Frequently Asked Questions
Q: Why is KLÜBER Staburags NBU preferred in steel mills?
The barium complex thickener in Staburags NBU provides unique water displacement — water beads up and rolls off rather than penetrating to the metal surface. In steel mills with high-pressure descaling water spray (up to 400 bar), this water-displacing property is critical for bearing protection. The MoS₂ solid lubricant provides backup lubrication during boundary conditions. This combination of properties has made Staburags NBU the industry standard in steel mill bearing lubrication for decades.
