Double-Row Angular Contact Ball Bearings

The double-row angular contact ball bearing can carry combined axial and radial load which is dominated by the latter and moment load. It can limit bi-axial displacement of shaft or housing. Contact angle is 45 degrees. It is featured by better rigidity and higher axial load capacity with more steel ball loads, compared with single-row angular contact ball bearing.

Attention should be paid to installation of the double-row angular contact ball bearing. Although these bearings can bear bi-axial loads, if there is filling slot at one side, user should be careful not to let the main axial load go through the side of groove edge with filling slot.
