Abstract
Official abstract text for this publication.
A seal equipped bearing assembly includes a plurality of rolling elements interposed between opposite raceway surfaces defined in respective raceway rings; a sealing member to seal a bearing space delimited between the raceway rings; and a gap formation facilitating element defined in a seal contact face in the other of the raceway rings, the gap formation facilitating element being a projection provided in a circumferential portion of the seal contact face in the raceway ring. The gap formation facilitating element is configured to render the sealing member to be a non-contact seal or to contact so that the contact pressure is approximately zero when the bearing assembly is in a rotating state. The sealing member is provided with a suction preventing device for preventing the sealing member from being sucked onto the other of the raceway rings.
