Abstract:
An inner ring includes: a pair of shoulder outer peripheral surfaces on first and second axial sides of a raceway surface of the inner ring in contact with balls; seal grooves disposed in first and second axial ends of the inner ring and defining labyrinth clearances with lips; and edges disposed on the first and second axial sides. Each of the edges is configured to cause grease flowing along an associated one of the shoulder outer peripheral surfaces to leave the shoulder outer peripheral surface in the direction of an extension thereof. Each of the lips includes a lip oblique surface functioning as a guide surface to guide the grease that has left the edge not to a radially inner region of the bearing but to a radially outer region of the bearing.

Claim (Index 1):
A rolling bearing comprising:\n an inner ring; an outer ring; a plurality of balls each in contact with a raceway surface of the inner ring and a raceway surface of the outer ring at a contact angle; an annular cage retaining the balls; and seals attached to portions of the outer ring on first and second axial sides, each seal including a lip defining a labyrinth clearance with the inner ring, each lip being configured to prevent grease leakage, wherein:\n the outer ring includes\n a first outer shoulder respectively disposed on the first axial side of the outer ring raceway and a second shoulder respectively disposed on the second side of outer ring raceway, and \n the bore diameter of the second shoulder is larger than the bore diameter of the first shoulder, \n \n the inner ring includes\n a pair of shoulder outer peripheral surfaces on the first and second axial sides of the raceway surface of the inner ring in contact with the balls, \n seal grooves in first and second axial ends of the inner ring, each seal groove defining the labyrinth clearance with an associated one of the lips, and \n edges on the first and second axial sides, each edge being configured to cause grease flowing along an associated one of the shoulder outer peripheral surfaces to leave the shoulder outer peripheral surface in the direction of an extension of the shoulder outer peripheral surface, \n \n the lips each include a guide surface to guide the grease that has left the edge not to a radially inner region of the rolling bearing but to a radially outer region of the rolling bearing, and \n an inner peripheral surface of the cage does not extend in an axial direction past the opening of the labyrinth clearance on the second axial side, the opening of the labyrinth clearance on the second axial side being formed between the edge of outer peripheral surface on the second axial side and the guide surface of lip on the second axial side.
