A rotation-damping rolling bearing is provided with a damping element between a cover or sealing disk and a row of rolling elements. The damping element can be integrally formed with a cover disk, vulcanized on the support body of the sealing disk, integrally formed with the support, or connected to the sealing disk separate from the support. The sealing disk is provided with a flexible sealing lip. The damping element contacts the rolling bodies with axial prestress.

A method and apparatus for manufacture of a rolling body directly on a bearing, comprising a hub, a roller sleeve, an annular portion joining the hub and roller sleeve, and reinforcing ribs on either side of the annular portion. Injected material fills the recesses for forming the reinforcing ribs from two directions: a primary flow radially inwardly directed from the mold portion for forming the roller sleeve and a secondary flow radially outwardly directed from the mold portion for forming the hub. The total cross-sectional area of the recesses for forming the reinforcing ribs is adjusted with respect to the circumferential cross-sectional area of the mold portion for forming the annular portion so that the fronts of the primary and secondary flows meet in the recesses. Pressure-release openings are arranged to communicate with the recesses at points in the area at which the meeting of the flow fronts occurs. The junctures resulting from the meeting of the flow fronts are thereby formed along the reinforcing ribs.

A bearing unit for a rotating component, such as a toothed gear or guide pulley, with an integrated pump consists of a housing with a pump chamber defined therein, a pump rotor installed in the pump chamber, a support pin having an end supported in the housing, and a bearing ring rotatably mounted on the support pin. The bearing unit is mountable on a support surface of an associated machine element, such as an engine block by means of a flange on the housing. The pump rotor and the rotating component are securely mounted on the outer surface of the bearing ring in mutual abutting relationship. The pump rotor is disposed between the housing flange and a web portion of the rotating component. The rim portion of the rotating component circumscribes the pump rotor. A sliding sealing ring is provided between the housing or housing ring and the rotating component.

In a method for fixedly mounting a machine element such as a bearing on a smooth shaft, the material of the shaft is displaced by forcing a stamping tool into an outer surface of the shaft, in a direction at an angle to the axis of the shaft.

An hydraulically operated clutch release has an annular piston hydraulically moveable in an annular chamber. A felt ring is mounted on a shoulder of the piston away from the chamber, to engage the bore surface of the chamber, and a holding ring is snapped onto the end of the shoulder to hold the felt ring on the shoulder. An extension of the holding ring forms a seal with the bore on the chamber, and defines, with the felt ring a dust catching recess.

The invention relates to an hydraulic release arrangement for vehicle clutches or the like and consisting of an annular cylinder axially expanding in the application of the clutch and a release bearing that is affixed to the annular cylinder without special guidance. The annular cylinder is constructed of coaxially arranged tube-shaped spring metal bellows with lateral self-sealing connection rings. Alternatively, a spring metal bellows with a U-shaped profile is used.

Means for securing a machine element such as a bearing assembly on a shaft member or the like provided with an annular groove comprising an angular ring (14) having a radially outwardly directed leg portion (15) which abuts against an axial end face of the inner ring component to be secured and an axial leg portion (16) which is pressed into the annular groove (17) of the shaft or the like at least at a plurality of circumferentially spaced locations about its periphery.

In a non-machining method for manufacturing a solid-bottomed or internally flanged bearing race, especially for rolling contact bearings, the starting material is in the form of a band. For the economical manufacture of this bearing race with an annular groove of extremely precise cross-sectional shape which reduces the wall thickness of the bearing race, and which is situated at the transition from the bottom or flange portion to the race portion, a flat roundel is first stamped from the band. Then a concentric annular groove is worked into one of the planar surfaces of the roundel, while the opposite planar surface thereof is supported on a planar supporting surface. Lastly, the roundel is deep-drawn in a die to form a bearing race having a solid bottom. The end face of the drawing punch concentrically engages the roundel's planar surface that is encompassed by the annular groove. This end face has a diameter that is equal to or greater than the diameter of the radially inner edge of the annular grooves and smaller than the diameter of the radially outer edge of the annular groove.
