摘要: A split plummer block bearing housing for a rotatable shaft includes a detachable housing cap, which includes at least one housing grease channel, and at least one seal assembly. The seal assembly includes a stationary part, which has a seal grease channel and is mounted on the housing, and a rotating part that is configured to be mounted on the shaft. The stationary part and the rotating part are configured to cooperate with each other as a labyrinth and/or contacting seal, and the housing grease channel and the seal grease channel connect and form an extension of each other.

摘要: An axial seal assembly includes an inner annular shield having an axial portion disposable about the shaft at a position adjacent to the bearing and a radial portion extending radially outwardly from the axial portion. An outer annular seal has an axial portion engageable with the outer member bore, a radial portion extending radially inwardly from the axial portion and on or more axial sealing lips engaged with the shield radial portion. The seal radial portion is spaced from the shield radial portion by a predetermined axial distance during use. The seal has at least one coupler section engageable with the shield radial portion or the shield axial portion when an axial spacing distance between the seal radial portion and the shield radial portion is less than the predetermined distance to retain the shield coupled with the seal when the seal assembly is separate from an outer member bore.

摘要: A universal joint bearing with at least a first and a second elastomeric ring. The universal joint bearing is free from spiral springs, which exert a force on a portion of one of the elastomeric rings. The portion is provided for abutting against a trunnion of a crosspiece of a universal joint in a condition in which the universal joint bearing is part of the universal joint.

摘要: The invention provides a sealing device sealing a foreign material in a machine outer side so as to prevent the foreign material from entering into a machine inner side, having an end face lip which slidably comes into contact with an end face portion of a rotation side part, and applying grease for lubrication to an inner peripheral surface of the end face lip. In the sealing device, an application amount of the grease applied to an inner peripheral surface of a leading end portion in the end face lip is set to be smaller than an application amount of the grease applied to an inner peripheral surface of a root portion in the end face lip. Accordingly, grease applied to an inner peripheral surface of an end face lip is hard to be scattered even in the case that a centrifugal force acts on the sealing device.

摘要: A wheel bearing apparatus includes a hub shaft having a flange to which a wheel is attached and which is located on a vehicular outer side, an outer ring, a plurality of rolling elements, an annular seal member, and an annular slinger. The slinger has a circular ring portion that is in contact with the flange and a tube portion extending from the circular ring portion toward a vehicular inner side. The tube portion has pawl portions located on the vehicular inner side to engage with a recessed portion of an outer periphery of the hub shaft to inhibit the slinger from being displaced toward the vehicular inner side. The tube portion is further provided with a plurality of slits that is formed along a circumferential direction and that is open on the vehicular inner side. The slits include slits with different depths.

摘要: An intermediate bearing for a drive shaft train of a motor vehicle has an elastic bearing body which has a bore and a supporting ring which is arranged in the bore and has a receiving space for receiving an anti-friction bearing. The receiving space defines a longitudinal axis, and two sealing washers which are spaced apart axially from one another and have in each case one central opening for receiving a drive component. The supporting ring is arranged between the two sealing washers. The sealing washers have in each case one groove which extends concentrically with respect to the longitudinal axis. The supporting ring engages into the two grooves of the sealing washers.

摘要: A shaft includes a head part having an outer diameter greater than an inner diameter of an inner ring and being in contact with a side surface on one axial end side of the inner ring, and a column part extending from the head part toward the other axial end side and having an axial width greater than a bearing. An external periphery of the other axial end portion of the column part is formed with a male screw to be fastened with a support arm. A side surface on one axial end side of the shaft is formed with a concave section to which a tool capable of rotating the shaft is to be fitted. A bottom part of a housing is formed with a through-hole into which the tool can be inserted, at a position facing the concave section.

摘要: Provided is a hub unit bearing wherein a cover can be firmly fitted with an outer ring member, and it is difficult for foreign matter to enter inside through a water drainage hole formed in the cover. The cover that covers the inside end section in the axial direction of the hub unit bearing includes a disk section, a small-diameter cylindrical section bent in the axial direction from the outer perimeter edge section of the disk section and a large-diameter cylindrical section. A cut and raised section that is cut and raised toward the inside in the radial direction is formed in the small-diameter cylindrical section, and a water drainage hole that passes through from inside to outside the cover is provided in the portion that is cut and separated from the small-diameter cylindrical section.

摘要: A bearing sealing device has relatively and coaxially rotating inner and outer members. A first member is fitted onto the inner member, and a second member includes a seal lip portion and a core member fitted into the outer member. The first member has an inner diametrical side cylindrical portion, circular plate portion, and outer diametrical side cylindrical portion. The core member has a cylindrical portion and circular plate portion. A first labyrinth portion is formed along the shaft direction in a gap between the outer diametrical side cylindrical portion and the core member cylindrical portion which face each other diametrically. A second labyrinth portion is formed such that an end face on the bearing space side in the outer diametrical side cylindrical portion faces the core member circular plate portion. A diametrical direction length of the end face is equal to or more than 0.6 mm
