The Berkeley S15604 roller bearing is a replacement bearing with a 1.9685-inch inside diameter and AFBMA 50RK32 designation. It serves as an individual service component in Berkeley pump assemblies that specify S15604.
Use the complete pump model and bill-of-material number to select the bearing. A pump family name alone is not enough: different configurations can use different bearing arrangements, even when the external pump dimensions appear similar.
Replacing the correct bearing allows worn shaft-support components to be serviced while retaining the rest of a suitable pump assembly. Inspect the shaft and bearing seat during service so a new bearing is not installed over damage that also needs repair.
