machine carries its film-edge sensor on a rail fixed from below, where the deck surface above is buried under guarding.
Wire-cutting feed slide
A wire-processing bench feeds cable through a cutter on the short 95 mm slide; grade H accuracy keeps the feed path aligned stroke after stroke.
Laser lab alignment stage
A laser-lab alignment stage repositioned during set-up; the ball-retention design lowers the chance of dropped balls when the carriage is lifted off, though a dummy rail remains good practice.
Is the Airtac LRM Miniature Linear Guide LRM12N1X95S10BHT the Right Guide?
Sizing advice: LRM carries no published load or moment ratings, so if the application approaches the heavier end or hangs a cantilever, choose AirTAC LSH instead and size from its per-carriage dynamic, static and moment tables. If the travel is brief and rigidity from crossed rollers is the priority, look at LGC. This particular SKU is a complete set with the rail included, 12 mm rail width, standard carriage, one carriage on a 95 mm rail, light preload B, accuracy H, and bottom-mount fixing. The same checklist applies to any purchase: form, width, carriage length, count and rail length, preload, accuracy, mounting direction, pairing code for carriage-only buys - plus a load-rating confirmation with us.
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 LRM12N1X95S10BHT FAQ
Key figures: 12 mm rail width; 95 mm rail; one standard carriage; preload B, the light grade; accuracy H; bottom-mount fixing via the trailing T; 10 mm end-hole offset. Machine the seating ground or finish-milled, and torque M2 screws at 58.8 N.cm and M3 at 196 N.cm into steel. The environment must not exceed 80 C, with brief peaks to 100 C. Re-lubricate with Kyodo Yushi PS No. 2 after every 100 km of travel or within 3 to 6 months, in the quantity listed per model. No load or moment rating is published for LRM; we confirm it model by model - use the RFQ.
The trailing T sets bottom-mount fixing: the rail bolts through its underside, for decks where the top face is buried or off-limits. Whatever the direction, seat the rail on a ground or finish-milled surface or the rated travel accuracy is lost; either side of the rail can serve as the datum, and with more than one carriage keep all datum faces on the same side. Do not hammer the rail into position - an unnoticed knock can spoil accuracy and life without leaving visible damage.
