This ball bearing supports the clutch shaft within the transmission housing, maintaining correct axial and radial alignment of the rotating assembly. It carries the load from the clutch engagement and disengagement cycles, allowing the shaft to spin freely without excessive friction. A worn bearing produces a rumbling or growling noise during clutch operation and can lead to shaft misalignment, which accelerates wear on the clutch disc and release mechanism. The bearing is sealed on both sides to retain lubricant and exclude contaminants, matching the original assembly's geometry so it seats correctly in the housing bore without additional shimming.
