Abstract
Ridges are preferably rolled-formed into a long, flat metal strip; and pockets are also formed in the strip with their axes perpendicular to the ridges. The ridges are then flattened to form lateral projections extending into the pockets with the projections serving to retain rolling members placed in the pockets. A predetermined length of the metal strip is wrapped into an annular shape to form the cage.
Claims8
A method of forming a cage for a bearing comprising:
- first, forming laterally separated longitudinal ridges on at least one flat side of a metal strip, then forming rectangular pockets having their long sides perpendicular to said ridges, then flattening the ridges to form projections extending into the pockets;
- and then cutting off a predetermined length of strip.
The method of forming a cage for a bearing which comprises:
- first, forming laterally separated longitudinal ridges on at least one flat side of a metal strip;
- then cutting off a predetermined length of strip;
- then forming rectangular pockets having their long sides perpendicular to said ridges;
- and then flattening the ridges to form projections extending in the pockets.
The method of forming a cage for a bearing which comprises:
- first, forming rectangular pockets in a metal strip;
- then forming laterally separated longitudinal ridges on at least one flat side of the metal strip, with the long sides of the rectangular pockets being perpendicular to said ridges;
- then flattening the ridges to form projections extending into the pockets;
- and then cutting off a predetermined length of strip.

A method of forming a cage for a rolling member bearing comprising:
- forming laterally separated longitudinal ridges on at least one flat side of a metal strip, and forming rectangular pockets having their long sides perpendicular to said ridges;
- flattening the ridges to form projections extending into the pockets for retaining rolling members placed in the pockets;
- and wrapping a predetermined length of strip into a substantially annular member.
