Klüber staburags NBU 8 EP

For rolling bearings and high pressure

Klüber STABURAGS NBU 8 EP is a long-life bearing and high-pressure grease based on mineral oil with a barium complex thickener. The grease offers strong wear protection, is water-resistant and protects against corrosion and tribo-corrosion. Tested to SKF R2F (run B, 140°C) and achieves around 4,000 hours in the SKF-ROF test (120°C).

Applications

• Rolling bearings under high specific loads
• Suitable for traction motors, axle bearings, electric motors, pumps and tapered roller bearings

Benefits

• Good corrosion protection
• Resistant to environmental influences
• Strong EP/wear protection
• Protects against tribo-corrosion
• High-pressure grease for heavier loads
