Lubrication is the key to continued performance and reliability of bearing assemblies. LBL-1 is a multi-purpose pure synthetic lubricant. The stable and predictable chemical properties of LBL-1 help it last longer and outperform conventional petroleumbased greases and oils. Lubricant additives fill microscopic surface irregularities to form a smooth, lubricated surface.
