Abstract
Abstract A method for making spherical rod end bearings comprising pressing a right cylindrical bushing into a radially uniform semispherical clearance between a ball and a bearing retainer or banjo. A single or double bushing may be used. A new bushing may be used to eject an old one. The retainer is preferably provided with axially oriented annular flats adjacent the opposite ends thereof to lock the bushing into place.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
69 words
A method of making a rod end bearing comprising the steps of: placing a bearing ball in a semispherical retainer to define a substantially uniform semispherical annular clearance between the outer surface of the ball and the inner surface of the retainer; aligning a right cylindrical bushing of substantially uniform radial thickness with the clearance, and pressing the bushing into the clearance to deform the bushing into conformity therewith.
Claim 2
Independent Claim
69 words
A method of making a rod end bearing comprising the steps of: placing a bearing ball in a semispherical retainer to define a substantially uniform semispherical annular clearance between the outer surface of the ball and the inner surface of the retainer; aligning a right cylindrical bushing of substantially uniform radial thickness with the clearance, and pressing the bushing into the clearance to deform the bushing into conformity therewith.
Claim 3
Dependent Claim
34 words
The method defined in claim 1 wherein the ball is initially held in place by a preinserted bushing, the step of pressing the bushing into the clearance causing simultaneous ejection of the preinserted bushing.
Claim 4
Independent Claim
75 words
A method of making a rod end bearing comprising the steps of: placing a bearing ball in a semispherical retainer to define a substantially uniform semispherical annular clearance between the outer surface of the ball and the inner surface of the retainer, aligning a pair of cylindrical bushings of substantially uniform radial thickness with and on opposite sides of the clearance; and pressing the bushings into the clearance to deform the bushings into conformity therewith.
Claim 5
Independent Claim
75 words
A method of making a rod end bearing comprising the steps of: placing a bearing ball in a semispherical retainer to define a substantially uniform semispherical annular clearance between the outer surface of the ball and the inner surface of the retainer, aligning a pair of cylindrical bushings of substantially uniform radial thickness with and on opposite sides of the clearance; and pressing the bushings into the clearance to deform the bushings into conformity therewith.
