💡 Why are thrust ball bearings used for vertical or axial load support?
They manage straight-line forces along the shaft without adding drag to the rotation.
- They keep axial motion stable under heavy loads
- They allow smooth turning even with strong downward pressure
- They fit compact housings where only axial forces need control

This Nachi bearing delivers clean axial support and smooth rotation for any setup that carries vertical load.
