Abstract
Abstract An antifriction bearing assembly has rolling elements and a magnetic encoder ring housed in an outer ring with two portions which can have different diameters. A sensor is removably attached to the outer ring in alignment with the encoder ring. Various seal assembly configurations may be used to seal the bearing while accommodating the sensor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
An encoder retainer ring in combination with a magnetic encoder ring on a rotatable shaft, the magnetic encoder ring having a plurality of axially extending fingers, the encoder retainer ring comprising: an annular ring having a plurality of teeth extending radially inward to grip the rotatable shaft and having a plurality of spaces between the teeth, the magnetic encoder ring axially extending fingers extending through the annular ring spaces thereby coupling the annular ring to the magnetic encoder ring.
Claim 2
Dependent Claim
79 words
An encoder retainer ring in combination with a magnetic encoder ring on a rotatable shaft, the magnetic encoder ring having a plurality of axially extending fingers, the encoder retainer ring comprising: an annular ring having a plurality of teeth extending radially inward to grip the rotatable shaft and having a plurality of spaces between the teeth, the magnetic encoder ring axially extending fingers extending through the annular ring spaces thereby coupling the annular ring to the magnetic encoder ring.
Claim 3
Dependent Claim
83 words
A magnetic encoder for use on a rotatable shaft, the magnetic encoder comprising: an annular magnetic encoder ring having a plurality of axially extending fingers; and a retainer ring, the retainer ring being an annular ring having a plurality of castellated teeth extending radially inward to grip the shaft and having a plurality of spaces between the teeth, the annular magnetic encoder ring axially extending fingers extending through the retainer ring spaces thereby coupling the retainer ring to the annular magnetic encoder ring.
Claim 4
Dependent Claim
83 words
A magnetic encoder for use on a rotatable shaft, the magnetic encoder comprising: an annular magnetic encoder ring having a plurality of axially extending fingers; and a retainer ring, the retainer ring being an annular ring having a plurality of castellated teeth extending radially inward to grip the shaft and having a plurality of spaces between the teeth, the annular magnetic encoder ring axially extending fingers extending through the retainer ring spaces thereby coupling the retainer ring to the annular magnetic encoder ring.
