Abstract
Abstract Randomly placed rolling elements such as balls for anti-friction type bearings may be precisely oriented in individual races or double races by the application of a rotational or oscillatory force. By the application of such force, the rolling elements may be prcisely positioned at spaced intervals throughout the races. An orienting cylinder having at least one notched end wherein each of the notches is of a size and configuration to receive a rolling element is used to orient said rolling elements during the application of said force. One-half of a rolling element retaining cage may be mounted on said notched end of said orienting cylinder to provide convenience in installing the retaining cage after the rolling elements are properly spaced.

Claim 8
Dependent Claim
79 words
A process for orienting randomly placed rolling elements comprising: a. placing an anti-friction bearing sub-assembly with randomly spaced rolling elements in contact with a cylindrical member, said cylindrical member having at least one end spacedly notched such that said notches can receive said rolling elements; and b. causing one of said races to move while the other is held stationary, said movement continuing until each of said randomly spaced rolling elements has been received by one of said notches.
Claim 9
Dependent Claim
79 words
A process for orienting randomly placed rolling elements comprising: a. placing an anti-friction bearing sub-assembly with randomly spaced rolling elements in contact with a cylindrical member, said cylindrical member having at least one end spacedly notched such that said notches can receive said rolling elements; and b. causing one of said races to move while the other is held stationary, said movement continuing until each of said randomly spaced rolling elements has been received by one of said notches.
