A gib includes a metallic substrate having a first face and a second face and an attachment disposed on the metallic substrate. The attachment includes a first functional surface disposed on the first face of the metallic substrate. The first functional surface is configured as a bearing surface. The attachment may be formed of a fabric resin composite material.

This relates to an electrical rotary joint device configured to equip an energy exploitation installation including a first part having an electrical connector and a first electrical track electrically connected to the first connector, a second part having a second electrical connector and a second electrical track electrically connected to the second connector, and an electrical interconnection mechanism configured to electrically interconnect the first and second electrical tracks, with the first part and the second part being movable with respect to each other and defining between them a closed internal chamber in which the first and second electrical tracks and the electrical interconnection mechanism are housed, the latter including electrical contact members that are housed, in particular prestressed, between the first and second electrical tracks and are configured to form rolling deformable contacts between the first and second electrical tracks.

Disclosed is a curved trench ball bearing, which includes an outer ring 1, a set of steel balls 2, a set of retainers 3 and an inner ring 4. The raceways of outer ring 1 and inner ring 4 are used for inlaying steel balls. At least one of them is S-shaped curve arc raceway end to end, the other is linear or S-shaped curve arc raceway. The number of the peak and the number of the valley of the curve arc raceway are equal to or an integer times of the number of steel balls. By means of this structure, a bearing can achieve the displacement of reciprocating rectilinear motion while rotating, thereby simplifying a mechanical structure of a kneading roller.

A vibration exciter apparatus includes an exciter housing and at least one bearing means supporting at least one driven shaft carrying eccentric mass means. The exciter housing has an array of bore passages extending from an upper wall of the exciter housing to a lower wall of the exciter housing and a mounting structure plate securable to mineral processing or handling equipment intended to be vibrated by the exciter apparatus. The mounting structure plate includes an array of fastener receiving zones, whereby elongated fastener means can pass through the bore passages from the upper wall to be engaged in the fastener receiving zones.

A seal-bearing assembly to be inserted into the seal cavity of a mechanical device to provide a seal and a bearing surface to eliminate whip in a rotating, reciprocal, or rotating and reciprocal cylindrical member. The seal-bearing assembly is particularly well suited for use in a reciprocal pump or a piston-driven valve, or between the steam lance and fixed steam tube in a sootblower. The assembly includes at least a pair of outer substantially rigid cylindrical bearings having an inner bore to be positioned over the cylindrical member and at least one complimentary flexible textile packing ring substantially comprised of carbon disposed between the two outer bearing members. In assemblies including an additional bearing, the additional bearing is surrounded by at least one flexible packing on each side. The inner bore of the bearing members provides a bearing surface for eliminating whip of the moving elements in the device.

A sealing arrangement having a rod seal for sealing a cavity for a flowable medium in the region of a rod includes an output apparatus for discharging the flowable medium. The rod is movably supported in a housing to be displaced in an axial direction. The housing has a bearing portion, wherein the rod seal is supported in a fixed manner and wherein the rod extends through the bearing portion and the rod seal so that a first rod portion and a second rod portion are arranged at different sides of the bearing portion. The first rod portion is located at a side facing the cavity and the second rod portion is located at a side facing away from the cavity. The rod seal is arranged at the side of the bearing portion facing the first rod portion and has a first sealing lip and a second sealing lip that are spaced apart from each other in the axial direction and circumferentially contact the rod. The bearing portion facing the cavity has a discharge structure having a support face which circumferentially surrounds the rod. The rod seal is in abutment with the support face and the support face has a diameter which increases in the direction of the second rod portion.

A driving apparatus includes a casing, a driving section, a slider, a coil spring, and a cable including a cable end. The slider includes an engaging section to which the cable end is attached and a spring accommodating section accomodating a part of the coil spring; the slider moves in association with the cable when moving to one side of moving direction by a driving force of the driving section, and moves relative to the cable when moving to the other side of moving direction by a biasing force of the coil spring; and when the slider moves to the other side of moving direction by the biasing force of the coil spring, the coil spring extends while accommodating the cable end in an inner space of the coil spring, thereby reducing the size of the slider and the size of the entire apparatus.

A pivot column bearing is provided for a pivotable fin stabilizer of watercraft, the stabilizer having a column pivotable about a vertical axis. The pivot column bearing includes an upper bearing and a lower bearing, the upper and lower bearings being configured to mount the pivot column pivotably about the vertical axis. At least one of the upper bearing and the lower bearing has spherical guide surfaces.

Provided is a bearing attachment structure for attaching a bearing 71, 72 that supports a rotary shaft 3 inserted into a housing. The bearing attachment structure includes a bearing case 61, 62 including a base portion 612, 622 having a substantially cylindrical shape and a flange portion 611, 621 formed to spread outward from one end portion of the base portion 612, 622 in the axial direction. The bearing 71, 72 is installed in the bearing case 61, 62. The bearing case 61, 62 is disposed by aligning the flange portion 611, 621 with respect to the housing, and the bearing case 61, 62 is welded to the housing at the flange portion 611, 621. This can greatly reduce damage to a bearing caused by welding heat and reliably prevent breakage of the bearing, deterioration of lubricant on the bearing, and a reduction in service life of the bearing.

An exciter apparatus includes an exciter housing and at least one bearing means supporting at least one driven shaft carrying eccentric mass means. The exciter housing includes an array of bore passages extending from an upper wall of the exciter housing to a lower wall of the exciter housing. A mounting structure plate is securable to mineral processing or handling equipment intended to be vibrated by the exciter apparatus. The mounting structure plate has an array of fastener receiving zones, whereby elongated fastener means can pass through the bore passages from the upper wall to be engaged in the fastener receiving zones. The exciter apparatus further includes a pair of bearing members supporting a pair of driven shafts having intermeshing gears. Each of the bearing members and intermeshing gears have individual liquid lubrication sump zones separate from one another, and cooling means for cooling moving parts of the exciter apparatus.
