Rolling bearing and high-pressure grease.
STABURAGS NBU 8 EP is a lubricating grease based on mineral oil and barium complex soap. It has been used successfully for many years as a long-term grease for bearings subject to high specific loads. Its good wear protection properties are enhanced by the barium complex thickener. STABURAGS NBU 8 EP protects reliably against corrosion and is resistant to water.
