摘要： A pre-set bearing assembly provides for a simplified installation within a rotating shaft system. The bearing assembly includes an outer ring, a first and a second inner ring, a first and a second row of rolling elements, and at least one coupling element that couples the first inner ring to the second inner ring, setting the pre-load or end-play of the bearing assembly to a pre-determined range. The outer ring includes a first outer rolling element raceway on a first inner radial surface and a second outer rolling element raceway on a second inner radial surface. The first inner ring includes a first inner rolling element raceway and the second inner ring includes a second inner rolling element raceway.

摘要： A tapered roller bearing (31a) has a plurality of retainer segments (11a, 11d) each having a pocket to house a tapered roller (34a), and arranged so as to be continuously lined with each other in a circumferential direction between an outer ring (32a) and an inner ring (33a). The retainer segment (11a, 11d) is formed of a resin containing a filler material to lower a thermal linear expansion coefficient. In addition, a clearance (39a) is provided between the first retainer segment (11a) and the last retainer segment (11d) after the plurality of retainer segments (11a, 11d) have been arranged in the circumferential direction without providing any clearance. Here a circumferential range (R) of the clearance (39a) is larger than 0.075% of a circumference of a circle passing through a center of the retainer segment (11a, 11d) and smaller than 0.12% thereof at room temperature.

摘要： A seal configured to seal a gap between a first component and a second component to at least partially retain a fluid on a first side of the seal in a space between the first component and the second component, the seal including a seal body having a radially outer periphery and a central opening configured to receive the first component or the second component, at least one sensor configured to detect a characteristic of the fluid and an adapter. The at least one sensor is disposed on the adapter, and the adapter has a first portion extending through the seal body at a location spaced from and radially between the radially outer periphery and the central opening and a second portion axially abutting the seal body on the first side of the seal.

摘要： A bearing assembly comprises a rolling element bearing having an inner ring, an outer ring and a set of rolling elements arranged in a bearing cavity between the inner and outer rings. A first grease is provided in the bearing cavity, which has a first thermal bleed rate at a specific reference temperature. The bearing assembly further comprises a grease cartridge, arranged at an axial side of the bearing cavity, whereby the cartridge has axially extending passageways that open into the bearing cavity, and whereby at least some of the passageways are filled with a second grease. The second grease has a second thermal bleed rate at the specific reference temperature which is lower than that of the first grease.

摘要： A wheel bearing apparatus has an outer member, an inner member, at least one inner ring fit onto the inner member. Double row rolling elements are rollably arranged between the outer and inner raceway surfaces, via cages. A seal is mounted on one end of the outer member. The seal has side lips adapted to be in sliding contact with the wheel hub. The seal has three inclined side lips each extending radially outward from the seal body. The lips are adapted to be in sliding contact with the base of the wheel mounting flange. Interference of the side lips against the base of the wheel mounting flange is set so that the radially inner side lip has a smaller interference than that of the radially outer side lips, in order.

摘要： There is provided a rolling bearing including: inner and outer members, rolling elements in a raceway space, flexible annular sealing members which close openings at both ends of the raceway space, and annular metal shield members. Each sealing member is formed in three-dimensional shape such that the sealing member in a natural state is convex inwardly between outer and inner circumferential edge portions and the inner circumferential edge portion is elastically in surface contact with the outer surface of the inner member when the sealing member is fitted to the outer member. Each metal shield member is fixed to the outer member in a state that the outer circumferential edge portion of each sealing member is sandwiched between the metal shield member and the outer member. Each metal shield member covers part of each sealing member without contacting the inner member.
