Radial ball bearings comprise an inner and outer ring encasing one or more rows of balls, designed to accommodate both radial loads and axial loads from two directions. They are known for their high performance and versatility, and are therefore the most widely used type of rolling element bearing in the world. Radial ball bearings is a large category encompassing a multitude of ball bearing types, including deep groove bearings, angular contact bearings
, four-point contact bearings, double-row angular contact bearings, self-aligning bearings
, and more. Each of these bearing designs has a unique design specialized for different types of applications, all concerning radial loads, or loads perpendicular to the direction of the shaft axis. They are limited in resistance to shock loads, and are not recommended for applications where heavy shock loads are present. Deep groove ball bearings specialize in high-speed applications and are extremely versatile, being the most popular type of radial ball bearing. Angular contact bearings are designed with a specific contact angle, allowing for different levels of load capacity and applications. Four-point contact ball bearings have a divided inner ring, and can be used in a two-point contact state, eliminating the need for a second bearing. Double-row angular contact bearings have a similar function to single-row angular contact bearings, but are more suitable for higher load capacities, at the expense of speed capabilities. Self-aligning bearings have cylindrical raceways, allowing them to accommodate shaft or housing misalignment. Radial ball bearings are available in a multitude of materials, including bronze, steel, thermoplastics, or ceramic and ceramic hybrids. MRO Supply carries a wide variety of radial ball bearings of different designs, sizes, materials, and manufacturers, to suit your application. Ask our experts about which radial ball bearing you need.
