<p><P>PROBLEM TO BE SOLVED: To provide a sealed rolling bearing, having excellent grease leakage preventive effect while achieving reduction of torque and high dust resistance. <P>SOLUTION: In this sealed rolling bearing 1, a plurality of balls 4 interposed between inner and outer rings 2, 3 are held by a cage 5, and bearing space is sealed with a seal 6 fitted to the outer ring 3. When a ball diameter, which is a diameter of the ball 4, is represented by Da, a radial clearance gapδbetween the outside diameter surface of the inner ring 2 and the inside diameter surface of the cage 5 is 0.09 Da or more. The radial clearance gapδis preferably 0.36 Da or less. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
