Latest Patents

One of Okayama's latest patents is a rolling bearings and gear shaft support device. This invention features a roller bearing designed to ensure a long endurance life of rollers, even in environments with high debris contamination and temperature rise. The outer ring, inner ring, and tapered rollers are made from a specially formulated steel with increased silicon and manganese contents. After undergoing carbo-nitriding treatment, the material is quenched to achieve a specific amount of retained austenite in the surface layer, significantly preventing surface peeling due to crack initiation and propagation.

Another patent involves a rolling bearing that includes a rolling bearing ring and a rolling element with a diameter of at least 20 mm. In this design, at least one of the components is made from carburized or carbonitrided steel, which contains a precise amount of carbon and nickel. This innovation not only reduces material costs but also enhances fatigue life and optimizes the carburizing time by ensuring surface hardness and case depth.
