- said upstanding wall having a plurality of raised portions for retaining said bearing assembly within said housing,
- said upstanding wall having a distal edge for engaging an interior wall of said housing, and
- said upstanding wall including at least one retainer tab projecting from said upstanding wall to maintain said annular body in a predetermined location within said housing.
A bearing locating and retaining assembly comprising:
- a nominally cylindrical bearing assembly having a circular cross-section and an annular exterior wall,
- a housing including a relieved portion having an annular interior side wall and a rear wall for receiving and retaining said bearing assembly,
- a bearing retainer having an upstanding annular wall for insertion between said housing interior side wall and said bearing assembly,
- said upstanding annular wall including a distal edge for abutting said housing rear wall,
- a plurality of retainer tabs projecting from said annular body to maintain said annular body in a predetermined location within said housing.
An improved bearing retainer for retaining a bearing assembly within a housing including an annular body for inserting within said housing, said annular body including an upstanding wall defining an interior area and including a rear wall for receiving said bearing assembly and for spacing said bearing assembly from said housing, said upstanding wall having a plurality of raised portions for retaining said bearing assembly within said housing, and said upstanding wall having a lower edge for engaging an interior wall of said housing, the improvement comprising, providing at least one retainer tab projecting interiorally into said annular body at a nominally right angle from a distal portion of said upstanding wall and abutting said rear wall to maintain said annular body in a predetermined location with said housing.
