STEEL quakerchem.com | 1.800.523.7010 LUBRICATION OF FINISHING MILL ROLL BEARINGS QUAKERTEK™ VERKOMAX EP-12 THE SOLUTION CHALLENGES » A large steel mill, was currently using a grease in the roll bearings on their finishing mill, that was causing them to have 24 bearing failures a year » The mill wanted to make a change that would extend the lubrication periods, reduce grease consumption and even further reduce bearing failures © 2016 Quaker Chemical Corporation. All Rights Reserved. » Verkol Lubricants, a Quaker Chemical Company, assessed the mill’s situation, and introduced QUAKERTEK™ VERKOPLEX EP-2, a lithium complex grease, reducing bearing failures to 5-6 a year. » After 8 years of using QUAKERTEK™ VERKOPLEX EP-2, the mill wanted to run a trial with the main purpose of optimizing grease consumption without causing wear problems, and also to: - Extend grease lubrication cycles - Avoid grease spillage and residue - Reduce the number of bearing failures » The trial was designed so the bearings would be greased one time with QUAKERTEK™ VERKOMAX EP-12, calcium sulfonate complex grease, and then checked when 10.000tn, 15.000tn, and 20.000tn of steel was rolled. The chart and pictures below shows how the bearings looked at the evaluation points. At each point the grease layer becomes thinner, but grease still remains in the space between the rolling elements BEARINGS TARGET (tn) REACHED (tn) 10.000 9.007 15.000 15.928 20.000 22.078 03.16 - V003 - EN
