摘要： A bearing device equipped with a resin-made pulley has, at one axial end portion of an outer ring, cutout portions which are formed so as to be opened on their outward side of the axial direction and spaced from one another at a specified interval in a circumferential direction of the outer ring. Each cutout portion has a rectangular-shaped sloped surface which is sloped radially outward of the outer ring along an axial direction from an opening-side end to the center of the outer ring so as to adjoin the cylindrical surface portion on the axially opposite side to the opening. Each cutout portion further has side faces which are generally parallel to a vertical bisector plane of the sloped surface containing a center axis of the outer ring on circumferential both sides of the sloped surface in a cross section perpendicular to the center axis of the outer ring.

摘要： There is provided a bearing sealing device capable of substantially completely preventing a leak of grease. A taper end portion of an axial extension of the bearing sealing device has an opposite surface and a rake face that forms a specified rake angle with the opposite surface. The opposite surface forms a narrow passage between the opposite surface and an outer peripheral surface of an inner ring. The narrow passage allows air to pass easily, but it allows grease to hardly pass therethrough. Further, the axial extension includes part of a core metal that extends axially and has its foremost end located axially inside an axial outermost end of the outer peripheral surface of the inner ring. Grease moving axially outwardly on the outer peripheral surface is moved along the rake face of the taper end portion and then guided along a cover portion of the bearing sealing device to an outer ring. The part of the core metal prevents the axial extension from being bent radially outwardly by a centrifugal force.

摘要： A seal assembly interposed annularly between the inner and outer rings of a bearing assembly to seal an annular cavity formed between the inner and outer rings of the bearing assembly, the seal assembly having an annular seal member fitted onto the inner peripheral surface of the outer ring, a first annular seal lip, and a second annular seal lip, the first annular seal lip being in elastic-contact with the sidewall of an annular groove formed in the inner peripheral surface of the inner ring. The first annular seal lip has a radial length and an axial thickness satisfying a ratio (A/B) of the radial length (A) to the axial thickness (B), the ratio (A/B) being in the range of not less than 4.5 and not more than 7.0 to obtain a moderate rigidity capable of following the relative movement of the inner and outer rings. Communicating grooves are formed in the lower end portion of the first annular seal lip for communicating between the inside and outside of the bearing assembly, in order to prevent an increase in pressure within the bearing assembly because of a rise in temperature within the bearing assembly.

摘要： In a pulley assembly, an annular joint member made of a high polymer material is disposed between an outer ring of a bearing and a light metal pulley. The joint member has a coefficient of thermal expansion larger than that of the pulley. The outer ring has a coefficient of thermal expansion smaller than that of the pulley. The pulley has an annular boss, an annular rim, and a plurality of spokes which have side faces each consisting of a surface parallel to an axial direction of the pulley. Front faces of the spokes are positioned on one identical imaginary surface of revolution, and rear faces of the spokes are also positioned on one identical imaginary surface of revolution.
