Abstract
A device for sealing and/or mounting a rolling-element bearing in a housing or on a shaft includes a sheet-metal disk secured to one of the bearing rings and an annular portion which interfaces with the other ring to form a seal. The disk has a second diverging annular portion which acts like a spring to urge the edges thereof into engagement with the housing or shaft for affixation thereto or to provide a resilient coupling between the bearing and housing or shaft.

A device for sealing and mounting a rolling-element bearing having first and second bearing rings in a housing or on a shaft, comprising:
- a sheet-metal disk secured to one of said first and second bearing rings and having an annular portion extending toward the other of said first and second bearing rings and forming a seal therewith, said disk having a connector section for connecting it to said one ring and a second annular portion, said second annular portion having a diverging surface extending axially outward of said bearing at least before the rolling-element bearing is installed.
A rolling element bearing having inner and outer radially spaced apart bearing rings and rolling elements held therein, and a combined seal and mounting ring affixed thereto, said outer bearing ring having a groove in the bore thereof, said ring having a sealing portion extending from said groove radially inwardly towards the inner bearing ring, a central section held in said groove, and a mounting section extending radially and axially outwardly of said outer bearing ring from said groove in a diverging manner to form an elastically acting cup-shaped spring.
