Deep-groove ball bearings are great for handling large loads and fast operating speeds. They can withstand a radial load and a limited axial (or thrust) load. In short, deep-groove ball bearings are a good option if there will be pressure applied to the bearing from both the side of a shaft (radial) and along the shaft (axial).
Deep groove ball bearings are available in both single row and double row designs. Single row ball bearings are the most popular of all rolling bearings. They are of simple design, non-separable and suitable for high-speed operation, and require little attention in service.
