HP Crushfine 60 NB-II is a high viscosity, bitumen-free industrial lubricant specially formulated for the demanding environment of sugar mill roll bearings. It is designed to perform under extreme pressures, shock loading, and severe contamination caused by cane juice, water, dust, and bagasse during the crushing process. In sugar milling, shredded cane passes through grooved or corrugated rolls that apply tremendous hydraulic pressure through rams and pressure plates. These forces transfer directly to the roll bearings, where high pressure and irregular cane feeding generate severe shock loads. Without a strong lubricating film, metal-to-metal contact, overheating, and premature bearing failures are inevitable. HP Crushfine 60 NB-II forms a robust, adhesive lubricating film that separates shafts and bearings, resists washout, and maintains integrity even under heavy contamination. It provides consistent lubrication for plain journal bearings (mill brasses), ensuring oil grooves remain effective and bearings are protected across their full length.
