R Series Inch Deep Groove Ball Bearings
Deep groove ball bearings are a type of rolling element bearing that can handle both radial and axial loads. They have deep raceway grooves on the inner and outer rings, allowing them to accommodate high radial and axial loads in both directions. These bearings are commonly used in various applications such as electric motors, automotive components, and machinery.
The R Series refers to a specific series of deep groove ball bearings that are designed in accordance with inch measurements. This series is widely used in the United States and other countries that follow the imperial measurement system. The R Series typically includes bearings with inner diameters ranging from 0.1875 inches (4.7625 mm) to 1.5 inches (38.1 mm).
