A sealed universal joint bearing includes a pot-shaped component having a disk-shaped base and a cylindrical wall projecting from a periphery of the base, and an inner surface of the base and an inner surface of the cylindrical wall define an interior of the pot-shaped body. At least one row of rolling elements are configured to roll along the inner surface of the cylindrical wall. A flange in the interior of the pot-shaped component has a flange surface against which end sides of the rolling elements are configured to slip during bearing operation, and the flange surface includes at least one formation configured to reduce a contact area between the flange surface and the end sides of the rolling elements.

A universal joint or other vehicle driveline assembly includes an inner race, an outer race, and bearings positioned between the races. In some embodiments, the components of the universal joint that are in contact with the bearings are selectively processed to be harder than the other non-contact surfaces of the component.

A universal joint includes: a yoke; cups; a cross shaft; a plurality of needles; washers each including; a washer main body portion which has a circular plate shape, and which is disposed between one of the cup bottom portions, and one of the shaft portions, a needle side raised portion which has an annular shape, which is integrally formed on an outer circumference side of one of the washer main body portion, and which protrudes toward the needle side, and a cup bottom portion side raised portion which has an annular shape, which is integrally formed on the outer circumference side of the one of the washer main body portions, and which protrudes toward the cup bottom portion side.

A cross joint comprises a flange yoke and a stab yoke, each comprising a based end portion and a pair of arm portions having a shaft hole and extending from both sides of the base end portion, and a spider having a first shaft fitted into the shaft hole of the flange yoke and a second shaft fitted into the shaft hole of the stab yoke, wherein the cross joint further comprises a flexing limiting portion, which limits a flexing angle of the cross joint due to mutual contact of a protruding portion of the base end portion and a flange portion of the spider when the flange yoke is flexed to a predetermined angle.

The present disclosure provides a stabilizing unit for a medical device. The stabilizing unit includes a retaining arm having a surface configured to abut a surface of the medical device. The stabilizing unit also includes a stabilizing fork having a slot configured to receive the medical device. A biasing member is in contact with the stabilizing fork and is configured to urge the slot of the stabilizing fork towards the retaining arm. When the medical device is placed in the slot of the stabilizing fork, the basing member urges the stabilizing fork against an adjacent surface of the medical device, and an opposing surface of the medical device against the retaining arm.

A structural unit for assembly to a trunnion of a universal joint bearing providing a cup, a sealing ring, which is fixed to the cup, and a shield, which is connected to the cup in a state in which the structural unit is not assembled to the trunnion. The cup includes a bottom and the sealing ring provides at least one sealing lip that points in a direction with an axial component towards the bottom.

A universal joint for vehicle drivetrains and the like that eliminates the spinning of bearing caps relative to yoke years and trunnions and inhibits inadvertent spreading of opposing ears of a yoke away from each other under increasing torsional loads to reduce wear and failure of the joint. Broadly, the disclosed universal joint includes a central body having a plurality of pairs of opposite apertures, first and second yokes that are disposed about the central body over respective ones of the pairs of apertures, and a plurality of trunnions inserted through the yoke ears and into the apertures of the body to pivotally secure the yokes to the body. Each trunnion is non-rotatable relative to its respective yoke and a locking assembly inhibits movement of each opposite pair of trunnions away from each other thereby inhibiting movement of the opposite ears of each respective yoke away from each other.
