Ball bearings are often optimized for radial contact: this means that they will be very useful if the force you want to bring into contact with the bearing is perpendicular to its axis of rotation. However, double row ball bearings are optimized for angular contact. Additionally, if you want to use a ball bearing for an axial load, it should be noted that this device only supports moderate axial loads. However, this flaw can be avoided by using a double-row ball bearing construction. As well as being low-cost, ball bearings are also the most compact, making them the most widely used type of bearing.

We strongly recommend the use of ball bearings for small bearings that operate at high speeds.
