The sealed tapered roller bearing assembly (10, 111, 211, 311) of the present invention comprises a bearing assembly (10, 111, 211, 311) which may be removed or serviced without destroying or damaging the assembly (10, 111, 211, 311). Inner and outer races (30, 40) contain tapered rollers (60) there

The sealed tapered roller bearing assembly (10, 111, 211, 311) of the present invention comprises a bearing assembly (10, 111, 211, 311) which may be removed or serviced without destroying or damaging the assembly (10, 111, 211, 311). Inner and outer races (30, 40) contain tapered rollers (60) therebetween, and a positioning ring (70) is disposed intimately about the outer race (40) as a result of the outer race (40) and ring (70) being pressfitted together. The ring (70) extends from an axial portion (76) to a radial portion (78) which becomes an angled feed tapered section (80) that extends into a first end member axial part (82). The tapered section (80), axial part (82) and a dam seal (90) define a lubricant dam area (100) about a first end of a space (95) between the races (30, 40). A second end of the space (95) between the races (30, 40) is enclosed by a composite seal member (120, 121, 221, 321) that has a first resilient foot, end, portion, or arm (124, 125, 214, 312) engaging an axial extension (72) of the axial portion (76) of the ring (70), and a second resilient foot or lip (126, 126A, 224, 324) engaging the inner race (30). For service or inspection, the entire bearing assembly (10, 111, 211, 311) may be removed easily, or just part of the bearing assembly may be removed, all without damaging or destroying the assembly (10, 111, 211, 311).

A bearing assembly, comprising an annular inner race, an annular outer race having an inside diameter greater than an outside diameter of the annular inner race to provide an inner race-outer race annular space, bearing rollers disposed within said space, retaining means spacing said rollers apart from one another, the space having a first diameter at a first axial end which is smaller than a second diameter at a second axial end, and lubricant sealing means disposed about said first and second axial ends, the lubricant sealing means comprising a positioning ring having a first end member disposed over said first axial end and extending to a radial surface of said outer race, the first end member comprising a dam seal extending between the inner race and said ring in order to define a lubricant dam area at said first axial end, the ring formed over said outer race to form a radial portion extending into an axial portion each of which conforms with the shape of and engages said outer race, the axial portion having an axial extension extending axially at said second axial end, and a second end member of the ring comprising a composite seal member extending between said axial extension and said inner race to define a lubricant seal area about said second axial end.
