Latest Patents

Ohta's latest patents include a sealing device and a process for manufacturing the same. In his first patent, he describes a method where the radially inner surface of a sealing lip of an oil seal is irradiated to induce a chemical reaction in the material. This process forms hard helical portions that function like a helical groove or rib, effectively pumping oil back to the oil-side. This design provides excellent sealing properties during relative rotational movement between the sealing lip and the shaft, as well as static sealing ability when there is no relative rotation. His second patent reiterates this innovative approach, emphasizing the same principles and benefits.
