Double-direction angular contact thrust ball bearings performanceDouble direction thrust ball bearings refer to angular contact thrust ball bearings,Website:://.zys-bearing.com, It is composed of two shaft washers,a housing washer ,a spacer,two rolling elements and cage components.Grinding the thickness of spacer can adjust the clearance and preloaded of bearing.The contact angle is 60 ,which have two dimension series, 2344 and 2347. 2344 series are fit for the small end of taper hole of double row cylindrical roller bearings, and 2347 series for the large end. As for ZYS  double direction angular contact thrust ball bearing, a circumferential oil groove and three symmetric lubrication holes are set up in the middle of outer ring. Lubricant is lead into the space between the two-row rolling elements and cage assemblies,the lubrication through the rotation of bearing will be realized.ZYS angular contact thrust  bearings have such advantages as high accuracy,high rigidity, low temperature rise, high speed and convenient fixing and removing.
