Abstract
Abstract A bearing shim comprising a first end plate, a second end plate and a plurality of spacer elements disposed therebetween. The first end plate includes an axially elongated annular rib adapted to be received within apertures in the spacers and the other end plate. Preferably, the annular rib peripherally circumscribes a bore within the first end plate adapted to receive a rotatably mounted axle therethrough.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
137 words
A bearing shim comprising: a first plate having a central bore adapted to receive an axle therethrough, an annular rib secured to and extending axially outwardly from one side of said plate, said rib being concentric with said bore, a second plate having a central bore dimensioned to receive said rib therein from one side of said second plate, said one side of said first plate facing said one side of said second plate, at least one annular, planar spacer having a predetermined thickness, said spacer having a bore dimensioned to receive said rib therethrough so that, with said spacer positioned around said rib and sandwiched in between said facing sides of said first and second plates, said spacer spaces said facing sides of said first and second plates apart from each other by said predetermined thickness.
Claim 2
Dependent Claim
137 words
A bearing shim comprising: a first plate having a central bore adapted to receive an axle therethrough, an annular rib secured to and extending axially outwardly from one side of said plate, said rib being concentric with said bore, a second plate having a central bore dimensioned to receive said rib therein from one side of said second plate, said one side of said first plate facing said one side of said second plate, at least one annular, planar spacer having a predetermined thickness, said spacer having a bore dimensioned to receive said rib therethrough so that, with said spacer positioned around said rib and sandwiched in between said facing sides of said first and second plates, said spacer spaces said facing sides of said first and second plates apart from each other by said predetermined thickness.
