document summary

As a lubrication solution designed for extreme high-speed and high-precision operating conditions, the NBU 15 is uniquely formulated and proven to solve the lubrication challenges of high-speed bearing systems, extend equipment life, improve operational reliability, and ultimately reduce total cost of ownership for users.

1. Introduction: The lubrication challenge in the high-speed era

As the modern manufacturing industry continues to develop towards high speed, high precision and high efficiency, bearings in machine tool spindles, textile machinery, precision transmission systems and other equipment are facing increasingly severe operating conditions. The temperature rise, centrifugal force, fretting wear caused by high-speed operation, as well as multi-media environments such as coolant and metal chips, pose all-round challenges to the performance of grease. Traditional greases are often lost, oxidized at high temperatures, or thrown out at high speeds, resulting in lubrication failure and increased bearing wear, which in turn leads to equipment downtime and high maintenance costs.

The NORBERT NBU 15 was developed to meet these challenges head-on. It is not just a grease, but a proven protection solution for high-speed bearing systems.

2. Product core features and technical analysis

2.1 Built for high speed

• Exceptional high-speed retention: Its unique uniform short fibrous structure, combined with an optimized thickener and base oil system, allows it to adhere firmly to the bearing raceway at speeds of up to 1,600,000 mm/min (n x dm), resisting centrifugal forces and avoiding lubrication failure.
  

• Exceptional temperature control performance: Selected synthetic oil and ester oil composite base oil, with stable viscosity under high-speed shearing, can effectively reduce friction and temperature rise during bearing operation, thus protecting the metallographic structure and dimensional stability of bearing steel.
  

2.2 Extreme protective performance

• Composite barium-based thickener system: Gives the product excellent corrosion resistance, water resistance and medium resistance. It can form a long-lasting protective film on the metal surface even in humid or in contact with cutting fluid, and the SKF-EMCOR test results (corrosion class ≤1) prove its excellent corrosion resistance.
  

• Wide temperature adaptability: Operating temperatures range from -40 ° C to 230 ° C, with drop points above 280 ° C, ensuring that the grease structure does not collapse or harden severely under extreme conditions of severe cold start-up or high temperature continuous operation.
  

2.3 Long-lasting and reliable lubrication guarantee

• Optimized anti-wear and extreme pressure performance: The special additive formulation provides excellent load resistance, even under heavy or impact loads, it can effectively prevent the wear of bearing raceways and rolling elements, and significantly extend the service life of bearings.
  

• Excellent oxidation resistance: effectively delays the oxidation process of base oil at high temperatures, prevents the formation of acidic substances, and ensures the stable performance of grease during long-term use, with a maximum shelf life of 36 months.
  

3. Typical application fields

The NORBERT NBU 15 is ideal for lubricating bearings on the following high-speed, precision equipment:

• High-speed machine tool spindle: machining center, numerical control milling machine, precision lathe spindle bearing.
  

• Textile machinery: spindles and rolling bearings for high-speed spinning spindles, winders, looms.
  

• Precision transmission system: high-speed ball screw bearing, linear guide slider, precision gear pair (such as helical gear).
  

• Other high-speed equipment: high-speed motor bearings, precision instrument spindles, electric valve brakes and other high-speed components.
  

4. Key physical and technical parameters

5. Guidelines for use and construction

• Lubrication method: suitable for manual/automatic grease gun, grease injection cylinder, brush or scraper smearing and other methods.
  

• Compatibility Tip: Although the product has good compatibility, it is recommended to conduct a compatibility test with the specific artificial rubber or plastic seal material in the equipment before formal use.
  

• Cleaning and replacement: Before adding new grease, the old grease and dirt should be removed as much as possible. The amount of filling should refer to the equipment manufacturer's suggestion to avoid excessive filling resulting in excessive temperature rise.
  

• Storage conditions: Please store in a cool and dry place away from frost and direct sunlight. Please seal the container after use.
