Latest Patents

Among his latest patents, Watanabe has developed a thrust bearing component. This component is formed of cold-reduced steel sheets and strips, featuring a surface roughness of Rmax ≤ 2 μm. It is produced by cold rolling high-carbon steel that contains 0.9 wt % to 1.2 wt % carbon, 1.2 wt % to 1.7 wt % chrome, 0.1 wt % to 0.5 wt % manganese, and 0.15 wt % to 0.35 wt % silicon. Another notable invention is the needle roller bearing, which includes a steel retainer that retains needle rollers. This retainer is made from a steel plate containing 0.15 to 1.10% by mass of carbon. After forming, the steel plate undergoes induction heat treatment, which includes induction hardening and tempering. This process allows for efficient production in small lots while ensuring high wear resistance and fatigue strength.
