ABSTRACT:
The present invention provides a bearing sealing method for sealing a bearing member which is interposed between a first member and a second member and allows relative rotation between the first member and the second member. The method includes the steps of keeping the bearing member under a sealed state by interposing a seal between the first member and second member; and releasing the bearing member from the sealed state by bending a first seal element of the seal outward only upon pressure increase in the sealed bearing member. The first seal element is normally in contact with one of the first member and the second member.
