The complete source sheet below identifies the short SBRXUU family. The translated row is the exact SBR12UU reference; catalogue basic load values are shown in Newtons with a simple kgf equivalent.
| Model | Bore | h | E | W | L | F | h1 | Angle | B | C | Thread | L1 | T | Insert | Dynamic C | Static C0 | Weight |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| SBR12UU | 12mm | 17.5mm | 20.5mm | 41mm | 39mm | 28mm | 7.5mm | 80° | 28mm | 26mm | M5 | 10mm | 9mm | LM12UU-OP | 420N ≈ 43kgf | 610N ≈ 62kgf | 100g |
Where SBR12UU is used
- Runs on a compatible 12mm SBR supported round rail.
- Short housing suits compact carriage plates and closer mounting points.
- Open underside allows the bearing to pass over the aluminium rail support.
- Commonly used in CNC, automation, positioning and workshop linear-motion assemblies.
How to read the catalogue ratings
Dynamic: 420N (about 43kgf equivalent force). Catalogue comparison value while the bearing is moving.
Static: 610N (about 62kgf equivalent force). Catalogue comparison value while the bearing is stationary.
These are bearing basic load ratings, not lifting ratings or guaranteed working payloads. Actual usable load depends on rail support, carriage spacing, alignment, mounting stiffness, travel speed, shock and the complete machine design.
