Single-row Angular Contact ball bearings can sustain radial, axial or composite loads, however, any axial load must be in one direction.
单列角接触球轴承可承受径向，轴向或复合负荷，不过，任何轴向负载必须在一个方向。

Because of oscillation of the blower load the variation of angular velocity of the blower rotor and beats in lower frequency are inevitable.
与风机负荷的波动相关，风机转子的角速度变化及相伴的低频拍振是不可避免的。

On the single row angular contact bearings, radial load rating of bearing rings relative to each other purely radial displacement of the load of the radial component.
