Abstract
A bushing is disclosed for use in a pivot system to eliminate lateral looseness of a pivoting member mounted between a pair of support plates. The bushing is placed between one support plate and the pivoting member in an interference fit relationship to provide a retaining force on the pivoting member to hold it laterally in place. By using a compressible nylon of for the bushing having high lubricity, excessive wear of the bushing is eliminated and binding of the pivot system during operation is precluded. The bushing through passage is formed with an enlarged portion at the bushing ends to provide an annular space between the bushing and a pivot pin for compression of the bushing ends.
