摘要：PROBLEM TO BE SOLVED: To provide a rolling bearing given with prevention measures for leakage of a lubricant. SOLUTION: The rolling bearing comprises race rings (outer ring 2, inner ring 4) arranged opposite for relative rotation, and a seal structure (pack seal 10P) fitted between the race rings in slide contact with them for sealing a bearing inside comparted between the race rings from the bearing outside, wherein the seal structure is fitted between the race rings with pressure of the bearing inside kept equal to or lower than the atmospheric pressure. In this case, in the state that the seal structure is fitted between the race rings, air corresponding to the volume of the seal structure is compressed and added to the bearing inside and therefore the pressure of the bearing inside is set at almost the same level with the atmospheric pressure.
