Mobil Centaur XHP™ 461 water resistant grease success story

Cut grease consumption by

Water resistant mill bearing grease



A customer's rough mill bearings were working under very difficult conditions because of exposure to excessive amounts of water, in addition to high loads and temperature. During periodic maintenance, observations noted that the current lithium complex soap grease was no longer present on the roll necks due to high water exposure. The site decided to replace the grease with another lithium-complex soap grease including solid lubricants. However, the conversion to lithium-complex with solid additives caused consumption to dramatically increase.


After discussions between Mobil engineers and the company’s mechanical engineering team, it was decided to use the next-generation Mobil Centaur XHP™ 461 grease, which has unique water resistance and high load bearing capacity.


After switching to Mobil Centaur XHP 461 grease and completing a feed rate reduction study, the customer was able to reduce consumption in a Rough Mill stand from 1280 kg to 307 kg — a 76 percent reduction in grease consumption. Based upon customer costs, this accounted for $3,650 in annual cost savings on grease in 1 mill stand. After trial, the mill stand was fully disassembled; Mobil Centaur XHP 461 grease was still in place despite high H20.
