Observation of Grease Fluidity in a Ball Bearing Using Neutron Imaging Technology

open access: yesTribology Online, 2021
The grease fluidity and migration inside a ball bearing has been visualized non-destructively by using a neutron imaging technology. It has been clarified that a lithium (Li) complex grease with lower torque lubricates in the channeling state and that a ...
