Premium Single Unit Cross Roller Bearing For CNC Tables
✔️ XSU080318 model tracks at 280x355x25.4mm for air build

This single pack rotary bearing delivers precise angular motion for indexing CNC milling tables and custom automation rigs. It takes heavy radial and thrust loads while keeping friction low for smooth daily shop operations.

✅ Cross roller configuration locks rotational accuracy during machining cycles
✅ Air compatible housing reduces drag and extends service life
✅ Steel rings paired with precision ground rollers resist wear under load
✅ Direct replacement fit for standard table indexer mounting patterns

💡 What advantages does a cross roller rotary bearing bring to CNC milling indexes?

Keeping your machine running slick is why builders pick this design. It makes swapping fixtures handy because the crossed rollers share the load evenly.

- High rigidity holds positional accuracy during aggressive cut cycles
- Low start up torque allows quick indexing without losing step sync
- Sealed internal geometry blocks coolant and chips from damaging the tracks
