A more premium bearing is the double ball bearing. In addition to handling and mounting advantages, these double ball bearings may also have some financial advantages; but, in some circumstances, they might not have as much performance and design freedom. These bearings can support far heavier loads than single row bearings since they are compact, sturdy, and have a considerable radial capacity as well as the option for a modest thrust capacity in either direction. In some applications, the use of these bearings may offer lower performance and lessen the degree of design flexibility.
