NSKBearing rear designation： （1）Internal structure A——Internal design differs from the standard bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]。 A——Angular contact ball bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]，The contact Angle is30The degree of。 A5——Angular contact ball shaft
If a certain way occurs a deeper compressive stress layer，For corrosion stress。Can offset the workpiece bearing Tensile stress，Greatly reduce corrosion fatigue hazards，Try to change the induction heat，When the sensor is in contact with the workpiece，Its resistance to the ground drops rapidly，The resistance can then plummet as an electrical signal，The induction heating power supply is immediately cut off through the transistor switching circuit，At the same time, alarm signal is issued，After troubleshooting，Re-power to restore the workpiece induction heating。Imported bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing
Speaking of rails，I believe that the accuracy of the guide rail is the choice standard of our friends，Yes.，The accuracy of our guide rail is a very important assessment standard，High precision guide，To make the machine work better。But usually，We must learn to maintain the accuracy of the guide rail。
Under certain operating conditions，Deep groove ball bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]It can obtain a longer life than the traditional calculation，Especially in the case of light loads。These special operating conditions are，When rolling surface(Tracks and rolling parts)A lubricating film effectively separates and limits the surface damage that contaminants can cause。In fact，Under ideal conditions
1．bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]Life span Under a certain load，Rolling bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]Run until fatigue pitting occurs on either roll or ring raceway，The total number of revolutions of the two rings relative to each other（Number of turns）Or the number of hours worked，
rollFAGBearings in the process of use due to their own quality and external conditions，Its carrying capacity，The rotation accuracy and anti-friction energy performance will change，whenFAGWhen the performance index of the bearing is lower than the use requirements and can not work normally，Be known asFAGBearing damaged or invalid，FAGbearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]In case of damage, etc

When we are onKOYOBearings are inspected before，Should be cleaned firstKOYOBearing surface，Then disassembleKOYOParts around the bearing。Oil seals are fragile parts，Therefore, extra care is required during inspection and disassembly，Do not apply excessive force，So as not to cause damage to parts。Then check it carefullyKOYObearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]The oil seal and its circumference
bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]In the course of its use, it shows strong regularity，And repeatability is very good。Normal high quality angular contact ball bearings[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]At the beginning of use，Vibration
SKFThe function of the bearing fit is to makeSKFThe stationary ring and rotating ring of the bearing are respectively the stationary part of the installation part(usuallySKFBearing block)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。Axial sumSKFbearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]
