Abstract
A fastening device for the rollers of a roller bushing, such as a universal joint bushing. The roller bushing includes a pin, an outer bushing around and spaced from the pin and rollers between the pin and the outer bushing. A groove in the outer bushing receives a holding ring which is generally U shaped. The groove in the outer bushing is shaped for receiving the radially outer leg of the holding ring under tension. The radially inner leg of the holding ring has projections which cooperate with projections on an outer seal for snap-holding the outer seal to close off the space between the pin and the bushing. The radially-directed, axially inwardly facing surface of the transition leg of the holding ring rests against the axially inward surface of the groove. Further, an inner sealing element for the space between the pin and the outer bushing rests against that same surface of the transition leg of the holding ring.
