Mobilith SHC™ 220 synthetic grease helps eliminate cooler fan bearing failures for major cost savings*

Cooler fan bearings

Charlevoix, Michigan, United States

Situation
During an ExxonMobil “Fundamentals of Grease Lubrication” training class, Michigan-based St. Mary’s Cement indicated they were experiencing two cooler fan bearing failures per year. To address these bearing failures, the company asked ExxonMobil to identify a lubricant solution capable of improving cooler fan reliability.

Recommendation
ExxonMobil engineers recommended switching to Mobilith SHC™ 220 extreme pressure grease. Formulated with synthetic-based fluids and a high-quality lithium complex thickener, Mobilith SHC 220 is designed to provide superior wear performance and protection from rust and corrosion compared to conventional greases. Additionally, ExxonMobil engineers recommended the company regrease the bearings with one gram every two weeks to avoid overgreasing, which could cause the bearing to overheat.

Result
After transitioning to Mobilith SHC 220 extreme pressure grease, St. Mary’s plant has not reported any bearing failures. As a result, the plant reduced equipment downtime as well as maintenance downtime by 64 hours. The company reports that Mobilith SHC 220 helped achieve significant savings by increasing up-time productivity and reducing maintenance costs and related personnel safety exposure.
