STABURAGS NBU 4 MF and STABURAGS NBU 12 MF are black lubricating greases based on mineral oil for rolling and plain bearings subject to high loads. The barium complex soap thickener ensures good adhesion of the grease to the lube point and thus good resistance to moisture and aggressive media. Both greases contain special solid lubricants based on MoS2, which improve emergency lubrication properties under high temperatures or loads.

STABURAGS NBU 4 MF has proven successful for the lubrication of high-speed rolling bearings in rolls, spindles, cam rollers and tensioning rollers. The grease is also used for bearings in compressors and deep drilling machines. STABURAGS NBU 12 MF is used for highly loaded bearings, e.g. joints, spline shafts, couplings as well as pumps and electric motors, for example in wood drying chambers. Both greases are also suitable for steel-on-steel material combinations in slideways and plain bearings.
