Abstract
A method of making a formed body from iron alloys, in particular a cage for use in a radial roller bearing, axial roller bearing or linear roller bearing, includes the steps of treating a metal strip by heat treatment or thermochemical treatment for providing the metal strip with desired properties with respect to hardness, strength and wear resistance, and punching a plurality of spaced slots into the metal strip for formation of pockets for receiving rolling elements.
Claims6
A method of making a cage for use in a radial roller bearing, axial roller bearing or linear roller bearing, said method comprising in succession the steps of:
- treating a metal strip by a process selected from the group consisting of heat treatment or thermochemical treatment for providing the metal strip with desired properties with respect to hardness, strength and wear resistance;
- punching a plurality of spaced slots into the metal strip for formation of pockets for receiving rolling elements;
- and
- rolling the metal strip into a round shape and fusing adjacent ends of the metal strip to form a cage.
