KLUBER STABURAGS NBU 12 K – High-Performance Rolling and Plain Bearing Grease for Long-Term Protection

Industrial equipment continues to push the limits of speed, load, and reliability. To meet these growing challenges, Klüber Lubrication introduces KLUBER STABURAGS NBU 12 K, a high-performance specialty grease engineered for long-term lubrication of rolling and plain bearings under demanding operating conditions. Built on a robust formulation of mineral oil and barium complex soap, this grease delivers exceptional wear protection, corrosion resistance, and stability against water and ambient media.

1. Key Features & Benefits

According to official product data, KLUBER STABURAGS NBU 12 K offers:

• Excellent corrosion protection even under moisture exposure

• High wear protection for extended bearing life

• Good resistance to water and ambient media for stable lubrication

• Strong load-carrying capability suitable for heavy-duty applications

• Good sealing effect helping keep contaminants away

• High resistance to tribo-corrosion, reducing premature surface damage

2. Applications

 STABURAGS NBU 12 K is suitable for:

• Medium-speed rolling bearings

• Long-term and lifetime lubrication in industrial machinery

• Mechanical engineering applications

• Motors, power stations, and rotating equipment

• Rolling bearings requiring consistent protection under variable loads

Its balanced worked penetration (245–275 × 0.1 mm) and high drop point (≥220°C) make it reliable for elevated-temperature and moderate-speed environments.

3. Technical Highlights

• Service temperature: –15°C to +130°C

• Kinematic viscosity (40°C): approx. 220 mm²/s

• Water resistance: excellent

• Corrosion test (EMCOR): grade 0 (best possible result)

• Long shelf life: approx. 60 months

These properties demonstrate a strong combination of mechanical stability and resistance to water, oxidation, and external contaminants.

4. Why KLUBER STABURAGS NBU 12 K Stands Out

In industries where equipment uptime directly impacts production efficiency, KLUBER STABURAGS NBU 12 K provides both dependability and longevity. Its advanced barium complex formulation ensures stable lubrication films, longer relubrication intervals, and reduced maintenance downtime—making it a preferred choice for OEMs and industrial maintenance teams worldwide.
