Bertram Haag

Title: Bertram Haag: Innovator in Bearing Technology

Introduction

Bertram Haag, an accomplished inventor based in Uhlfeld, Germany, has made significant contributions to the field of bearing technology. With a remarkable portfolio of six patents, Haag's work focuses on innovative methods and components that enhance the functionality and reliability of bearings in various applications.

Latest Patents

One of Haag's latest inventions is a method for producing a bearing component. This method involves taking a bearing component blank with an iron-based metal substrate, hardening it, and treating it with an alkaline treatment bath to create an iron oxide-based blackening layer. This conversion layer is then compressed using a spherical body to form a bearing component with a protective layer. This process ensures the final layer thickness is less than 95% of the initial layer thickness, optimizing the durability of the component. Haag's inventive approach includes the use of spherical bodies, which can be hard metal or ceramic, and may also serve as components in hydrostatic finish rolling tools.

Another notable patent is related to rolling bearings and the methods used to manufacture them. These rolling bearings consist of an inner ring, an outer ring, and rolling elements placed between them. Haag's design features a coating formed predominantly from tungsten, aimed at preventing white etching cracks, proving to be particularly useful in applications such as wind turbines.
