WR 2
WR 2 — modern high-temperature water-resistant grease of a new generation with exceptionally high performance characteristics. It is produced based on high-quality mineral base oil and a lithium complex thickener developed using the original technology of “RIMOL” S.P.A. The grease formulation provides extremely high water resistance, thermal stability, and improved anti-corrosion properties, while maintaining excellent pumpability and lubricating ability across a wide range of operating speeds. The presence of special functional EP additives ensures effective performance under extreme conditions.
The physicochemical indicators of lubricating properties comply with the requirements applied in the classification system of greases for long-term lubrication of compact bearing units (Hub Unit) ZF TE-ML 12H.
