Not all brands are fast repairable as just presssing a new hub in, will depend on the brand. If you press a new hub into a prop that's factory vulcanized will spun again shortly, worst if needing constant wot applications at high load. Works ok if runing slow, but that's is another story.
It's same vulcanizing method used on engine supports, when middle hub breaks, you send it back to have it vulcanized or you buy a new one.
