Latest Patents
Hajime Tadumi holds a patent for a sealing device for bearings. This invention features a sub-seal lip designed with a slide contact surface that resembles an annular band. As the bearing's rotation speed increases, the centrifugal force reduces the width of the slide contact surface. This design effectively minimizes sliding friction, preventing an increase in torque during high-speed rotation. Even with increased centrifugal force, the slide-contacted state is maintained, reducing the likelihood of the sub-seal lip floating up from the slinger. This innovative sealing device is crucial for enhancing the efficiency and durability of bearings.
