Document Type and Number:
Japanese Patent JP6070202
Kind Code:
B2
Abstract:
The present invention provides a rolling bearing device and a rolling mill supporting roll using the same. The rolling bearing device is provided with sealing devices for sealing the opening of a first annular space between an inner ring component and an outer ring component. Each sealing device is provided with a metal core. Vent holes are disposed on the metal cores and communicate the first annular space and a second annular space, so as to release the pressure inside the first annular space to the second annular space. A second sealing lip is separated from an oil thrower if the pressure inside the first annular space exceeds a preset pressure, thereby enabling the pressure inside the first annular space to be released from the vent holes and the second annular ring to the outside space.
