A bearing having an inner ring, an outer ring, and at least one seal arranged between the rings. The bearing including a protective cover that delimits an annular space into which the seal extends and provides an outer annular portion and at least one inner portion disposed radially facing and at a distance from one another, and a connecting annular portion linking the outer annular portion and the inner portion; and at least one means for fixing the protective cover onto the inner ring, the fixing means passing through the outer and inner portions of the protective cover and cooperating with the inner ring.

The bearing provides an outer ring, an inner ring, at least one seal to one of the rings and cooperating with the other ring, and at least one sealing flange. The sealing flange includes a fixing portion to fix the flange to the other ring, an end portion and a connecting portion to connect the fixing portion and end portion. The end portion of the flange is curved and disposed axially facing the connecting portion. The curved end portion and connecting portion define an annular space that open radially towards the other ring. The curved end portion is mounted axially in contact against an outer lateral face of the seal.

The disclosure relates to a rolling bearing for a medical or cosmetic instrument having a bearing inner ring revolving around an axis of rotation and a stationary bearing outer ring, which concentrically encloses the bearing inner ring; wherein in the radial direction to the axis of rotation, a bearing gap is formed between the bearing inner ring and the bearing outer ring and a plurality of rolling bodies is arranged in succession in the circumferential direction in the bearing gap, via which the bearing inner ring is mounted in the bearing outer ring; wherein the rolling bodies are arranged rolling on the bearing inner ring and the bearing outer ring and have a rolling body height in the radial direction; and the bearing gap is covered in the axial direction by a cover disk, which is fastened on the bearing outer ring or on a housing accommodating the bearing outer ring or is integrally formed with the housing or the bearing outer ring, and which jointly with the bearing inner ring forms a radial gap extending in the axial direction with a gap length, which gap has a gap height in the radial direction.

The rolling bearing according to the invention disclosure is characterized in that the gap length is at least 25% of the rolling body height.

A caster hub is provided that includes a housing having a wall with internal and external surfaces and an axial bore defined by the wall. First and second bearings are disposed coaxially in the bore of the housing. Each bearing has a cylindrical inner race and a cylindrical outer race, with the races separated by rolling elements, and the races defining interior and exterior radial end faces of the bearings. A seat is disposed in the bore that is connected to the internal surface of the wall between the first and second bearings. The seat is engageable with the outer races of the bearings at the confronting interior end faces of the bearings. An inner spacer is disposed in the bore between the first and second bearings, the inner spacer being engageable with the inner races of the bearings at the confronting interior end faces of the bearings.

A vehicle wheel bearing includes a wheel hub having a hub flange to which a wheel is mounted; at least one inner ring mounted to one side of the wheel hub in a press-fitting manner; an outer ring provided radially outward of the inner ring and having a mounting flange to be mounted to the vehicle body on an outer circumferential surface; one or more rolling elements provided radially inward of the outer ring; and a sealing member configured to prevent foreign matters from flowing into the wheel bearing. The sealing member includes a first sealing member mounted to the wheel hub or the inner ring; and a second sealing member mounted to the outer ring. One or more elastic sealing lips are provided in one or both of the first sealing member and the second sealing member.

An axle assembly of a vehicle including a differential assembly, a first axle tube including a proximal end adjacent the differential assembly, an opposite distal end, and an axle bore extending therebetween, a first axle shaft rotatably received in the first axle tube, the first axle shaft including a proximal end disposed in the differential assembly, and an opposite distal end extending outwardly from the distal end of the first axle shaft, and a radial bearing assembly including an inner cup, an outer cup and a plurality of roller elements rotatably received therebetween, the outer cup being axially fixed within the axle bore of the first axle tube and the inner cup being axially fixed to the first axle shaft.

A wheel bearing includes a rotating element to which the wheel of the vehicle is mounted and configured to rotate together with the wheel of the vehicle; a non-rotating element fixed to the vehicle body; and one or more rolling elements provided between the rotating element and the non-rotating element and configured to rotatably support the rotating element relative to the non-rotating element. The rotating element includes a wheel mounting flange, and a sensor target used to measure a rotational speed of the wheel is provided on an axial end surface of the wheel mounting flange. The sensor target includes an annular plate portion configured to be mounted to the axial end surface of the wheel mounting flange, and the annular plate portion includes a target portion used for measuring the rotational speed of the wheel and at least one bolt insertion hole.

A bearing provides a first ring and a second ring capable of rotating concentrically relative to one another, and at least one seal provided with at least one sealing lip. The bearing further includes a sealing module providing a carrier reversibly secured to the first ring, the seal being mounted radially into contact with the carrier, a friction ring reversibly secured to the second ring, the sealing lip of the seal coming into contact with the friction ring, and at least one spacing element axially interposed between the friction ring and the second ring.

A rolling bearing providing a first ring and a second ring capable of rotating concentrically relative to one another, at least one row of rolling elements arranged between first and second raceways of the first and second rings, and at least one seal provided with at least one sealing lip. The first ring includes at least one first rolling ring having the first raceway and a first sealing ring secured to the first rolling ring. The second ring further includes at least one second rolling ring having the second raceway and a second sealing ring secured to the second rolling ring. The bearing also further includes a sealing module reversibly secured to the first and second sealing rings.
