Title: Masato Higuchi: Innovator in Needle Bearing Technology

Introduction

Masato Higuchi is a prominent inventor based in Gunma, Japan. He has made significant contributions to the field of engineering, particularly in the development of needle bearing technology. With a total of 4 patents to his name, Higuchi's work has had a notable impact on the industry.

Latest Patents

One of Higuchi's latest patents is for an outer ring for a shell-type radial needle bearing and its manufacturing method. This innovative design features a cylindrical shape with a bottom, which enhances the fatigue life of the bottom plate section and the continuous section between the bottom plate and the cylindrical section. Additionally, the anti-corrosion characteristics of the outer ring are improved, ensuring that it remains securely in place within the bearing without incurring additional costs. The manufacturing process involves obtaining an intermediate raw material with a cylindrical section and a bottom plate section from a metal raw material. Shot peening is then performed on this intermediate material to create residual compressive stress in the surface and surface layer section on the outer surface side, achieving a residual compressive stress of 700 MPa to 1600 MPa from the surface to a depth of 0.03 mm.
