    Lubricating greases with excellent wear resistance.

    STABURAGS NBU 4, 12 are lubricating greases based on mineral oil and barium complex soap. These products are resistant to very high specific surface pressure, thus ensuring good wear protection. In addition, they are resistant to corrosion, water and many diluted alkaline and acid solutions.

    • STABURAGS NBU 4 has been used successfully on high-speed rolling bearings exposed to humidity or ambient media. It is suitable for rolls, spindles, cam rollers, tensioning rollers and motors.
    • STABURAGS NBU 12 is efficient on medium-speed rolling bearings subject to humidity or ambient media. It is used on water pumps, wheel bearings and motors; and in the textile industry, on all wet processing equipment such as washing, mercerising and dyeing machines.
    • These greases are applied by brush, spatula or conventional metering systems.
    • STABURAGS NBU 12 is also available in our automatic lubricant dispenser Klübermatic. Please consult the application engineering experts from Klüber Lubrication to determine whether Klübermatic might be used under the conditions in your processes.
    • Good corrosion protection
    • Good resistance to ambient media
    • Excellent wear protection
    • Good resistance to tribo-corrosion
    • Good load-carrying capacity
    • Good sealing effect
