摘要： A seal lip having: a cylindrical seal surface in close contact with an outer peripheral surface of an inner race with outer side and inner side surfaces standing upright respectively from an outer end and an inner end of the seal surface and reaching a lip supporting portion of a seal member, and protruding on an inner peripheral surface of the lip supporting portion. The outer side surface is a perpendicular surface standing upright from the outer end of the seal surface in a direction perpendicular to a generating line of the outer peripheral surface of the inner race. The inner side surface includes: a perpendicular surface standing upright from the inner end of the seal surface in parallel with the outer side surface; and a conical surface inclined toward the outer side surface extending outward in a radial direction from an outer peripheral end of the perpendicular surface.

摘要： In a rolling bearing with seal, an annular lip supporting portion having a larger thickness than that of a seal lip is formed on an inner periphery side of a seal member; the seal lip protruding on an inner peripheral surface of the lip supporting portion has: a cylindrical seal surface being in close contact with an outer peripheral surface of an inner race; and an inner side surface at least part of which in a region from an inner end of the seal surface to reach the lip supporting portion stands upright from the inner end of the seal surface in a direction perpendicular to a generating line of the outer peripheral surface of the inner race; and a width of the seal surface in an axial direction is set to be larger than a height of the seal lip in a radial direction. Accordingly, it is possible to provide a rolling bearing with seal with a simple structure, which is capable of maintaining a normal seal pressure against an inner race of a seal lip even when large negative pressure or positive pressure acts on the seal lip, thus preventing leakage of grease inside the bearing.
摘要翻译：在具有密封件的滚动轴承中，在密封构件的内周侧形成有比密封唇的厚度大的环状的唇部支撑部，在唇支撑部的内周面上突出的密封唇具有：与内圈的外周面紧密接触的圆筒状的密封面; 并且在从密封面的内端到达唇支撑部的区域的至少一部分的内侧表面沿着与外周面的发生线垂直的方向从密封面的内端立起的内在种族; 并且沿轴向方向的密封表面的宽度被设定为大于密封唇缘在径向上的高度。因此，可以提供具有简单结构的密封的滚动轴承，即使在密封唇上施加大的负压或正压力时，也能够保持对密封唇的内圈的正常的密封压力，从而防止润滑脂在轴承内泄漏。
