Description

CASTROL MOLUB-ALLOY™ BRB 572 is a bearing grease, applicable for normal and elevated temperature (max. 120°C) and for long service intervals. Work and shear stability matches the service life of rolling bearings. Controlled mobility under “full pack” conditions act as a seal against contamination without excess churning and heat generation. • The base oils used in CASTROL MOLUB-ALLOY™ BRB 572 are high-quality mineral oils, containing inhibitors against rust and corrosion, and they are fortified against oxidation. • This unique grease is outstanding in shear stability and in controlled mobility under shear. This results from the selection of a most stable lithium thickening system and special manufacturing techniques. • Load carrying and antiwear properties beyond those of conventional greases result from chemical additives working synergistically with select CASTROL MOLUB-ALLOY™ lubricating solids, blended uniformly throughout the grease. The lubricating solids are most effective in protecting the machined surfaces of new bearings in critical running-in periods. Good bearing surfaces are essential to extended service life.

Application

• CASTROL MOLUB-ALLOY™ BRB 572 is an outstanding grease for all types of bearings (rolling, ball, roller bearings), including precision built. It is also used in general application, including journal bearings.
• “Full Pack Concept”: customarily, bearing manufacturers recommend packing bearings only 1/3 to 1/2 full to avoid churning, shear loss of consistency and overheating. In bearings with minimal grease capacity, CASTROL MOLUBALLOY™ BRB 572 can occupy effectively 60 % of this capacity.
• The bulk grease surrounding the action zone remains undisturbed, sealing out contaminants and minimizing “breathing” as a source of oxidation, water vapor and fine dust.
• In industrial operations the good sealing effect prevents dirt from entering the bearing.
• The outstanding physical and chemical stability of CASTROL MOLUB-ALLOY™ BRB 572 allows to extent relubrication intervals of bearings in inaccessible places.
