introduction：Oversize 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。]Different from small bearings，stand-alone、solo、Single piece machining，Extremely casual，It is easy to cause excessive dimensional tolerance or shape tolerance，For example, the amount of grinding after machining is small、Heat treatment deformation overshoot、Excessive contraction and uneven contraction、Carburizing pad injury and handling jam injury。If you work normally

introduction：Centrifugal separator for separating components in suspension by centrifugal filtration。There are many holes in the drum wall of the filter centrifuge，The inner surface of the drum is covered with filter media。The suspension added to the drum rotates with the drum to produce a huge centrifugal pressure，Under the action of pressure, the liquid in the suspension is thrown out through the filter medium and the holes in the drum wall，Solids are trapped on the surface of the filter medium，Thus, the separation of solid and liquid is realized。The centrifugal force generated by the suspension in the drum is thousands of times the force of gravity，The filtration process is enhanced，Speed up filtration，The filter slag with lower moisture content was obtained。Solid particles greater than0.01Millimeters of suspension can generally be filtered
