Generally,lubrication can be performed by oil grease.
Oil
(1)Recommended for extremely high operation speeds
(2)Good for assembly where the bearing is located in the same houseing as other oil lubricated components
(3)Suitable for extremely high operating temperatures
(4)Good when a central oil system is used for auxiliary machine parts
(5)Good when bearing torque requirement is a critical parameter
Grease
(1)Grease is recommended for bearings without an elaborate housing
(2)Grease gives long service operation without renewal or inspection
(3)Grease performs a more effcient exclusion of dirt
