摘要： A deep groove ball bearing includes an outer ring, an inner ring, a plurality of balls, and a seal member. An axial cross-sectional width is smaller than a radial cross-sectional height, a thickness of the inner ring is greater than a thickness of the outer ring, and a pitch diameter of the ball is larger than a median diameter between an inner diameter of the inner ring and an outer diameter of the outer ring A radial dimension between an outer diameter of a shoulder portion of the inner ring and an inner diameter of the seal member is greater than the thickness of the outer ring. As a result, width and weight can be reduced, a load capacity can be secured, grease leakage can be prevented, and a service lifespan can be extended.

摘要： A sealing device is disposed between an inner member and an outer member that rotate relative to each other to seal a gap between the inner member and the outer member of the sealing device, and includes a first sealing member including a cylindrical part to be mounted to the outer member, and an annular part that extends radially inward from the cylindrical part toward the inner member; and a second sealing member including a sleeve to be mounted to the inner member, and a flange that extends radially outward from the sleeve, the flange facing the annular part of the first sealing member. The first sealing member includes at least three axial lips made from an elastic material that extends from the annular part toward the flange of the second sealing member. An axial lip disposed radially outer side has an interference that is greater than that of an axial lip disposed radially inner side.

摘要： An exhaust turbocharger including a modular bearing designed for bearing a shaft and arranged between a compressor and a turbine is provided herein. The bearing has a bearing housing having a receptacle chamber, wherein a bearing assembly module can be or is installed in the receptacle chamber and can be non-destructively removed. The receptacle chamber is sized such that either a bearing assembly module having a rolling bearing or a bearing assembly module having a slide bearing can be installed. The receptacle chamber has an interface, designed to contact the bearing flange of a bearing assembly module inserted into the receptacle chamber. The interface is designed to connect an oil gallery passing through the bearing housing to one or more oil galleries passing through a bearing flange of the bearing assembly module.
