Situation
Fujian Meiling Cement Co. Ltd. operates two 2500 T/D production lines. Lubricated with an ISO 320 viscosity grade conventional mineral oil, the bearings on one of the lines were experiencing failures due to heavy loads and high operating temperatures. In an effort to improve equipment reliability, operators from Fujian Meiling Cement Co. Ltd. approached ExxonMobil to identify a lubricant solution capable of extending oil drain intervals, and reducing failure incidents and related operational shutdowns.

Recommendation
After conducting a root cause analysis, ExxonMobil engineers recommended the company switch to Mobil SHC™ 632 synthetic circulating oil in its production line bearings. The high viscosity index of Mobil SHC 632 and its synthetic formulation provides strong resistance to mechanical shear to protect equipment while extending the oil life. In addition, engineers recommended the company implement routine Mobil ServSM Lubricant Analysis to monitor equipment and oil condition.

Result
After transitioning to Mobil SHC 632 synthetic circulating oil, the company was able to improve the performance of its production line by extending oil drain intervals, reducing costs associated with bearing replacements, improving equipment productivity and decreasing labor costs. Fujian Meiling Cement Co. Ltd. reports that switching to Mobil SHC 632 synthetic circulating oil has generated company-estimated annual savings of US $97,000.
