摘要： PROBLEM TO BE SOLVED: To provide a rolling bearing with seal configured to increase seal pressure against an inner race of a seal lip as a negative pressure increases when the negative load acts on the outside of a seal lip, and to reliably prevent leakage of grease in a bearing.SOLUTION: A rolling bearing with seal includes an annular lip support part 42 formed on an inner peripheral side of a seal member 34 to be thicker than a seal lip 43. The seal lip 43 protruded from the inner peripheral surface of the lip support part 42 has a trapezoidal cross section including: a cylindrical seal surface 43a in close contact with an outer peripheral surface of an inner ring 30; an outside surface 43c standing from an outer end of the seal surface 43a to reach the lip support part 42; and a conical inside surface 43b which inclines toward the outside surface 43c while extending radially outward from an inner end of the seal surface 43a, to reach the lip support part 42.

摘要： PROBLEM TO BE SOLVED: To provide a rolling bearing with seal configured to increase seal pressure against an inner race of a seal lip as a negative pressure increases when the negative load acts on the outside of a seal lip, and to prevent changes in seal area even if a seal surface of the seal lip is worn.SOLUTION: On an inner peripheral surface of a lip support part 42 of a seal member 34, a protruding seal lip 43 is formed which includes a cylindrical seal surface 43a in close contact with an outer peripheral surface of an inner ring 30, and an outside surface 43c and an inside surface 43b which are raised from an outer end and an inner end to reach the lip support part 42. The outside surface 43c is a vertical surface standing upright in a direction orthogonal to a bus line of the outer peripheral surface of the inner ring 30 from the outer end of the seal surface 43a. The inside surface 43b is formed of a vertical surface 43b1 standing upright in parallel to the outside surface 43c from the inner end of the seal surface 43a, and a conical surface 43b2 inclined toward the outside surface 43c extending radially outward from the outer peripheral end of the vertical surface.

摘要： PROBLEM TO BE SOLVED: To provide a ball bearing for flow control valve provided in an intake and exhaust systems of an engine, in which sealing ability is enhanced for both positive and negative pressures so that no separate sealing means is required.SOLUTION: A seal member 6 is provided on one end of a bearing 1, and a seal member 7 on the other end of the bearing 1. The seal member 6, including a metal core 10 and an elastic body 11, is fixed to an outer ring 3 so that an outside lip part 13A and an inside lip part 13B contact an outer peripheral surface 2A of an inner ring 2. When a positive pressure acts on the outside of the seal member 6, the pressure presses the outside lip part 13A against the outer peripheral surface 2A of the inner ring 2, such that air tightness of the seal member 6 is maintained. When a negative pressure acts on the outside of the seal member 6, a differential pressure between the outside and inside of the seal member 6 presses the inside lip part 13B against the outer peripheral surface 2A of the inner ring 2, such that air tightness of the seal member 6 is maintained. Thus, sealing ability can be enhanced for positive and negative pressures, which allows no separate sealing means to be required.

摘要： PROBLEM TO BE SOLVED: To provide a rolling bearing having a sealing function in which sealing ability is enhanced for positive and negative pressures and sufficient air tightness for pressure fluctuations is maintained.SOLUTION: A seal member 6 is provided on both ends of a bearing 1. The seal member 6, including a metal core 10 and an elastic body 11, is fixed to an outer ring 3 so that an outside lip part 13A and an inside lip part 13B contact an outer peripheral surface 2A of an inner ring 2. When a positive pressure acts on the outside of the seal member 6, the outside lip part 13A is pressed against the outer peripheral surface 2A, such that air tightness of the seal member 6 is maintained. When a negative pressure acts on the outside of the seal member 6, differential pressure between the inside and outside of the seal member 6 presses the inside lip part 13B against the outer peripheral surface 2A, such that air tightness of the seal member 6 is maintained. Thus, sealing ability can be enhanced for positive and negative pressures and sufficient air tightness for pressure fluctuations can be maintained.
摘要翻译：要解决的问题：提供一种具有密封功能的滚动轴承，其中正负压力的密封能力得到提高，并且保持了足够的压力波动的气密性。解决方案：密封件6设置在轴承1的两端包括金属芯10和弹性体11的密封构件6固定在外圈3上，使得外唇部13A和内唇部13B与内圈2的外周面2A接触。当正压力作用在密封构件6的外侧，外唇部13A被压靠在外周面2A上，从而保持密封构件6的气密性。当负压作用在密封构件6的外部时，密封构件6的内部和外部之间的压差将内唇部13B压靠在外周面2A上，从而保持密封构件6的气密性。因此，可以提高正压和负压的密封能力，并且可以保持用于压力波动的足够的气密性。

摘要： PROBLEM TO BE SOLVED: To avoid the situation of damaging a ball, and to improve a yield when fitting the ball in a pocket of a bearing retainer in an assembling process of a ball bearing. SOLUTION: A shape (such as a diameter and the depth) of a cylindrical cutout part 7 of the bearing retainer 6 is changed to control a degree of freedom of elastic deformation of a claw 3. Pressure required for push-opening the claw 3 is optimized, and when fitting the ball 11 in the pocket 2, the situation of damaging the ball 11 is avoided.
