Axial - rolling bearing retainer and axial for radial rolling bearing - a method of manufacturing a radial rolling bearing

摘要

The present invention relates to a method for manufacturing a rolling bearing cage (4) for a rolling bearing comprising at least one row of rolling elements (3). In the method according to the invention, a ring or ring element made from a solid metal material is provided, which is formed into an annular or segmented body of a rolling bearing retainer (4) by a forming process and / or cutting, material removal process. Molded. The body (6) has an opening (9) for receiving the respective rolling element (3), the body (6) being heated to a temperature above the minimum coating temperature for thermal coating with the thermoplastic powder, The body (6) is then immersed in a fluidized bed containing thermoplastic material powder, and while the body is present in the fluidized bed, the thermoplastic material powder adheres to the body (6), dissolves, and undergoes a continuous coating ( 7) and after coating the body (6) is removed from the fluidized bed. The invention further relates to an axial-radial rolling bearing comprising the described rolling bearing cage (4).
