Jinhai Pulp & Paper Co. Ltd.
Yangpu City, Hainan Province, China
Situation
Hainan Jinhai Pulp & Paper Co. Ltd. installed a pulp line in 2005 with a production capacity of 1,000,000 tons per year. Lubricated with a conventional mineral grease, the pulp line ventilator’s 472 bearings often experienced failure, causing unscheduled downtime associated with bearing replacement and repair. To improve equipment reliability, the company approached ExxonMobil for a lubricant solution capable of reducing bearing failure.
Recommendation
ExxonMobil engineers recommended switching to Mobilith SHC™ 220 synthetic grease based on the bearing operating conditions and Elastohydrodynamic (EHL) calculations. Designed for a wide variety of applications at extreme temperatures, Mobilith SHC 220 is formulated to provide excellent protection against wear, rust and corrosion, while maintaining operating viscosity at high and low temperatures.
Result
After transitioning to Mobilith SHC 220 synthetic grease, the company did not experience any bearing failures for two years, which helped reduce unscheduled downtime and increase production. Switching to Mobilith SHC 220 also helped improve bearing lubrication, which resulted in reduced labor costs and grease consumption.
