  Double row angular contact ball bearing

The design of 3901-2RS 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.
