introduction：playINAYes bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]An important factor in whether it works properly。Select the appropriate bearing clearance，The load can be distributed reasonably among the rolling elements；Energy limiting axis（Or shell）The axial and radial displacement of the axis to ensure the rotation accuracy of the shaft；Import bearing[Imported bearing:Simply say imported bearing generation

introduction：Engine oil is the most critical factor to ensure the normal operation of the engine and delay the life of the engine。Its lubrication、cooling、The three main effects of cleaning are to solve the problem of heat generated during engine operation、Wear problems between components、A powerful weapon for problems such as metal particles。 So in the use of engine oil can not be sloppy，Dont pay a big price because you dont want to spend a little money。 It is understood，Engine oil is divided into gasoline engine oil according to the fuel used by the vehicle、Diesel engine oil
