ABSTRACT:
It is intended that the rotation resistance is decreased while the durability and seal performance are kept in the rolling bearing unit with seal ring.The most thin wall-thickness portion30is provided in the vicinity of the base end of the seal lip22aprojecting laterally in sliding contact with the mating surface. The most thick wall thickness portion31is provided adjacent to the most thin wall thickness portion30on the tip end side. The thickness is gradually decreased from the most thick wall thickness portion31to the tip end. Further, the ratios of thickness in the respective portions22aare properly controlled.
