A bearing assembly may include first and second rings and a seal assembly therebetween. A stiff element may be coupled to a radial surface of the first ring and a flinger coupled to a radial surface of the second ring. The flinger may include an axially extending portion that contacts the radial surface of the second ring and a radially extending portion. The radially extending portion may be curved in a radial direction, having portions that extend axially inward and outward. A flexible element may be attached to the stiff element and include an axial lip that is configured to seal with the radially extending portion of the flinger. The flinger may be configured such that a misalignment between the flinger and the stiff element, compared to a neutral position, results in a substantially similar interference area between the axial lip and the radially extending portion of the flinger.

A clutch thrust bearing device having a ball bearing with a fixed inner ring, a rotatable outer ring, and at least one series of balls located in a raceway chamber disposed between the rings. The device also provides a piston having a substantially radial portion, the fixed inner ring being in axial abutment against the substantially radial portion. The piston further provides an axial portion arranged in a bore of the fixed inner ring of the ball bearing, the axial portion being provided with at least one outwards radial projection that extends between the fixed inner ring and the rotatable outer ring.

A box type sealing structure including an oil throwing ring and sealing ring with a frame and sealing portion attached to the frame, the oil throwing ring including a centrifugal structure.

A rolling bearing 1 includes an outer ring 1A, an inner ring 1B, a plurality of rolling elements 1C, and a seal member 1D. The outer ring 1A includes a first outer ring 10 and a second outer ring 20. The inner ring 1B includes a first inner ring 30 and a second inner ring 40. The seal member 1D includes an annular base portion 61, 71 fixed to one bearing ring which is one of the outer ring 1A and the inner ring 1B, and an annular protruding portion 62, 72 protruding from the base portion 61, 71 and extending toward a first region which is a region opposing the one hearing ring in another bearing ring which is the other of the outer ring 1A and the inner ring 1B.

A wheel bearing unit includes an outer ring and first and second inner rings and a plurality of rolling elements disposed between the inner and outer rings. At least one of the inner rings has an annular groove formed between an axially outer end of its radially outer surface a radially outer end of its outwardly facing axial end. A seal element such as an O-ring is mounted in the annular groove, and the O-ring is configured and mounted such that a first portion thereof extends axially outwardly of the first outwardly facing axial end and a second portion of the O-ring extends radially outwardly of the radially outer surface.

A lubrication system for a main bearing positioned around a main shaft of a wind turbine includes a seal ring positioned around the shaft adjacent to the bearing, at least one gear adjacent to the seal ring, a mechanical lubricant pump arranged to engage the at least one gear, and at least one lubricant for providing lubrication to the bearing. Thus, as the shaft rotates, the gear(s) drives the lubricant pump such that the pump continuously provides the lubricant to the bearing so long as the shaft is rotating.

The rotary table device includes a base, a motor, a rotary drive shaft and a cross-roller bearing. An outer ring is rotationally driven through engagement of a pinion gear formed at a shaft end of the rotary rive shaft with a rack gear formed on the outer ring and transmission of a rotary drive force from the rotary drive shaft to the outer ring. The outer ring is formed in a hollow cylindrical shape covering a side of an inner ring, includes a table capable of mounting an external member on one side of the hollow cylindrical shape, and is integrated with the rack gear formed over an entire circumference of the other side thereof. With such a configuration, a rotary table device that can realize reduction in height, size and weight can be provided.

This rotative assembly comprises a first element rotating with respect to a second element around a rotation axis, at least one bearing arranged between the first and second element, and at least one sealing element arranged between the first element and the second element. The sealing element is housed in a peripheral groove provided on the first element, and comprises at least one sealing lip resting on a surface of the second element. The first element comprises an extraction groove realized on a radial surface of the first element, and which forms an empty space below an internal surface of the sealing element and creates an axial access to said empty space from an axial end surface of the first element.

A hub-bearing unit having an axis of rotation includes a radially outer ring configured to be stationary, a flanged hub inside the radially outer ring configured to rotate relative to the axis and relative to the radially outer ring, a radially inner ring mounted on the flanged hub in axial abutment with a shoulder of the flanged hub, a front toothing configured to receive a driving torque from a joint, and a retainer configured to receive and form a snap fit seal with an elastic ring connected to the joint, the retainer being located on a radially external cylindrical surface of the radially inner ring and comprising a shaped metal insert and an elastomeric element vulcanized onto the metal insert.
