Klüber staburags NBU 8 EP

For roller bearings and high pressure

Klüber STABURAGS NBU 8 EP is a long-lasting 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 tribocorrosion. It is tested according to SKF R2F (run B, 140°C) and achieves approximately 4000 hours in the SKF ROF test (120°C).

Applications

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

Advantages

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