Why inner radius of the housing washer and shaft washer is different in thrust bearing? I checked on SKF's website dimensions of a thrust bearing. The inner radius of the housing washer is different than the shaft washer inner radius. Can any you tell why is that?

The race with a tighter inner diameter is meant to press onto a shaft and transmit the thrust load from the shaft into the bearing elements. The housing race has a looser bore and is meant to clear the shaft so it does not accept any thrust from the shaft, this race is typically a press into your housing.
