Abstract

PURPOSE: To prevent leakage of grease by a method wherein replacement of the grease is effected by withdrawing the deteriorated grease while sucking the new grease thereinto.
CONSTITUTION: A vessel containing new grease 11 is connected to a grease pouring port 12 of a bearing 1 while a extracting pump 14 is connected to a discharging port 4. A vacuum resisting packing 13 and a hydroextracting fringer 8 are provided at the bearing portion. The deteriorated grease drawn in by the extracting pump 14 is discharged to outside through the discharging port 4.
