It supports the rotating shafts inside the PTO, allowing smooth power transfer from the transmission to auxiliary equipment like hydraulic pumps or winches. You typically replace this bearing during a PTO rebuild or when you notice noise, excessive play, or metal in the oil, as a worn bearing can quickly damage gears and housings. The assembly combines both the inner cone (1.18" bore) and the outer cup (approximately 2.5" outer diameter) into one replacement part.
