Castrol Alpha SMR NB Heavy is a high-performance lubricant specifically formulated for heavily loaded, slow-speed mill roll bearings in sugar mills. It is blended from highly refined steam cylinder oil and heavy brightstock base oils, incorporating special performance boosters to enhance load-carrying properties and film strength, thereby preventing wear and corrosion under various operating conditions. The superior demulsification feature ensures efficient lubrication even in the presence of sugar cane juice, and its excellent resistance to water washout is attributed to its higher viscosity and special compounding agents. citeturn0search3
