staburags nbu 12 k

Rolling and plain bearing greases.

STABURAGS NBU 12 K, 30 K are lubricating greases based on mineral oil and barium complex soap. Both greases offer excellent corrosion protection, resistance to water and ambient media as well as wear protection, load-carrying capacity and resistance to tribocorrosion.

  • STABURAGS NBU 12 K is suitable for the long-term and lifetime lubrication of medium-speed rolling bearings, e.g. in mechanical engineering, power stations and motors. STABURAGS NBU 30 K is suitable for the long-term and lifetime lubrication of low-speed, highly loaded rolling and plain bearings, mechanical engineering, chemical industry and power stations.
  • These greases are applied by brush, spatula or conventional metering systems.
  • Good corrosion protection
  • Excellent resistance to ambient media
  • High wear protection
  • Good resistance to tribo-corrosion
  • Good load-carrying capacity
  • Good sealing effect
