檢修裝配下的NSK軸承時，首先記載軸承外觀，確認光滑劑的殘存量，取樣后，清洗軸承。
When inspecting and repairing NSK bearings under assembly, first record the appearance of the bearings, confirm the residual amount of smoothing agent, after sampling, clean the bearings.
清洗劑廣泛運用汽油、煤油。
Cleaning agents are widely used in gasoline and kerosene.
拆下來的軸承的清洗，分粗洗和精洗，在容器內先放上金屬網，使軸承不間接接觸容器內的臟物。
The bearings removed are cleaned, roughly cleaned and cleaned. The metal mesh is placed in the container first, so that the bearings do not indirectly contact the dirt in the container.
粗洗時，假如軸承帶著臟物旋轉，會傷害NSK軸承滾動面，應當加以注重。
In rough washing, if the bearing rotates with the dirt, it will damage the NSK bearing rolling surface.
在粗洗油中，運用刷子進來光滑脂、粘著物，基礎干凈后，轉入精洗。
In crude oil wash, use brush to come in smooth grease, adhesive, clean foundation, turn to fine wash.
精洗，是將軸承在清洗油中一邊旋轉，一邊細心地清洗。
Fine cleaning is to wash the bearings while cleaning the oil while cleaning them carefully.
另外，清洗油也要常常改換維持干凈。
In addition, cleaning oil should also be changed to keep clean.
