A bearing assembly can support a rotating shaft on a vehicle structure and can include a rolling element bearing that has an inner race configured to be press fit on the rotating shaft. An outer race can surround the inner race and be configured to be mounted on the vehicle structure. A plurality of rolling elements can be located between the inner race and the outer race. A retaining ring can be configured to be press fit on the rotating shaft and abut the inner race when the rolling element bearing and the retaining ring are press fit on the rotating shaft. The press fit between the retaining ring and the rotating shaft can contribute to the press fit between the inner race and the rotating shaft such that the retaining ring and the rolling element bearing together distribute a load input by the rotating shaft to the vehicle structure.

Seal assemblies for conveyor idler rolls are provided. In some embodiments, a plurality of subsets of seal components are selectively installable in the seal assembly. In some embodiments, one or more fins are included on a seal.

A tapered roller bearing may comprise an inner ring, an outer ring, and two rows of tapered rollers that are arranged in an O-arrangement between the inner ring and the outer ring. The inner ring may extend in an axial direction over a greater length than the outer ring, and a gap between the inner ring and the outer ring on at least one side of the tapered roller bearing may be sealed by a sealing assembly. The sealing assembly may comprise a main seal that is attached to the inner ring in a rotationally fixed manner, as well as a seal race ring that is attached to the outer ring in a rotationally fixed manner. The seal race ring may form a seal raceway for the main seal.

A bearing sealing device including a slinger member having a slinger cylindrical portion, a slinger flange portion, and a slinger outer diametrical cylindrical portion projecting from an outer diametrical side end portion of the slinger flange portion so as to overlap in diametrical direction with a step portion of the flange, and including a seal member having a seal member having a core member and a seal lip member. A seal outer diametrical cylindrical portion having a region facing an outer circumferential face of the slinger outer diametrical cylindrical portion and projecting so as to overlap in diametrical direction with the step portion is provided on an outer diametrical side end portion of the seal member. A projecting distal end portion of the seal outer diametrical cylindrical portion projects toward a side of the step portion further than a projecting distal end portion of the slinger outer diametrical cylindrical portion.

A bearing unit for agricultural use, the bearing unit comprising: a rolling bearing, a housing body for the rolling bearing, and a sealing device for preventing the entry into the rolling bearing of contaminants. The sealing device in turn having, at least on one side of the rolling bearing, a first sealing level defined by at least one sliding-contact sealing lip and a second sealing level arranged in series with the first sealing level along an axis of symmetry of the rolling bearing. The sealing device defining a labyrinth for preventing the entry of contaminants into the first sealing level.

A wheel bearing device equipped with: an inner member including an outer ring (2), a hub ring (3), and at least one inner ring (4) press-fitted into the hub ring (3); multiple rows of rolling bodies (5a/5b); a magnetic encoder (9) provided on an end portion of the inner ring; a cover (10) fitted onto the outer ring (2); and a magnetic sensor (11) provided on the cover. The cover includes a large-diameter cylindrical section (10a) fitted onto the outer ring, a step section (10b) protruding toward the inside in the radial direction and contacting an end surface of the outer ring, and a small-diameter cylindrical section (10c) extending in the axial direction from the step section. A portion of the ground-surface side of the small-diameter cylindrical section forms a protruding circumferential surface (S), and a drain hole (10e) is formed in the protruding circumferential surface (S).

Seal assemblies for conveyor idler rolls are provided. In some embodiments, a plurality of subsets of seal components are selectively installable in the seal assembly. In some embodiments, one or more fins are included on a seal.

A bearing sealing device includes two seals (inner and outer seals) sealing the space between the inner and outer races of a bearing to ensure higher seal performance, and also to reduce the area of the inner periphery of the outer race that needs to be ground. The bearing sealing device includes a ring constituted by a metal annulus, and a rubber part. The metal annulus is formed by cold pressing, and has a seal contact surface kept in contact with seal lips of the outer seal. The rubber part includes a press-fitted portion fixed to the inner periphery of the outer race. The inner race has, on its outer periphery, a cylindrical fitting surface to which the outer seal is press-fitted.

A linear roller bearing includes a cylindrical body defining a cylindrical axis and a diameter. The cylindrical body defines a cylindrical body axial length, and a ratio of the diameter to the cylindrical body axial length ranges from 0.75 to 1.1.

A Pulley device for a tensioning or winding roller for a transmission element including a pulley, and a rolling bearing provided with a rotating outer ring, the pulley being mounted on an outer surface of the outer ring, a fixed inner ring, the rings being coaxial and forming a radial space between them, and at least one row of rolling elements arranged in the radial space. The pulley device further includes at least one annular protection flange with a radial body. The flange is fixed to the rotating outer ring by crimping an axially protruding portion of the pulley towards an outer edge of the flange.
