Radial bearings are designed to support loads that act perpendicular to the axis of rotation. These bearings are commonly used in applications where the primary load is radial, such as in rotating shafts or wheels. Examples include deep groove ball bearings, which have a contact angle ranging from 0° to 45°. This makes them ideal for handling both radial and light axial loads. On the other hand, axial bearings, also known as thrust bearings, are specifically engineered to handle loads that act parallel to the axis of rotation. They are typically used in situations where the main force is axial, such as in vertical shafts or rotating platforms. The contact angle of these bearings usually ranges from 45° to 90°, allowing them to efficiently manage thrust forces. Understanding the difference between radial and axial bearings is essential for selecting the right type of bearing for a specific application. Choosing the correct bearing ensures optimal performance, reduces wear, and extends the lifespan of mechanical systems.
