Abstract | PROBLEM TO BE SOLVED: To provide a rolling bearing device reducing a torque loss while securing sealing performance. SOLUTION: The rolling bearing device includes an inner ring 10, and outer ring 15, a plurality of rolling elements 21 rollably disposed between the inner and outer rings 10, 15, and a sealing member 30 sealing an annular space between the inner and outer rings 10, 15. The sealing member 30 includes a first seal member 31 pressed into the inner ring 10, and a second seal member 41 pressed into the outer ring 15. The first seal member 31 is formed with an outer diameter side bent part 33 bent in an outer diameter direction toward the inner peripheral surface of the outer ring 15. The second seal member 41 is formed with an inner diameter side bent part 43 bent in an inner diameter direction toward the outer peripheral surface of the inner ring 10 and constituting a sealing annular space 50 in cooperation with the outer diameter side bent part 33. A lubricating member 51 with lubricity for sealing a sealing annular space 50 is disposed in the sealing annular space 50. COPYRIGHT: (C)2011,JPO&INPIT |
