English: Deep groove ball bearings are particularly versatile. They are simple in design, non-separable, suitable for high and very high speeds and are robust in operation, requiring little maintenance. These bearings are the most common type and are used in a wide variety of applications. Not only are they capable of supporting radial loads but also moderate axial loads in either direction. Due to their low torque, they are suitable for applications where high speed and low power loss is required. They are easy to mount and suitable for many different configurations. They utilize an uninterrupted raceway that makes them optimal for radial loads .This design permits precision tolerance, even at high-speed operation.
