| 游隙 Clearance |
径向游隙按ISO5753标准分为五组，无负荷的径向游隙值见表5
In accloradance with the standard of IOS5735.The radial Clearance Can be divide into five groups .Radial
Clearance Value without load See Table5
深沟球轴承加速度振动值（dB）见表6 Deep Groove Ball Vearing Acceelerating Balue(dB).see Table 6
深沟球轴承加速度振动值（um/s）见表7 Deep Groove Ball Vearing Acceelerating Balue(um/s).see Table 7

防锈 Rustresisting
J&P轴承在正常储存，保管的条件下，防锈期半年，保管期超过半年的，应在防锈期到期日前检查后再按规定进行复防，以保持轴承不生锈。
J&P Bearing normaally be put under the protected condition then it is to be stored amd preserved. The
rustresisnting periodis half a year If there is half a year over the preservation preservation period .At the time before the espiring date of rustresisting yuo have to check is over the then according to the stipuation to be rustresisted again so as to keep the bearing not rusty. |
