Latest Patents

Hashimoto holds a patent for a roller bearing designed for bearing units. This invention is applicable to under-race lubrication using either an oil air method or an oil mist method. The lubrication oil is directed toward the rolling elements through oil supply channels originating from an annular groove formed in one end face of the inner ring. A V-shaped groove is strategically placed along the edge of the raceway groove of the inner ring, allowing for optimal oil distribution. The outlet ports of the oil supply channels are located in a recess defined by one of the inclined surfaces of the V-shaped groove. This design creates a space between the outlet ports and the rolling elements, ensuring that a sufficient amount of air flows through, thereby effectively supplying lubrication oil to both the rolling elements and the raceway groove. Hashimoto's patent is a testament to his innovative thinking and engineering prowess, with a total of 1 patent to his name.
