Greased lubrication is directly put the grease between the movement surfaces of bearings, but to the input of the rolling bearing raceway and sliding work surface grease, you must follow the following five principles:
(1) grease must be run through the bearing surface and internal gap  of KOYO bearings, so as to make the grease to fully play a role in lubrication.
(2) Should be retained on the working surface of the rolling bearing a certain amount of grease, and persist for some time, but also to prevent excessive loss due to grease.
(3) The input of the grease and exhaust flow and sealing requirements consistent, which is conducive to the invasion of the discharge of contaminants.
(4) First to ensure good lubrication to minimize the amount of grease.
(5) At the end of the grease flow to open the exit hole, so that the new supplement of grease  can squeeze out the old grease to ensure good lubrication .
