A bearing cage includes a circumferential ring element and an axial bridge that meet in a connection region, and the connection region includes a recess formed such that a thickness of the ring element in the connection region is less than a thickness of the ring element outside the connection region and such that a thickness of the bridge in the connection region is not less than a thickness of the bridge outside the connection region.

Bearing cage of a rolling-element bearing

A method for forming a clamping device comprising of a swiveling body made of plastic, a plain bearing bushing mounted radially inside the plastic swiveling body, a rolling bearing for mounting a clamping roll arranged eccentrically to the bearing bushing, the edges of the plain bearing bushing being wound out of a strip, and joined to each other under intrinsic tension in the area of the butt joint; and, wherein, the lateral surface of the plain bearing bushing and the bore surface of the rolling bearing function as parts of a mold for the injection-molding of the swiveling body and consisting of the steps of placing the rolling bearing assembly and a plain bearing bushing in a mold half in eccentric relation to one another, placing a second mold half over the plain bearing bushing and rolling bearing configured to form ring-shaped projections to hold rolling bearing in a predetermined axial position relating to the bearing bushing, and injecting a plastic material with the mold closed to form the swivel body.

Belt tensioner device and method for making same

A support body used in a tensioning device includes a support element and a bottom plate. The support element is attached to the bottom plate in a radially and axially form-fitting and fixed manner through use of a plastic element that is molded into place by extrusion. The plastic element engages a groove formed in the outer surface of the support element and also engages through holes formed in the bottom plate.

Support body for tensioning device

An arrangement for fixing a tubular element, such as a shaft, that is provided with a bore and a flange in position with respect to plate element involves the use of a ball that pressed into the bore in the tubular element. To achieve a simple fixation that is secure in both axial directions, the plate element is fixed on one side by the flange of the tubular element and on the other side by the bulge that is created through insertion of the ball into the bore in the tubular element. The ball has a greater diameter than that of the bore in the tubular element so that insertion of the ball into the bore causes the tubular element to become enlarged, thus forming the bulge.
