introduction： SKFImported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]The function of matching is to make the bearing stationary ring and rotating ring respectively with the stationary part of the installation part(Usually a bearing seat)And rotating part(Usually an axis)Solidify together，Thus, the basic tasks of transferring the load in the rotating state and defining the position of the moving system relative to the stationary system are realized。On the shaft and in the bearing housing，Rolling bearings are required in radial direction、Axial and tangential

introduction：one．Grease storage There are many varieties and grades of greases、Different performance，Fat spoils more easily than oil，And it is not easy to deal with impurities mixed in the fat，Therefore, it is of great significance to strengthen the quality management of grease storage。 1、Mass variation in grease storage The quality of grease after long-term storage changes in the following aspects： 1) Change color； 2) Mixed lime sand、Dust and other mechanical impurities； 3) Mix in water or absorb water： 4) Lubricating oil precipitates after long-term storage，agglomerate，Oil soap separation occurred，Acid-forming substance，Corrosion unqualified, etc。 2、in-storage

introduction：Motor power，It should be selected according to the power required by the production machinery，Try to keep the motor running at its rated load。The following two points should be noted when choosing： (1)If the motor power is chosen too small，Will appear“Little horse and big cart”phenomenon，Cause motor overload for a long time，The insulation is damaged by heat，Even the motor was burned。 (2)If the motor power is selected too large，Will appear“horseman”phenomenon，Its output mechanical power can not be fully utilized，The power factor and efficiency are not high(See table)，Not only bad for users and the grid。It also wastes electricity
