A bearing is a part that reduces the friction that builds up between moving parts. The proper type of grease must be considered to provide a long bearing life. This study aims to analyze the differences between Mobilith SHC 100 and Gulf Crown EP 2 greases. This study employed a laboratory test method conducted at PT Petrolab Services with the test parameters of base oil viscosity, dropping point, and worked penetration at 250C. Further, as the supporting data, a comparison of the bearing repairs was executed at Balai Yasa Manggarai using Gulf Crown EP 2 grease in 2018 and Mobilith SHC 100 in 2021. The study results suggested that Mobilith SHC 100 grease offered more advantages in maintaining its characteristic stability compared to Gulf Crown EP 2. Moreover, the bearing repairs at Balai Yasa Manggarai in 2018 and 2021 indicated that Mobilith SHC 100 had fewer bearing repairs and higher maximum mileage than Gulf Crown EP 2.
