Product Description

     Double-direction angular contact thrust ball bearings with two dimension series, 2344 and 2347. 2344 series are fit for the small end of taper bore of double row cylindrical roller bearings,and 2347 series for the large end.

     As for ZYS double-direction angular contact thrust ball bearings, a cirumferential oil groove and three symmetric lubrication holes are set up in the middle of outer ring. Lubricants are led into the space between the double row rolling elements and cage assemblies, then lubrication through the rotation of bearing will be realized.

    ZYS double-direction angular contact thrust ball bearings have such advantages as high accuracy, high rigidity, low temperature rise, high speed and convenient fixing and removing.
