Double-direction angular contact thrust ball bearings

ZYS double direction thrust ball bearings refer to angular contact thrust ball bearings, 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, with 2347 series for the large end.
As for ZYS  double direction angular contact thrust ball bearing, one 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, thus lubrication will be realized through the rotation of bearing.
ZYS angular contact thrust  bearings have such advantages as high precision, good rigidity, low temperature rise, high speed and convenient fixing and removing.
