Where LMK8UU is used
- Guides an 8mm smooth or hardened round shaft through linear travel.
- Square flange provides a compact four-point mounting face.
- Closed bearing format suits supported-shaft layouts with access from the shaft end.
- Commonly used in compact CNC, automation, positioning and 3D-printer assemblies.
How to read the load ratings
Dynamic: 260N (about 27kgf equivalent force). Catalogue comparison value while the bearing is moving.
Static: 400N (about 41kgf 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 shaft support, alignment, mounting stiffness, travel speed, impact, load sharing and the complete machine design.
