The design of double row angular contact ball bearing is basically the same as that of single row angular contact ball bearing, but only occupies less axial space. Double row angular contact ball bearing can bear radial load and axial load in two directions. It can limit the two-way axial displacement of shaft or shell, and the contact angle is 30 degrees. It can provide high rigidity bearing configuration and can withstand overturning torque. The double row angular contact ball bearing can bear the combined radial and axial load and torque load dominated by large radial load, which limits the axial displacement of the shaft in two aspects. It is mainly used in components that limit the bidirectional axial displacement of shaft and housing.
