Abstract
A method for producing a roller bearing cage (1) is provided, including the following steps: a base body (2) which is close to a net shape is produced by a stereolithography method or by a 3D-printing method, and the provided base body (2) is coated with a thin, nanocrystalline coating (3). A roller bearing cage, including a base body (2) and a nanocrystalline coating (3) fixed to the base body (2) produced by this method is also provided. This method is suitable for producing roller bearing cages in only small quantities in a small series.
