Sealing device for bearing |
摘要 |
In a sealing device for a bearing, a sub-seal lip (94) is configured such that a slide contact surface is formed like an annular band. As the rotation speed of the bearing increases, the width of the slide contact surface is reduced by a centrifugal force. Thus, sliding friction can effectively be minimized. The torque of the bearing can be prevented from increasing at high-speed rotation. Even when the centrifugal force increases somewhat, only reduction in the width of the slide contact surface is caused. Thus, a slide-contacted state can be maintained. Consequently, the problem of floating-up of the sub-seal lip (94) from a slinger (10) is difficult to occur.
