Abstract
Abstract A bearing with a rotating ring and a radially spaced fixed ring is mounted in the bore of a housing. A seal extends radially across the annulus between the bearing rings. An information sensor support is mounted in the housing and located adjacent one axial end of the bearing. The information sensor mounted in the information sensor support faces the seal. The seal has an axial portion with circumferentially separated holes. The axial portion extends toward the information sensor. The annular information sensor support has an axial portion extending toward the seal. This axial portion has a plurality of circumferentially separated radially extending retainers which pass through the seal holes and into an annular groove formed on the inside surface of the fixed ring.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
158 words
In combination: a housing having a bore for retaining a bearing; a bearing in said bore having a fixed ring and a rotating ring radially spaced from the fixed ring to provide a fixed ring--rotating ring annulus; rolling elements in the annulus which roll on said rings; the fixed ring having an annular groove in its inside surface and axially spaced from the rolling elements; a seal extending radially across said annulus; a radially extending annular support mounted in the housing adjacent one axial end of the bearing; an information sensor mounted in said support and facing the seal, the seal having an axial portion extending toward the information sensor and having a plurality of circumferentially separated holes adjacent the fixed ring annular groove; said annular support having an axial portion extending toward the seal and having a plurality of circumferentially separated radially extending retainers passing radially through said seal holes and into the fixed ring annular groove.
Claim 2
Dependent Claim
158 words
In combination: a housing having a bore for retaining a bearing; a bearing in said bore having a fixed ring and a rotating ring radially spaced from the fixed ring to provide a fixed ring--rotating ring annulus; rolling elements in the annulus which roll on said rings; the fixed ring having an annular groove in its inside surface and axially spaced from the rolling elements; a seal extending radially across said annulus; a radially extending annular support mounted in the housing adjacent one axial end of the bearing; an information sensor mounted in said support and facing the seal, the seal having an axial portion extending toward the information sensor and having a plurality of circumferentially separated holes adjacent the fixed ring annular groove; said annular support having an axial portion extending toward the seal and having a plurality of circumferentially separated radially extending retainers passing radially through said seal holes and into the fixed ring annular groove.
Claim 3
Dependent Claim
12 words
